The Joule Cyclone Thermal Store 2.0 is the ideal solution for multi energy applications. The hot water is produced through the fresh water module mounted on the front of the tank. This provides far superior flow rates compared with the older internal coil version. The tank has many direct connections to allow for multiple heat sources and heat zones. The tank ismanufactured from stainless steel and has the usual quality outer casing that you expect from a Joule Cyclone cylinder.
