Summary
part 3 of a 3 part podcast
Paul and Peter continue discussing RMHs and heating.
Paul describes the cob hat fitted to the 4 inch RMH in the Love Shack. The Shack lost significant temperature overnight; leading to the modification. Adding the cob hat above the barrel harvested a lot more heat. However, the 4 inch RMH has other issues which make it problematic in use.
They talk about the cook stove in Allerton Abbey. Peter says this is the only double shoebox still remaining as he had issues with the design, but this one works although it has gone through several doors. Peter says it's a very powerful core and so it's difficult to tame it.
Paul recalls the rocket mass heater jamborees, where they made good progress with designs but it always cost a lot to run. Paul would like to run another jamboree; Peter remarks that he's almost 80 now and might not be able to get there. Peter has an idea for a development of a J tube which could be tried out if there was a jamboree.
Ben Falk joins in with some questions. He points out that with a suitable wood stove you can also do all your cooking and heat domestic hot water while heating your home. Ben has been using a woodstove to heat his home and hot water and to cook, and typically uses about 2 cords of wood. Peter says he's often seen people change from a conventional stove to a RMH and use one third of the fuel. Paul states that one year he measured the wood used very carefully and consumed 0.6 cords, but it's worth noting that is only for heating, not hot water and cooking.
Peter's opinion is that the 10% of the fuel use is not all that common. He says mostly 30% is a good target. There are good discussions to have about cooking and water heating.
