Heat Pump basics

The Heat Pump is a fantastic device Renewable Energy for Heating and Cooling from an own Energy Source

Ground Source Heat Pumps Free Heating from own property

Surface Ground

Bedrock

Water System

Exhaust Air

Heat Pumps

• Heating for buildings and

domestic water

• Exhaust air as the heating

source

• Together with hydronic

circulation in new built houses

• Replacement of oil or electric

boilers in connection with

ventilation renovations in old

houses

• Also for large buildings

Air-to-Water

Heat Pumps

• Heating for buildings and

domestic water

• Outdoor air as the heat source

• Complementary to oil heating or

electric heating with hydronic

circulation

• Öljylämmityksen tai

vesikiertoisen

sähkölämmityksen rinnalle

• For both new buildings and

renovations

Air-to-Air

Heat Pumps

• Finland has been the promised

land for electric heating

• Electricity is the heating source in

more than 500 000 houses

• Likewise in 500 000 summer

cottages

• Alternatives

• Large electricity bill

• Air-to-Air Heat Pump

• Wood

• Reduction of in-house

temperature

• Conversion to a hydronic

circulation system

Contribution from different Heat Pump types Assuming 25 000 kWh/a in electricity consumption or 3 000 l/a in oil consumption

1) Electricity and oil 0,13 €/kWh (electricity 13 c/kWh and oil 1,1 €/l with 80% annual operating efficiency)

2) Investment cost including installation, excluding heat delivery system

3) Including ventilation device, excluding channel installations
