Tankless Water Heater Not Working Right? We Can Help!

Although the storage tank water heater is the most common way for homes to receive the hot water necessary for daily chores, the tankless water heater is gaining rapidly in popularity. If you have a tankless water heater, than you probably can’t imagine switching back to using an old tank model. After all, a tankless water heater uses much less energy, it never runs out of its hot water supply, it takes up 80% less space, and it lasts for many years longer with far fewer repairs than a standard water heater.

But repairs may still be necessary!

Sorry to be the bearers of realistic news, but that tankless water heater that you and your household depend on isn’t invulnerable. At times you might notice subpar performance from it—or even a complete failure to provide any hot water at all. You can always contact our water heater professionals for water heater repairs when you need help. We’ve written a guide to troubleshooting some of the more common problems from tankless water heaters:

  • Zero hot water: The first thing to check is the circuit breakers to see if any have tripped. Even gas-powered water heaters use electrical power, and the demand can trip a breaker. Check on the control panel for the system to find an error code, which you can use when contacting repair professionals.
  • Lukewarm water: The water not getting hot enough? There are a few possibilities to look into. One is that multiple taps are on at the same time, which can place too much strain on the heat exchanger of the water heater. If this is a regular occurrence, you might wish to have a second tankless water heater installed, which is common for larger homes. The problem may also be coming from sediment blocking the heat exchanger; you’ll need repair technicians to remedy this.
  • Scalding hot water: What if the water is too hot? This often occurs because the system controls are set too high. But it could also be a broken temperature sensor, and that needs expert repair attention.
  • Low water pressure: The tricky thing about this occurrence is that it can come from sources other than the water heater, such as a problem with the utility company or leaks in your pipes. This could also be too many taps on at once. If the problem persists for a few hours, it’s time to call us to analyze what’s happening.
