Normally the hot water storage cylinder will be stuated in an airing cupboard although they can be found in a loft. Lots of homes in the UK still have no insulation on their hot water cylinders, and this results in the escape of heat that could be avoided. The fitting of a jacket for the hot water cylinder, will insulate it and reduce the rate of any heat loss, which will help to keep the water temperature steady in the tank for many more hours if not days. Heat loss from a cylinder can be reduced by around 75%, and this will help to save around £50 per year on an average energy bill. A Walthamstow Plumber can insulate cylinders. Jackets typically come in two standard sizes: 900mm x 450mm and 1,050mm x 450mm. It is recommended to but a cylinder jacket that displays the British Standard Kitemark. They typically cost up to £15. Walthamstow Plumbers use this type of foil liner. If there is already a hot water cylinder jacket fitted, it is a good idea to consider replacing it if measures 75mm thick or less and it does not cover the cylinder completely. The jacket is easy to fit by, simply wrapping it around the cylinder and tying it with string or a cord. 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. 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. As much as 25% of the radiant heat from a radiator placed against an outside wall is lost. So applying the foil is a good idea. The 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.
