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.

Water Tank With CAT5 AB Airgap

These cold-water header tanks are available with a CAT5 AB air gap which is backflow and back-siphonage prevention device protecting the incoming mains water from contaminants which may have entered the cold water storage tank. These tanks are available up to 30,000 litres.

Insulated Water Tank With CAT5 AB Airgap

These insulated cold-water header tanks are tanks with a CAT5 AB air gap which prevents against backflow and back-siphonage.  Closed-cell polyurethane foam is used to reduce heat gain and heat loss of the water for installations such as plant rooms (heat gain) or for external installations (heat loss). These tanks are available up to 30,000 litres.

Colour Options

Tanks in colour options other than black, such as blue, natural, and dark green, are considered as bespoke items and are non-refundable.  Similarly, non-standard outlets are also non-refundable.
