  • Something to do with physics. It’s not just about the heat output from a gas boiler vs heat pump. It’s the output from the radiator to the room that matters. For the same output, a gas boiler heats the water to a higher temperature than a heat pump. Which means a radiator gives out more heat to the room. As an extreme example, if it is freezing outside and the heat pump produces a lot of water at 15c, it may have a high thermal output but still wont keep your room warm. If it produces water at 30c, the radiator will transfer some heat to the room, but unless the radiator is very big or the room is well insulated, probably not enough.












  • It depends on the details of the car scheme. A BEV is great, assuming you can charge it cheaply at home, except for the two days where you have a 400 mile round trip. For those, motorway fast charging will get you there and back. I have had a company BEV for 3 years. Worked out ok with lease cost and tax benefits. But I have now decided to abandon the company car scheme and got a private car with a petrol engine. Never saw the point of a PHEV, lugging a heavy battery around while running a small petrol engine. Probably good if you mostly drive around town, but that’s not my use case. For private cars, BEVs are just too expensive, to buy, to insure and to repair. My reasons include:

    I get a cash alternative if i don’t take a company car,

    I can’t claim actual cost for motorway charging, which is very expensive. It works out more expensive per mile than a petrol car (for me, a small modern BEV may work out better) This is the main issue for me as I do long trips fairly regularly.

    My car needs 2 hours to charge even on a motorway fast charger. Normal local public chargers don’t work for me, too slow. The car needs 12 hours on my 7kw home charger.
