    Where Technology Meets Ecology, Combination Boiler

    • The ideal solution for customers who need both domestic hot water and a space heating application.
    • Heats water when needed, making it environmentally sound as well as cost efficient.
  • Low NOx Emissions (≤ 20ppm)

    Hydronic Heating Benefits

    • Clean: little chance to cause dust 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.
  • Two Stainless Steel Heat Exchangers

    Extended Life, Stainless Steel Heat Exchanger

    • Integrated primary and secondary heat exchangers prevent corrosion.
    • Ensures a longer life expectancy over copper heat exchangers.
    • Stainless steel components maintain consistency, even during long period of use.
  • Better Adaptability to Gas System

    Eco-friendly, Premixed Burner

    • Modulates both 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.
  • Field Convertible

    Leak Detector

    • Prevents damages to water heaters as well as personal property.
  • Ultra Condensing Efficiency

    Automatic Water Filling System

    • Automatically fills water into space heating pipes when the unit senses a water shortage.
  • Ultra Condensing Efficiency

    Powerful Anti-Freeze Feature

    • The Combi’s built-in Control System is designed to keep the unit’s plumbing frost free in winter conditions.
