Tankless water heaters have been around since the 1930s. However, their popularity and common household use did gain momentum in the U.S. until the 1990s. Also known as on-demand water heaters, these tankless versions heat water almost instantly as it flows through the cold-water line. Most units are the size of a small suitcase and promise to save you at least $100 a year on energy costs.
The list of advantages are long, but once you’ve made the investment in a tankless water heater, quarterly maintenance is needed to ensure its efficiency and long life. (For information on maintenance tips for storage tank water heaters, read our related blog.)
For all types of water heaters, the ideal thermostat temperature is 120 degrees. Lowering the temperature can save you money while also saving you from scalding water. Tankless water heaters typically have an LED panel on the device and/or point-of-use (POU) thermostats directly near the delivery point where you can adjust the temperature. Your owner manual will have instructions as needed.
Keep it clean
An on-demand water heater uses heating elements called heat exchangers. With tankless water heaters, minerals build up inside the heat exchanger, clogging the passages and slowing water flow. Failure to clean the heat exchanger can result in higher energy bills and a shortened lifespan of your appliance. This type of mineral buildup also can cause irreversible damage that most manufacturers don’t cover under warranty. In Colorado, our water tends to contain a higher mineral count, requiring more frequent cleaning. Quarterly cleanings are recommended.
In addition to cleaning and checking the combustion chamber, filters and heating element, Front Range HVAC’s tankless water heater maintenance includes a thorough check of safety switches.
