Why Buy a navien?Navien Tankless Water Heater

The Naviens we carry all come with these great features, no matter which model you buy:

  • No need to upgrade your gas line. Naviens use the same ½” gas lines that your existing water tank uses.
  • Condensing technology gives you maximum efficiency – waste heat is reclaimed and reused to heat water.
  • Because very little heat escapes the unit, conventional PVC pipe (2” diameter) can be used for venting (runs can be up to 60 feet).
  • Easy to install and service.
  • Mounts to a wall to take up less floor space in your basement or utility area.
  • Can be linked together to supply very large water demands.
  • Two stainless steel heat exchangers resist corrosion better than copper – and also resist hard water scale buildup better too.
  • Eligible for energy efficiency rebates – ask your Ottawa Home Services consultant which ones are on now.
  • Will not flood your basement – designed to completely shut off the water supply in the event of a problem.
  • Excellent warranty coverage:
    • 15 years on the heat exchanger
    • 5 years on other parts and components.
    • Please note that the warranty is only valid when you buy your Navien from a professional installer like Ottawa Home Services.

Technical Terms Used in the Chart Above

AFUE, or Annual Fuel Utilization Efficiency

This is the percentage of fuel that is converted to heat used to warm up your water. The highest numbers are better.

Flow Rate

How much hot water can be produced in gallons per minute and litres per minute. This will depend on the desired temperature.

NOx

This stands for two compounds: nitric oxide and nitrogen dioxide. While they are natural products of combustion, they must be safely vented. As they are also pollutants, Navien tries to keep NOx emissions to a minimum to comply with Canada’s reduction strategy. They are measured in PPM or parts per million.
