How Often Do Tankless Water Heaters Need Maintenance

Tankless water heater maintenance is a must and should be done at least once a year. Also commonly referred to as an on-demand water heater, the tankless water heater may need maintenance every six months if your water heater is set to a high temperature or if you have hard water.

Investing in a tankless water heater is an excellent way to reduce related energy costs and enjoy the benefit of a steady supply of hot water on demand. However, as amazing as a tankless hot water heater can be for you and your family, you don’t want to overlook the importance of preventive maintenance

Over time, a tankless water heater can accumulate minerals that can build up on and erode the walls inside your tank’s heating chamber. To properly maintain and clean your tankless water heater, you must flush and remove the mineral deposits from your tank at least once per year

Flushing a tankless water heater on a regular basis could be the single most important task in keeping your unit running at peak performance. Failure to flush your tankless can result in a reduced service life and unnecessary fuel expenses. Although, we highly recommend having a professional check your unit annually, the flushing task is not too difficult and can save you money if you do it yourself.
