Possible Problems You Might Run into with a Tankless Water Heater

Plumbing tools

Do you have a tankless water heater in your home? Then you probably can’t imagine having to go back to the older style of water heater, thanks to all these fantastic advantages of a tankless system:

  • Unlimited hot water supply—the system is always ready to heat more
  • Lower energy bills
  • Compact size—80% smaller than tank water heaters—giving you more room
  • Reduced number of repair needs

But we’d like to focus on that last point. Your tankless water heater might run into malfunctions far less often than a storage tank system, but you can’t avoid all malfunctions. Below are some troubles that you may run into with your tankless water heater in the future—and what you can do about them.

The water isn’t getting hot enough

You turn on a tap and receive lukewarm water. You wait for it to get hotter, but it doesn’t. This lower temperature water may be a result of multiple taps being turned on at the same time. This is one of the few drawbacks of going tankless: the system can become overtaxed if there is too much demand placed on it from multiple taps and appliances simultaneously. If this problem happens often, you might consider installing a second tankless system. Many larger houses use more than one tankless water heater.

The water is getting too hot

Okay, what about the opposite problem? You certainly don’t want scalding hot water coming from your showerhead! If this happens, check the settings on the water heater; it’s possible they’ve been set too high. But this can also occur because the temperature sensor has broken. You’ll need to call water heater repair technicians to remedy this.

There’s no hot water at all

As soon as you discover no hot water at all coming from the taps, check on the power source for the water heater. The gas valve may be shut off. A circuit breaker could’ve tripped—and gas water heater does use electricity in order to operate. If you can’t trace the source, call for professional repairs right away; don’t make any attempt to repair the system yourself.
