LARGE Rocket Stove heater to assist 190000 liters to 30 degrees
posted 8 years ago
I need a few suggestions. I have never built a rocket water heater before and i want to build one to assist my pool heater that i am using to heat a 190,000 liter fish tank.
At the moment i am pumping at 15,000 liters an hour through the pool heater which is heating the water by 2 degrees a day and i get the other 1 degree by pumping through 200meters of black hose, but i am loosing 3 degrees at night, so going no where!
I have been thinking of making a heat exchanger simular to http://milkwood.net/2011/06/14/rocket-stove-roundup/ and start by digging into the ground the flues etc leaving the clay ground to use as insulation and walls, then drop a 5mm plate over the flue until the chimney where i want to use corregated iron rivited round together, one smaller than the other and inserted into each other filled with riversand as insulation. On top of this put the exchanger with water pumping through.
Any suggestions on sizes? I have plenty wood here as i am in africa.... but that does not mean i want to burn plenty!
Have you considered a thermal blanket for nighttime use? Also if your pool is adjacent to any building with a metal roof you could run a trickle heating system simply by broadcasting water along the roof's upper surface and capturing it at the bottom. The system would have the added benefit of cooling the house or shed. If the roof is galvanized steel it might be wise to check to see how much zinc fish can tolerate. I know that they need small quantities but I have no idea what the upper limit would be.

hello i am also interested in heating a lard amount of water. I have an above ground pool that i would like to warm up earlier in the season and use in the fall. I have researched rocket stoveheaters and i have a few ideas and a few questions. A little help figuring out the most efficent way to transfer heat to a large body of water. Will look hearing any ideas on this problem.
