  • NCB models allow for easy convertibility from NG to LP.
  • 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.
  • 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.
  • Automatically fills water into space heating pipes when the unit senses a water shortage.
  • The Combi's built-in Control System is designed to keep the unit's plumbing frost free in winter conditions.
