> bad for their future profit/utility/quality of life.

Even EV's suffer this - it's a bore to have to plan your whole life around your EV's battery - detouring to charge up, remembering to precondition and charge up to 100% before you leave, telling the kids not to open the windows because it drains the battery like crazy, if you're travelling with another car, you can't stop in the same place because different cars need different chargers and charge at different rates, etc.

Heat pumps seem to suffer the same - arrive home from work at an unusual time, and a gas boiler will bring the whole house up to temp in 45 mins. Whereas a heat pump will take 6 hours to do the same. Worse quality of life.



First of all, a properly insulated house won't need a huge warming up. And for that, there are timers or these days there is this thing called internet, which allows you to control your home devices from afar.

Actually, I think most transitions to a cleaner future are going to increase our quality of life. EVs beat combustion engined cars in most aspects. Cleaner air benefits everyone.


If your heatpump takes six hours to warm up your home, the system is wrongly designed.


gas systems normally are very powerful because gas is cheap and houses weren't well insulated. The boiler therefore had to be very powerful to overcome losses of the coldest nights, but the rest of the time could heat the building fast.

Heat pumps are far more expensive per btu, both to buy and to run, so it makes more financial sense to insulate the house well and have a heat pump just big enough for the coldest nights losses. But that means that any other time, heating up the thermal mass of the house can take days.

This is only a problem for those who want their house to change temperature.


In my experience neither of your points is true of a modern heat pump nor a modern gas system. All heating systems are generally optimized to bring homes from 16°C to 22°C in about two to three hours. If your heat pump can't do that it's too small (or your radiators are too small). If your gas system can do it in an hour it runs way too hot and you're wasting a lot of gas.
