Cold Water Header Tanks
Our cold water header tanks and AB air gap tanks are ideal for new builds and replacement of existing tanks. A header tank is usually used to fill the heating system and accommodate the expansion of water from the heating system during the heating cycle. These are generally connected to mains water supply, they should have a screened overflow pipe to a drain, a mains water supply connecting to the tank with a ball valve to fill the system.
