This model supports both natural gas and propane up to 10,100 ft. elevation and allows for flexible configurations, with cascading up to 15 units and common venting for up to 7. With built-in 3-zone pumps and extended venting options, it’s a top choice for comfort and convenience in any home.
What is a combi-boiler?
A combi (combination) boiler is designed to heat a building, using hot water (similar to a boiler), but also includes the components and controls to internally heat the domestic hot water (DHW) required in the application. By having both heating and hot water in one unit, the combi will save space in the mechanical room and also save on the initial installation compared to separate appliances.
