Oil burner overhauls
Full teardown of burner blast tubes, photo-resistor testing, and optical flame sensor cleaning. We replace fluid nozzles to factory spec and calibrate oil pump delivery pressure to prevent sooting.
Hydronic circuit balancing
Differential temperature diagnostics across flow and return lines. We adjust lockshield valves across each manifold to eliminate cold radiator spots and stabilize return water temperatures to protect heat exchangers.
System powerflush restoration
High-flow magnetic filtration flushing mobilizes dense black iron oxide sludge from aging pipework. Chemical descaling eliminates circulation pump strain and restores full thermal transfer across all domestic radiator loops.
Four-step diagnostic sequence
Fuel line and filter check
Combustion chamber service
Flue gas analysis
Performance printout verification
Calibrated electronic probe sampling measuring carbon monoxide, carbon dioxide, oxygen ratios, and flue discharge temperatures under active firing conditions.
Inspection of external oil storage tanks, paper filter bowls, and remote fire isolation valves to guarantee clean, uncompromised fuel delivery.
Baffle plate extraction, mechanical soot removal, and electrode gap gauge alignment inside the primary heat exchanger casing.
Immediate printed diagnostic logs recording gross efficiency, net efficiency, and draught pressure readings for warranty compliance and documentation.
An oil boiler running out of calibration by even two bar of pump pressure wastes fuel and fouls heat exchanger baffles within months. We verify combustion down to decimal percentage points before signing off.
Lead Heating Diagnostic Technician
