<p style=”text-align: left;”>@DumfriesDik you are high users, I similarly don’t really know where our usage goes. We do have a number of large-screen TVs but it’s only the two of also and we use the air fryer or microwave a lot of the time add to this a couple of dishwasher cycles each week and washings and that’s about it, nearly forgot the plug-in hybrid which uses about 1000kwh per year and the wives ice maker, that’s on about 15 hours a day.</p>
@Phaedra that’s not good you would hope/expect a new boiler to lower your gas bills.
In preparation of an air source heat pump install I have been running the radiators at 50*C to achieve 21.5*C whole house temperature and, nothing to do with the heat pump, running the hot water at 45*C.
Your 30kwh is for the hot water, you will find your rating for the radiators is likely to be 24ish kwh.
