Natural pond heating, no electricity

[charles-n-charge]

It could work, I'd read a lot and make a more few designs. I would bury the pipe as deep as you can, from caving I can tell you that most caves once you get in them are right around 53F.....Do your fish a favor though and run it without fish for at least one winter and make sure you can keep the temp fairly steady.

That's what I plan to do unless I'm about to get one of those floating solar power pool heaters real cheap

Make a waterfall area that's black, the black draws heat to it and the waterfall distributes the heated water


Idk about night though :/

look around for a washing machine heater. Problem solved, except for the whole"electricity" thing

Solar... powered... heater. It will heat the pond all day as necessary and during the night put a pool cover over it and it will stay plenty warm.
