Condensing Gas Boilers

We offer a wide range of both wall mounted and floor standing commercial gas condensing boilers for the provision of space heating and hot water. All our boilers are manufactured using stainless steel heat exchangers, high efficiency low NOx pre-mix burners and all are compatible with a 20% Hydrogen mix with Natural Gas.

Wall Hung Boilers (60-180kW)

For installations where wall mounted boilers are preferred choose from either the white cased S-CB+ (60-180kW) or the black cased second-generation S-CBX (85-155kW) range with ultra-low NOx emissions. Both versions are available with frame and hydraulic pipework kits and can be supplied with a matched low loss header or plate heat exchanger.

All models in both ranges are supplied with a matched circulating pump. The S-CB+ pump is located inside the boiler casings (other than the PX120 model) whereas the S-CBX pump is positioned in the pipework below the boiler.

All models in both ranges are over 95% efficient (Part L method) and can be cascaded together with the maximum number being 16 boilers. The S-CBX model benefits from extremely low NOx emissions, lower than 24mg/kWh as standard without the requirement of modifying any combustion setting or fan speeds thus guaranteeing the lowest NOx emissions as possible.

Floor Standing Boilers (70-600kW)

For installations requiring higher power outputs floor standing boilers are often preferred. In this case choose from the S-CB FS (400 and 550kW) or S-FX (70-320kW), or S-FAX (100-600kW) range.

All models are supplied with wheels for easy plant room positioning.

The S-FX range also benefits from large water content design and, as well as offering over 96% Part L seasonal efficiency, can operate with a wide flow and return temperature range (from 5 to 50°C DeltaT) making it an excellent choice for systems incorporating heat pumps as the primary heat technology.

The S-FAX range offers best in class modulation range, making it ideal for retrofit installations, where load matching is of paramount importance.
