If you're considering a new water heater for your home, either because you're doing a renovation or new construction, there are several reasons to go tankless. For starters, tankless water heaters offer a seemingly endless supply of hot water right to your spout, without worrying about whether or not someone taking an extra long shower has used up all the hot water. It's also easier on your energy bills and lasts longer than traditional tank water heaters, which means you'll recoup the cost of the initial investment in no time.
But they're not without their faults. Many homeowners who have tankless water heaters rave about them, but even the most loyal machines have their quirks. Here are four of the most common issues with tankless water heaters and how to fix them. Most of them are able to be performed by the everyday homeowner, but if you're uncomfortable with any kind of troubleshooting, call someone who deals in tankless water heater repairs.
Though hot water heaters can deliver hot water anywhere in the house at any time, they're all limited in how much they can handle at one point in time. If you're running multiple appliances (dishwasher, washing machine) along with a couple baths and showers, it could strain the system so that it deteriorates quicker. You'll notice the water pressure goes down or the hot water isn't as strong, so to fix it, either stagger your usage or buy a second unit.
Hard water is the result of mineral buildup inside the water supply and affects nearly 85% of all homes in the United States. Over time, this mineral buildup can collect inside your tankless water heater and cause the system to break down. Invest in a water softener, or flush the system twice a year to remove the buildup.
Generally, if you're having a problem with the tankless unit itself, an error message will appear on the display screen to let you know what the problem is. Sometimes, the issue is as simple as debris that is blocking the vent ducts, such as bird nests or the occasional piece of flying garbage. Other times, you may have had a hose that was wiggled free, so reconnecting it will solve the problems. A visual inspection of your unit is usually enough to figure out the problem, but if you need extra assistance, schedule a plumber to perform a tankless water heater repair.Share
