Reply to comment by fuzzywuzzy1988 in New dwellings in Washington state must be warmed by heat pumps, rather than furnaces, beginning in July, state board rules Friday by BarnabyWoods

Yeah, but they're still more efficient than conventional forced air. The best low-temp heat pumps are 188% efficient at 0 F.

Efficiency and effectiveness are two different things.

Sure, and that was something that was a sticking point decades ago. Modern heat pumps work fine in conditions commonly found in WA, and that's before even looking at the geothermally sunk ones. It is a complete non-issue for them.

Literally the only downside to a good heat pump install is the up-front cost, and since it's new construction and there are big credits right now anyway, that's a no-brainer.
