Rheem Water Heating has expanded its line of hybrid heat pump water heaters with a new 40-gallon model designed for smaller households with a lower hot-water demand. The new Rheem HP-40 hybrid meets ENERGY STAR® requirements; certification is pending. The unit will be available in early June. Like the 50-gallon model unveiled in 2009, the new HP-40 hybrid offers an Energy Factor (EF) of 2.0, or more than twice the energy efficiency of a standard electric storage water heater.
