Enjoy the endless comfort of a Navien® tankless water heater

Endless hot water

Never run out of hot water again with a Navien® Tankless Water Heater.

Rather than constantly heating and maintaining a tank full of hot water in an old standard water heater, which comes with expensive gas bills due to inefficiency and standby losses, you can have endless hot water when you need it, for as long as you need it, with a Navien® tankless water heater. Most tankless water heaters have a life expectancy of about 20 years, much longer than any conventional tank-type water heater. Tankless water heaters are compact in size, taking up less space than conventional tank type water heaters. They also eliminate the risk of tank leaks and water damage to your home. 

We also offer maintenance servicing of your Navien® tankless water heater for $119.99, plus tax.

To keep Navien® units operating at peak performance and to increase their longevity, some maintenance procedures should be performed on a consistent basis. Below are steps we will take to make sure you are getting the most out of your Navien unit.

  • Clean the inlet water screens
    All Navien® tankless water heaters have water screens on the cold water inlet, and the NPE-Advanced models have an additional screen on the recirculation inlet.
  • Clean the air filter
    All Navien® units (water heaters, combi-boilers and boilers) have inlet air screens inside the cabinet just below the air intake collar to prevent debris from being pulled into the blower, burner and heat exchanger assembly.
  • Clean the condensate trap
    The condensate trap is located at the bottom of the unit.
  • Flush waterways
    Flushing is done using a pump to circulate a flush solution through the heat exchangers.
  • Verify operation

NOTE: The frequency of the maintenance will vary based on the installation, location, application, and operation of the unit, but it is advised to have your Navien® tankless water heater maintained annually.

How It Works

1.) When a hot water tap is opened, the tankless water heater detects water flow. 

2.) The igniter activates and the gas valve opens to supply gas.

3.) The burner ignites providing a flame to heat the water.

4.) The unit adjusts the flame to heat the water to your desired temperature setting. 

5.) The heated water is delivered to the faucet or appliance (washing machine, dishwasher).


Dual stainless heat exchangers last longer than copper.


Condensing technology reduces energy consumption and greenhouse gas emissions.


Protect the environment as you add value.

Navien® primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless water heaters to reduce energy consumption and CO₂ emissions. 

The ultimate in energy efficiency.

Navien® condensing technology provides up to 0.97 UEF /0.99 EF. These extremely efficient and eco-friendly units provide extra energy savings over traditional tank and non-condensing water heaters.
