solar powered bird bath heater Answered

Looking for instructions on how to make a simple, inexpensive solar powered heater to keep my bird bath water from freezing in the Winter.

I want one too!
Something like this one looks easy( ish)

anyone know how it is constructed?

do you want warm water or just un frozen water?

My solution to this was to add hot water (just off the boil for making coffee) to the birdbath on truly cold (10-25 F) mornings. If you truly get a lot of strong winter sunlight on freezing winter mornings, the solar heater could work - but check our local climate data for of cloud-free sub-freezing days before you invest too much effort.

If you're really want it to be heated you could do it caveman style, fire. If you can rig a low heat fire to a NONFLAMMABLE bird bath and kept it from over heating of exploding, I suppose it's possible.

Paint the bottom of the bowl black to absorb more sunlight. As lemonie says, you could use a pump, and you could supplement the power for it from the mains when there is not enough from the solar source.

Moving water is often effective - just run a pump. But if it gets colder than that you might be struggling with solar in winter. "Simple" and "inexpensive" make this a bit difficult L
