Winter Weather Wreaks Havoc on Water Heaters

Why do we experience more problems here in Indianapolis with hot water heaters in the winter than any other time throughout the year?

As the temperature outside gets colder, the water temperature also declines. This forces the water heater to work harder and longer to get the water to that temperature you like. It also causes more stress on the tank because the water enters the water heater on the top but is forced to the bottom through the dip tube, this means the top is hot and the bottom is colder which causes the tank to flex. In winter there is a greater temperature differential than in summer causing more more flexing.

Another stress caused by colder water is thermal expansion caused by the cold water being heated and expanding. As the water expands, it can create more pressure if there is no place for the water to go.

All of this extra flexing and pressure will cause a water heater that is at the end of it’s life cycle to give up resulting in a variety of problems such as a leaking tank to a pilot light that won’t stay lit.

Since we are smack-dab in the middle of winter, we wanted to recommend a few things that may help prolong the life of your water heater. One of the things you can do is to install a expansion tank for your water heater. An expansion tank absorbs the extra pressure caused by thermal expansion, reducing the stress on your water heater. Also, don’t forget to flush the tank to remove the sediment and replace the anode rod when needed. If you need any help with any water heater problems, repair or service, you know who to call!
