Economy 7 (Maxistore) Copper Cylinders

Economy 7 (Maxistore) cylinders and combination tanks are designed to take advantage of the various cheap rate and night-time tariffs of by electricity providers.

What is ECONOMY 7

At night, the cost of electricity drops considerably with demand. This is an ideal time for the householder to take advantage of cheap rate fuel and heat domestic hot water. Economy tariff electricity can be used exclusively, or in conjunction with an indirect heat source (such as a boiler).

Direct Economy 7 cylinder

Economy 7 (Maxistore) Direct cylinders are generally designed with two heating elements. The lower of the two heats the cylinder overnight, the upper is utilised as a 'boost' element.

Indirect Economy 7 cylinder

An Economy 7 cylinder may also be fitted with a boiler coil. If so, the cylinder can be heated by a boiler as required but can also take advantage of cheap electricity when available.

Extra thick Economy 7 insulation

Because Economy 7 cylinders are generally heated overnight they are invariably coated with a double-thick (50mm) coat of insulation that dramatically reduces any standing heat losses, ensuring the cylinder is still full of hot water by morning.

Please note: Economy 7 insulation is 50mm thick. Dimensions stated below do not include the insulation. Therefore, 100mm must be added to the diameter.
