MCS heat pump pre-sale information and performance calculation
Posted by: @johnrI would agree that knowing the peak daily gas consumption is useful, but not the peak hourly or half hourly as the underlying philosophy for efficient heat pump operation is to keep trickling heat into the building at approximately the rate which balances the heat loss. Sizing a heat pump to give a blast of heat means a more expensive heat pump operating at a higher and less efficient temperature.
As I mentioned, a short duration analysis seems to be adequate, but I only discovered after analysing the historical data first. 'Blasts' of energy are best avoided, I agree. I believe that the thermal mass of the fabric of the house comes into play here - internal brick walls rather than framework partition walls will help - and any potential problems will be mitigated by weather compensation. Some pragmatism may be required and an acceptance that on a handful of unusually cold days it may be necessary to add some clothes or supplement the heating. The challenge is to find the 'sweet spot'.
