Tank-style water heaters are among the most energy-hungry appliances in the home, often second only to heating and cooling systems. By changing some habits and installing a few simple accessories, you can significantly reduce the energy consumption of your water heater. Here are some tips to help improve its performance:
Reduce Hot Water Usage at the Source
One of the easiest ways to cut hot water usage is to install water-saving showerheads. The maximum flow rate for a showerhead should be no more than 2.5 gallons per minute (gpm). Many water-conserving showerheads can reduce flow to as little as 1.6 gpm while maintaining acceptable water pressure. For a household of four, this could save up to 14,000 gallons of water a year, significantly reducing the energy required to heat the water.
Insulate the Hot Water Distribution System
Even in a small home, up to 10 percent of the energy used to heat water can be lost through the pipes that supply the hot water. Insulating hot water pipes is an inexpensive way to significantly reduce heat loss. This simple step can improve the efficiency of your water heater and ensure hot water is delivered more quickly to your faucets and showers.
Use a Water Heater Blanket
While many new water heaters have sufficient insulation built into the tank wall, older tanks may allow heat to escape. The larger the water heater, the more surface area there is for heat to escape. Prevent heat loss by wrapping your water heater tank in an insulation blanket available from most home supply stores. Some manufacturers recommend against installing insulating blankets on their energy-efficient models, so be sure to read your owner's manual before adding a blanket.
Perform Regular Water Heater Maintenance
Over time, storage tank water heaters can accumulate sediment, reducing heating efficiency. Flushing the tank annually will remove the sediment and make it easier for the burner or heating element to heat the water. Additionally, checking the anode rod and replacing it if necessary can help prevent tank corrosion and extend the life of your water heater.
Lower the Thermostat Setting
Many water heaters are set to 140 degrees Fahrenheit by default, but most households can more safely and comfortably use water heated to 120 degrees Fahrenheit. Lowering the thermostat setting not only reduces the risk of scalding but also cuts down on energy consumption and slows down mineral buildup in the tank.
Consider Upgrading to a More Efficient Model
If your water heater is over 10 years old, it might be time to consider replacing it with a more energy-efficient model. Tankless water heaters, for example, provide hot water on demand and can save a significant amount of energy compared to traditional tank-style water heaters. Look for models with the ENERGY STAR® label for the highest efficiency.
Install a Water Heater Timer
For households that use a water heater on a set schedule, installing a timer can help reduce energy consumption. A timer can turn the water heater off during periods of low demand, such as during the night or while you're at work, and turn it back on just before you need hot water.
