Solar heating systems can be categorized into Natural (Thermosiphon) and Forced Circulation Systems.
Natural Circulation Systems, most commonly used with solar collectors and storage tank together, use the thermosiphon principle. These are usually available in capacities of 150, 200 and 300 litres. Multiple systems can act together to cater to central water heating requirements.

Forced Circulation Systems, mostly used for Industrial & Commercial applications. Solar Collectors and Storage Tanks are split with pumps (and accessories) with the aid of an intelligent solar controller, which operates the system effectively. The standard capacities for these systems are available from 200 up to 5000 litres and even to 10000 litres storage as a single system. Larger capacities are also possible with multiple configurations of the units.
