The header tank, otherwise known as the feed and expansion tank or cistern, is an essential part of an open vented central heating system with a regular boiler. The role of the header tank is to supply water to the central heating system and also maintain the level of water, which expands when heated.Click to see full answer. Similarly, what is header tank used for?The header tank is used to fill the heating system and accommodate the expansion of water during the heating cycle. It has an overflow pipe running to outside, a mains water supply connecting to the tank via a ball valve used to fill the system and a cold feed pipe* and an open vent pipe*.Likewise, do you need a header tank? A regular boiler will always require a hot water tank and may also require a cold water header tank in the loft, depending on whether you are operating a vented or unvented hot water cylinder system. For this reason no cold water header tank is necessary. Subsequently, question is, how does a feed and expansion tank work? The feed and expansion tank, header tank, or feed and expansion cistern as it is technically known, is a cistern which supplies the central heating circuit with water and accommodates the expansion of the water when it is heated by the boiler. It is typically made out of plastic.Why is my header tank hot?Another frequent cause is a blockage where the feed / vent pipes from / to the F&E tank join the main pipework. That causes hot water to go up the vent into the small tank whence it is dragged back into the system again via the feed.
