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.
