Frequently asked questions

How much does a Daikin Altherma heat pump cost in North West England?

Can I get the grant on a Daikin Altherma heat pump in North West England?

Yes, if your home qualifies: the Boiler Upgrade Scheme is not tied to a brand, as long as the installer is MCS-certified. It comes straight off the quote.

What would a Daikin Altherma heat pump cost to run in North West England?

That assumes a 45°C design flow temperature, estimated from its MCS-certified SCOPs of 4.47 at 35°C and 3.54 at 55°C.
