Annual Unvented Cylinder Service in Leeds
Your pressurised hot water cylinder works hard every day, storing hot water at mains pressure. Manufacturers such as Heatrae Sadia (Megaflo), Gledhill, Joule and Telford recommend a service every year by a G3-qualified engineer – and it’s normally a condition of the cylinder’s warranty. Regular servicing catches problems such as a flat expansion vessel or sticking valve before they turn into a leak, a dripping tundish or no hot water.
