I have a few 55 gallon drums of water in my greenhouse for thermal mass. They help for sure, but in the dead of winter, there’s only so much they can do.
I was thinking I could use a spare panel connected directly to a metal element of some kind in a barrel. Nothing fancy - literally just something that would convert whatever sunlight is available to heat, which would be passed to the water.
Anyone have more knowledge on how this might work?
