It has been too warm in MO lately to run my
rocket stove heater, but I still want to cash in on heating my
water with it. To do this, I turned the central heat blower off and left the pump running. By using a small fire fueled with brush from
trees I cut down, I can keep the water nice and hot without boiling. Here's a quick
video I did on it:
It also enables me to use nearly all of a tree, the large
wood in the cold weather to heat the house and water. The brush is used in the warm weather to heat just the water.
