Mof, that looks just like the 'BOOSTER' on my parent's old yunca wegj

it used to boil the water in the cylinder

it was awesome

Unfortunately the steel pipe/cylinder made the water rusty in two days, had to dump the whole 1000L. Haven't got around to getting copper yet

Got some copper, thanks Jacknz123!

Had a few kinks from a previous coil attempt

Worked a few of them out and coiled it with the pipe bender for making truck mirror arms at work.

Now the fun part of trying to get it into the drum

Eventually got it in and fired it up tonight.

Was still very slow but definitely hotter.

Had it on for about 2-3 hours, the first 5-6 inches of water got to about 35° but the rest stayed at 20°.

I mixed it up and it evened out at 25°

A little more research on solar thermosyphon has has turned up the system works best if the bottom of the tank is about the level of the top of the heater.

So, this may be relocated onto the deck.

I wonder if I built the deck strong enough to hold a ton in one spot....

I reckon your coil is not tight enuff and your are not making enuff heat. And that the majority of heat you are making is not spending any time being focused on the pipe like you want it to - but escaping up your chimney. You've got some shit kinking going on on that pipe of yours eh? This is what was happening to me when i was trying to make a tighter coil by hand.
