Tankless Water Heaters Need Repair Too


Tankless water heaters tend to work very well and keep the people who use them very happy. So happy, in fact, that it might be easy to forget that the tankless system is even there. (If you never have to wait for a tank to refill and heat back up before you can take your shower, do you ever think about your water heater at all?)

But tankless water heaters are complex systems, and just like any other appliance, they can struggle or even break down. Here are some signs to keep an eye out for. If you notice any of these things, it’s time for water heater repair.


Tank or standby water heater systems are much more likely to leak than tankless models. However, because water flows through them, leaks are still possible. If you notice water pooling below your tankless system, you should reach out for expert plumbing assistance. It may be something as simple as a valve being loose. Keep in mind, though, no matter how easy a fix may seem, it’s critical to have your water heater repaired by a qualified professional. Gas-burning appliances must, by law, be installed, maintained, and repaired by plumbers with the proper certification. And amateur repairs can void your warranty. 

Low Water Pressure

Either a gradual decrease or sudden drop in water pressure is always a good reason to call a plumber. When it’s your hot water specifically, the problem is probably located at the water heater. Because the lines carrying the hot water are already fairly narrow, any mineral buildup that makes even less space for the water to pass through can have a very noticeable effect.

Low Water Temperature

It’s understandable to want to crank up the temperature on the aquastat (the water heater equivalent of a thermostat) when you notice that your water temperature never gets more than lukewarm. But don’t do it! You could end up scalding yourself or a family member. If your water heater was doing the job just fine and isn’t managing it anymore, it’s time for repairs. The drop in temperature might mean trouble with the burners, but it could also be from sediment or corrosion.

The System Shutting Off

Most heating appliances have emergency shut-off capabilities which prevent them from overheating and potentially starting a fire. This is for your safety. If your water heater keeps shutting off, and you have a whole-house water filter, check that first to see if it needs to be changed. If not, or if changing it doesn’t fix the problem, get repairs.

Other Appliance Trouble

Your water heater supplies hot water to your dishwasher, washing machine, and possibly more. If you notice strange behavior from one of those appliances, the true culprit may be the water heater. 

Prompt water heater repair in New Haven, CT could be the difference between a quick fix and a complete system failure, and you don’t want to have to replace your water heater.
