Product Code:

Maxistore was developed for use on an open vented system in electric only applications. The cylinders carry full Economy 7 accreditation and are manufactured to BS1566:2002 (Part L).

To ensure maximum efficiency the cylinder is foamed with 50mm thick insulation, which reduces the heat loss values. Two side entry immersion heater connections (2 1/4") are fitted as standard to maximise the use of Economy tariff electricity.

Later versions of the Maxistore range incorporated a combination-style variant, to remove the need for a feed tank in the roof space and ease installation. Telford Copper Cylinders can also supply, as a cost option, suitable immersion heaters and economy tariff time clocks. These can be supplied either factory fitted or supplied separate for on-site installation.

Copper vented cylinders come with a 10 year guarantee.
