Good Book for Do It Yourself Types,
Verified Purchase(What's this?)
This review is from: Rocket Mass Heaters: Superefficient Woodstoves YOU Can Build (Paperback)
The Rocket heater is an interesting concept, fairly well presented in the book.
This type of heater is not for everyone, and the authors describe the pros and cons of this type of heater well enough that one should be able to decide if this type heater is useful for their application.
This is very much a handbook for a work in progress-- a do it yourselfer can typically build one of these heaters, but don't try to hand off construction to the typical hired mason, it is not that type of book.
The illustrations and pictures adequately present the concepts-- one illustration that would be helpful to add is a 3D projection drawing, which would work better than parsing several 2D drawings to get the feel of the in-the-round barrel contra flow of the exhaust smoke traveling up from the inner stack and down the sides.
I'd like to build a Rocket mass heater... but the people I live with don't seem to like a work in progress 55 gallon drum rocket stove for heating a house (the heater installed instead will be a conventional Finnish mass masonry heater, at considerably more expense).
Overall the book is a worthwhile text on a heater option that may work for those who are willing and able to build their own. Even if you don't build one, you learn something new-- always a good thing.
