Boilers: Combination, System, and Regular
Regardless of whether it's a combi, system, or regular boiler, our void check goes beyond the standard flue gas analysis. We visually inspect the appliance for signs of leaks or corrosion. Internally, we check the main heat exchanger, burner, and ignition system for cleanliness and correct operation. Crucially, the expansion vessel pressure is verified and recharged if necessary. The pressure relief valve is also tested to ensure it operates within tolerance, preventing future over-pressure scenarios. We also confirm adequate ventilation according to manufacturer's instructions.
