JAB Framed Units are a pre-plumbed packaged hot water unit that combines a Grade 3 copper cylinder with a black polythene cold feed tank. It is a complete steel-framed unit with interconnecting pipework, which reduces installation costs. 

JAB Framed units offer a practical and efficient solution where space and easy installation are important factors. They are suitable for properties without loft space, such as flats, bungalows and bedsits.

They are available for direct and indirect systems. The direct version comes with bosses for side-entry immersion heaters. Extra tappings and immersion heater bosses can be fitted, to suit individual requirements. It can also be used in conjunction with low tariff electricity.

The indirect unit is for use with a central heating system. They have an integral feed and an expansion tank within the cold tank for the central heating side. An immersion heater can be fitted to indirect units for use as an electrical back-up.
