(Electricity producers waste a lot of heat energy making electricity.
If you make the electricity @Home the useful heat is free rather than wasted.
Or; free electricity for the same heat)
This seems to be
a quiet Natural Gas Fuel Cell that produces 4.2 KW of electricity and 7.5KW of heat, for 5600 USD.

We don't have a gas supply network here, so it's not much use to me, but depending on gas and electricity prices in your area, this may be worth consideration?
I'm also not signed up on Alibaba (to chat) and want to avoid doing so, so haven't asked questions like: " do you just plumb it in downstream of your boiler? What about warm air for the HVAC system? etc...
