Water heating accounts for up to 20% of the energy costs in a typical home. By finding ways to conserve water use and improve the efficiency of your hot water appliances and equipment, you can save substantially on your utility bills.
Conserving Water and Energy
- Fix leaking faucets. Repair leaky faucets quickly; a dripping faucet can waste gallons of water each day.
- Run a full load. You can conserve water and energy if you only operate dishwashers, clothes washers, and other appliances that use hot water when you have a full load.
- Take showers, not baths. Showers use less water than baths. Consider using a timer to encourage household members to take shorter showers.
- Install low-flow fixtures. You can purchase low-flow faucets and showerheads for less than $20 and achieve water savings of 25% to 60%.
- Lower the temperature of your hot water heater. The thermostat on your water heater should be set no higher than 120°F. For every 10°F that you lower your water temperature, you can save up to 5% on energy costs.
- Insulate your hot water tank. Insulate the hot water tank on older units, but be careful not to cover the thermostat or the burner on natural gas or oil-fired units. Newer, high-efficiency water heaters may not require insulation.
- Insulate pipes. Insulate the first six feet of the hot and cold water pipes connected to your water heater.
- Install a new, energy-efficient water heater. While energy-efficient water heaters may cost more than standard models, the energy savings over the lifetime of the appliance can be substantial. Use the yellow EnergyGuide label to estimate the annual operating cost.
- Energy-efficient appliances. Replace older dishwashers and clothes washers with new ENERGY STAR rated models. ENERGY STAR qualified appliances use less water and are more energy efficient than standard units.
- Drain water heat recovery. Up to 90% of the energy used to heat water in homes literally goes down the drain. By installing a drain water heat recovery system, you can use this energy to preheat cold water entering the water heater.
- Hot water on demand. Demand or tankless water heaters provide hot water as needed, without the standby losses associated storage water heaters. Demand units can be 8% to 34% more efficient than conventional storage tank water heaters, according to the U.S. Department of Energy, depending on the size of the home.
Solar Water Heating
Solar water heating is a cost-effective way to provide hot water for your home. Systems include storage tanks and solar collectors, which are typically mounted on the roof. Solar water heaters often require backup for cloudy days or periods of high demand. The backup is usually a conventional storage tank unit, which often comes as part of the solar water heating system installation. There are two basic types of solar water heating systems, active and passive. Active systems include a pump to circulate water throughout the house. Passive systems are less expensive, but not as efficient. However, they typically require less maintenance and may last longer. An ENERGY STAR qualified solar water can reduce your water heating costs by 50%.
