A vented hot water cylinder has a header tank which is commonly situated in the loft of your home. The vented cylinder relies on the header tank to provide it with mains fed cold water and relies on the gravity system to pass the water through the pipes to the hot water cylinder.
The cold water is then heated either from an electric immersion heater within the hot water cylinder (direct) or via the central heating boiler (indirect). This will determine if you need a direct vented hot water cylinder or vented indirect hot water cylinder.
