Tankless Water Heater Services in San Jose

Save Energy with a Tankless Water Heater in Silicon Valley and The South Bay

The primary advantage of a tankless system over a traditional water heater is the elimination of energy losses that come from keeping several gallons of water hot in a large storage tank. This results in tremendous energy savings, thus lowering monthly utility bills. In addition, tankless units generally require less maintenance and can last up to 20 years, which is about twice as long as conventional systems. Another great advantage is the space added back to your closet or garage when the storage tank is removed.

Our NATE Certified technicians are expertly trained to provide tankless water heater services in San Jose and surrounding areas.

How Tankless Water Heaters Work

When the hot water tap is turned on, the water flows into the system and is immediately heated by a gas burner or electric element. The hot water is then rapidly transferred to the faucet or showerhead. There’s no waiting for a storage tank to fill up and there is never a need to worry about running out of hot water.

Professional Installation of Tankless Water Heaters

It’s important that a tankless water heater is expertly installed. Proper installation is essential for getting the most out of a water heater and ensure proper functionality and also optimal energy efficiency and longevity.

There are several factors involved in ensuring a successful installation of a tankless water heater, including:

  • Sizing
  • Fuel type
  • Flow rate
  • Location
  • Safety issues
  • Building code requirements

Our experts have been installing tankless water heaters for years and can effectively complete this service and factoring in all these considerations. From helping our customers select the system that’s right for their needs and budget to performing a flawless installation, we’ll make sure the job is done correctly.

What Maintenance Is Required for a Tankless Water Heater?

Although tankless water heaters are known for their longevity, failure to maintain the unit can significantly decrease its lifespan. Just as faucets and showerheads collect lime scale over time, so does a tankless water heater. To avoid the destructive build-up of minerals, we recommend that every tankless water heater be flushed every six months to two years. The frequency depends primarily on the hardness of the water at the property. Without routine maintenance, a system can develop a clog that prevents normal heating activity. It can also cause the unit to overheat, which impacts its efficiency.
