How Heat Pump Water Heaters Contribute to Global Decarbonization

February 3, 2022

Simply put, decarbonization is the reduction of carbon emissions. The impact of carbon emissions on Earth has sparked heightened awareness and tighter regulations across the U.S. and the world. Because Heat Pump Water Heaters (HPWH) produce zero emissions and dramatically reduce net carbon emissions up to 75%, they will increasingly play a pivotal role in achieving global decarbonization goals.

The most cost-effective way to reduce global carbon emissions is to improve building efficiency. More and more cities, states and countries are imposing aggressive regulations forcing the adoption of cleaner and greener practices. Due to high-efficiency building regulations and gas bans in locations like California and New York, HPWH are becoming the primary option for water heating.
Rheem® now has a heavy-duty HPWH solution. Although they are a relatively new option in the North American market, Rheem’s Commercial HPWH systems have proven performance in Australia for over a decade. Rheem’s Commercial HPWH Split System supports building energy requirements set forth in legislative bills SB 350, AB 758, SB 1477 and AB 3232.

Utility Companies and Initiatives Have a Big Impact with Incentives

California is leading the U.S. in decarbonization funding. The California Public Utilities Commission allocated $435 million in incentives for the purchase HPWHs through 2024. This includes the Self-Generation Incentive Program (SGIP) that provides $44.6 million in incentives for residential and commercial HPWH adoption. Utility companies and initiatives across the U.S. are offering HPWH incentives to homeowners and installing contractors. Check with your local utility company and state to see current available incentives and rebates.

Having system installation options increases the ability to incorporate HPWH into the building design. Rheem offers stackable models and vertical and horizontal exhaust (venting) options. This custom solution makes it possible to install single or multiple units in the best way for each application. With all these options, an engineer or building owner can easily integrate this into a retrofit or new construction project.

Long-Term Benefits of Heat Pump Technology

When reviewing a building’s water heating solution, facility managers think long term as far as energy efficiency, durability, reliability, return on investment and maintenance. Due to its construction, the HPWH delivers in all areas. They are designed for low maintenance costs and high energy savings. It’s easy for plumbers to service with its onboard diagnostics and optional high-level building management system connectivity with Modbus or BACnet information.

For Future Consideration

As the movement towards carbon neutrality continues, new energy and building regulations will shift companies from standard electric and inefficient fossil fuel burning gas water heaters to high-efficiency HPWH. This impacts the future of water heating and carbon reduction goals across the globe.
