Thermal Store Cylinders

Available both in cylinder and combination style, the thermalstore unit provides hot water via a mixing valve at high pressure supplied direct from the mains water supply. Requiring only access to a cold water mains supply and a facility to overflow to the outside (direct from the combination units and from a header tank for cylinder units), the thermalstore unit can be located almost anywhere within the dwelling or business premise. Simple to install with no requirement for an unvented certificate, the thermalstore unit offers far greater flexibility than the traditional vented unit.

All thermastore units are supplied with immersion heaters (two on direct models), drain valve, expansion vessel, thermostatic blending valve & ball valve (combination model only). Optional extras such as aqua control thermostat, pressure reducing valve and inline strainer are available if the customer requires.

Approximately 40 - 50mm foam insulation is applied as a standard, giving heat loss performance well above that required by Part L.

We also manufacture a cased thermal store unit.

We can also manufacture bespoke thermalstore units or replicate replacement units to suit the customers requirements.

Alternative heights and diameters are also available where space or water volumes are critical.
