US-based home electrification company Jetson Home has unveiled a new residential heat pump water heater that reportedly uses around 75% less electricity than conventional electric storage water heaters.
The Jetson Water system is available in three storage capacities of 50 gallons (189 liters), 65 gallons (246 liters) , and 80 gallos (303 liters), with a uniform energy factor (UEF) ranging from 3.75 to 4.00, depending on the model. According to the manufacturer, conventional electric tank water heaters typically have a UEF of slightly below 1.0. UEF is a measure of the energy efficiency of water heaters. It indicates how efficiently a water heater converts energy into usable hot water under standardized testing conditions.
“Jetson Water costs $4,495 for the 50-gallon model, $4,995 for the 65-gallon and $5,495 for the 80-gallon, including permits and electrical work,” the company’s CEO, Stephen Lake, told pv magazine. “All prices are before rebates, which can lower the final cost depending on location and eligibility. Jetson automatically applies eligible rebates and handles the paperwork on customers’ behalf, helping eligible homeowners save hundreds to thousands of dollars depending on their location.”
“The 50-gallon model has a UEF of 3.75, while the 65-gallon and 80-gallon versions achieve UEF ratings of 3.90 and 4.00, respectively,” Lake added.
The system uses R134a refrigerant and a vapor-compression heat pump mounted on top of the storage tank. A fan draws ambient air across a refrigerant-filled evaporator coil, where heat is absorbed and subsequently raised to a higher temperature by a compressor.
