Did you know there are things you can do that increase the energy efficiency of your water heater?
One of the easiest ways to check the temperature on your water heater's thermostat. The recommended temperature of hot water in the home is from 125 to 130 degrees which is comfortable for a shower and hot enough to wash dishes for most.
Temps below 120 however, can potentially cause bacteria growth. Most thermostats will have a mark indicating the best temperature setting for the unit.
Another way to reduce your energy bill is to use less hot water. An average shower is 8 min long and can use up to 17 gallons of water! Even with a large family, if each person in the house hold reduces their shower time just a few minutes less, it could have a big impact on the amount of hot water that is used overall.
A common way to save on your energy bill is by purchasing a high efficiency water heater with "high energy factors or EF - UEF" with an efficiency of 90-98%. Also, look for the "Energy Star blue label" (EF is 0.67 or higher).
Lastly, consider pipe insulation. Most water heaters are located in cold garages or unheated room such as a basement etc. This is why it is a good idea to insulate your water heater and or pipes to prevent heat loss and save you energy. Foam sleeves and water heater blankets like these will work well.
