Hot Water Cylinders and Pipes:Modern cylinders are made with an outer layer of foam insulation, but if you have an older un-insulated cylinder you could start by lagging it using a segmented mineral-fibre jacket. At the same time, lag the hot water pipes that run through unheated areas of the house. These simple measures will guarantee savings over a short period of time. An Enfield Plumber can insulate cylinders.Radiators:Fitting a foil lining behind the radiators against external walls is a good measure. This will reflect the heat back into the room, rather than being absorbed by the wall. Fact: As much as 25% of the radiant heat from a radiator placed against an outside wall is lost. S applying the foil is a good idea.Foil Faced Expanded Polystyrene Liner:This foil is supplied in rolls, sheets or in tile form. It is easiest to apply with the radiator out of the way such as when you are decorating. Although it is possible to apply with the radiator in situ. Enfield Plumbers use this type of foil liner.To Fit:1). Turn the radiator off and measure it, making a note of the position of the brackets. Use a sharp trimming knife or scissors to cut the liner to size, so it is slightly smaller than the radiator all round.2). Cut narrow slots as required to go around the brackets and apply heavy duty anti fungal wallpaper paste to the back of the liner and slide it behind the radiator if fitted. 3). Smooth onto the wall using a wooden batten or a small roller, the sort used for painting radiators. Let the paste dry before turning the radiator back on again. Alternatively, you can fix the liner in place using some good quality double-sided adhesive pads.
