Commercial Solutions

Gas Boilers

Collectively, we’ve been at the forefront of boiler innovation for more than 150 years, creating scalable and flexible heating solutions that are built to last.


Our revolutionary systems set the standard for reliability. They’re all designed to maximise boiler efficiency and reduce both energy usage and NOx emissions.


With a wide range of either stainless steel or aluminium heat exchanger options available, we have a solution for every application. We know that optimal performance is vital, but so is usability.

All our boilers are ingeniously streamlined, straightforward and simple to install, whether stand-alone or in cascade. We’re also future-proofing them with the latest smart control technology that makes operation and maintenance even easier.

Cascade Systems and Pre-Assembled Rigs - Commercial Heating and Hot Water Solutions

Cascade Systems and Pre-Assembled Rigs

Our flexible range of easy-to-install boiler cascade systems increase heating reliability and efficiency. Spreading the total required heat output over several boilers in cascade configuration offers many advantages, such as standby capability and a better turndown ratio.


We also offer boiler rig systems, making installation quicker and easier as the boilers are delivered on site in a pre-assembled wheeled unit. Quality control is also improved as the pre-configured unit is pre-tested and delivered as a whole system, rather than as individual components – reducing downtime and on-site labour.
