Building on their success with the Accelera 300, Stiebel Eltron's Accelera 300 E has an even higher Energy Star Energy Factor. The
Energy Factor is the ratio of useful energy output from the water heater to the total amount of energy delivered to the water heater and it is measured in accordance with strict standards so consumers can compare the efficiencies of one model to another. The Stiebel Eltron Accelera 300 E boasts an Energy Factor of 3.39, significantly higher than any other Energy Star rated heat pump water heater. The Accelera 300 E features an electonic display which provides each access to a wide variety of useful information, including total volume of hot water available. It has been fully redesigned from the ground up with a removable top for easy access servicing, and improved air intake and exhaust to allow for installation in compact spaces.

Heat pump water heaters are the latest water heating technology to emerge in the North American market. While heat pumps have been efficiently heating the air in our homes for decades, it is only recently that the same technology has been integrated into relative compact and highly efficient water heating systems for both residential and light commercial applications. The efficiency of a heat pump water heater typically exceeds 200%! Accordingly, they cost less than half as much to operate as a conventional tank-type water heater.
A heat pump does not generate heat like a conventional water heater. Rather, it "pumps" or transfers heat from one area to another by alternatively compressing and decompressing a refrigerant as it passes from one area to another. In the case of a heat pump water heater, it transfers heat from the air surrounding the heater into the water inside its tank. Since only a small compressor motor, pump, and fan are required, the process is extremely energy efficient!
The Accelera series heat pump water heaters feature an enamel-lined storage tank with a very high level of foam insulation for low stand-by heat loss. A back-up electric heating element is integrated into the unit to deliver extra heating power in the event that the heat pump is unable to draw sufficient heat from the air surrounding the unit to meet short-term peak water demands.

Important Heat Pump Installation Considerations:
The Accelera 300 E and other heat pump water heaters should not be installed in a location where the ambiant air temperature regularly drops below 42F (6C) or exceeds 108F (42C). Since the Accelera takes heat from the air around it, it is most desirable to install it in an area with excess heat such as a garage or attic in warm climate areas. In colder climates, the Accelera can be installed in a basement where it will help dehumidify the air. It is important to ensure that there is a sufficient volume of air around the unit for effective heat extraction and optimal efficiency. There should be approximately 800 cubic feet air in the installation room unless ducting is provided to bring in more air from another room or location and to exhaust the cool air from the outlet of the heat exchanger. Install in a location where there is a 2' gap between the air intake and any wall, and a 6' gap between the air exhaust and any wall.. When installing the water heater inside, the space where it is installed will generally be cooled down during the operation by 2 to 6F (1 to 3C). Please see the Installation manual for important recommendations regarding physical clearance recommendations.
To prevent nuisance from operating noise, never install the water heater in the vicinity of bedrooms. The compressor motor and fan make about as much noise as a refrigerator or small room air conditioner when running.
