Did you know water heating is the second largest energy expense in any given home, approximately 13%?

Four ways to reduce your water heating bill:

  1. Use less (hot) water
  2. Lower the temperature of your water by reducing the thermostat on your water heater.
  3. Improve the water heater’s efficiency by insulating it and the pipes.
  4. Buy a more efficient model, generally a new model.

If your hot water tank is warm when you touch it, you can save 7-16% annually in water heating costs simply by insulating the tank. Follow the manufacturer’s instructions/recommendations. Insulating the pipes can have a similar, yet smaller effect, saving approximately 3-4% annually. A general accepted set temperature is 120F. If your hot water heater does not have built-in heat traps, install them manually to prevent heat loss. Consider installing a temperature sensitive switch that turns of the water heater when it’s hot enough.


Did you know sediment builds up within your water tank? The sediment makes your hot water heater less efficient. Thus, you should drain a quart of water from your water tank every 3 months to remove sediment build-up, by following manufacturer’s instructions of course.


Consider installing a drain-water waste heat recovery system. The brilliance in this idea is conserving energy by transferring the heat from kitchen and bathroom waste water (think doing dishes and taking hot showers) to preheat the cold water entering the water heater or other plumbing fixtures.


Install aerating, low-flow faucets and showerheads. If you have to wait for your shower’s water to warm up, consider a showerhead.


Repair leaky faucets promptly. Leaks are a surefire way to waste gallons of water in short periods of time. One drip per second wastes 1661 gallons of water per year, over $35 per year.


When you buy new appliances, such as a dishwasher or clothes washer, buy an ENERGY STAR model to increase efficiency and save hot water. Visit to see the recommended appliances.


Replacing your water heater with a brand new one may cost more initially, compared to repairing an old model. But consider that the energy savings will last the life of the appliance, typically 10-15 years. If your water heater is more than 7 years old, we suggest you prepare your budget and mindset for purchasing a new ENERGY STAR appliance when the time comes. You can find the ENERGY STAR label on several types of water heaters: heat pump, high efficiency gas storage, gas tankless, and solar. Conventional storage water heaters are the most popular system for home use. Potential fuel sources are natural gas, propane, fuel oil, and electricity. Tankless water heaters (gas) work without a storage tank, as the name suggests, and heat water directly. Tankless water heaters can save about 30% compared to standard gas storage tank water heaters, but come along with a downside. That downside is that if multiple locations require hot water simultaneously, you may need two or more tankless water heaters to supply the demand. We recommend you contact your local Plumbers in Rochester, MN if tankless installation is the direction you want to go.


Heat pump water heaters can be a good option for those in moderate to warm climates, and can provide dehumidification in the summer. Solar water heaters are a potential option if you heat water with electricity and have an unshaded, south-facing location. There is even a decreasing federal tax credit through 2021 for solar water heater use.
