water heater temperatureNew tenants moved into a house and were talking about how the water heater didn’t produce enough hot water. They said that the hot water stopped after only 10 minutes or so. There could me many factors here, so it was best to look at the water heater.

The water heater was only a few months old and was professionally installed. The chances that a dip tube was broken or other part was already bad were slim.  If the dip tube was broken, then incoming cold water wouldn’t be pushed to the burner to warm it up and you get lukewarm water after it mixes with the hot water already in the tank….but that wasn’t the problem. I looked for a large bathtub that maybe used all the hot water. Nope, they take showers. Then I considered the most obvious…the setting on the thermostat. It was set on its lowest setting. Duh!

I set the thermostat on the next setting up from the lowest and the burner fired up, just like it was supposed to. Once the water heater started heating the water to a higher temperature, the tenant used less of the available hot water and the problem was solved. I try to set the thermostat at the lowest possible setting to get the necessary amount of hot water, but no more. There is no need to waste energy.
