US-based Jetson Home has introduced a residential heat pump water heater with a uniform energy factor (UEF) of up to 4.0 and storage capacities ranging from 189 to 303 liters. The system features electric backup heating, integrated smart controls, and a claimed 75% reduction in energy consumption compared to conventional electric water heaters.
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. The heated refrigerant then circulates through a coil wrapped around the tank, transferring thermal energy to the stored water.
The company said the unit also provides some cooling and dehumidification of the surrounding space, with condensate discharged through a dedicated drain line.
The water heater incorporates two electric resistance heating elements that provide backup heating during periods of high hot water demand or when ambient temperatures fall below approximately 2.8 C. Under normal operating conditions, the heat pump provides water heating without assistance from the resistance elements.
The system stores water at 60 C and uses a thermostatic mixing valve to blend it with cold water before delivery at 48.9 C. According to Jetson, this configuration increases the amount of usable hot water available from each tank while limiting the risk of scalding.
The water heater connects via a wired connection to the company’s Jetson Hub controller, enabling performance monitoring, fault detection, and operating mode management. Users can adjust water temperatures, switch operating modes, and activate a vacation mode through the Jetson app. The control system is designed to prioritize heat pump operation and limit the use of electric resistance heating.
The unit is intended to replace conventional tank water heaters with a similar installation footprint. It requires a 240 V, 30 A electrical circuit, sufficient ambient airflow, a condensate drain, and clearance for servicing. Jetson said its installation crews handle the replacement process, including installation of the thermostatic mixing valve and an expansion tank.
Jetson Water can operate as a standalone appliance or as part of the company’s connected home energy platform. The manufacturer said installation typically takes a few hours.
Reservations for the new water heater will open on October 27, 2026, with installations scheduled to begin in 2027. The company said eligible rebates will be applied upfront and the product will be offered with 10-year coverage through its Jetson Care program.
