Nearly all British homes use hot water tanks to store their hot water. A significant amount of the heat generated by hot water tanks is wasted heating up the area surrounding it. This can be reduced by up to 75% by surrounding the tank with an insulating jacket. The jacket prevents most of the heat from escaping, which means the tank has to work less to keep the house warm. Jackets should be at least 3 inches thick, and should not have any gaps.
The use of an effective hot water tank insulation jacket is inexpensive, and the initial cost is offset by the heating bill savings within a year. It is important to ensure that jackets are fitted properly by a professional. An incorrectly-fitted jacket will be a lot less efficient than a correctly-fitted one.
