Water Heater Energy Efficiency

water heater energy efficiency You use your water heater every day which means that making sure it is as efficient as possible can save you a lot of money on your utility bills. Between showering, doing laundry, and washing dishes your water heater has to heat a whole lot of water. According to the US Department of Energy, your water heater uses 18% of the total energy your home uses. With our helpful tips you can bring that number down, save money, and conserve water and we’re sure if you’ve found your way here you’re looking to do all three.

The two easiest ways to reduce energy usage that your spending on hot water is to reduce how much hot water you’re using in the first place and reduce heat loss. These aren’t hard to do, but we’ll walk you through them so you can make sure that your efforts have the most impact.

How to Use Less Hot Water

  • Replace wasteful shower heads with modern low flow fixtures. New low flow fixtures use as little water as 1.6 gallons per minute while still delivering water at 80 PSI.
  • Find and repair leaks in your home.
  • Replace the aerators on your faucets with new ones that have flow rates of less than one gallon per minute.
  • Use cold water to wash laundry.
  • Don’t wash dishes by hand. Modern dishwashers use as little as 3 gallons per load which is over 20 gallons less than washing the same amount of dishes by hand.

How to Reduce Heat Loss from your Water Heater

  • Give your tank a blanket – If you’re water heater is a conventional model with a tank, investing in a water heater blanket can go a long way to reducing heat loss
  • Insulate your hot water pipes – You can pick up inexpensive pipe insulation from your local hardware store and it will go a long way to reducing heat loss as water travels through your pipes.
  • Turn down the temperature on your water heater – Reducing your water heater temperature from 140 degrees F to 120 degrees F can reduce your energy usage by 6-10 percent

Taking these steps will go a long way to reducing your energy usage and save you money. If you are still using a conventional water heater with a tank we recommend switching to a tankless water heater as these are far more efficient than traditional tanked models. If you are considering replacing an old water heater with a modern or energy star rated model make sure to enlist the help of a professional. A new water heater is a major investment in your home and if it is installed improperly the unit could be damaged.
