A tankless water heater is a great investment in your home's plumbing system. You can have unlimited hot water and lower energy bills. You will also have fewer repairs with a tankless water heater as opposed to a traditional model. However, tankless water heaters can have some issues at some point over time. There are few things more frustrating than not having hot water when you need it. The following are some examples of the more common issues you may experience with your tankless water heater.
You May Experience Low Water Pressure
The tankless water heating system moves water to a heat exchanger from the hot water line. The water heats up in the heat exchanger powered by gas. Over time, water deposits can build up inside the heat exchanger and can clog the outlets that allow the water to flow into your plumbing system. This results in low water pressure from your hot water faucets. Hard water is typically the culprit of the clogs. Your plumber or HVAC technician can clear the clogs and install a water softener to prevent the issue from happening again.
You May Have Corrosion in Your Heat Exchanger
Over time, the heat exchanger may develop leaks. When you have a leak, the water that gets outside the exchanger can pool up and eventually cause corrosion. When a tankless water heater corrodes, you may have to replace the entire system. You may also experience corrosion when the water heater does not vent properly. Not only can it damage the water heater, but it can cause dangerous gas to leak inside your home. If you notice any sort of corrosion, you should call your HVAC contractor or plumber right away.
You May Have Issues with the Gas Ignition
Just like any furnace operated by gas, it can have issues with the power system. Over time, the gas jets can get dirty. When this happens, the heater cannot ignite completely. The dirty system may even fail to light at all. When the heat cannot ignite, you will not have any hot water until you clean the components.
If your tankless water heater begins to have problems heating your water, you need to call a professional right away. It is crucial to get to the bottom of any issue with the heater so you are not without hot water in your home. You should work with a professional, like Edelman Inc, who has experience in tankless water heaters and gas systems.
