What Is a Tankless Water Heater?

Tankless water heaters provide hot water to your home. In lieu of traditional tank systems that heat a reservoir of water for later use, tankless systems provide water on-demand. They utilize a heat-exchange system to heat running water through a coil (most commonly copper), that is then supplied to your home immediately.

Tankless systems, as the name suggests, do not hold any water internally other than what is currently running through the system as you use it. This system makes tankless heaters considerably more efficient, and is the secret to their growing popularity in the United States.

Tankless Water Heater Installation and Replacement

Replacement may not always be your first choice (though if your home still uses a traditional water heater, it may be a great idea!), but when it comes time to trade in your old system for a fresh one, HVAC Unlimited can provide you with the replacement you need!

Tankless Water Heater Repair and Maintenance

Tankless systems are phenomenal, and provide you with plenty of benefit. But, like any other machine or appliance, they need regular maintenance and the occasional repair. You may need repair for your tankless system if you experience the following:

  • Lukewarm or under-temp water. Your water heater has a simple job, and if your water isn’t hitting the temperatures you expect from it, there’s a good chance something has gone wrong. Be sure to check your settings (just in case!) before calling in a professional. If everything seems right, contact a pro for immediate repairs!
  • Leaks. A leak is a surefire sign that your water heater needs immediate service. This issue can very rapidly morph into a cascade of concerns, and should be addressed right away.
  • Problems with dishwashers and washing machines. These appliances rely on a certain temperature and pressure supply to work properly. If you’re having issues getting them to start up and perform, it may be a symptom of tankless heater failure.
