The System has the following advantages over forced gas movement systems:
Principle of operation where only the cooler gases are exhausted into chimney, allowing the hotter ones to stay inside for much longer time. This increases efficiency and lengthens heat retention time. This characteristic also results in low draft requirements: draft that would be considered too weak for stoves of forced gas movement systems is sufficient for successful operation of our stoves.
Unbelievable flexibility of design, allowing creating stoves of almost any shape and size. In comparison with limited length of channels in forced movement systems, there are virtually no limitations here.
Combination of various functions in a single stove impossible in other systems. For instance, a single firebox heater with a cook top; a heater with a built-in open fireplace; a heater with a full-size heated bed and others.
A feature called "automated shut-off". In our stoves, it is not very important if the shut-off damper is closed not in time or not closed at all after fire is gone. Our stoves remain warm for a long period of time, whether in other systems, not closing a shut-off damper in time leads to a rapid heat loss up the chimney.
Successful operation of stoves connected to the existing uninsulated outside chimneys. This feature together with flexibility of design allows conversion of the existing conventional fireplaces into masonry heaters.
Substantial delay in loss of efficiency under prolonged firing conditions. In contraflow and similar designs efficiency drops significantly when the stove is "over fired" (fired for a longer than normal period of time).
Location of heat exchanging coils in multifunctional stoves and boilers outside of the firebox. Such placement maintains high combustion temperatures, thus enabling to use energy of the fuel in full.
Heating of the thermal mass rather than the heat medium (water) in the boilers and multifunctional stoves. Mass of the thermal receiver can be heated 5.5 to 6 times better than water thus considerably increasing the accumulating capability of the system.
