Re the truth about heatpumps video...
1) House is warmer than it was on an oil boiler
2) House is cheaper to heat that it was on an oil boiler
3) Not burning oil
4) Government scheme required insultation before installation (cavity wall, loft etc.) they would not pay out without cheaper/easier insulation being installed first.
5) Legionalla cycle runs once a week for an hour to kill potential bugs (with current cap and a 1kw immersion this costs 34p), otherwise the hot water is bountiful and still too hot to put your hand under.
6) Lowest COP I have had in 2 years was January at 2.8
7) Heat pump installers are a team including plumbers and electricians
8) Cylinder is smaller than previous combo of header tank and cylinder
9) I can hear my neighbours boiler flue OVER my heatpump
10) No underfloor heating, "oversized radiators" are actually smaller on the wall than our old radiators, we actually had to decorate.
11) WE NEED TO DECARBONISE
I firmly believe that instead of government money being used we should be offered 0% loans payable over 10 years which would easily payback over that period. Roger suggests no reasonable alternative, but insulation is the best first step as it a) reduces the use of gas without replacing and b) makes heat pumps even more viable alternatives once a gas boiler needs replacing
For those who want to dive deeper I'd suggest some better informed source such as
