Potterton Boiler Installation in Gravesend – Back Boiler Upgrade

We were contacted by a homeowner in Gravesend who was struggling with an aging back boiler unit situated behind their fireplace. These older systems are notoriously inefficient and often difficult to service due to limited access and the lack of readily available spare parts. The customer reported that the system had become unreliable, frequently failing to fire up, and was causing significant fluctuations in water temperature throughout the home. Upon inspection, our engineer identified signs of corrosion within the system's pipework and determined that the back boiler was reaching the end of its operational lifespan. The setup was also taking up valuable space and prevented the customer from modernizing their living area. Given the age of the unit, it was no longer meeting current energy efficiency standards, leading to spiraling gas bills and persistent maintenance headaches that made a full system upgrade the most cost-effective solution.

Our team began by safely decommissioning the old back boiler, which involved the careful removal of the fire unit and the draining of the outdated gravity-fed system. We then completed a comprehensive power flush of the existing pipework to clear out sludge and debris, ensuring the new installation would operate at peak efficiency. We installed a new, high-performance Potterton boiler in a more accessible utility space, integrating it with a modern sealed system and upgrading the controls to a smart thermostat. Following the installation, we meticulously checked all gas joints for leaks using a digital pressure gauge and conducted a flue gas analysis to ensure optimal combustion. We also installed a high-quality magnetic filter to protect the new boiler's heat exchanger from future debris accumulation. Finally, we commissioned the system, verified the flow rates, and calibrated the pump settings to ensure balanced heat distribution throughout the entire property, leaving the customer with a reliable and efficient setup.
