Heat Pump Air Conditioning System Central ASHP Unit Air to Water
Air to water ASHPs
An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system . This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

Maintenance
You can expect them to operate for 20 years or more, however they do require regular scheduled maintenance.
A yearly check by you and a more detailed check by a professional installer every three to five years should be sufficient.
The installer should leave written details of any maintenance checks you should undertake to ensure everything is working properly. Consult with your supplier for exact maintenance requirements before you commit to installing a heat pump. You are likely to be advised to carry out a yearly check that the air inlet grill and evaporator are free of leaves or other debris.
Any plants that have started to grow near the heat pump unit will also need to be removed.
You may also be advised by your installer to check the central heating pressure gauge in your house from time to time. If so, you should be shown how to do this.
