Hot Water Storage - Joule

The Joule Copper and Stainless Steel Thermal Stores are the next generation of heating and hot water production. The Joule thermal store has been designed with multi fuel heating systems in mind. The cylinder allows an easy installation of solid fuel, solar and boiler easily and effectively. The thermal store allows pressurised hot water heated from solid fuel safely and fully compliant with current plumbing practices and standards. The tank operates like a hot water cylinder in reverse. The tank is completely full of heating system water, the domestic hot water flows through a network of coils up through the centre of the tank supplying you with high flow rate pressurised hot water at piping hot temperatures. The thermal store is ideally suited to providing solar heat support and domestic hot water production simultaneously and easily.

Copper or Stainless Steel?

When choosing your Thermal Store it is important to consider what pressure the heating system will be operating at. Our Stainless Steel thermal stores are better suited to high pressure heating systems because of their higher tensile strength. Our Copper thermal store is a better choice for areas of hard water. While Joule always require hard water to be treated so that is maintained below 200ppm Total Hardness in water conditions where the untreated levels are higher than this figure the Copper Thermal Store is recommended.
