How do heat pumps work?

Heat pumps collect ambient heat from the air, ground or water. Using a small amount of electricity, they produce enough energy to provide all the heat and hot water you need. No additional heating is required if the system is sized correctly using the data collected from a heat loss calculation.

Benefits of installing a heat pump

Reduced heating bills

A well designed and installed heat pump can be over 300-400% efficient. This means that for 1 unit of
electricity, you generate more than 3-4 units of heat and hot water


Grant funding payments

Heat pumps are eligible for the Renewable Heat Incentive (RHI). The scheme pays you money,
based on how much heat and hot the system produces.


Reduced VAT rated

Heat pumps qualify for reduced VAT rate of 5% in existing homes and 0% in domestic new builds as
they are an energy efficient product.


Reduced carbon emissions

Heat pumps consume less fossil fuels. This helps to achieve Part L Energy Efficiency Building
Regulations and helps to achieve a low carbon future.


Easy to live with

Heat pumps automatically adjust their output to ensure you only get the heat needed to maintain your
desired room temperature.



Heat pumps increase safety in the home as they do not burn fossil fuel so eliminate the risk of carbon
monoxide poisoning.



The lifespan of a heat pump is twice that of a traditional boiler to reduce long term maintenance and
replacement costs.
