A family of four uses about 700 gallons of hot water a week. If you use less hot water, you’ll save energy and money.
Lower your expectations
The U.S. Environmental Protection Agency (EPA) estimates that low flow shower heads and faucet aerators can reduce hot water consumption by 25 to 60 per cent saving about $200 off of your household water bill.
Use the economy setting on your dishwasher, and forget about pre-washing. Good dishwashers can beat the leftovers from a dirty dish. Simply scrape your dishes and load.
For every 10 degrees you turn down your hot water heater, you’ll save 3 to 5 per cent on your bill. Keep the temperature between 120 and 140 degrees but no cooler. You don’t want bacteria to grown inside the tank! If the thermostat on your water heater doesn’t have a numbered gauge, set it midway between low and medium and adjust until you reach your target.
Keep it clean.
Hot water tanks naturally build up sediment, making it inefficient and harder to save energy. Drain a quart of water from your tank every three months to remove sediment that impedes heat transfer and lowers the efficiency of your heater.
