Please can anyone give advice on heat pumps, I live on the central plateau and my trusty old night store and wood burner are in a state of repair and being 25+ years old parts are not available, so I am looking at installing a heat pump but will keep the log burner in place in case of power cuts or failure of heat pump to do its job.
Size required varies from 8.2 Kw high wall mtg recommended by Mitsubishi to a general recommendation of 10-12 Kw.
Room size 10x5x2.72m. Ceilings insulated and say 30% of walls are insulated, large bay windows with thermo drapes.
We get a fair few frosts and a few mornings down to – 5deg C.
I was going for a Daiken but have been told that Mitsubishi are just as good and a bit cheaper, price is not the main concern I want performance and reliability and I do need a quite one.
Assuming a morning start of say 6:30 is it best to leave the heater on all night at say 10 deg C as opposed to leaving off over night and setting to come on at 6am at 20deg C.
