Stiebel Releases Accelera 300 Heat Pump Water Heater

Stiebel Eltron’s Accelera® 300 heat pump draws only 500 watts and can be tied into a photovoltaic (PV) system.

With the backup element (+1,700 watts) you may need grid-tie, but with the full tank (80 gallons) at 140°F and 76.2-gallon first-hour rating (2.73 EF), daily hot water needs may be satisfied without the backup element.

The Accelera 300 boasts a 10-year warranty and is Energy Star® certified. Annual energy usage is just 1,391 kilowatt-hours per year—at 12 cents per kilowatt-hour, that’s only $167 a year.
