Well, they have electric boilers, gas boilers, and gas/heat pump hybrid boilers. but not restive/heat pump hybrids. (for houses heated with hot water) I suppose this is because the return temperature to the boiler is already 50 Celsius so the heat pump can’t help you at all

Edit: Oh actually, I was wrong.(and I guess it makes sense. It would suffer the same problems as an electric hybrid) There is no hybrid gas heat pump for hydronic heating. Basically my entire city is hydronic heating so heat pumps are not an option. However

a bunch of my neighbours have heat pumps and I suppose it’s just heating one room in their house and it’s not even connected to the thermostat of their hydronic heater in any way.. Seems pretty silly to me. At least you get an air conditioner out of the deal so that you can use more electricity in the summer.
