DIY "5 Gallon Bucket" Sand Battery Air Heater! Homemade Sand Battery Air Heater with Copper! Easy DIY! ~ How it works: room temperature air is blown over a very hot "copper topped" sand battery located inside the bucket. the copper strips act somewhat similar to the fins of a radiator - soaking up and spreading out the heat. the fan then blows down on it and the air is heated. air temps in the bucket top out around 140F(60C) so it holds up fine. bucket is rated to 230F(110C). there's also 3.5" of sand in the bottom and plenty of air space between the sides of the bucket and the sand battery. there are many ways to heat the sand. several 'on' and 'off grid' options are listed near the end of the video. an AC or DC fan can be used. many possibilities for a unit like this. good for on or off grid use. can be solar powered. if you like sand battery technology, be sure to check out my other vids on the topic. they are a new and exciting technology.

⭐⭐ As an extra, i've included a side-by-side with my "5 gallon bucket" air cooler (mainly because it looks very similar). note that each unit is made very differently though. you just add ice to that unit, and it blows cool air.
