Heat pumps work fine for home heat, but I specifically mentioned hot water and dryer. Heat pump do not work well for those applications - I considered buying them and checked into it. Your oven also uses resistive heat. Induction can work well, but is underpowered if you are cooking more than 3 or 4 things at once (especially if you also use the oven). You need around double the electric service most homes run to the range (there is no standardized plug for it). Induction is only a replacement for causal cooks, people who make full course large meals will not be happy with it.

It sounds like(yet again) another US only problem. My induction hob here in UK is wired to run at 7.2kW and the last thing I would describe it as is "underpowered" - even with all rings turned on at max power, things will burn instantly. It's a vast vast improvement over a gas range, wouldn't be without it. >>but I specifically mentioned hot water and dryer. I've never in my life have seen a dryer that runs on gas. Is this a thing? >> Heat pump do not work well for those applications What's wrong with heat pump dryers? They are awesome, as long as you aren't putting them in an unheated space like a garage. They use much less energy than condenser dryers and considerably less than vented ones, while being pretty quick.

  Yes, natural gas dryers are semi-common in homes that have natural gas service where I live (Minnesota) due to the fact that it costs about half as much to operate a gas-fired dryer vs an electric one. Nearly everyone has gas furnaces here in MN since it’s significantly cheaper to heat with natural gas in the US, and it gets very cold here.

  Ranges in the US can be wired for 50A * 240v * 80% = 9.6kW, and no, that's not enough. Cheaper homes have 30A for the range which is I guess what you have. > like(yet again) another US only problem I don't think Europeans realize how they sound when they say stuff like that. Especially when your stove would be considered low end in the US. A good stove is around 5 kW, and each burner is 2.5kW = 15kW to run everything at once - basically double the service you have. Unless you want to wire the range and stove separately (which might be an option). > I've never in my life have seen a dryer that runs on gas. Is this a thing? Obviously it's a thing, otherwise why would I say it? Is this a European thing not to have them? Gas dryers cost a bit more to buy (15% more maybe), but much much less to operate (half to be exact). If you have gas service in your home and you buy your own appliances you'll almost always pick that. > What's wrong with heat pump dryers? They are very expensive, and save about half the electricity - but gas dryers also save about half the energy, so there's no point in going for the heat pump. Even if you have no gas service, they cost around double a non heat pump, and it would take 10 years to recoup the money. It's not worth it - all you are doing is generating emissions in the dryer factory instead of your house. Environmentally the gas dryer is better, at least as long as we still burn gas to generate electricity. And don't forget the heat pump dryer takes much longer to dry clothing - at least for my house the dryer is always the bottleneck for laundry, I would never buy one that takes longer!
