We systematically test gas tightness, expansion vessel pre-charge, thermal safety cut-offs, ionization probes, circulation pumps and 3-way diverter valves to prevent repeat breakdowns.

- Hydraulic pressure check, 3-bar safety valve and air bleed inspection
- Flue-gas combustion & carbon monoxide (CO) safety test
