A Startup Enters the Heat pump Water Heater Space Focused on a Smart Water HeaterPlus 12 HPWH manufacturers provide a virtual training next week
Happy Heat Pump Week to everyone! Make sure to check out all the great events this week.
There are a lot of heat pump water heaters (HPWH) that have come to market recently. At the beginning of this decade, only a handful of manufacturers were making this hyper efficient water heating product and now we count 13 different brands of just tanked water heaters with more brands and form factors coming. At the nonprofit-led Advanced Water Heating Initiative, we offer every manufacturer the chance to present their product as a way to get information about innovations out to the industry and general public. We’ve profiled new manufacturers getting into the space like GE and Navien, and have also talked with the established market leaders who are bringing updated products to market like Rheem, Bradford White, LG, and A. O. Smith. But all these companies have one thing in common - they are large manufacturers that have been making water heaters or heat pumps for a while. Excitingly, the HPWH market is now starting to attract startups and the first one to market is called Cala who brought out their product late last year. We sat down with the company to discuss how to become a startup in the water heating world, what the journey is like and how their product is differentiating itself from a crowded field.

ProspectSV Creates Industry Guidance Package for Central CO2 Heat PumpsProspectSV launched their Industry Guidance Package for CO₂ Heat Pumps for Large Commercial Buildings. This package was created and compiled by ProspectSV and their project team as part of a California Energy Commission-funded demonstration of Flow Environmental Systems’ ANSWR CO₂ Heat Pump at Lawrence Berkeley National Lab’s FLEXLAB facility. ProspectSV created the Industry Guidance Package for building owners, designers, builders, and operators to be able to learn more about the technology, evaluate it for future projects, and to communicate the key benefits of this system, and CO₂ heat pumps in general.
