Navien Advantages

Navien BoilerNo matter which model you choose, you’ll enjoy these advantages:

  • Super condensing efficiency means every last ounce of heat makes it from the burner to the water you want to heat.
  • Takes ½” gas lines – same as your old water heater – no need to upgrade. Up to 24’ run.
  • High efficiency means less heat escapes through exhaust, and you can use 2” PVC pipe for venting (up to 60’ run).
  • Easy installation. It will probably take longer to remove your old boiler than to install a Navien.
  • Takes up less room. Wall mount installation means you reclaim space in your utility area.
  • Stainless steel heat exchanger resists corrosion.
  • Great water supply. Delivers 4.5 GPM @ 77 delta T for domestic hot water. That means it can simultaneously heat your home PLUS provide hot water to 2 showers and a dishwasher.
  • Eligible for energy efficiency rebates.
  • Safety features include leak prevention – no risk of flooding.
  • Great warranty:
    • 10 year warranty on heat exchanger
    • 1 year warranty on other components
    • 1 year labour.
    • Please note that the warranty is valid only when you purchase your Navien through a professional installer like Ottawa Home Services.
