Four Common Problems With Tankless Water Heaters


Tankless water heaters can be amazing additions to your home. Not only do they save on energy costs, but they also deliver a virtually limitless line of hot water for your entire house. No more cold showers after all the hot water has been used up, and no more waiting hours and hours on end for the hot water to arrive in the first place.

But tankless water heaters are not without their problems. While the maintenance may not be as frequent, every once in a while, you may need to call a technician to perform some tankless water heater repair. Below are some of the more common issues you may experience.

Sediment Buildup

It doesn't matter if you have a tankless or a traditional tank water heater, sediment buildup is a common problem with every water heater, especially those that are hooked up to hard water outlets. Soft water, by comparison, doesn't have very high mineral content, so it's much less likely to experience blockages over time. Hard water is exactly the opposite. It can produce a buildup that clogs your tankless water heater lines and decays your unit from the inside out. If that's the case, call a plumber to schedule a tankless water heater repair.

Bad Fuel Source

One day, you may turn on your faucet to find nothing but cold water coming out of it. If so, chances are there's a problem with your fuel source. Gas units are especially prone to this, as the gas can simply run out, but it could also be a problem with your electrical line (if you have an electric tankless water heater). Either way, once you fix the fuel source, your unit will be working again and the water should heat right up.

Blocked Exhaust

If your water heater's panel is telling you that it won't turn on because the exhaust is blocked, do a visual inspection to see what the problem could be. Tankless water heaters have vents on the side to let the hot air escape; if they're blocked, it could pose a fire hazard, so the unit will shut off to prevent overheating. Usually, the main culprit to this happening are things like bird's nests or a thick layer of dust. Clear the obstruction and try the unit again. If it fires, you're good to go. If not, call a plumber to come out and take a look.

how to prevent water lines from freezing

How many times have your pipes frozen this winter? Have you spent multiple days with your head under your cabinets holding a hair dryer on the lines drying to thaw the lines before they burst? If so, now is the time to begin making some changes. I worked with my plumber this year to make some adjustments to my home and my plumbing to avoid the taxing and stressful occurrence of frozen water lines. Visit my site to learn what course of action we took to prevent the water lines from freezing in my home even during the below zero temperatures we experienced.
