Hey I could use some advice
I have a small solar water heating system I build myself this fall, to heat my trailer (and hopefully DHW come the summer). but the loop that bring the heat from the storage tank to heat the trailer, isn't. I am trying to use thermosiphonic action to circulate the water in this loop. but no heat seems to be being transferred. I attached a simple diagram of it. my storage tank is a 55 gal. drum, the lines are 1/2 CPVC, water-to-air heat exchange is a radiator from a 90s Honda Civic. my storage tank as be running 80-90*F but at the exchange it is only 50-60*F (room temp). so it seems that it is not thermosiphoning. does it matter that the tank waters surface is below the heat exchange? what did I do wrong?
Thanks!
