Water heaters

When it comes to water heating, natural gas is best because they are usually less expensive to operate than electric models.

 

 

 

Tips

  • Install heat traps on both the cold and hot water intakes of your hot water heater.
  • Install an insulation jacket on an existing electric water heater to greatly reduce heat loss (We don’t recommend insulation jackets for gas water heaters). Some manufacturers recommend against installing jackets on their energy-efficient models, so make sure to follow the manufacturer’s installation instructions.
  • Insulate both cold and hot water pipes coming off of the water heater.
  • After disconnecting the power supply at the breaker box, lower the thermostat of the water heater to 125˚F for safety and efficiency. For every 10 degrees you lower the water heater temperature, you could save up to 3% in heating costs.
  • For homes built prior to 1992, we recommend installing low-flow showerheads and faucet aerators to save energy and water.

 

Go to:
Location

The water heater should be located outside the conditioned space, in an attic or garage. Water heaters can also be installed in a sealed mechanical room inside the home with combustion air provided by a ducted opening to the outside. The door should be weather-stripped, as if it were an exterior door. The walls and floor of the mechanical room should also be insulated.

 

Replacement

Water heaters typically last 10-15 years. If your water heater is more than 15 years old, we recommend replacing it before it breaks down. Also replace your water heater if it’s leaking.

Replacement water heaters don’t necessarily have to be the same size as your previous model. If you have incorporated water-saving devices into your home — such as low-flow showerheads and/or faucet aerators — you may even be able to reduce the capacity of your water heater. Be sure to follow the manufacturer’s recommendations on proper sizing.

Generally, the smaller the water heater the more energy efficient, because the smaller tank has less heat loss. 

Installation
  • Follow local codes, manufacturer’s guidelines and use good judgment.
  • Elevate the water heater approximately 18 inches above the ground.
  • Keep combustion materials away from gas water heaters.

 

Maintenance

Anode rods (heating elements) within the water should be checked at least once every 3-4 years. Excessive build up of sediment will shorten the life of the tank, decrease energy efficiency and cause noise. Flushing out the sediment in a water heater at least once a year is a good idea, but be sure to follow the manufacturer’s guidelines.
