Water heating is the third largest energy expense in your home. It typically accounts for about 13% of your utility bill.
Here are Water Heating Tips:
- Install low-flow faucets and showerheads.
- Repair leaky faucets promptly; a leaky faucet wastes gallons of water in a short period of time.
- Lower the thermostat on your water heater; water heaters sometimes come from the factory with high temperature settings, but a setting of 120°F provides comfortable hot water for most uses.
- Take more showers than baths. Bathing uses the most hot water in the average household.
- If you are using an instantaneous water heater, switch it on before you shower and turn it off after use.
- If you are using a storage water heater, switch it on about 20 minutes before taking a bath, and switch it off after use. Leaving it on for too much time wastes energy.
- Insulate your electric hot-water storage tank, but be careful not to cover the thermostat. Follow the manufacturer’s recommendations.
- Insulate the first 6 feet of the hot and cold water pipes connected to the water heater.
- If you are in the market for a new dishwasher or clothes washer, consider buying an efficient, water-saving ENERGY STAR model to reduce hot water use.
- Install heat traps on the hot and cold pipes at the water heater to prevent heat loss. Some new water heaters have built-in heat traps.
- Drain a quart of water from your water tank every 3 months to remove residue that obstructs heat transfer and lowers the efficiency of your heater. The type of water tank you have determines the steps to take, so follow the manufacturer’s advice.
- Although most water heaters last 10–15 years, it’s best to start shopping for a new one if yours is more than 7 years old. Doing some research before your heater fails will enable you to select one that most appropriately meets your needs.
