Tankless water heaters are a great appliance to have – you never have to worry about running out of hot water, a water heater using energy 24 hours a day, or even the standby losses that can occur when hot water sits in a 40- to 80-gallon tank all day. With a traditional storage tank water heater, you inevitably run into those issues related to everyday use, and you run the risk of the tank breaking and flooding your basement with several dozen gallons of water.
That said, tankless water heaters need repairs too. The gas line could have issues, the water inlets or outlets may get plugged, and you could even notice some minor leaks in the lines. These issues aren’t as stark as that of a storage tank water heater, but that doesn’t make them any less problematic.
What are the Common Tankless Water Heater Repairs?
Every tankless water heater is different, but they tend to experience the same issues no matter the manufacturer. These include:
– Scale buildup: When your tankless heater is constantly exposed to hard water, lime scale can build up on the internal system. This creates a layer of scale that impedes the heaters efficient operation.
– Exhaust venting problems: If your vent is improperly installed, this can cause the heater to breakdown.
– Internal corrosion: Gas-fired tankless heaters are vulnerable to burner corrosion if there isn’t a proper channel to vent the condensation.
– Freezing pipes: If you install an outdoor tankless heater in a cold climate, you need to properly insulate the water pipes so they don’t freeze during the winter.
– High water pressure: Too much water pressure isn’t a good thing; if the pressure gets too high for the heater to handle, it could break down.
What are the Common Fixes for These Problems?
Although there are a fair amount of issues that could arise with tankless water heaters, there’s little need to worry. Scale buildup can be fixed through annual cleaning; venting issues can be solved through ensuring the ventilation is properly set up. In the case of corrosion or high water pressure, you simply have to ensure the proper venting is installed and you have selected the right tankless water heater for your home’s pressure.
Realistically, it all comes down to needing to pay attention to your water heater and ensure it was installed right the first time. With regularly scheduled maintenance, you can even ensure that no issues befall your home.
