Key Information

Air to water heat pumps are only cost-effective in homes that have low heat loss. Simply,  this means that they are well insulated already. Not all homes are suitable for a heat pump grant. Depending on the fabric of the building, in order to be eligible, your home must be built and occupied prior to 2011. The closer to this date your home was built or renovated post 2011 the more likely you are to be eligible without having to carry out any additional insulation works to meet the SEAI standards. In order to apply for a heat pump grant you will need to have a technical assessment carried out by an SEAI registered contractor. This is something Maynooth Heat Pumps experts can provide.

What is an Air to Water Heat Pump?

An Air to Water heat pump is the most modern and efficient way of generating a low temperature supply of water.  A heat pump is the most efficient way of heating your home and your domestic hot water requirements for Irish climate conditions.  Air to Water heat pumps also dramatically reduce CO2 emissions and carbon footprint.

 

Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. It can get heat from the air even when the temperature is as low as -15° C. This makes them very suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

What are the benefits of an Air to Water Heat Pump?

The number one benefit of an Air to Water Heat Pump is lower running costs for your heating.

An air to water heat pump typically costs 50% to 60% less to heat your home than a traditional fossil fuel heating system such as an oil or gas boiler. To simplify it, the ‘efficiency’ of an air to water heat pump is from 320% to 400% or more in comparison to a condensing boiler which has an efficiency of only 92%. This means that for every 4 units of heat put into your house or building,  3 of those units come free from the outside environment.

Because most of the heat energy supplied to your house is free from nature, there is a very low carbon footprint which gives a better energy rating compared to traditional fossil fuel-based heating systems.

What is the Operating Principal of an Air to Water Heat Pump?

Air to water heat pumps extracts their heat energy from the outside air in order to heat your home or business. An air to water heat pump has an outside heat exchanger unit that is like a car radiator but instead of expelling heat to the air it takes heat from the air. The air is pulled through the heat exchanger by a fan whenever the heat pump is on. The air to water heat pump heat exchanger has a refrigerant running through it which is able to absorb heat at a low temperature. Air to water heat pumps can heat your house or building even when it is as low as -15 degrees outside. This refrigerant is then compressed or ‘pumped up’ to a higher temperature by the compressor just like in your fridge. This higher temperature heat is then passed to the water that circulates around through your radiators or underfloor heating to heat your house or to your hot water tank to heat your shower and sink water. The temperature that the air to water heat pump gets from the air may only be at a low temperature but that heat can be pumped up to heat the water to 55 or 60 degrees.

 

From two thirds to three-quarters of the heat energy the air to water heat pump supplies to your home comes free from the air, you are only paying for a quarter of the heat energy you put into your house or building.
