Sensible Efficiency

For electric to succeed, it is vital that every watt of
input finishes up as useful hot water and heating. The
new range of E-Tech S Tank-in-Tank thermal storage
units is designed to do just that. Four conveniently-
sized models are available and each benefits from the
clever integration of our stainless steel Tank-in-Tank
technology with an equally advanced electric boiler
control system. Cupro incoloy elements within the
primary water provide the electrical energy.

How It Works

An inner stainless steel hot water storage tank draws
heat from primary water circulating through an outer
tank which is heated by heavy duty elements. As
they're immersed in primary water only, the heating
elements are unlikely to be affected by scaling and
input to them is modulated by a dual stage thermostat
to reduce cycling and load switching. The special
design of the inner DHW tank not only helps ensure
scale-free operation, but also avoids the sediment
problems that plague conventional cylinders. To fully
utilise generated energy the Tank-in-Tank unit is
wrapped in a generous 70mm of polyurethane
insulation.
