ThermaCoil Direct Thermal Store

Available in sizes  150 | 175 | 215 | 255  LITRES

A direct thermal store cylinder for use in an electric only installation

The Plumbing Group are at the forefront of water heating technology. We are changing the way you think about water heating installations.  The ThermaCoil is a mains pressure open vented thermal storage system. It does not require safety valves and has no external discharge requirements.

ThermaCoil thermal storage systems works by reversing the function of the Primary (Heating) and Secondary (Domestic) water. The Primary water is stored in the cylinder and heated by either a boiler (indirect) or immersion heaters (Direct). When heated by a boiler, the water can also be pumped around either a wet central heating system or an under-floor heating system.

The Secondary water comes directly from the mains and passes through a specially designed finned heat exchanger coil which draws heat from the ThermaCoil. This water then passes through a thermostatic mixing valve which blends the water to the correct temperature before it reaches the taps.

ThermaCoil Direct Thermal Store

Available in four sizes ranging from 150 litres through to 255 litres. Our largest model is capable of satisfying the hot water demands of a property with 4 bedrooms, 1 bathroom and 1 separate shower room.

All models are pressure tested to 10 bar and come complete with two immersion elements and a TMV 2/3 blending valve.

The direct model comes complete with two immersions, one for on-peak use and one for off-peak use. This allows the store of water to be heated utilising off-peak electricity, making the unit extremely efficient.
