Solar Radiant Heating System
with Heat Rejection Loop
 
HEAT REJECTION

 

To avoid system stagnation in a solar assisted radiant heating system, a heat rejection loop removes excessive heat in cooling seasons. The heat rejection loop can be a copper coil, fan, or the snow melting mash.

An example of a solar assisted radiant heating system with heat rejection loop.

OPERATION:

  • The solar collector heats the solar storage tank through the bottom coil in the tank.
  • The top coil in the tank supplies heat to radiant heating loops.
  • When the temperature at the tank bottom coil falls below 120ºF, the high efficiency boiler will add heat and maintains the temperature in the top half of the solar tank.
  • Heat rejection loop removes excessive heat in the summer operation mode
