I have a meter on the dedicated HP circuit, so I know exactly what the HP is consuming. It is that that enables me to make the comparison with values ...
As it is possible for the FTC to be powered from a separate circuit, should this be the case none of its power draw, including the pumps, will be meas...
I think Occam should get his razor out on this one. The simplest explanation is that the Mitsubishi is not capable of accurately measuring the electri...
@jeh in relation to your house I can see why you suggest 13000kWh is a lot, but it is around the average heat requirement for the UK, and the avera...
An annual gas use figure of 13000kWh, as long as you are close to keeping the entire property at 20° for most of the time, would suggest a 5kW ASHP wo...
All heat pumps will hit the point where their minimum output exceeds the heat being taken out by the heating circuit, not oversizing too much means th...
The output of radiators running at 35° is around half that at 45° – so your radiators would have to be twice the size! And you can't really drop the f...
I posted on another thread which may of some relevance - – I had a similar gas use figure and a similar heat loss figure which with the data from the ...

You would think/hope that energy used in heating a building would be an ideal benchmark to build a system round, but unfortunately it doesn’t seem to ...
