4 Tips To Save On Hot Water
Tank storage water heaters are one of the most energy intensive appliances in the home, second only to heating and cooling systems. By changing some habits and installing a few simple accessories, you can reduce energy consumption from your hot water heater significantly.1. Reduce hot water use at the source
. One of easiest ways to cut hot water usage is to install water saving shower heads. The minimum flow rate on a shower head should be no more than 2.5 gallons per minute (gpm). Many water conserving shower heads can reduce flow to as little as 1.6 gpm while maintaining acceptable water pressure. The water savings for a household of four could be as much as 14,000 gallons a year along with greatly reduced energy required to heat the water.2. Insulate the hot water distribution system
. Even in a small home, as much as 10 percent of the energy used to heat water can be lost in the pipes that supply the hot water. Insulating hot water pipes is an inexpensive way to significantly reduce heat loss.3. Use a water heater blanket.
While many new water heaters have sufficient insulation built into the tank wall, many older tanks will allow heat to escape. The larger the water heater, the more surface area that will allow 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.4. Water heater maintenance.
Over time, storage tank water heaters can accumulate sediment that reducing heating efficiency. Flushing the tank annually will remove the sediment and make it easer for the burner or heating element to heat the water.
