Did you know that your hot water tank is the second largest energy user in your home? That’s right! Only your heating and air-conditioning system uses more. Hard water scale can coat the inside of a water heater and drastically reduce its heating efficiency. Greater fuel consumption and higher utility bills are a result when the appliance has to heat water through a layer of rock. According to a study commissioned by the Water Quality Research Council and conducted at New Mexico State University, water heaters work 22-30 percent less efficiently with hard water, driving up utility bills unnecessarily. With soft water, you’ll not only protect your hot water tank and make it last longer, but you’ll also save money on your energy bill.
