An Economy 7 cylinder is designed to exploit 'off-peak'
electricity, typically available throughout the night. A feature of an E7
cylinder or tank is the addition of a second immersion heater (unlike a
standard direct cylinder that only has one). The lower of the two
elements is typically connected to the economy supply/tariff, the upper
heater is usually used as a boost element and operated manually when
demand for hot water is high. Our cylinders are supplied with the two
immersion heater bosses (the bit you screw the heater into) but
immersion heaters are sold separately. Please enquire.
Because you are
heating your cylinder overnight it is important to not to loose the stored
heat by the morning. Economy 7 cylinders are therefore fitted with an extra thick jacket of
insulation - typically 60mm thick, as opposed to the 30mm jacket on a
standard cylinder.
Value, Quality, Efficiency and Discount !
PLEASE NOTE:
Economy 7 cylinders have an insulating layer approx 60mm thick for enhanced
performance. You must add this to the dimensions shown on the table below
for over all measurement.
(i.e a 450mm diameter = 570mm including
insulation [2 x 60mm]) |
