Hi all
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!
Thanks
Kevin
