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

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
