Thermal Stores, Calorifiers & Retrofit Coils

Domestic Applications

On the Go- Camper Vans and Boat Applications

The Solar Thermal Store unit provides hot water via a thermal 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 Solar Thermal Store can be located almost anywhere within the dwelling or business premises. Simple to install with no requirement for an unvented certificate and being able to take various heating inputs the Solar Thermal Store offers far greater flexibility than the vented or unvented units.

In addition to having the components required for solar heating, the Solar Thermal Store can have as many direct tappings per your requirments which can be used for heating the stored water by various other means, such as, woodburners, pellet/ biomass boilers, range cookers, or other gravity circulating applications. These direct tappings can also be used to take heat from the stored water for the purpose of heating the premises via open vented radiator circuits, heat dump or under floor heating circuits. The same can be done indirectly by fitting the Solar Thermal Store with a high efficiency coil, allowing the radiators and/ or underfloor heating circuits to be installed as sealed systems.

Supplied with a Taconova mixer valve, a 2 litre expansion vessel, a pressure reducing valve and check valve – all fitted to the external pipework.
