Project Overview

Saintfield-based specialist civil engineering and piling firm Dawson Wam removed the business overhead of heating and hot water for the next 20 years by upgrading their traditional LPG heating system to a locally designed and manufactured biofuel heating system to qualify for the Renewable Heat Incentive (RHI).


- Replacing outdated existing heating system with a state-of-the-art biomass system
- Merging five existing LPG systems into one streamlined system
- Upgrading system controls to provide better climate control for Dawson Wam’s office suite
- Reducing business overheads
- Reducing carbon and CO2 emissions
- Assisting in RHI application and acceptance
- Providing guidance and support




The company invested in a new BSH 99kw modularised biofuel system which displaced the previous LPG and oil boilers. The new system, which is accredited to run under the NI Renewable Heat Incentive includes high-tech controls to ensure optimum system performance as well as producing online reports for operators to monitor the system’s performance and company’s fuel consumption and emissions.




This innovative modularised system, which is accredited to use under the NI RHI scheme, has enabled the firm to make an immediate savings of 120% on its energy bills and going forward will completely remove the business overhead of heating and hot water until 2033.

- Sustainable heating and cooling
- 68,300kg Green House Gas emissions reduction
- Acceptance into the RHI
- Free heating until 2033

“The immediate removal of heating costs through installing the BSH biofuel system at our head officewas something which was very appealing to us. The new data logging system with the BSH module is easy to use and monitors all our utility costs, and records and compares what we used this term with previous terms and provides us with GHG emission reduction figures all via the web.”
