Air Source Heat Pumps

An air source heat pump works much like a fridge, only it’s in reverse so it heats your home. Outside air is blown over a network of tubes filled with a refrigerant. This warms up the refrigerant and it turns from a liquid into a gas. The refrigerant transfers its heat to water, making it warm. This warm water is send around your radiators or underfloor heating just like a conventional gas or oil system would, heating your home.

Use electricity to heat your home rather than gas or oil

Use solar and batteries to supply electricity to the air source heat pump for even cheaper running costs

Reduce your carbon contribution drastically

We have seen an enormous uptake in air source heat pump installations in the last year mainly due to the fruitious Renewable Heat Incentive. This incentive was due to finish April 2021 and was extended for 12 months.

If you’re considering an air source heat pump, there has never been a better time to capitalise on the generous Renewable Heat Incentive currently available
