If your hot water cylinder is insulated, your hot water will stay hot for longer and you will waste less energy heating it.
How it works
The solid foam surrounding or jacket of a well-insulated hot water cylinder or tank will keep your water hotter for longer and you will waste less energy heating it.
How it is installed
Hot water cylinders or tanks should have solid foam insulation fitted in the factory or an insulated jacket. Insulating a cylinder or tank can be a DIY task. If the cylinder or tank is bare or the layer of foam is so thin that it gets hot, fit an 80mm insulating jacket.
