Heat Pump Systems

Heat Pump Systems are an attractive alternative to fossil fuel heating systems, offering lower costs and reduced carbon emissions.

The Benefits of Heat Pump Systems

More Comfort

Installing a heat pump system in a well-insulated home will transform the comfort levels in your home.

Cheaper Heating Bills

Reduce your heating bills by improving your energy efficiency.

Reduce Your Emissions

No more burning fossil fuels, so you are supporting the environment by reducing your carbon emissions.

How Heat Pump Systems Work

Heat-pumps are electrical devices which convert energy from the air outside of your home into useful heat, in the same way a fridge extracts heat from its inside. In well insulated houses they are very economical to run. They are an extremely efficient alternative to oil, gas, solid fuel and electric home heating systems.

Different types of heat pump systems draw heat from different sources: air, water or the ground. Heat generated is released via radiators, underfloor heating or warm air. All heat pump systems, excluding those providing warm air to the home, can supply all of the hot water needed for baths, showers and sinks.

Heat Pump System Types

Air Source

The most common heat pump systems extract heat from external air, typically using an outside unit. These heat pump systems do not require underground piping to source heat and so can be cheaper and easier to install compared to ground source heat pump systems. The most popular heat pumps are air to water heat pumps.

Ground Source

A ground-source heat pump system uses the earth as a source of renewable heat. Heat is removed from the ground through collector pipework and then transferred to the heat pump. The ground collector can be laid out horizontally at a shallow depth below the surface or else vertically to a greater depth.

Water Source

Water source heat pump systems use open water, such as lakes, rivers or streams, as a heat source. Heat is removed from the water through collector pipework and then transferred to the heat pump.

Ensuring Your Home Is Heat Pump Ready

One of the requirements for a dwelling to qualify for a heat pump system grant is that the dwelling has low heat loss. This is to ensure your heat pump system performs well and your electricity bills are not too high. You can achieve this by insulating your home and/or by upgrading your windows. Note: SEAI also offers grants for home insulation.

Before applying for a heat pump system grant, you must engage an independent, SEAI-registered Technical Advisor. Your Technical Advisor will carry out a technical assessment of your home, and will advise you on what steps to take to make your home “heat pump ready”, i.e. to reduce the heat loss on your home. They will provide you with independent guidance on measures necessary to ensure that the dwelling fabric heat loss is lowered to an acceptable level for a heat pump system to perform effectively and efficiently. The required heat loss level is expressed as a Heat Loss Indicator of 2 Watts/Kelvin/m2.

The Better Energy Homes programme offers a €200 grant towards the Technical Assessment of your home, with this grant only payable in conjunction with the heat pump system grant. To qualify for this funding you must choose your Technical Advisor from the list of SEAI registered Technical Advisors, and complete the heat pump system and any upgrades required according to the programme rules. The list of SEAI-registered Technical Advisors will be available here from April 2018.

Please note that uninsulated homes built more than 30 years ago may require substantial and costly upgrades to qualify for a heat pump system grant.
