our range of solutions
Sustainable Commercial Heating Solutions for Every Sector
Public Sector and Infrastructure Decarbonisation
Navigating the Public Sector Decarbonisation Scheme demands auditability, long-term accountability and a supplier who understands governance. We support estates managers across healthcare, education and government with commercial air source heat pump systems that guarantee performance and political safety. Our team helps turn complex grant applications into operational, low-carbon heating reality.
Commercial Retrofit and Boiler Replacement
Replacing an ageing commercial boiler with a low-carbon alternative should not mean compromising your building's flow temperature or tearing out the existing emitter network. Our high-temperature heat pumps deliver up to 85°C using R290 natural refrigerant, making them the ideal solution for decarbonising existing commercial buildings without a costly full refit.
New Build Design and Specification
For the building services consultant, precision is everything. We provide comprehensive engineering support from project concept through to final commissioning. Whether you are designing a BREEAM-certified office block, a high-capacity distribution warehouse or a mixed-use development, we supply the CAD/BIM files, performance curves and selection data to ensure your specification is robust and your professional reputation is protected.
Commercial Hot Water Generation
Dedicated and combined DHW solutions for buildings with high hot water demand. R290 systems delivering up to 85°C for legionella-compliant hot water production in hotels, hospitals, care homes, leisure centres and student accommodation.

The Intelligent Comfort Guarantee: Support That Never Sleeps
The commercial HVAC industry has a trust problem. Consultants specify equipment, contractors install it, and when something goes wrong, the supplier is nowhere to be found. We built the Intelligent Comfort Guarantee to fix that.
