I have purchaced 3 propane tanks from the scrap yard and wanto make a water hot water heater out of it and use the rest of the energy for a cook top and forced air heater.
Take a look at my Phot and tell me what you think Before I start welding. Thanks

If it were me. I would use a copper coil around the stove to heat the water and pump it into a storage tank and or use a separate water tank, Not part of the actual stove.
Just my opinion. Cold water in the Very Bottom? If you do it may go right in where the sediment will settle?

Good Luck, I will follow your progress. Hope it works well for you.

shouldnt be too much sediment water fitered before entering tank.Gravity fed from 2 x 350 gal water storage tanks, water too tanks coming from a well source pumped in by 12v Rv water pump to fill upper resivior tank.
I have thought about the copper and actually designed it in my earthship forum but I have a wood burning cookstove I bought for cooking and heating heating purposes. I wanted this unit outdoors and thought about venting into green house for temp regul. and Co2 is a plants best friend. wanted to use as much enery as possible from one burn.
Does the concept seem feesable?

don't vent into a greenhouse. there's more than just carbon dioxide in that exhaust, and some of it can be very nasty when concentrated in a greenhouse. extra carbon dioxide is only good for plants while photosynthesis is going on (during the day), unless they're CAM plants, then they want carbon dioxide at night and not during the day. too much carbon dioxide is also a serious problem for plants (and just about any living thing).

on the water heater: placing a water jacket around the burn chamber will prevent any hope of a clean or complete burn. I think your design would work, but it would put out extremely dirty exhaust and it wouldn't be very efficient.

maybe I'm just dull and not reading your picture well, but where's the gasification going on? there's a chance I'm totally misunderstanding the whole thing, in which case I should be disregarded. from your picture, it looks like you'll be blowing into the exhaust with a fan, which would be working against the draft. what am I missing?

Look to left side of the schematic. Shows gasification chamber. here are 3 cylinders Burn in center,Gasif.Chamber 2, and water Chamber in blue. I assumed it would raise the temp. in the greenouse and the Co2 would help the plants.The exaust coming out of these stoves seems to be pretty Clean, though I don't know that much about it, I have just started to build a larger scal model.The smaller version I made with a paint can and some stove pipe seemed to be relativly smokeless after it got lit. Like I said I certainly am no expert thats why I look for help and insperation from those who are actually doing it.
Thanks so much for the feedback.Take another look at it and see what you think.
Thanks

got it. if you're getting a clean and complete burn, the exhaust is pretty clean, but there's still a lot of stuff in there that can be really nasty. that includes the carbon dioxide.

I think the water jacket idea could work, but it should be isolated from the burn chamber because you want that part (burn chamber) to be really hot for complete combustion.
