PIPE AND TANK INSULATION
Insulating hot water tanks and pipes will help keep your water hot for that nice long bath after a hard day's work. If you are having loft insulation installed, make sure that your cold water pipes and tanks are lagged to the proper standard - you don't want your pipes to freeze in cold weather because your expensive heat is now being kept in the living space where it belongs!
Fitting a British Standard "jacket" to your hot water cylinder will cut heat loss by around 75% and save you money. If you already have a jacket fitted to your hot water cylinder, check that it's at least 75mm (3") thick. If not replace it with a new heat saving one!
