A tankless water heater is a worthwhile investment for your home or business. Unlike conventional tank-style water heaters which continuously heat stored water to a set temperature, tankless units heat water only when it’s needed. Tankless water heaters are energy-efficient, take up less space, and offer a continuous supply of hot water. So it’s easy to see why they are gaining tremendous popularity in many homes and businesses. Of course, no plumbing fixture is without problems, including tankless water heaters.
Let’s look at the common tankless water heater problems you may encounter and how to deal with them.
Water Is Too Hot
A tankless water heater can overheat just like a tank-style unit. This problem can be caused by a number of things.
Gas-powered tankless water heaters have a hot surface ignition system that ignites propane or natural gas. Just like other components of the heater, the hot surface ignition system can malfunction and lead to heating problems.
Every tankless water heater has a flow rate capacity that you shouldn't exceed, otherwise, you could overload the system and it will shut down. For instance, running multiple showers and hot water faucets at once, your tankless unit may not produce enough hot water. If your tankless water heater becomes overloaded frequently, you should consider installing a new water heater with a higher capacity.
Mineral or sediment buildup is not unique to tank-style heaters, but it also affects tankless water heaters. If you have hard water in your home, you need to keep an eye out for mineral buildup inside your water heater. Over time, minerals such as calcium and magnesium may slowly start to collect on the interior parts of your water heater and cause water discoloration and smelly water. It’s advisable to flush your water heater regularly to get rid of the mineral buildup.
Your tankless water heater may fail to produce hot water due to too many appliances running at once, a tripped breaker, your gas or electricity isn’t on, or ignition failure. If you experience this problem, call reliable water heater installers to inspect your unit and make repairs.
