Forced Circulation Systems
Forced circulation systems
Forced circulation systems are the most widespread systems, throughout Central and Northern Europe, since low temperatures, consist a restrictive factor regarding the placing of the storage tank. The specific hydraulic drawing is indicative, consists of the storage tank, the collector, the mounting system, the solar station, the solar controller and certain installation parts.
The biggest advantages of the forced circulation system, compared to the thermosiphonic are the following:
- Fewer heat losses of the storage tank, since the tank is located internally.
- System automation
- Bigger system flexibility, resulting to a higher general efficiency.
