The Oregon Package is the smartest and the most efficient solar system.  It is a Closed Loop Solar Heating System and is suitable for cloudy regions. This package is also the preferred option for extremely cold areas. The upper coil can be used in the future for other applications such as space heating or spa heating.

5 .Tempering Valve 11. Circulating Pump with flanges or couplings 17. Immersion Heater
6. Collector Return 12. Pressure Relief Valve 18. Controller

Operation:

  • The Controller (18) will switch on pump P1 when the temperature at the collector sensor TC is higher than the return temperature TR by at least the pre selected amount.

  • Pump P1 circulates a heat transfer fluid around the loop through the upper heat exchanger.

  • When a preset tank temperature (e.g.. 130 F) is reached at TT, the controller  starts the pump 2.

  • With the pump running, if delta T is less than preset value, all pumps will switch off.

  • When a preset tank temperature is reached at TMAX, the controller switches off both pumps.
  • The check valve (non-return valve) prevents heat from the tank rising towards the collector should the tank be warmer (e.g. at night).
