Potential Problems With Tankless Water Heaters And How To Fix Them

Posted on: 29 November 2019

Tankless water heaters are becoming a staple in many homes. They conserve energy by only producing heat for hot water on demand, rather than continuously heating water in a tank to make sure there is hot water when you want it. However, tankless water heaters are not without their problems. Here are a few potential problems you may encounter with these appliances and tankless water heater repairs can that fix these problems. 

The Heat Exchanger Is Not Working

The heat exchanger is a component inside the tankless heater that switches on to heat water when you open a hot water tap. It can be electrical coils, or it can be a gas-powered burner, depending on which model of tankless heater you have. If there is a power outage, you will have no hot water if your tankless heater relies on electricity, which is why a lot of homeowners choose the gas-powered version.

If you have electricity, but your electrical tankless heater is not producing heated water, it may be the heat exchanger's coils. If your natural gas or propane are working, but the tankless heater still produces no hot water, that too, could be the heat exchanger. Your plumber will have to open up the tankless heater and check the heat exchanger before diagnosing the problem and replacing this part. 


A tankless heater does not have a tank like traditional water heaters. Instead it does has plumbing entering the bottom of the heater and sending the water to be heated through the appliance. Then the heated water passes upward through the pipes that come out of the top of the appliance.

At any one of these junctions, the pipes can spring a leak. The pipes can also spring a leak inside the heater, which is not a good thing either. If you see water squirting, spraying, or dripping from pipes going into, coming out of, or coming from the bottom edge of the water heater, you have leaks in the plumbing connected to your tankless heater. The plumber will either have to tighten these pipes, or remove and replace them to stop the leaks. 

Electrical Problems

Even if you opt to use propane or natural gas to heat the water in your tankless water heater, you will still need electricity to power the heater. It cannot receive signals and operate as it should without some electricity. The plumber can check the wiring if the heater is only working sporadically.
