How to keep your water heaters efficient

Since it’s always been part of your daily routine, it’s easy to forget about your water heater. Every day, hot water circulates in your house like the day before. However, as your water heater does its job, it also uses valuable energy.

Did you know that water heating accounts for a significant portion of the average home’s energy budget? With such a large room, you want to make sure your water heater is operating as efficiently as possible.

This article shares some tips on how to run your water heater as efficiently as possible and extend its life. Keep reading to learn more.

1. Install a high efficiency unit

Investing in a high-efficiency appliance is the most obvious way to improve water heater efficiency, whether you’re considering replacing your old water heater or looking for the best water heater for your new home.

Even if you follow all the maintenance routines for your existing unit, you cannot offset the high cost associated with an underperforming heater. Always look for the Energy Star label to ensure that the next unit you install in your home has a high performance rating. In general, these water heaters have an energy factor of up to 0.67 or more.

Fortunately, companies like Boutique Home Plans also provide information and specifications on choosing the right water heater for building a new home.

2. Consider a tankless water heater

If you are considering buying a new water heater, in addition to high efficiency, consider going for a tankless water heater.

In general, the tank of a water heater must be regularly flushed to prevent the accumulation of calcified sediments inside. Yet, you can avoid this problem by choosing a tankless water heater.

A tankless water heater only turns on when hot water passes through them, then turns off when you no longer need hot water. This makes the tankless water heater the most efficient type of water heater available on the market.

3. Turn down your thermostat

Most homeowners don’t realize this, but their water heater has a thermostat. This thermostat tells the heating system how much water it needs to heat in the tank. A hotter setting means the water heater takes longer to operate and requires more power to heat the water.

So, just like with your heating, ventilation, and air conditioning (HVAC) system, turning down the thermostat on your water heater can significantly reduce your energy bills. When you lower the temperature of your water heater, it’s estimated that you can save up to three to five percent on your water heating costs each year. That could equate to a significant sum of money – just to turn a knob.

In general, water heaters are preset between 130°F and 140°F. This temperature range is far too hot for human skin according to medical professionals. This is particularly harmful for young children as they may burn themselves. Experts recommend setting the thermostat to 120°F.

4. Check the sediment in your tank and drain regularly

As mentioned earlier, a common problem with tank water heaters is sediment buildup. So if you live in an area with hard water, the minerals in the water can impact the efficiency of your water heater.

When the water is heated, the minerals crystallize and settle to the bottom of your water heater. Day after day they build up and create sediment that reduces efficiency and slows down your water heater over time. The extra work eventually causes extra pressure in the tank, causing it to overheat and even rupture.

To remove the sediment, you need to drain your tank and rinse it with cold water. Experts recommend doing them at least once a year.

Flushing your water heater is a simple project that you can do yourself if you have the right tools. But before flushing your water heater, always consult your owner’s manual. In general, it is sufficient to disconnect the power source and close the water inlet valve. Then you need to attach a hose to the unit’s drain valve to drain the water outside your house or into a large bucket.

5. Use less hot water

One of the most obvious ways to improve the efficiency of your water heater is to use less hot water. Reduce hot water consumption, which means faster showers, fewer baths, cold water laundry loads, etc. are simple and effective solutions that can result in greater savings.

If you want to take it a step further, consider adding efficient and trendy faucet accessories and showerheads. Replacing your current plumbing fixtures with more water-efficient, low-flow alternatives can help reduce the amount of hot water you use.

6. Insulate the water heater tank and pipes

It’s easy for your water heater and pipe to lose heat, especially in the winter months. Don’t worry because it’s natural, but it also prevents your water heater from being energy efficient.

As the tank and pipes lose heat, the water heater must heat more water to compensate. The more water it heats, the stronger and longer it works. So the longer it runs, the more energy it consumes.

By insulating your water heater and the pipes that run through exposed areas of your home, you can prevent unnecessary heat loss and increase efficiency. An insulated tank and pipes can retain heat longer and increase water temperature on their own.

Pipe insulation is a relatively simple project once you’ve done your research and taken the right measurements. In general, you can find water heater insulation blanket kits on the market.


Inefficient water heaters don’t perform as well as they should and can cost you more. It’s a lose-lose situation. Fortunately, it’s fairly easy to improve the efficiency of your water heater. So be sure to follow the tips above to ensure your water heater performs as well as possible and avoid costly repairs to the unit. Note that the tips mentioned above will not only help you save on your electricity bills during the winter – they are also cost-effective and reliable measures you can take every day to ensure energy efficiency and performance. throughout the year.
