What Temperature Should You Set Your Water Heater To?

All homes have a water heater in them, or else you wouldn’t have any warm water running through your home. While most homeowners know how to properly care for their water heater and they know when it’s time to call a plumber for water heater repair, but they don’t know the proper temperature to set their water heater to. Some people set their water heater too high, while others keep the temperature too low. So, what’s the right temperature to set your water heater to? Today, we are going to find out thanks to Mr. Rooter Plumbing…

Water Heater Temperature

Our team of plumbers here at Mr. Rooter Plumbing often get asked what the perfect temperature is to set your water heater at. While the answer is simple, it does depend on your household. The normal setting when you get a new water heater installed is 140-degrees Fahrenheit, but this can vary depending on your home.

It was a late Saturday night. We had a super stubborn clog in some old galvanized pipes. Mr. Rooter send out Phil. Phil was great! He found the problem pretty quick.

Rose Bernard

Red Bank, NJ

We had a plumbing emergency and found Mr. Rooter while frantically searching for a 24-hour plumber. We feel like we hit a gold mine. Not only did we get a timely response. Everyone at Mr. Rooter was friendly, professional, competent and went above and beyond. Our plumber, Phil, was extremely helpful and gave us tips we could use moving firwars. Not to mention, the cost was extremely reasonable.

Joseph Chis

Hillsborough, NJ

Had sewer water backup in toilet and tub. Received callback as promised and arrived early. The tech determined we needed the main line to be cleared. He quickly located the opening and had us cleared in minutes. Very happy with the service. I was not prepared for the fee but it was an emergency.

Christopher Cox

Little Silver Township

Plumber, Phil, came out on short notice on a Saturday night and fixed our issue quickly, professionally and courteously. I contacted a different, well known plumbing company right before Mr. Rooter. The receptionist was rude and they didn’t call me back to say they couldn’t make it until after Phil left! The Mr. Rooter receptionist was very nice and they called me back quickly. I’m glad they did.

Rachel Turunen

Jackson Township

I was very happy that I went with Mr. Rooter’s. The service was very quick and up front. Jessie James was very helpful answering my questions and replacing my hot water heater. He was pleasurable to do business with. If another problem arises in my home, I will be using this company again.

William Holden

Brick Township, NJ

A thorough, professional, pleasant experience. I had a back-up in the 50 year-old pipes of my new home. I called Mr. Rooter to have them locate the blockage, snake the line, and then use their video snake to get a visual of the integrity of the pipes. I’m glad that I called and will use them again for future needs.

LarJ MarJ

Oakhurst, NJ

You get what you pay for. Edwin Robles of Central NJ educated me as a 1st time homebuyer on why and what he was repairing, prevention, PROMPT,(on a sunday at that!) clean, knowledgeable, super professional but DOWN TO EARTH and at a REASONABLE PRICE! Sewer pipes unclogged and main water line fixed. I was no longer crying once job was thoroughly executed. After all $#@* $tinks but somebody has to do it and I HIGHLY recommend him and this company for a job well done. THANK YOU VERY MUCH!!

Margie Rafferty-Criscione

Ocean Township

Absolutely lovely office staff! I always knew when the repair person was coming. Lorenzo our repair guy was awesome, I really don't think there is anything he can't do. He looks young, but don't let that fool you! So happy all the repairs are behind us. We really just did a one-stop shopping and decided to have everything we've put off fixed because it was such a tremendous experience!

What Temperature Should You Set Your Water Heater To?

While most water heaters come preset to a certain temperature, that doesn’t mean that’s the exact temperature it needs to stay at. Are you looking to make your home more eco-friendly and you want to reduce the energy you use each month? The way to do so is by lowering the temperature of your water heater. You can set your water heater to 120-degrees Fahrenheit to reduce your energy bill. By lowering your temperature to 120-degrees Fahrenheit, you can also avoid coming into contact with scalding hot water.

So, you’re probably at the point of wondering why water heaters are typically set at such a high temperature, right? There are many reasons why water heater manufacturers set your water heater to 140-degrees Fahrenheit. The first reason being that they aren’t conceed with the amount of energy you use each month. Those who are eco-friendly oftentimes do their own research, and when a plumber installs your water heater or provides you with water heater repair, they aren’t thinking about your energy consumption.

Another reason the temperatures are set so high is that the manufacturers want to avoid receiving complaints if possible. It’s a fact that no one likes to tu on the hot water and get cold water. When they set the temperature of your water heater to a higher temperature, the likelihood of you getting cold water is far less, meaning customers are happier. There are certain standards plumbers need to follow when providing water heater installation or water heater repair, so when the Mr. Rooter Plumbing team comes to your home, you can talk to them about the temperature your water heater is set at.
