Our Commitment

In larger establishments such as houses, offices, social clubs, schools, golf clubs, and churches, boilers with outputs over 50kW are often necessary. When installing commercial heating systems, it’s crucial to consider future maintenance and repair needs. Working on such large systems can be both time-consuming and costly.

Therefore, we prioritize the installation of necessary controls and isolation valves to streamline maintenance procedures. While this may entail additional upfront costs, it ultimately saves money over the system’s lifespan. Our quotes for installation work include the provision of appropriate controls and components aimed at enhancing fuel efficiency and minimizing maintenance requirements.

Our Team

Our team comprises engineers who possess specialized skills and qualifications specifically tailored for working on individual boilers or groups of boilers exceeding 50kW in the commercial sector. We ensure that our engineers are equipped with the necessary expertise to handle the complexities associated with larger heating systems efficiently.
