Of interest to: people interested in energy conservation and professionals working in the field

We have created a theory for design and construction of residential masonry heaters based on “principle of free gas movement”. The theory has been proven successful by hundreds of different masonry heaters designed under the theory and built by our team all around the Eastern Europe. There is a patented invention that is used as a basis for design of all of our multifunctional stoves. Our masonry heaters or “stoves”, how we call them, because not all of them are the heaters, use renewable energy sources and correspond to energy conservation standards. They have a solid reputation and are at high demand in Russia and Eastern Europe. No analog stoves are described in publications anywhere in the World.

Some other significant things happened over time. A “trade school” for highly professional heater masons was set up. A system for computer based stove designing was created using adapted software. The system is used to design stoves, to draw working drawings, and for graphic design of projects. This system allows to maintain a database of existing projects, to correct drawings, coordinate and exchange designs, and coordinate projects under construction through the Internet.

Our theory allows creation of countless designs of masonry stoves. We have created designs of residential masonry stoves for various purposes and of various heat outputs. These include heaters; combined heaters-cookers-bakers; wood-burning boilers for hydronic systems; steam sauna stoves with adjustable temperature of produced hot water and option to control temperature/humidity in the room without use of electricity; Russian stoves “Teplushka”, and others. All these stoves can have an open fireplace incorporated in the stove where fireplace’s walls are heated, and the fireplace itself is a part of the stove. Such fireplace can be located on either side of the heater. Also designed and successfully built:

numerous heaters with heated benches or even a “heated bed”
two- and three-story stoves for multistory buildings that work on one chimney flue. These stoves may have various functions, including open fireplaces, hot water coils, bake ovens and other in any combinations.
Multifunctional stoves with built-in hot water heating system (coils or tanks) that is used as a back-up and preheating system in hydronic heating systems.
As an example, our stoves and stoves-boilers are successfully used for heating of buildings and churches in a big Monastery in Ganina Jama near Ekaterinburg City. Our experience tells that use of would-burning stoves-boilers has a substantial economical effect by saving energy and money on amount of fuel used. These results and multifunctionality of our system supposes its high competitiveness on the masonry heaters/stove market. We consider our system as a perspective direction in masonry stoves/heaters development.
However, all these achievements have to be proven by test results of reserch conducted by an independent laboratory. I have created “Plan of a proposed research and testing…” that can come true with your help. I invite everyone interested to participate and will greatly appreciate any help in this project that will benefit people with, possibly, the best and cleanest energy efficient heating system.
Plan of a proposed research and testing of stoves built by a “single-“ or a “double chamber” (“double bell”) design to find dependence of stoves’ thermotechnic characteristics on particular constructive solutions and materials used.
Goals of the research:
To find an optimal temperature of the exhaust gases and their optimal mix to achieve the cleanest and the most efficient combustion
To prepare recommendations on the optimal proportions of stoves’ elements.
To prepare recommendations on the optimal materials for use in construction
To create understandable graphs and formulas, to make stove construction easier
To prepare recommendations for the use of the principle of “free gas movement” in various industrial applications.
To conduct testing of different multifunctional stoves designed and built by the principle of “free gas movement”.
To collect data necessary for designing of various calorific stoves (stoves using a heat carrier to bring the heat to the required areas) and stoves-boilers (fuel: regular firewood and wood pellets).
Proposed program:
To build a stove based on a “single-chamber” design, incorporating principle of a “top burn”. The stove should be constructed the way it can be easily converted into a contraflow stove. Test both variants on different stages. Test different designs of the firebox to achieve the highest efficiency.
To build a stove of a size sufficient for installation of a hot water coil, hot water tank (a permanent “cold zone”) inside a chamber. Test it as in #1. Install different catalysts in the firebox to achieve the cleanest burn. Test as in #1.
To conduct similar testing building a firebox (or parts of the firebox) from a material with a high thermal conductivity. The goal is to achieve rapid equalizing of the firebox walls’ temperature and temperature of the gas flow to increase temperature of the gases entering the heat-exchanging chambers. Test as in #1.
Test various firebox designs during different burning cycles including “continuous burn”, “bottom burn”, “backfire”, etc. Test it as in #1.
Same as #5 but in a stove with a hot water heating coil/tank. The goal is to develop designs for various stoves-boilers using wood pellets as a fuel, to automate loading of the fuel.
Built a classifier stove. Test as in #1.
Built a classifier stove inside a “ventilation chamber”. Test it as in #1.
To build a stove with a heat accumulating mass with an automatic regulation of the heat output. Test it.
What is required:
To find a suitable laboratory.
To invite for participation an Organization working in energy conservation field and interested in building efficient boilers.
To invite for participation organizations or professionals, experienced in building and using boilers working on "“back fire" or “bottom fire” principles.
To find financing and an experienced financial manager.
