120-volt heat pump water heaters (HPWH) are a new technology that can help rapidly decarbonize residential hot water use. Hot water is the second or third biggest energy load in most homes. Thus, electrifying as many water heaters as possible is critical for meeting U.S. decarbonization goals. 120-volt HPWHs are particularly beneficial in retrofit scenarios where the homeowner has a gas-fired water heater and wishes to convert it to a heat pump. Whereas 240-volt HPWHs require expensive electrical work like panel upgrades or new wiring, a 120-volt HPWH can plug into a standard outlet.
In this webinar, you'll learn the basics about 120-volt heat pump water heaters and if they might be a good solution for your home or project. We'll dive into sizing, energy use, and operating costs.
We will review Inflation Reduction Act rebates and tax credits available as well.
Continuing Education Units (CEUS) submitted 1 hour in*

Lessons Learned
1. Understand the basics of 120-volt HPWHs and how they contribute to homeowner welfare and decarbonization
2. Articulate why HPWHs are uniquely positioned to help decarbonize water heating for gas retrofits and improve housing safety
3. Gain best practice information on 120-volt HPWH installations, determining when it is appropriate vs. a 240-volt HPWH, and learn best practices on tank sizing.
4. Be introduced to the human health benefits of switching heat pump water heaters
