Signs Your Tankless Water Heater Needs Repairs

As the name suggests, tankless water heaters do not require storage. They heat water based on demand, making them more energy efficient because there is no energy loss brought about by heating water that ends up being unused. You also don’t have to worry about running out of hot water because they heat the amount of water you need for the occasion. Just like any other appliance, tankless water heaters can be prone to issues and may require repairs. Here are some signs that your tankless water heater might need repairs:

  • Drop in hot water pressure, caused by build-up in intake and outtake lines
  • Water dispensed is no longer as hot as desired, probably due to an issue with the gas burner 
  • Shuts off on its own, caused by clogged water filters that safety devices mistake as overheating
  • Other appliances connected to the tankless water heater are malfunctioning
  • Leaks from any plumbing appliance is always a bad sign, probably caused by broken or loose valves 

You need to address these issues with the help of a skilled plumber from Precision Air & Plumbing. Contact us today if you are looking for convenient and impressive repair for your tankless water heater. Work with us, and we will fix any issues with your plumbing appliance so you can get back to using it for your daily needs.

I wanted to make sure my air conditioner was ready for summer. Fernando came out and made sure my unit was tip top. He was friendly, professional and not a sales man. Thanks Fernando!
