Common Repair Issues with Tankless Water Heaters

Tankless water heaters make a great alternative to traditional water heaters, warming the water instantly as it passes through your pipes instead of being stored in a tank. That makes for a huge number of benefits to your Wyckoff, NJ home, including nearly instant heat, lower monthly costs and a theoretically endless supply of heated water for your use. But tankless water heaters run into problems just like any other appliance, and when they do, you need to move swiftly to get it fixed. Here’s a quick list of some common issues facing tankless water heaters, as well as ways for you to spot them.


Tankless water heaters don’t suffer from corrosion as often as tank models. But when condensation drips onto the burners, it can cause significant problems and may require you to replace the damaged component before the entire system shuts down.

Excessive Demand

One of the drawbacks to a tankless water heater system is that it can’t always meet high demand the way a tank system does. If it has to take on too much — with multiple outlets running at once — it may simply shut down, requiring a service call in order to return to regular use.

Venting Problems

Tankless water heaters used vents to get rid of heat and exhaust. When the vent is damaged or blocked, the heat can’t escape, which will damage key components in the system if you’re not careful. Most modern tankless systems have an automatic shut-off feature to turn the heater off before such damage occurs. But that still leaves you with the problem of fixing the vent before you’ll be able to effectively use your system again.

If you encounter any problem with your tankless water heater, turn it off and call the team at Design Air Inc. to get it fixed!
