Air to water vs air to air heat pumps
One heats your radiators and water; the other blows warm or cool air. Which do you need?
Short answer
Air to water heat pumps replace your boiler: they feed radiators or underfloor heating and heat your hot water. Air to air heat pumps are wall mounted units that heat and cool individual rooms but don't make hot water. Most Dublin houses want air to water; apartments and extensions often suit air to air.
Air to water
- Heats the whole home through radiators or underfloor
- Heats your hot water cylinder
- Qualifies for SEAI grants up to €14,500 for a house
- Typical cost: €14,000 to €23,000 for a house before grants
Air to air
- Heats and cools the rooms with an indoor unit
- Doesn't heat water: you need a separate system
- Cheaper and quicker to install
- Typical cost: €3,500 to €11,000 for a house
