CX Combi Boiler
The IBC CX Combi is a wall-hung, gas-fired condensing combination boiler, offered as the CX 150 and CX 199. It handles both space heating and domestic hot water from a single cabinet, reaches 95% AFUE, and modulates 10:1 so its output tracks the actual load instead of cycling hard on and off.
One wall-hung unit, two jobs
As a combination boiler the CX supplies hot water to the taps on demand through a brazed-plate heat exchanger, as well as heat to the hydronic loop — so there is no separate tank to install or maintain. Full boiler capacity is available to both space heating and domestic hot water.
The CX 150 delivers about 4.1 GPM at a 70°F temperature rise; the CX 199 delivers about 5.5 GPM. Wall-hung mounting frees the floor space a tank-and-boiler pairing would take up.
Condensing efficiency with deep modulation
At 95% AFUE almost every dollar of gas becomes usable heat. A 10:1 turndown (CX 150: 15–150 MBH input; CX 199: 20–199 MBH) lets the burner throttle right down for mild days and up for deep cold, which keeps water temperature steady and cuts short-cycling.
