Results For DIY Solar Heat Exchanger With 4" In Line Inlet Fan VID#2

This is video #2 of the final test day for Dave's Do It Yourself Boutique Solar Heat Exchanger with a Inline 4" inlet fan.

Our Final Results For A 2 hour test:

4" inline inlet fan
Outside air temp 45F
Clear skies with full sun
Output temperature at 4' from the top averaged 85 - 93F
Internal temp above the heat exchanger chamber averaged 125 - 132F.
Suncourt DB204 Duct Booster 4 DI $25-30 Home Depot or Amazon.

Conclusion: The Boutique Heat Exchanger Design does very nicely maintain acceptable output temperatures when with an airflow of 60-80 CFM.

Note After Tests: The outlet pipe of approximately 4-5' was not insulated. If insulated, the outlet temp most likely would have been 110-115F, not 80-95F.

I built the solar heater. How do I automatically turn my fan on when the temperature in the solar heater is high enough?

So how about putting a link to your website in the description?

Do you run your inline fan off of a solar panel?
