Just to add..
This is for my workshop. My dogs sleep next door and i want to heat a small water tank and pipe warm water through garden hose and into a big garden hose coil embedded in their bed (an old leather couch)
Also want to pipe the rocket stove exhaust directly into the bottom of an oil barrel full of wet logs. This will be wrapped in insulation and a pipe will be connected to a chimney running up outside.
The barrel will have a removable top for loading and unloading wood as it dries (or catches fire resulting in massive property(rented) damage???)
