2nd Solar Heating Loop with Boiler

 for Radiator or In Floor Heating





2nd Solar Heating Loop - Boiler

Integrate a solar water heating system into Home Heating with this quick Plug n' Save optional heating loop. The 2nd heating loop quickly plugs into the top heat exchanger found in either the SolarStor 80 gallon or SolarStor 119 gallon tanks.   The boiler loop is controlled by the RESOL controller and the Belimo valve.  If there is heat demand and the solar storage tank's top temperature exceeds the return supply of the boiler loop, then the valve is opened and the flow is diverted through the storage tank's top heat exchanger.  This way stored energy is transferred to the boiler loop providing energy to the home's heating system.  Optionally the 4.5 Kw heater can be turned on to guarantee energy even during periods of low sun.


Belimo Valve controls the flow of the boiler fluid to the solar storage tank




  • 120 VAC Belimo High Temperature Solar Diverter Valve 3/4"
  • 3/4" Brass Tee
  • 100 feet of Aurora Flex Stainless Steel 3/4" piping
