Lower Your Water Heater’s Temperature and Experience the Savings

Schedule Now

If you’re looking for low-cost methods to reduce energy bills, one of the best is to lower your water heater’s temperature. It costs nothing and you won’t feel the difference in temperature either.

Most households have no problems with the water heater temperature set at 120 degrees. The rare exceptions are people with compromised immune systems and those who don’t have heat boosting on their dishwasher. If your household doesn’t fit those two exceptions, save money and set your water heater thermostat down a few degrees.

Reducing the Water Heater’s Temperature

Lowering the temperature on the water heater isn’t difficult. You’ll need a couple of things: a thermometer to measure the water’s temperature and a marker. The thermometer gives you an accurate way to measure water temperature since, many times, the thermostat dials on water heaters can be inaccurate.

  • Take the water’s initial temperature at the faucet furthest from the water heater. Turn on the hot water and let it run a couple of minutes, then measure the temperature.
  • On the water heater’s thermostat, mark the current location.
  • Turn the water heater temperature down.
  • Wait two hours and take a new temperature reading at the furthest faucet.
  • Repeat until you reach the 120-degree mark.
  • Mark the 120-degree mark on the thermostat.

Benefits of Lowering Water Heater’s Temperature

Bringing down the water heater’s temperature saves money in two ways. It reduces the amount of water needed, as well as the amount of energy needed to keep the water at a certain temperature.

Besides lowering your energy costs, turning down the temperature of your water heater also prevents scalding and slows mineral buildup and corrosion, prolonging the water heater’s life.

If you lower your water heater’s temperature, you should start seeing lower energy bills immediately. For more information on maintaining, repairing or replacing your water heater, contact the pros at Apollo Home Heating, Cooling and Plumbing. We serve communities in the greater Cincinnati area.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
