Now I am not here to argue what the word efficiency means, I am simply talking about capturing 100% of whatever heat is generated through combustion such that the exhaust is cooled down below average room temperature before departing.
Here is how simple it can be.
Use a blower fan to produce a forced draft and draw your exhaust through a series of heat exchangers (could be as simple as 55 gallon steel drums filled with brick pieces or large gravel). Each “container” would be filled with smaller sized pieces and the last one or two would be filled with sand.
