just wondered if anyone has a hybrid heat pump or a microwave boiler - these were suggested to us by the grant scheme instead of an airsource heat pump, which we have been refused owing to not having wall insulation.
The information I have so far about the hybrid heat pump is that it will run on 70% air source and 30% gas in colder months. The model I have been asked to consider is the Daikin Altherma Hybrid air to water gas condensing heat pump.
As for microwave boilers , I haven’t heard of these before, but came across this link
Obviously, like every other householder trying to decarbonize and decrease their energy consumption, while preventing their bills from sharply increasing - I have lots more questions than I started with on my retrofit journey.
These new developments and possibilities are all very interesting , but it feels wise to wait for more information on performance.
