A non-condensing twenty-three year old Vaillant Turbomax Plus 837e combination boiler had reached the end of it's time supplying heat to an S-Plan system for heating and hot water.
The customer chose a Glow Worm Energy 35C A rated condensing combination boiler as its replacement. A Glow Worm System magnetic filter was fitted to help provide protection for the boiler from magnatite (black sludge). Existing controls were utlilised in this instance as the S-Plan was to remain in place at the time of installation which incorporated a 250 litre unvented (G3) hot water cylinder.
The system has recently received an upgrade, all hot water coming direct from the boiler and a Boiler Plus programmable room thermostat (to meet Document L of the Building Regulations) now controls the heating.
