Mississauga Home Comfort

NR-240A Tankless Water Heater

Features:

Ultra Condensing Efficiency

  • Boasts one of the industry’s highest ratings of 0.96 DOE energy factor.
  • Low annual operating costs and the best value and payback.

Extended Lifecycle

  • Dual stainless steel heat exchangers provide longer life expectancy and more resistance to erosion than copper heat exchangers used in other water heaters.

Navien Technology is Eco Friendly

  • The Eco Pre-mixed burner dramatically reduces NOx emission levels.
  • Boast the lowest emission levels in the industry.
  • Each Navien unit installed equates t0 31 cypress tress.

Inexpensive PVC venting solution

  • Lower exhaust temperatures allow for the use of 3” SCH 40 PVC venting.
  • Offers significant cost savings when compared with other venting materials.
  • Reduces installation time and makes it easy to run a 100 feet of venting.

Enhanced Safety with Dual Microprocessors

  • Two microprocessors offer better control and safe operation.
  • Not only control the burner for ideal combustion but also maintain the steady hot water temperature.

Optimal and Stable Combustion with APS and GPS

  • APS (Air Pressure Sensor) maximizes combustion efficiency by sensing and controlling the air required for optimal combustion.
  • GPS (Gas Pressure Sensor) offers stable combustion by sensing gas pressure and controlling the fan speed to maintain optimal combustion.

Leak Detector

  • Prevents damages to water heaters as well as personal property.

Space Saving Design

  • The wall mount design occupies approximately 80% less space than a traditional 50 gallon tank-type water heaters.

 

  • Eliminates minimum flow rate requirement with optional internal circulation mode.
  • Minimize hot/cold/hot stacking, the so called “Cold Water Sandwich.”
  • Saves water with the reduced time to get hot water.
  • Saves on installation costs with built-in circulation pump and buffer tank.
