Why Annual Unvented Cylinder Servicing is Crucial

Unlike regular hot water cylinders, unvented cylinders are directly connected to the mains water supply. This means they operate under higher pressure. A properly functioning pressure relief valve and expansion vessel are essential to prevent dangerous pressure build-up. Annual servicing by a qualified, G3-certified engineer is not just recommended – it's a safety requirement and often a condition of your cylinder's warranty.
