The Solahart Heat Store Series II system is designed to generate maximum performance in most climatic conditions, in combination with our high performance Bt collector. The tank is well insulated and the copper coils inside the closed circuit water provide ample hot water under high pressure with large flows.
The system can provide hot water only or hot water in combination with floor heating and/or pool heating. The intelligent controller controls all active components of the system; from the amount of solar gain and supplementry boosting to regulating floor and pool heating. Additionally the data from the controller can be logged and viewed locally or remotely.
Principles of Operation
The system is utilises a large capacity storage vessel filled with heat exchange fluid. Immersed in the fluid is a copper coil through which the potable water is circulated providing instantaneous heat.
When the unit is in standby mode the heat exchange fluid drains down from the collectors and is stored in the main storage vessel. When the controller senses a temperature differential of more than 5 degrees Celuis between the collector and the lower tank the system switches to active mode.
In active mode the system pumps the heat exchange fluid from the storage vessel into the collectors where the solar heating occurs. Once the system is completely filled the controller will adjust the speed of the pump to ensure the maximum solar gain is achieved.
The fluid level in the tank will go down depending on the collector field size. The heat exchanger coils will stay under fluid level all the time.
When the system has reached its maximum temperature, or, there is no more solar gain possible, the system switches back to standby mode, allowing the heat exchange fluid to drain back into the storage vessel.
This 'drainback process' helps prevents overheating and/or freezing of the collectors during times of inactivity.
