Alpha Combi Boiler Installation in Orpington

The homeowners in Orpington were struggling with an outdated, inefficient gravity-fed system that relied on header tanks in the loft and a slow-recovering hot water cylinder. The system frequently struggled to meet the demands of their modern family bathroom, leading to low mains pressure and tepid shower temperatures that were becoming increasingly unreliable during winter months. Furthermore, the existing copper pipework was showing signs of significant corrosion, and the absence of a magnetic system filter meant that years of sludge buildup had likely compromised the efficiency of the radiators. The clients were tired of the constant maintenance required by the older system and requested a complete conversion to a sealed combination boiler setup to free up space in their airing cupboard.

Our engineering team began by power-flushing the entire heating circuit to remove stubborn magnetite and scale deposits, ensuring the new installation wouldn't be contaminated. We then removed the redundant hot water cylinder and cold water storage tank, creating valuable storage space for the customer. We installed the high-performance Alpha E-Tec 33kW combination boiler, which is perfectly suited to the home's heating demands. Precision was key to this upgrade, so we rerouted the primary flow and return pipes and installed a new gas supply line to meet current Gas Safe regulations. We fitted a high-quality magnetic system filter and a scale reducer to protect the boiler's plate-to-plate heat exchanger from hard water deposits. After final commissioning, we performed a thorough gas tightness test and checked the combustion performance using our flue gas analyzer to ensure optimal efficiency and safety.
