Tankless Water Heater Maintenance

A water heater without a tank doesn’t mean it doesn’t have to be maintained. Tankless water heater maintenance is a must if you want it to last as long as it is supposed to.

Having hot water on demand means the heating elements are activated as water flows through them. There’s no tank to sit and build up heat. Still, even with no storage, there’s maintenance involved, especially if you want to get its useful life out of it.

Hard water is what will shorten the useful life of a Tankless water heater. Having it professionally maintained once per year will help keep it running smoothly. The minerals left behind from hard water are especially damaging to those coils that heat up the water.

We live in an area which has extremely hard water, if your house isn’t equipped with a water softener, you might even need your tankless water heater maintained twice per year. Descaling the heating elements can help it last longer.

Hard water isn’t the only issue that can affect the life span or efficiency of a tankless water heater, but the water temperature can as well. When the temperature is higher, the unit is more susceptible for scale buildup. Meaning that the hotter the water is, the quicker the buildup will happen. You’ll want to check and see how hot the water is.

Fill a cup with water and get a cooking thermometer and see what the temperature is. If it is reading higher than 120 degrees, then it’s too high. Having it higher than that is not only bad for your water heater, but is too hot and can cause scalding, and can also cause you to have higher utility bills too.
