Your Biomass Boiler Should Burn Clean, Not Cost You Money
Poor combustion. Rising fuel usage. Falling output.
If your biomass system isn’t running properly, it’s not just inefficient, it’s costing you every day it’s left unchecked.
We diagnose, fix, and optimise biomass boilers to restore proper performance.
Most Biomass Boilers Don’t Fail, They Drift
Over time, even well-installed systems lose efficiency:
Heat exchangers clog and restrict output
Combustion settings fall out of calibration
Air and fuel balance becomes unstable
Components degrade without obvious faults
The system still runs, but not as it should.
What We Do
Every job is approached as a performance issue, not just a checklist.
Full servicing includes:
Air/fuel calibration
Component inspection and fault identification
System performance optimisation
Deep internal cleaning
(including heat exchangers)
Combustion analysis and tuning
Real Systems. Real Fixes.
