Re: Bloody batteries and solar panels
I'm confused, most heat pumps have a COP around 4 at maximum. Are you sure your boiler is only 4Kw? Most are over 20Kw...
My current boiler is 27Kw, in order to replace it in direct thermal energy terms, would probably require a 7-8Kw heat pump, which is close to the 40A breaker. It wouldn't need to be run at full whack most of the time, but when it's very cold outside, the COP also falls, so needs the ability to pump a lot of heat.
Obviously, in the real world a whole lot of other mediations will need to be taken. Like improving insulation, bigger radiators for lower temp. running etc...
