Air Sourced Heat Pump.

Zoomup
A person today that I was talking to, that has had a new build home which was required by building regs. to have an air sourced heat pump for heating and hot water, complained that the system was slow to heat or cool as required. He said that he had to have underfloor heating installed. It was slow to warm the rooms on cold days. He recently had the system set to cool the rooms on the very hot recent days. But this morning was cooler and he required heating. Is this normal?

    Back of a fag packet ...


    Average annual mileage in England was 7400 in 2019 - interestingly, it has been declining. Is that because of the increasing number of cars which has made motoring horrid? Source


    Number of licensed cars in UK = 31700000. Source


    So total mileage for cars = 235 gigamiles per year.


    At 4 miles per kWh, that is 60 TWh per year. If the charging rate were constant, divide by 365 x 24 = 6.7 GW required, which isn't a country mile away from DZ's figures. If my fag packet is broken, please let me know.


    As a rough check, an EV would increase our electricity consumption by about 30%


    Back to home heating. Our gas consumption is about 15 times our electricity consumption. So now we are looking at more like an extra 100 GW. Yes, I have to agree with DZ's gloomy analysis even though our energy consumption is a bit above average.
