Concord CXSi/H

Ideal's Concord CXSi range offers reliable gas atmospheric cast iron boilers, available in outputs from 110kW up to 180kW.

The large output is achieved by a bigger heat exchanger than a standard commercial boiler, which is assembled side to side, making the unit wider to enable up to 9 burners.

The CXSi has a modern control facia, with simple analogue controls incorporating warning lights for boiler on, overheat lockout and burner lockout. Optional remote indication kits provide volt free contacts for boiler performance monitoring.
