What are Heat Pumps?

A heat pump is a device that efficiently transfers heat between cool and warm spaces by utilizing a refrigeration cycle. In cold weather, it extracts heat from the outdoors to warm a house, and in warm weather, it can move heat from the house to the outdoors. This method of heat transfer, as opposed to heat generation, makes heat pumps more energy-efficient than alternative home heating methods.

Heat pump systems in Limerick are designed harness heat from sources such as air, water, or the ground. The generated heat is then distributed through radiators, underfloor heating, or warm air units. Notably, heat pump systems heat radiators to a lower temperature compared to traditional boiler systems, and this is particularly beneficial in well-insulated homes. Additionally, with the exception of heat pumps dedicated to providing warm air, these systems can efficiently supply a significant portion of the hot water needs for your home - required for baths, showers, and sinks etc.

Types of Heat Pump Systems

We specialise in the installation of various types of heat pumps in Clare, from air, ground and water pumps. The functions of each type of pump are outlined below:

Air Source Heat Pumps

The most common heat pumping system: air-source heat pump systems extract heat from the external air using an outside unit, eliminating the need for underground piping. This makes them more cost-effective and easier to install than ground source heat pump systems.


Air-to-air heat pump systems distribute heat through air units. Because of this, air-to-air heat pump systems cannot be used to provide hot water.


Air-to-water heat pump systems are the most popular choice of system. Heat is distributed through radiators and underfloor heating and they can also produce hot water.

Exhaust Air-to-Water

Exhaust air-to-water heat pump systems are similar to air-to-water but include mechanical extract ventilation and recover heat from air drawn from the dwelling.

Ground Source Heat Pumps

A ground source heat pump system, or geothermal heat pump system, harnesses renewable heat from the earth. Collector pipework draws heat from the ground, which is then transferred to the heat pump. The ground collector can be positioned horizontally at a shallow depth or vertically at a greater depth.

Water Source Heat Pumps

Water source heat pump systems utilize open water sources such as lakes, rivers, or streams as a heat source. Unlike air source heat pump systems, ground and water source systems involve the additional complexity and cost of installing collector pipework for drawing heat. However, these systems often exhibit more consistent performance, even in colder weather.

What are the benefits of Heat Pump Systems?

There are a number of benefits to installing a heat pump system in your home in Limerick, including but not limited to:

Energy Efficiency: Heat pump systems are energy-efficient, reducing overall energy consumption.

Versatility: They provide both heating and cooling functions, adapting to different seasons.

Environmental Impact: Heat pumps contribute to a reduced carbon footprint, promoting environmental sustainability.

Long-Term Durability: Heat pump systems, when properly maintained, can contribute to the long-term durability of your home in Limerick.

What grants are available in Clare?

The SEAI Heat Pump grant covers a range of heat pump systems and a grant towards your technical assessment. Heat pump grants are paid for first time systems. They are not paid for replacement heat pump systems where a heat pump was already present in the home.
