Plumber (HPWH Installation Specialty Only)
For Heat Pump Water Heaters (HPWH) installers, whose role includes providing system design and installation of HPWHs. The curriculum begins with a general overview of heat pump water heater technology including customer experiences and the differences between HPWH and conventional gas/oil water heaters. Decision guidance covers determining the ideal HPWH installation location, and size of HPWH to meet the residences needs. Next, the curriculum covers the Installation process for HPWH. Lastly, the HPWH installer will know about the benefits of smart grid interactions and be able to install devices that enable them.
This curriculum is recommended for Plumbers, Pipefitters, and Steamfitters, US Department of Labor SOC 47-2152.00, and supports the Heat Pump Water Heater Installation Recognition Program.
