Air to air heat pump cost in Ireland
An air to air heat pump costs €3,000–€5,000 installed in Ireland for a single-room unit and €5,000–€8,000 for a multi-room system. The SEAI grant of up to €9,500 can cover most or all of that when the system replaces your main heating.
Air to air heat pump prices
| System | Installed price | Heats and cools |
|---|---|---|
| Single-room unit | €3,000–€5,000 | One large room or open-plan area |
| Multi-room system, 3 to 5 indoor units | €5,000–€8,000 | Several rooms from one outdoor unit |
Where the money goes
The price of a single-room system splits roughly in half:
| Item | Cost | Notes |
|---|---|---|
| Indoor and outdoor units | €1,200–€2,500 | Depends on the brand and the output |
| Installation | €1,200–€2,500 | About a day, by an F-Gas registered engineer |
Installation covers:
- Mounting the indoor unit and the outdoor unit
- Refrigerant pipework through the wall
- A condensate drain
- The electrical connection
- Commissioning
What pushes the price up
- An indoor unit on an internal wall, which needs a longer pipe run
- Three or more indoor units on one system
- An apartment or protected building, where the outdoor unit may need approval
Cost after the SEAI grant
SEAI pays up to €9,500 for an air to air heat pump that replaces your main fossil fuel or electric storage heating. It never pays more than the cost of the works.
For an apartment with storage heaters, that can cover most or all of a €5,000–€8,000 multi-room system. A single unit added alongside an existing boiler gets no grant, so you pay the full €3,000–€5,000. See the grant rules.
Air to air cost vs air to water
An air to water heat pump costs €9,000–€14,000 installed and has a grant of up to €14,500. It heats the radiators and the hot water, which air to air does not.
Air to air is the lower-cost choice for one room, an apartment or a small well-insulated home. See what an air to air heat pump suits.
