Our domestic Boilers can be very expensive to repair and a lot more costly to replace, so it makes sense to keep your boiler in good working order. Regular maintenance will not only save you money in the long run but could also save your life as a faulty boiler can be fatal. Also, a healthy boiler is far more efficient, so can lower your energy bills. It might be that you are confident and practically minded enough to complete this on your own, but you must be aware of the safety procedures and regulations before attempting to work on such equipment. A Plumber will service and repair any piece of plumbing equipment. To keep the boiler healthy, try and use the system at least on at least one occasion every four weeks or so. This will flush the pipes/ radiators and pump and not allow sediment to settle, and also visually check that all flues and vents clear and not covered. It is Recommmended that you seek the services of Gas safe registered engineers like London Plumbers to guarantee that it is running correct and safely, and finally, fit some carbon monoxide detectors around the house. If a leak is detected, call the National Gas Emergency Service immediately on 0800 111 999. If all these boiler checks are within the regulations, then, a gas safety certificate (CP12) can be issued: Inspect for the provision of all necessary ventilation, and check combustion products are removed by testing the flue flow parameters. Flame Out Devices are tested for correct and safe operation. Appliances (gas) must be checked for thorough gas tightness. Gas Safe Engineers check burner pressure and gas rate and compare with the manufacturers information. NOTE: If you ever suspect a gas leak you must immediately contact the National Gas Emergency Service immediately on 0800 111 999.
