What's the thermal output you get from this?
I mean how many litres of water can you heat per day during summer if it's in the direct sun?
Would it be enough for two showers?
How about using old aluminium cans flattened out?
Can you use plexiglass instead? I'm thinking for clumsy people it might be a better option
Ok… I see you Mr. Harbor Freights drill.. ๐ My favorite place to shop. You have the best video I had seen that produces the most efficient way of a solar heater for a pool.
i was about to comment how reflective copper is to infrared light and then i saw you blacked it. pretty ingenious to use black copper oxide to increase light absorption
for the wood, drill the outer hole the correct diameter. then drill with a smaller bit through that outer hole into the wood piece that you will join together with the screw. this allows the screw to pull the outer piece towards the smaller hole piece, creating a tighter fit.
It would be very much appreciated if the hook ups could be more specific, as far as the warm water hook up is concerned – just with garden hose into the bathtub?๐
Thatโs not enough flow to heat a bathtub full of water in one day. When I was a kid we would put about 10-15 gallons of water in a galvanized tub out in the sun all afternoon to heat it for our bath.
As I live in the desert, I just painted the backplate black with High Temp BBQ spray paint. I would suggest not using plastic zip ties. Even UV treated ones are going to break down in a year. Get VKTech stainless zip ties. 100 ARE ONLY $10.. https://www.amazon.com/Vktech-100pcs-Stainless-Exhaust-Locking/dp/B00CTKBTH2/ref=asc_df_B00CTKBTH2/?tag=hyprod-20&linkCode=df0&hvadid=198062682203&hvpos=1o5&hvnetw=g&hvrand=823056130660073100&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031411&hvtargid=pla-319814610888&psc=1
How long after sunset does the water stay warm?
