Heat Pumps for Space Heating in Cold Climates: Costs + Performance

I’ve lived in frigid climates that have four distinct seasons my whole life. These places, like my hometown of Boulder Junction, Wisconsin, and my college town of Bozeman, Montana, have winter daily average temperatures in the range of 10-30 degrees F, and are certainly what you would call “heating dominated climates.” Air conditioning is often not needed at all. These cold climates deserve special considerations when selecting modern heating systems.

Ensuring Central HPWH System Success

Central heat pump water heating (HPWH) systems are the cutting edge in all-electric multifamily buildings in California. These systems promise to significantly lower carbon emissions of buildings while reducing energy costs and providing the same satisfactory hot water delivery performance as gas systems. Accordingly, the California Energy Commission (CEC) has partnered with consultant Ecotope to create Title 24 prescriptive and performance compliance options enabling further market penetration. The groundwork is set for this to become a mainstream technology!
