Rinnai Headquarters

Hot water: key factsHumans have been heating water since the dawn of time, from

the Roman warm air systems and baths through to specialist

door to door services delivering hot water in 10 gallon jugs. It

wasn’t until the early 2000’s however, that water heating by

continuous flow gas fired systems started to take off in the

UK, forming a paradigm shift in efficiency and performance

and aligning the UK with the rest of the world. Non-domestic

buildings account for 18% of the total carbon emissions with

55% of energy in our non-domestic buildings being used for

delivery of heating and cooling.

Rinnai Corporation Headquarters based in Nagoya, Japan.

Global leaderRinnai is widely considered as a global leader in production

and distribution of gas appliances, reinvesting 3% of nett

sales into R&D to ensure continual product excellence.

Over the past decade, new water heating technology powered

by Rinnai has made a significant difference to the design and

performance of hot water systems.

Continuous flow water heating technology can achieve

over 97% gross efficiency and boast modulation ranges

from 59.5kW to 2.4kW, creating significant energy, cost

and emission savings.

How efficiently the product used and systems designed

operate, can have a big affect on energy and emission

reductions. With outdated hot water systems including

storage type applications, heat and energy is often

wasted unnecessarily through standing losses or system

reheats to ensure high enough water temperatures to

combat Legionella. Some systems can be looking at

standing losses as high as 8kW per 24hrs.

Energy consumption in non- domestic buildings 2011

OfficialFrom September 26th 2015, all water heaters

with an output <400kW and all storage water

heaters up to 500 litres will fall under the ERP

directive with appliances up to 70kW and

cylinders up to 500 litres required to label

their products with an energy efficiency rating

of A+++ to G through the ERP label. We are

pleased to demonstrate that all our technology

is at the peak of performance.

In the past 10 years, Rinnai has pioneered the introduction

of continuous flow water heaters that are capable of supplying

the largest commercial demands, incorporating condensing

technology to achieve the highest efficiencies on the market

without compromising performance.Continuous flow water

heaters from the Rinnai Infinity range can supply in excess

of 950 litres per hour at commercial temperature whilst

performing at 97% gross efficiency and producing less than

20ppm NOx.

Rinnai’s new Infinity PLUS is a custom made water heating

solution that brings together multiple units of our award winning

HDC range of condensing continuous flow water heaters into

single, easy to handle modules.

The Infinity PLUS system incorporates water heaters, skid

systems with cable trays, pipe work and electrical connections

providing the complete pre-fabricated turn key solution. All that

is needed are the final connections to the associated services.

Infinity PLUS has been developed to guarantee the maximum

amount of affordable, ecologically friendly, safe temperature

controlled hot water required at any one time by even the most

demanding commercial user.

Each Infinity PLUS module comprises either two or three HDC

units and as any number of modules can be manifolded, the

capacity is infinite even where demand for instantaneous hot

water peaks massively at certain times of the day.

Cascading water heaters

Note: Common header flue kits are available to further streamline installation. Contact Rinnai for more details.

ONLY Rinnai offers you the complete commercial package:• Any number of Rinnai water heaters can be manifolded

together enabling the largest capacities on the market

• Near mains pressure flow

• CE and WRAS approved

• Low NOx emissions

• Can be set for temperatures as high as 85°C. Heavy duty heaters are ideal for nursing homes, commercial kitchens, hotels, sports clubs etc, as well as domestic situations in larger houses

• Common header flue kits are available to further streamline installation

An optional electronic control system can link each heater,

turning each one on as required.

The system automatically evens out the work load between

units to minimise wear and tear.

If pipework warrants a secondary return system, this can be

achieved by setting the temperature of the water at 65°C.

Multiple heaters can be set up in this way for

larger installations.

A low temperature re-circulation can be achieved by using an

in-line biocide unit with the temperature set at 40 - 43°C.

Hot water storage systems

In situations where a very large demand of hot water

is required, Rinnai Infinity PLUS storage offers a cost

effective solution.

Using a modular system of either internal or external Rinnai

HD or HDC condensing water heaters and a stainless steel

storage vessel, demands in excess of 20,000 litres per hour

can be satisfied.

Rinnai’s stainless steel storage vessels do not require electric

immersion heating elements and these items may be supplied

as an optional extra if required.

The modular system offers the additional benefit of operational

cover should a water heater fail; easy access and isolation of a

unit for servicing.

Rinnai’s Infinity PLUS storage represents a very competitive

and energy efficient hot water solution for larger heavy

duty applications.

Rinnai Condensing Water Heaters can be

used to maintain the temperature in a

large storage vessel.

This approach could be used where the

hot water requirement exceeds the flow

capacity of the manifolded units, or where

there is an intermittent demand for hot

water in buildings such as hotels, hospitals,

apartments, etc.

Renewable hot water solutions

Rinnai offers both flat plate and evacuated tube collectors,

each with specific benefits to suit your application. Either

option will provide years of low maintenance, low cost energy

to heat your water provided the units are correctly sized

and installed.

OrientationBoth flat plate and evacuated tube collectors work best when

facing due south. However evacuated tube collectors will

outperform flat plate collectors when a due south location is

not an option, i.e. east/west facing or both.

PerformanceThe performance of a flat plate collector is close to that of an

evacuated tube collector in the summer months when facing

due south. Evacuated tube collectors have better overall results

in both early and late season and they are not affected

by adverse weather conditions and even produce impressive

temperatures on cloudy days. The flat plate collectors are

exceptionally sturdy and durable, perhaps more suited to

vulnerable locations.

Evacuated tube collectors have multiple glass tubes which heat

up by absorbing the sun’s energy. The vacuum insulated tube

retains most of this heat and the constant profile of the round

tube means that the collector is always perpendicular to the

sun’s rays. The energy absorbed is approximately constant

over the course of the day.

Swimming poolsSwimming pools and jacuzzis are ideal applications for the use

of solar thermal heating because they are generally used most

in the summer when the energy that can be obtained from the

sun’s radiation is at its maximum.

Rinnai can help you to design, size and install a solar heating

system for your swimming pool or jacuzzi that could also be set

up to heat your domestic hot water at the same time, saving

more money on your ever increasing fuel bills.

Hot water boost applicationsFossil fuel is only used when the renewable thermal energy

store is below its set-point, thus reducing the dependency on

fossil fuel and reducing CO2 emission.

Rinnai can provide solar thermal systems with either flat plate

or evacuated tube collectors and solar cylinders.

These products are also suitable for installation with ground

source and air source heat pumps.

Internal flueing systems and accessories

The Rinnai internal flueing system is highly versatile and makes

installation of an internal water heater simple and convenient.

Notes

1 The heater can be flued vertically, horizontally or any

combination of both.

2 Horizontal flueing can be used as a direct through the wall

flue or extended from another internal wall.

3 Vertical flueing is used when the water heater needs to be

flued vertically through the roof.

4 A siphon pack is required when vertical flue

exceeds 1.5 metres.

5 Rinnai Infinity internal water heaters are classified as

‘room sealed’ appliances. Flue systems must be installed in

accordance with Rinnai Installation instructions (supplied

with flue terminals), local gas fitting regulations, municipal

building codes, and all other relevant statutory regulations.

6 A full range of extensions, bends, brackets and flashings

are available from Rinnai.

7 All flue components for the HD50i are 80mm inner

diameter and 125mm outer diameter.

8 90 degree bend is 2m reduction whilst 45 degree bend

is 1m reduction

9 Additionally, the height from top of the heater to the

terminal cannot exceed 9m.

10 Only Rinnai flueing systems must be used with internal

water heaters. Use of non-Rinnai flueing systems will

invalidate the heater warranty.

11 Common header flue kits are available for the

condensing range only.

Controls

Why install temperature controllers?Remote temperature controllers allow precise temperature

control by the user. The water heater will deliver the selected

temperature even when the water flow is varied or more than

one tap is in use.

Each remote controller can be individually programmed,

however the water heater can only deliver one set temperature

at any time.

Remote temperature controllers cannot override the master

temperature setting made with the DIP switches within

the heater.

• 12 volts DC supplied from the water heater (up to 50m cable run)

• 12 hour AM/PM Clock

• In-use indicator

• Diagnostic tool for commissioning

Maximum number of temperature controllersUp to a maximum of four temperature controllers can be fitted

to Rinnai water heaters depending on water heater model.

Any combination of Universal wired or Deluxe temperature
