Heat Pump Installation in Ireland

A heat pump installation in Ireland is a whole-system job, not a straight swap for a boiler. An air-to-air or air-to-water heat pump draws heat from the outside air and moves it indoors, and the unit has to be matched to the fabric of the house: insulation levels, glazing, radiators or underfloor loops, and how the house is actually used day to day. Because the heat pump runs at lower flow temperatures than a fossil-fuel boiler, the installer usually surveys the property first, measures rooms, checks the existing cylinder and pipework, and may recommend radiator upsizing or additional insulation before any unit is ordered. A proper installation covers the outdoor unit on a suitable base or bracket, the indoor cylinder or fan coil, refrigerant pipework, controls, and commissioning with a heat-loss calculation. The work is typically carried out by a qualified refrigeration and heating engineer, often working alongside an electrician for the supply and a plumber for the hydraulic side. Homeowners in counties like Galway, Cork, Meath or Wicklow will find the practical questions are the same: what size unit suits the house, where the outdoor unit can sit without annoying neighbours, and how the system will be controlled and serviced afterwards.

What shapes the price of heat pump installation

The price of a heat pump installation in Ireland is driven by several things, and none of them can be judged properly without a site visit.
The size and type of unit matters first: a larger output unit or a higher-specification model costs more than a small one, and air-to-water systems generally involve more work than air-to-air.
The condition and layout of the existing heating system is the next big factor.

How long heat pump installation takes

A domestic heat pump installation in Ireland usually takes between two and five working days on site, depending on whether radiators, pipework or the cylinder are being changed. A straightforward replacement of an existing system with reuse of the emitters can be quicker; a full retrofit with new radiators, a new cylinder and electrical upgrades can run longer. Before that, allow time for the survey and the written quote, which may take a week or two depending on how busy the installer is. After the survey is accepted, the unit and materials often need to be ordered, and lead times vary by model and season. Realistically, you should plan for a few weeks from first contact to a completed installation, and longer in the busy autumn and winter months when heating work peaks. Weather matters for outdoor unit work, and access to the house needs to be available on the agreed days. Ask the installer to confirm a start date in writing and to tell you in advance if anything is likely to shift it.

What to ask before you hire

01Before you accept a quote for a heat pump installation, ask for it in writing and make sure it lists the unit make and model, the output rating, what is included in the hydraulic and electrical work, and what is excluded.

02Ask whether the price includes the heat-loss calculation, commissioning, and a handover demonstration of the controls.

03Ask for a copy of the installer's insurance, both public liability and employer's liability if they bring helpers.

04Ask whether VAT is included in the figure quoted and at what rate, because a quote that looks cheaper may simply exclude it.

05Ask who is responsible for making good walls, paths and gardens after pipework and cables are run, and who removes the old unit and packaging.

06Ask how long the work will take and what the daily routine will look like, including whether water or power will be off at any point.

07Ask which professional body the installer is a member of, and ask to see their Safe Electric registration for the electrical side of the work.

08Ask what warranty applies to the unit and to the labour, and whether servicing is required to keep it valid.

09Finally, ask for the names of two or three recent customers in your county you can speak to.

Heat pump installation questions people ask

How long does a heat pump installation take in an Irish house?

Most domestic installations take two to five working days on site, with larger retrofits running longer. The survey and quote usually add a week or two beforehand, and ordering the unit can add further lead time. Ask the installer for a written start date and a realistic finish date for your particular house.

Do I need to upgrade my radiators before fitting a heat pump?

Often yes, because heat pumps run at lower flow temperatures than a boiler and need larger emitter surface area to heat a room comfortably. The installer should carry out a room-by-room heat-loss calculation and tell you which radiators, if any, need replacing. Sometimes adding insulation or improving draught-proofing reduces the amount of radiator work needed.

Where can the outdoor heat pump unit be placed?

It needs a firm, level base or a secure wall bracket, good airflow around it, and enough clearance for servicing. Avoid positions directly under bedroom windows or tight against a boundary where noise could affect neighbours. The installer should walk the options with you during the survey and confirm the final position before work begins.

What should a written heat pump quote include?

It should list the unit make, model and output, the cylinder or indoor components, all pipework and electrical work, controls, commissioning, and making good afterwards. It should state whether VAT is included, what warranty applies, and what is excluded. Ask for the price broken into unit, labour and materials so you can compare like with like.

How often does a heat pump need servicing?

Manufacturers typically recommend an annual service to keep the unit running efficiently and to maintain the warranty. The service usually covers checking refrigerant pressures, cleaning or replacing filters, inspecting the outdoor unit, and testing controls. Ask the installer what their service interval is and whether they offer a maintenance arrangement after installation.

Can a heat pump heat my hot water as well as my rooms?

An air-to-water heat pump can supply both space heating and domestic hot water when paired with a suitable cylinder. The cylinder size depends on how many people live in the house and how much hot water you use. Ask the installer to size the cylinder as part of the survey rather than assuming the existing one will do.
