Switch to electricity for radiant heating and DHW
I have an old home in Seattle, WA. It has old style radiators for heating. We have a gas system in the basement that heats both the radiators and our hot water. It is efficient, but I want off fossil fuel. I was thinking about going to a system with a heavy use heat pump hot water tank that will do DHW and maybe heat the loop up to 120F or so via a heat exchanger for the mild heating months. When it gets colder, I thought a small electric water heater could do the peaking. Is this worth a shot or should I go straight to the new heat pumps that are made to do this, but are more expensive.
Thanks for any help you can provide.
