Rheem. An expanded line of heat pump water heaters now includes a 40-gallon model designed for smaller households with a lower hot-water demand. The HP-40 hybrid meets Energy Star requirements and offers an energy factor of 2.0, more than twice the energy efficiency of a standard storage water heater, the maker says. The unit will also be eligible for federal tax credits, as well as some state and local utility incentives and rebates. The 40-gallon HP-40 measures 21 inches in diameter, but weighs 10 pounds ligher and is 10 inches shorter than the original model, with an overall height of 65 1/2 inches. Three modes of operation include heat pump only, heat pump/electric elements, and electric heat only, to meet various hot water needs. www.rheemhpwh.com. —L.H.
