The Navien NCB Combi-boiler is a tankless water heater-boiler that combines two bulky home appliances into one unit that occupies significantly less space, while providing access to more hot water, greater efficiency, cutting energy use and cost. Navien Combi-Boilers link well with air handlers, radiant floor, baseboard radiators, hydronic fan coils and hydronic heating.
Navien Combi-Boilers are the only tankless water heater that uses both a buffer tank and recirculation pump that recirculates colder water to be warmed up again before flowing through the taps, preventing the cold-water sandwich.
In addition to ensuring water temperature consistency, the Navien Combi-Boiler boasts many desired features:
80% less space than traditional boilers and water tank heaters
Stainless Steel lasts longer than fast corroding aluminum and copper.
Helps to reduce energy waste and excessive boiler cycling
NCB and NPE can be linked to supply an unlimited hot water supply
Works to provide heat to your hydronic radiator system and hot water for your taps
