"I recently replaced my electrical storage water heater with an energy efficient ASUN Heat Pump Water Heater. The Heat Pump Water Heater draws heat from the surrounding air to heat the water. Now my kitchen area is cooler than normal. With the energy efficient setting, the unit only come on for about 20 mins a day, more than enough hot water for a family of 4. My water heating bill dropped by about 70 percent. Thank You ASUN!"
