Item works rarely unless full, full bright sun. There is very little heat from this unit, certainly not enought to augment any other system.

    Disappointed in this product
    I was very disappointed in this solar heater. I followed the instructions and even took off the plastic coating. This solar heater does not work through thermal windows. It was bulky and heavy. No heat came out at all after trying it out for two weeks.

      Perfect supplementary heater for my dog kennel during sunlight hours!
      This unit produces 910 BTU in a 100 sq.ft. dog kennel over 10 hours. My dogs are warm and my propane heaters are off all day ! Thank you Solar Infra Systems ! My chickens will thank you next week when I hard mount my second unit on the chicken coop ! My Anemometer measured 55' outside and 72' at the heater output ! And Zero fuel, Zero emissions !
