with some shenanigans and thermally massive sinks (say boilers) heating can be intermittently fed, i don’t think a lot of people (some industries might) are bothering with that for now though. (so not heat pumps but say overtly massive boiler with radiator and a fan attached to central hvac system to provide heat as needed, and heat pump as a backstop). plus winter solar efficiency by default is what 40-60%?
Having boilers in the home would reduce the need for batteries but wouldn’t that be a pretty substantial space and safety issue? Something like radiant floor heating or passive solar might be better but that would have to be built in.
