2. State of the Art of Solar Thermal Applications

Solar heating for open-air swimming pools have been used for several decades

now and are a well- established technology. However, this does not mean that

this application of solar thermal energy has reached its limits yet.

According to statistics in Sun in Action II, about 3-4.000 m2 of unglazed

collectors have been placed yearly in the 90’s. The estimated production and

sales for 2000 and 2001 is 10.000 m2 yearly.

If we look at the developments over recent years, heating of the pool is too

costly for most swimming pool owners. Existing older conventional heating

systems are however often replaced either by absorber systems or the owners

do without heating altogether.

2.1 Absorber Systems

Systems without auxiliary heating

Solar circuits in public open-air baths are normally operated with a separate solar

circuit or absorber circuit pump. The hydraulic construction is much more

complex than for private swimming pools because of the hygiene requirements.

A system in a large open-air pool functions according to the following principle:

The wastewater is led from the pool into a central water storage tank. This tank

acts as a “water level display” for the whole swimming pool water circuit.

Evaporated water is replaced here by fresh water. The water is pumped through

the filter from the water tank. One (or according to the design of the filter

system) several parallel-connected filter pumps are responsible for this. After

this the water is returned to the pool via the water treatment system.

Figure 2: Circuit diagram of open air swimming pool heating by solar absorber

field

Integration of auxiliary heating

Conventionally operated auxiliary heating is necessary if the pool water has to be

maintained at a constant temperature. Some open-air pools wish to offer their

visitors warm swimming pool water independently of the sunshine, which

requires auxiliary heating when the solar radiation is insufficient.


EIE-06-085 SOLPOOL

Figure 3: Circuit diagram of large absorber systems with additional heating

(DGS, 2008)

Unglazed absorbers

Solar open-air pool heating uses absorbers to collect the energy. The collector

design is characterized by the lack of transparent cover and housing as well as

thermal insulation. This simple construction is possible since the systems operate

with low temperature differences between the absorber and the surroundings

and with relatively uniform return temperatures (10°C – 18°C). The swimming

pool absorber is always made from plastic. The use of unglazed and un-insulated

absorbers for solar open-air pool water heating has some advantages due to the

special operating conditions:

In the typical operating range, with a temperature difference Δϑ between the

outside temperature and the mean absorber temperature of 0-20 K, absorbers

often operate with a higher efficiency than glazed collectors. This can be

explained by the fact that the optical losses (normally about 10 to 15% with

respect to the amount of solar radiation) through a transparent cover do not

arise and that the thermal losses are not so significant because of the low

temperature difference Δϑ. These thermal losses increase with operating

temperatures, which however rarely occur due to the moderate absorber

temperatures found under normal operating conditions. The wind speed is the

decisive factor, which causes losses and hence has a negative effect on the

absorber efficiency. This was established in an investigation of absorber testing

and test results of solar open-air pool heating.


EIE-06-085 SOLPOOL

7

Apart from a few special designs plastic absorbers can be subdivided into two

groups:

• Tube absorbers (small tube absorbers)

• Flat absorbers

The tube absorber is the simplest design. A number of smooth or ribbed tubes

(small tubes) are arranged in parallel and according to the design are connected

together with intermediate webs or by retainers at a given spacing. Absorber

lengths of up to 100 m can be achieved and obstructions like chimneys or

rooflights can easily be circumvented.

In the case of flat absorbers, sometimes also called plate or cushion absorbers,

the channels are linked together structurally. This produces plates of different

dimensions with a smooth surface. This has the advantage that there are no

grooves in which dirt or leaves can accumulate and solidify. The self-cleaning

effect during rain is also better. The influence of the design form on the

conversion factor with different inclination angles can be measured but it is

minimal. Variations of the angle of incidence lead to small differences in the

conversion factor only for flat collectors. In the case of ribbed tube absorbers

they lead to larger variations than with normal tube absorbers.

All absorbers are very easy to handle (see also the installation chapter), thus for

example all common types can be walked on. The following figures show a

summary of the absorbers available on the market and the different methods of

connecting the absorber to the collecting and distributing pipes.

Figure 4: Unglazed absorber field

Solar absorbers are exclusively made from plastic. They can be hard and rigid or

soft and flexible according to the plastic mixture. The use of plastic permits

operation of the solar system with chlorinated swimming pool water. It is

however necessary to consider the chlorine content. A high dose (from about 5

mg/l) can damage the absorber. The exact limits, from which damage can occur,

depend on the plastic composition.

Plastics are also used for pipelines. These are however made from rigid

materials. The following plastics are basically the ones that can be used:

EPDM Ethyl Propylene Diene Monomer

PP Polypropylene

PE Polyethylene

ABS Acrylnitrile Butadiene Styrene copolymer

PVC Polyvinyl Chloride (hard or soft)

2.2 Flat plate collectors

Flat plate collectors

In open air swimming pools flat plate collectors may be installed if also a solar

heating of domestic hot water for showers is required. Almost all glazed flat-plate

collectors currently available on the market consist of a metal absorber in a flat

rectangular housing. The collector is thermally insulated on its back and edges,

and is provided with a transparent cover on the upper surface. Two pipe

connections for the supply and return of the heat transfer medium are fitted,

usually to the side of the collector.

Because of the risk of corrosion of thermal collectors with copper absorbers,

these can only be operated in solar systems for swimming pool heating if a

separate solar loop is installed (i.e. indirect) including an external heat

exchanger.

2.3 Vacuum tube collectors

In special cases, e.g. if there is not enough area for the required absorber

surface or additional applications like cooling are desired vacuum tube collectors

may be chosen.

To reduce the thermal losses in a collector, glass cylinders with internal

absorbers are evacuated in a similar way to Thermos flasks. For evacuated tube

collectors the absorber is installed as either flat or upward-vaulted metal strips or

as a coating applied to an internal glass bulb in an evacuated glass tube. An

evacuated tube collector consists of a number of tubes that are connected

together and which are linked at the top by an insulated distributor or collector

box, in which the feed and return lines run. There are two main sorts of

evacuated tube collector: the direct flow-through type and the heat-pipe type.

Direct flow –through evacuated tube collectors In this design the heat transfer medium is either led via a tube-in-tube system

(coaxial tube) to the base of the glass bulb, where it flows back in the return flow

and thereby takes up the heat from the highly spectral-selective absorber, or

flows through a U-shaped tube.

Figure 7: Cross-section of direct flow-through evacuated tube collector (DGS,

2008)


EIE-06-085 SOLPOOL

11

Heat-pipe evacuated tube collectors In this type of collector a selectively coated absorber strip, which is metallically

bonded to a heat pipe, is plugged into the evacuated glass tube.

The heat pipe is filled with alcohol or water in a vacuum, which evaporates at

temperatures as low as 25°C. The vapour thus occurring rises upwards. At the

upper end of the heat pipe the heat released by condensation of the vapour is

transferred via a heat exchanger (condenser) to the heat transfer medium as it

flows by. The condensate flows back down into the heat pipe to take up the heat

again.

Figure 8: Cross-sectional view of a heat-pipe evacuated tube collector (DGS, 2008)

2.4 Hybrid Systems

In some cases a combination of different collector types may be the appropriate

solution for heating an open air swimming pool. In Germany some examples

exist were a glazed flat-plate collector is combined with an unglazed absorber

field. The flat-plate collector field is thus designed for heating domestic hot water

for the showers while the absorber field is directly linked to the swimming pool

water for heating.

Figure 9: Absorber and flat plate collector for solar heating (DGS, 2008)

Another hybrid solution may be a combination of air collectors and absorbers in

order to use different global radiation input for the different oriented collector

surfaces.

3. Objectives of the action

The energy world has changed fundamentally in the last few years, with high

escalating oil prices and with gas prices following behind. Worldwide energy

demand is increasing very rapidly, and given continued prospects for growth

particularly in China and India, it can be expected that this trend will not reverse

in the near future. It is clear that fossil resources will be depleted within the next

160 years, considering all known resources, which have not been made available.

This shows that using fossil resources is not favourable for any reason,

particularly with regard to the energy supply in the EU, which is estimated to

increase 70 % by 2030. Moreover the burning of fossil fuels results in substantial

emissions of green house gases (GHG).

Figure 11: Development of oil prices from 1960 until 2008 (source:

www.tecson.de)

In most heating applications fossil fuels are still dominating, this applies to the

heating of swimming pools as well. Solar energy, on the contrary, is a

sustainable energy source and does not produce any GHG-emissions. Therefore


EIE-06-085 SOLPOOL

14

the use of solar thermal systems for the heating of outdoor pools contributes to

solve the above stated problems.

Today there is no doubt that swimming pools represent an attractive unexploited

market for solar thermal systems.1 In particular for outdoor swimming pools

solar thermal applications are the best technical solution to generate the

demanded energy for the pool heating as well as for the generation of domestic

hot water (DHW) for showers.

Solar heating of outdoor swimming pools has three significant advantages

against other uses of solar thermal energy as shown in table 1:

Table 1: List of workshops for owners and operators

1 Low temperature differences

because the requirement temperature level is comparatively low

with 18 – 25 °C the use of inexpensive solar absorbers is possible

2 Solar radiation and seasonal operation

the period of the highest irradiation corresponds with the energy

demand periods. E.g. in Central Europe outdoor swimming pools

are operated between the beginning/middle of May until middle of

September. In this period 65 – 75 % of the annual irradiation

occurs

3 Simple system design

the pool water flows directly through the absorbers, therefore the

usual storage tanks are not needed as the pool fulfils this task.

These three positive conditions make outdoor swimming pools to

a very favourable application for solar thermal energy.

The main objective of the proposed project is to develop and implement

campaigns for the increased use of solar thermal systems for the heating

of outdoor swimming pools. One campaign concerns the owners and

operators of these pools, while the second concerns installers of heating and

solar systems. As a result of these experiences, a guideline is produced for the

implementation of similar campaigns in other European Member/Candidate

States. 1 White Paper for a Community Strategy and Action Plan COM(97)599 final (26/11/1997): Energy for the future: Renewable sources of energy

4. Facts and figures of the participant countries and regions

Solar thermal systems are predominantly used to generate hot water and to

augment the heating system in private households. The European market

leaders, i.e. Greece, Austria and Germany, have implemented public policies,

particularly in the starting phase of the market, which have been the key to their

success. In the 1980s, the Greek Government offered financial incentives,

combined with awareness raising activities. Several years after the main support

programmes, the market per capita is 16 times bigger than in Italy. Austria is

the leading continental Europe country in solar thermal. The success is based on

stable, long term public support schemes in several federal states, including

awareness raising, financial incentives, training of professionals, R&D funds and

demonstration projects. Germany is the largest market in Europe built up with

the help of sustainable policies. The financial incentive scheme “MAP” now enters

its 8th year. Awareness raising campaigns at federal and local level have been

implemented. In Germany, the internet platform "RegioSolar" supports

numerous and diverse initiatives such as proKlima-fund, solar festival in

Hannover and solar region in Freiburg.

Solar thermal systems are increasingly being used in both small private pools as

well as in larger community facilities and open air swimming pools. However, in

every country this particular application of solar thermal energy is far from

reaching its full potential.

Germany

According to the general manager of „Deutsche Gesellschaft für das Badewesen

e.V.“, there are around 6700 public swimming pools all over Germany. Out of

those 6700 there are 3200 outdoor swimming pools. The rest are indoor pools

and combined outdoor & indoor facilities (~1800), aqua parks (~300), and

school/learning pools (~1400). The company ZFS-Rationelle Energietechnik

GmbH made a study on public pools with implemented solar thermal systems. At

the end of the year 2007, a total of 799 public swimming pools in Germany were

equipped with a solar heating system, according to the named study. In most of

the cases they are outdoor pools and in rare cases a combination of outdoor and

indoor pool facilities. Fifteen of the listed swimming pools have exclusively indoor


EIE-06-085 SOLPOOL

16

facilities. Another important fact to point out is that 98.5% of the total outdoor

pools and outdoor in combination with indoor pool facilities, use absorbers as a

pool heating system. The remaining 1.5% use collectors.

Figure 12: Yearly installed solar systems and surface area of

absorbers/collectors in public swimming pools in Germany

Figure 1 shows the breakdown in number of systems installed and surface area

in relation to their year of installation. It can be seen that the years 1993 and

1994 were the peak years in terms of surface area of absorber/collector

installed, which were followed by almost a continuous decrease in the following

years. In the last two years the tendency is changing again to higher levels, but

even though those levels are still far behind those of the peak years. Since there

are approximately 3200 outdoor public swimming pools, more than 2400 pools

are potential clients of the solar thermal market.

pool Benshausen installed in 2001

Figure 14: outdoor pool Triptis with a

combination of absorber and collectors


EIE-06-085 SOLPOOL

17

The absorber surface area of implemented thermal systems is mainly medium

and large-size, as it can be expected from public pool facilities, according to the

division performed in SOLPOOL (small up to 100 m2; medium >100 m2 up to

500m2; large >500m2 up to 1000m2). Out of a total of 784 outdoor public solar

heated pool facilities, only 35 lie within the small-size absorber surface area

category. A total of 345 lie within an absorber area between 100 and 500 m2,

and the rest, i.e. 404, belong to the largest pool category.

There are two of the top solar thermal companies specialised in swimming pools

providing relevant data on the number and size of their installed systems. The

company Solar Ripp has installed already a total of 407 absorber solar pool

heating systems in Germany. As it can be seen in Fig. 2, most of the systems,

i.e. a 95,3%, have an absorber surface area smaller than 100 m2. Therefore, it

indicates that they have been mainly focused on small-size swimming pools

either from hotels or private owners. The „Deutsche Gesellschaft für das

Badewesen e.V.“ provides a figure of 625.000 swimming pools in private houses

and gardens, which fall in most of the cases within the small-size pool category.

Although at present there is no available information regarding the total number

of small pools in Germany equipped with solar thermal systems, the number of

the already existing small pools gives an idea of the market potential for this

sector.

different surface area subdivisions

In the case of the company Solar-Anlagen Lange GmbH, they have been involved

in the solar pool heating business since 1986. In their case, a total of 190 pool

heating systems have been implemented until the end of 2007. In their case, as

it can be seen in Fig. 3, they have focused both on medium and large solar

swimming pool heating systems.

Figure 16: Solar pool thermal systems installed by Solar-Anlagen Lange GmbH

Slovenia

In Slovenia there are only five implemented solar thermal systems for the

heating of swimming pools. Most of the implemented systems for heating the

swimming pool water are combined with sanitary water heating and space

heating. The Statistical Office of the Republic of Slovenia, which is the main

institution in charge for carrying out programs of statistical surveys, is not

recording data about the number of swimming pools neither their heating

systems. The only institution in Slovenia collecting some data about swimming

pools is the Slovenian Health Protection Institute, which monitors the quality of

the pool water. According to them, there are 174 swimming pool facilities


EIE-06-085 SOLPOOL

19

According to Slovenian Health Protection institute, there were 174 swimming

facilities with 581 swimming pools in Slovenia in 2007, from which 191 are

outdoor swimming pools.

Figure 17: Percentage of types of swimming pools, Slovenia, 2007 (Source:

IVZ, 2008)

The potential for the use of solar heating in swimming pools in Slovenia is quite

big due to high solar irradiation. The majority of swimming pools are suitable for

solar thermal applications. The potential varies with the source of existing

heating, heat demand and period of opening. Only swimming pools which are

using geothermal energy are excluded. The most

appropriate are swimming pools with longer period of

opening and higher heat demand, while potential in

swimming pools which are open only in short summer

period is limited and should be further estimated from

case to case. A smaller potential exists in the private

houses.

The solar radiation in

Slovenia is about 1.350

kWh/ m² per year while the

range in Germany is

between 700 and 1.100

Wh/m². k

In southern Europe, Italy,

Greece and Spain a

maximum of 1.800 kWh/m²

per year can be reached.

Greece

In the case of Greece, there has not been any official

administrative body for land property registration until

recently. This suggests that private swimming pools

(belonging to private buildings, houses, etc) cannot be

extracted by any official source, a fact that makes it

almost impossible to estimate or even consider their reach much

y interviewing three major companies that share 70% of the Greek market, a

total number and by no means imply the existence of a heating system. An

assumption towards the resolution of such an obstacle would be that it is rather

uncommon to use a heating system of pools in private buildings and houses, as

they are rarely used during the colder days of the year.

Another division of the private sector in Greece refers to hotels and other resorts.

A heating system for a swimming pool belonging to hotels and resorts is

practically desirable, as it may extend the swimming pool usage period to

approximately two months before and after summer. Therefore, assuming that

most of the big hotels and resorts have indeed installed a heating system for

their pools, it is still quite hard to consider and contact all of the owners, as well

as extract the required technical data. This may happen either because of their

unawareness of technical and economical characteristics or a general distrust

regarding economical data of their enterprise.

What seems significant for this project are the athletic o

swimming centres, which mainly belong to the publ

sector and are characterized by high density of attendance

(large number of visitors, independent of weathe

conditions). This makes it almost certain that a heatin

system is installed. A number of interviews were held wit

companies that manufacture and/or install swimming

pools and heating systems (both conventional and solar).

In Greece, approximately

1500 swimming pools

are installed every year,

out of which only 5 - 7%

are outdoor pools with an

installed heating system.

B

general image of the market was established and an estimation of the situation

was relatively easier accomplished. According to those interviews carried out

with manufacturers – installers of swimming pools and heating systems in

Greece, approximately 1500 swimming pools are installed every year, out of

which only 5 -7% are outdoor pools with an installed heating system. Each of

those companies installs 150 – 200 swimming pools per year and mostly for

private customers.


EIE-06-085 SOLPOOL

21

o the collected

An estimation based on online surveys and interviews with tourist organizations,

hotel chambers and swimming pool installers reveals that there are about

150.000 outdoor swimming pools installed. What has been suggested by many

companies is that, because of the climate of Greece, the heating systems for

outdoor swimming pools are not required during July and August. For that

reason, when solar heating systems are installed, the produced heat during that

period is employed exclusively for domestic water heating.

Czech Republic

In the Czech Republic approximately 10 % of the outdoor

swimming pools are equipped with a solar thermal system.

Some swimming pools are heated with fossil fuels, either

coal or natural gas. In the eighties some pools were

equipped with flat plate collectors and more recently heat

pumps and cogeneration units have been installed thanks

to the subsidy policy of the Czech government. According t

information from the Czech pool and sauna association there are 567 public

outdoor swimming pools in the Czech Republic. According to a survey carried out

for this project among those listed pools, 58 outdoor pools are heated using solar

energy and 65 are heated through the means of other sources.

According to statistics of MPO and survey of CZREA minimum 14 large outdoor

pools realised new solar system in last 3 years, it is nearly a quarter of number

of pools with solar systems estimated by CZREA. Total area of new systems is

2137 m2, total area of elder systems is 2206 m2.

There is no evidence of systems installed on small private pools; 70 000 m2 of

absorbers was delivered to retail stores in year 2007.

The area of installed systems in the Czech Republic increased during the

performance of the SOLPOOL campaign by nearly 100 % during last 3 years.

Lyon, France

In the region of Lyon, there are 57 municipalities (1 300 000 inhabitants) with a

total of 47 outdoor swimming pools or a combination of outdoor and indoor

swimming pools. France is one of the first European markets for swimming pools,

with more than 1 million of private swimming pools. At present, more than 3000

firms work in the swimming pool sector: around 200 manufacturers and more

than 2500 installers.

Province of Lecce, Italy

In the Province of Lecce there are no available statistical data about the number

of swimming pools and their heating systems. The only available data has been

produced by the tourist office of the Province of Lecce (Hotel, Camping, etc.).

According to their information there are about 100 swimming pools and six

hotels are equipped with a solar system for the heating of sanitary water.

In Lecce there are about 10 public outdoor swimming pools but at present none

of them have an implemented solar thermal heating system. The 10 indoor

identified pools use a conventional heating system.

5. Grant schemes

Although the operating costs of solar thermal systems for outdoor swimming

pools are clearly lower than those of conventional systems, the initial investment

costs of the former are relatively higher. Therefore, it is necessary to support the

implementation of such systems with regional or national grant schemes. The

participating regions and countries have identified the following schemes

accordingly:

Germany

In Germany a grant scheme from „Kreditanstalt für Wiederaufbau (kfw)“ in

Frankfurt, has been identified. The programme started on 2007 and it offers a

credit with reduced redemption to local authorities, owners and operators of

swimming pools to implement solar thermal systems. Local authorities can apply

directly to KFW, however the rest of the applicants must apply via their home

bank. The solar thermal system must have a collector area greater than 40 m2.

For outdoor swimming pools 80% of investment costs are financed by credit,

whereas 30% of the redemption amount is to be remitted.

More information can be found at www.kfw.de

Slovenia

There are currently two identified subsidies for solar thermal systems. The first

one comes from the “Slovenian Environmental Public Fund”. The scheme

supports the implementation of solar thermal systems in residential buildings for

owners up to a 25% of the investment but no more than 150€ per m2 for flat

7. Dissemination materials and tools

SOLPOOL flyers

Flyers dealing with basic information on solar heating of outdoor swimming pools

and the objectives of the SOLPOOL project were prepared. More than 1000 flyers

were produced in 8 languages, bringing information about the project and

additional technical and economic information to the stakeholders. The leaflets

were distributed in the workshops and in different conference. They are available

in the web page http://www.solpool.info/2499.0.html.

Figure 25: SOLPOOL flyer in English

Manuals for end users and for operators and installers

Two types of manuals were prepared in the frame of SOLPOOL, targeting end-

users, and installers and operators in 8 different languages. The first manual, a

booklet of 12 pages intended for end-users, describes the concept of solar

energy, its advantages for heating outdoor swimming pools, the types of

absorbers, the typical design, the basic requirements for implementation,

planning and dimensioning, costs and yields, options for national financing, and

the “5 steps to a good solar system”. The second manual, a booklet of 16 pages,

includes additional technical information, as it was produced for installers and

operators, such as the components of solar thermal systems for outdoor

swimming pools, available concepts/designs, the differentiation among systems,

installation, operation and maintenance. The manuals produced in 8 languages

are available in pdf format for download from the website

A Szent István Egyetem területén található gödöllői városi strand egyik medencéjé-nek vizét részben napenergiával melegí-tik. A napsugárzást hasznosító rendszer 18 db üvegezett síkkollektort tartalmaz, melyek felülete összesen 33,3 m2. A kol-lektorok 45 fokos szögben megdöntve áll-nak és déli irányba néznek. A kollektorok által összegyűjtött hőenergiával nyáron a 700 m3 térfogatú úszómedence vizét fűtik, míg az év további részében a nap-energia hozzájárul a szomszédos óvoda használati melegvízének készítéséhez. A 2000. július 1. és december 31. közöt-ti monitorozási időszakban a kollektorok 4.3 MWh napenergiát hasznosítottak és ezzel 470 m3 földgázt takarítottak meg. A rendszer a Szent István Egyetemen okta-tási célokat is szolgál.

A Szent István Egyetem területén található gödöllői városi strand egyik medencéjének vizét

részben napenergiával melegítik. A beruházás 2000-ben készült el és a 7,3 millió forintos

beruházást a Földművelésügyi és Vidékfejlesztési Minisztérium, valamint Gödöllő Város

Önkormányzata együttesen finanszírozta. A napsugárzást hasznosító rendszer 18 db

üvegezett síkkollektort tartalmaz, melyek felülete összesen 33,3 m2. A kollektorok 45 fokos

szögben megdöntve állnak és deli irányba néznek. A kollektorok által összegyűjtött hőenergiával

nyáron a 700 m3 térfogatú úszómedence vizét fűtik, míg az év további részében a napenergia

hozzájárul a szomszédos óvoda használati melegvízének készítéséhez.

A 2000. július 1 és december 31. közötti monitorozási időszakban a kollektorok 4.3 MWh

napenergiát hasznosítottak és ezzel 470 m3 földgázt takarítottak meg.

A rendszer a Szent István Egyetemen oktatási célokat is szolgál.

The Impact Advisor

The Impact Advisor is a basic decision tool for policy makers or investment

decision makers to pursue the idea of solar pool heating. The simple excel based

Impact Advisor software tool provides the following technical capacities:

calculation of dimensioning, building and operation costs, economic gains, energy

savings and reduced CO2-emissions for solar pool systems against the existing or

conventional heating. The impact advisor is available in English, German,

Slovenian, French, Czech, Greek, Hungarian and Italian in the following link

http://www.solpool.info/2104.0.html.

Figure 28: SOLPOOL Impact Advisor

The Impact Advisor is accompanied by an instruction manual as well as by a

guide for feasibility checks.

Information panels

The consortium prepared 8 information posters (in English, Czech, French,

German, Hungarian, Greek, Italian and Slovene), which are currently being

displayed at more than 200 swimming pools in Europe. Two different posters

were produced according to the needs of the participating countries and regions.

8. Guidelines

Two important guidelines have been produced:

Guideline for SOLPOOL campaigns

This is intended as a guideline for the design and implementation of similar

promotion campaigns for solar swimming pool heating in other European

Member/Candidate States. The process starts with the identification of key

stakeholders and target groups, so that the level and scope of the dissemination

process can be established. Subsequently, the best dissemination tools and

strategies for the implementation of campaigns are defined.

Guideline for the continuation of SOLPOOL promotion

This is intended as a guideline for the consortium members in order to continue

with the SOLPOOL project promotion activities. The idea is to ensure the

sustainability of the project after the end, guaranteeing that the efforts of the

SOOLPOL partners in producing the material and building-up the network of

stakeholders are not in vain. Applying the strategies proposed and following the

suggestions given will ensure that the message of SOOLPOL, promoting the use

of solar swimming pool heating, continues to be brought to the target regions.

9. Impacts of the project and future activities

Overall objective of SOLPOOL project is the increase share of outdoor pools

equipped with solar thermal systems for heating the pool water. Rising

awareness by performing seminars and workshops using target orientated

information material and showing good practice examples all over Europe have

been the main issues the project team has worked on. Comparing the results in

the different partner regions it is evident that the SOLPOOL activities arouse

interest not only of the general public but also of owners/operators/installers as

the core target groups. By dozens of publications and consumer fair

participations a wide audience could be informed about the potential of solar

outdoor pool heating. Depending on the boundary conditions like market size,

funding programmes and weather conditions the solutions for solar heating of

swimming pool water varies as the case arises. Especially in the countries whit

very low ratio of solar heated outdoor pools a lot of installers could be informed

about the technology and were motivated to open this new business field for

their companies. In total 132 new pools were equipped with solar absorber

system in the project period and several individual consultations performed.

By elaborating a campaign manual and providing all deliverables on the project

home page the basis for multiplication of the SOLPOOL campaign in further

European regions and countries has been provided.

In specific, the project’s technical help desks will remain active to provide the

necessary support to potential installers or other stakeholders interested in

installing a solar thermal system for heating an outdoor swimming pool.

Moreover, the English and national pages of the project’s website will be

continuously updated, when important information is met on the respective

topics. In addition, the published informational material produced during the

whole project will keep on being promoted in the framework of the partners

activities (workshops, fairs, etc) that share subjects related to the SOLPOOL

project

10. Cooperation with other projects and programmes

During the project lifespan SOLPOOL project has collaborated with several other

IEE projects like SOLCAMP, SOLARGE, SOLAIR. All projects have a lot in common

- mainly they are focussing on bigger solar thermal systems. SOLPOOL project

partners are involved in several IEE programmes:

• Province of Lecce is working in SOLAIR. The objective of SOLAIR is to

promote and to strengthen the use and market implementation of solar

air-conditioning (SAC) systems. Focus is given – in addition to other

current projects in this field – to small and medium sized SAC systems in

the residential and commercial sector, combining domestic hot water

supply and space heating with air-conditioning. The Province of Lecce

works as a link between the SOLAIR and SOLPOOL project and ensure the

ongoing exchange.

• The SOLPOOL co-ordinator DGS also co-ordinates the EIE project

SOLCAMP – Solar Energy for Camping Sites. The overall objective of

SOLCAMP project is to increase the use of solar thermal systems on

camping sites in the participating regions and countries. Main activities

within SOLCAMP are the training of SolarCheckers, the development of a

simulation software and an intensive campaigning. Thus, a permanent

exchange between both projects is guaranteed. Especially, the network

developed in the frame of SOLCAMP will be used to distribute SOLPOOL

information as the project newsletter and advertisement of the final

international conference e.g. The SOLPOOL co-ordinator DGS cooperates

in the frame of its daily business with the German EIE SOLARGE project

partners Bundesverband Solarwirtschaft (BSW) e.V., Berliner

Energieagentur GmbH and target GmbH (Project co-ordination).

Additionally, DGS participated in dissemination events of SOLARGE as e.g.

in June 2007. The EIE project SOLARGE is a European co-operation project

to open up markets for large collective solar thermal systems for multi-

family buildings, hotels, public and social buildings.

• ApE is also partner in SOLCAMP project. In SOLCAMP ApE is collaborating

together with International tourism institute, one of the important national

institutions in the field of tourism. ApE is already using the established

SOLCAMP network of solar thermal systems and camping sites for current

and future SOLPOOL activities. Furthermore ApE is collaborating with

Slovenian solar thermal technology platform, which is the main institution

for solar thermal sector development in Slovenia.

• CRES is a partner in both SOLPOOL and SOLAIR projects. Bear in mind this

fact and after consideration of the potential synergies among the two

projects, as it was discussed during the SOLPOOL project meeting in


EIE-06-085 SOLPOOL

41

Athens, two events were finally organised and supported by both projects.

The reason of choosing this strategy was mainly guided by the nature of

the target groups, which for both projects are very similar. Moreover,

based on this fact such cooperation would have just positive effect for both

projects, as it would enhance the dissemination impact at the regions

where these events were held (Crete & Thessaloniki).

11. Conclusions and recommendations

The multiple dissemination activities carried out in the SOLPOOL project have

provided a lot of valuable information on how to carry out campaigns in the most

effective manner. As a result of the project experiences, it can be said that future

activities should always be planned in combination with parallel relevant events

of great interest were target audiences are involved; we recommend this when

talking about campaigns at a national level. The national level campaigns should

be mainly implemented in small countries or in countries where the market

potential is limited. However, for cases with great market potential we would

recommend a local/regional approach, using not only regional and local energy

related events to disseminate the SOLPOOL information but also local radio

stations and tv channels amongst others.

In some cases it has been difficult or even impossible to involve the umbrella

organizations of the target groups to act as partners or supporters. To solve this

problem efforts have been made to win members of the stakeholder community

as confederates. In case of SOLPOOL the planning engineers and producers of

solar absorbers could be won to support the activities. This has the advantage

that they have direct link to their clients and economical interests. During the

development of SOLPOOL project, it became apparent that the market and

potential for solar heating of outdoor pools vary from country to country or has

been comparatively rather small with regard to the specific boundary conditions.

Thus the application has to be enhanced from public outdoor pools to private

hotel pools and even indoor pools. Consequentially the target group has to be

changed and e.g. hotel owners have been included.

For future projects it is highly recommended to set performance indicators linked

to big investments not too ambitious. The process from arising the awareness

until the decision for investment takes normally quite some perseverance.
