[Stoves] High mass space heating options Re: Rocket Stove for the PLACE

[rongretlarson at comcast.net]

Alex: I believe the most appropriate answer to your final question below ( "What do you see as the advantages of combining these two approaches? " ) is one you gave yourself: ("... a desire for char ..."). 

The beauty of high mass heaters is that they mesh well with a batch process - the main (only?) drawback of char-making stoves.

Paul, 
The TLUD configuration has it's advantages and disadvantages, like any 
system. One advantage is it's steady state energy release. High mass 
heaters strive for a similar result. It seems a bit redundant to pair 
the two. Perhaps it depends on other considerations like a desire for 
char or an available particulate fuel supply. 

There are some folks doing fine work at the Masonry Heater Association. 
http://mha-net.org/ 
They have done a lot on emissions, efficiency and durability. 
They have looked into Down feed rocket configurations. 
I'm not sure if they have quantified losses between firings, or seasonal 
efficiency. 

Its a simple concept with lots of technical details. 

What do you see as the advantages of combining these two approaches?
