  • Where Technology Meets Ecology, Combination Water Heater

    Navien’s Condensing Combi Gas Boiler/Water Heaters are the ideal solution for customers who need both domestic hot water and a space heating application. Unlike conventional boilers, Navien’s Combi Gas Boiler/Water Haters heat water only when needed, making it environmentally sound as well as cost efficient.

  • Hydronic Heating Benefits
    • Clean : Little chance to cause or lower humidity because there is no air movement.
    • Silent : Offers silent heating because no blowers are needed for forced circulation.
    • Comfort : Keeps floors warm but indoor air fresh, making people feel warm and comfortable.
    • Coverage : Radiant heat makes heating from floor to ceiling possible.
    • Economical : Radiant heat in the floors can transmit warmth throughout the house hours after turning off
      the heater.
  • Extended Life, Stainless Steel Heat Exchanger

    Stainless steel for the Combi’s integrated primary and secondary heat exchangers prevents corrosion and ensures a longer lifespan over copper heat exchangers. Stainless steel components also maintain consistency, even during long periods of use, and aid in efficiency by caputuring as much condensation as possible.

  • Eco-friendly, Premixed Burner

    High grade stainless steel burner uses pre-mixed air and gas ratio providing a 10% to 100% firing rate. The Eco-Pre mixed Burner generates at least 20% less CO2 and about 75% less harmful air pollutants such as NOX than other conventional water heaters.

  • Advanced Safety Operation, Gas-Air Ratio Control

    Navien’s Gas-Air Ratio Control(GARC) System highly advance control system modulates both the air and gas ratios required for optimal combustion. The ingenious built-in CO monitoring system will shut the Combi unit down in the event of excessive CO gases build up that can cause a hazardous condition.

  • Auto Sensing & Adaptive Heating, ASA Control System

    The Combi’s ASA Control System maintains a consistent, comfortable temperature throughout the home at all times even taking into account the home’s design and outside temperature.
    The secret to system involves a built-in thermostat which senses even the slightest temperature changes. The Combi’s space – heating application calculates the amount of heat required based on the difference between the return-water temperature and the indoor temperature, then automatically adjusts and controls the temperature accordingly.

  • Weather Compensation Heating, K-Factor Heating

    An outdoor sensor can be connected to Navien’s Condensing Combi Water Heater. With this device the unit can automatically regulate the heating temperature according to changes in the temperature outdoors, allowing for precise indoor heat regardless of the weather
