hot-water storage tank

A tank that meets code requirements for storing hot water. These requirements depend on its size and pressure as well as the authority having jurisdiction. The volume of the tank usually is selected so that 60 to 80 percent of the volume of water in the tank may be drawn off before the temperature drop of the water in the tank is unacceptable.

The initial cost can be fairly high, however, it is important to prioritise - start with a few relatively inexpensive measures, such as insulating your hot-water cylinder and draught- proofing windows and doors, then do the more expensive things bit by bit - for example, insulating the floor, roof and walls or installing double glazing.
