Enjoying a hot shower after spending the day outside is one of winter’s greatest comforts. Yet when the faucet is turned as high as it can go and the water still doesn’t feel hot enough for your comfort, you may be dealing with the season’s effects on your hot water heater. There’s a way to resolve this problem, though. Here’s what you should know.

Should You Turn Up Your Hot Water Heater in the Winter?

Why Does Cold Weather Affect the Heater?

It all relates to the functionality of the hot water heater. As the unit works to heat up the water inside, cold water comes into the unit. That fresh water is even colder during winter because of reduced underground temperatures. So any cold water that settles in the tank as it’s trying to heat up your shower water instantly reduces the temperature, which affects your comfort. Old water heaters, in particular, have to work extra hard to maintain a comfortable temperature, and you may notice that your water is never quite as warm as you’d like as a result.

Should You Raise the Temperature?

The standard water heater is typically set to 120°. Higher temperatures may cause scalding. However, the water warms differently in the winter, and thus the unit might benefit by being turned up at least five degrees. If that doesn’t make a difference, a 10° thermostat increase may help. A plumbing service can adjust this for you if you aren’t comfortable handling your hot water heater.

How Can You Test the Performance?

It’s a good idea to test the effects of the temperature change before you adjust it again. After you’ve raised the temperature, turn on the tap in a faucet that’s furthest from the water heater. If it’s hot enough, then you can trust that it will do the trick. If not, try readjusting it again.

When Is It Too High?

You can only turn the thermostat up so high. If a slight increase isn’t effective, that’s typically indicative of a different problem with the water heater. Contact your plumbing service for an inspection. They can resolve issues such as buildup inside the tank, or determine if the unit is simply not operational anymore.
