One : you are creating one of the most efficient Wood burning units ''In the World " and then letting most of the heat radiate to the outdoors,
Simply Burying your exhaust pipe in a box of sand/Thermal Mass is preferable to allowing 60% of your heat to be exhausted to the environment !
Two : The barrel is vital to achieving even the 40% of prompt heating expected off of the RMH, No barrel and all you have is a way to burn wood
efficiently, and Zero Way to provide useful Warming !
When the barrel goes on the vertical chimney must go up, This is a mandatory step that is required by the Physics of the RMHs operation, You
can not even expect to test your RMH (out of doors ) without following up the setting in place of the barrel w/o immediately erecting your vertical
chimney !
Cast your net around you, hopefully you will find someone with previous experience in RMH building in time to make and test a few conventional
designs before your july event ! For the craft !

Hi, thanks for the response. It would be good to make a thermal mass heater but I do not believe that is viable for this event. It will be out doors in a state forest, for one day. The heater needs to turn up and be removed the next day. I was looking at maximise the heat I can produce with little wood for a short time...mainly whilst a spit roast dinner is being eaten. Then removed.
However I am interested in making one for home. It will be an experiment at first and then maybe i'll look at putting one in the house or undercover seating area.
