How To Adjust Your Hot Water Temperature

Tap water can be dangerous. Even though your water heater is hidden away, it plays an important part in the plumbing of your home. Many people, mostly children end up visiting hospitals each year with burns caused by water heaters that are set too high.

A poorly functioning water heater could result in bigger electricity bills as well as water that is either too hot or cold. It is important to conduct annual maintenance to ensure that your unit is clean (hard water build-up is damaging to your water heater) and is set to the right temperature. You’ll save more than money, but also prolong the life of your water heater and have a healthy and happy family too. We have these tips for you to follow. 

1. What is the right temperature?

Professionals recommend keeping your water heater set to at least 50C/120F and ideally 55C/130F and 60C/140F. Any higher, or lower, could actually be dangerous. Too hot can result in a nasty burn, in colder water temperatures, bacteria can form in the water heater tank. This could become a health risk for you and your family, potentially exposing you to health hazards such as Legionnaires’ disease, which thrives at 77 degrees and 113 degrees Fahrenheit.

2. How to check your temperature setting?

If you are concerned that your water heater is set at an incorrect temperature — either too high or too low — call in a plumber who will be able to easily check the setting with a special thermometer and make adjustments as necessary.

If the temperature has been adjusted on the water tank, but you do not seem to be noticing any difference in water temperature, a professional will also be able to check for issues like sediment buildup or calcification in the tank. Another indication that sediment may have built up in the tank is if you hear hissing or sizzling noises.

A professional can drain the tank and might be able to fix the problem without a tank replacement.

3. What is the life expectancy of your water heater?

Hot water heaters typically last anywhere from 8 to 12 years. If you have a water heater that is 10 years or older and appears to be leaking or is having some issues working, you might want to consider replacing it altogether rather than just making a repair that will only temporarily solve the problem. Newer heaters are more efficient and thus cost less to operate. 

4. Maintenance 

Some TLC, upkeep and maintenance can help extend the life of your water heater and keep it in good working order. You may want to consider doing this maintenance with a professional in order to keep your water heater working properly.

Definitely keep your water heater set between the optimal temperatures. This will prevent any bacteria from forming in the cold water and prevent scalding you with a hotter-than-expected shower and possibly a trip to the doctor too.
