5 Tips On Increasing Water Heater Efficiency


Just like your heating system, your water heater is an investment in your home’s comfort systems. When its performance suffers, your home comfort levels suffer. Lukewarm showers and low water pressure are things no homeowner wants to suffer through.

You know to replace your air filter and schedule routine maintenance to help your heater run at peak efficiency. But what can you do to help your water heater out? By following these 5 tips to boost your water heater’s efficiency, you’ll also reduce the need for repairs or water heater installation.

1. Insulate the Area and Wrap the Water Heater

Insulation plays an important role in your water heater’s efficiency. Although there’s a layer of insulation between the tank and the shell, it’s not perfect. Even the insulation of the room where the water heater is located can make a difference. If it’s in the basement or another drafty room, use a thermal gun to find air leaks occur and seal them.

You should also make sure your pipes and the water heater itself are well insulated. This will help maximize your water heater’s efficiency because you won’t need to run water for as long.

To wrap your water heater in insulation, There are water heater insulation blankets that can be wrapped around your water heater for an added layer of insulation. 

2. Reduce the Default Temperature

Your water heater needs to be set at a minimum of 120° F to prevent bacterial growth. Many homeowners set their water heater to 130° F. Try lowering the temperature by a couple of degrees and see how it goes. So long as it stays above 120°F, you can experiment with the setting to strike a balance between efficiency and comfort. 

3. Be Aware of Water Usage

Although we know Washingtonians tend to be conscious of their water usage, it never hurts to take a good look at how much water you’re using. Forego baths and opt for showers–short ones, ideally. Turn off the faucet when you’re brushing your teeth and shaving. Only run the dishwasher and clothes washer when you have full loads. If you’re concerned your water pressure is too high, let us advise you on the ideal water pressure for your home.

4. Repair Your Water Heater First

You can’t utilize all of these water heater efficiency tips until you’ve had repairs or maintenance. As long as you clear out sediment buildup and your heating element hasn’t rusted, you should be able to use these tips to full effect. Maintain, repair, and optimize, and you’ll never have to worry about spending too much on water heater bills again.

5. Schedule Water Heater Maintenance

Routine maintenance is the best way to get the most out of your water heater. During maintenance, the tank will be flushed to rid it of bothersome sediment buildup This sediment can reduce the efficiency of your water heater.

During maintenance, a plumbing technician will check the valves and connection points for corrosion or leaks, check your water pressure, inspect the anode rod, test the water temperature, and more.
