The document provides technical specifications for the ECKA 51/51/51h wood burning stove. It lists nominal heat power, efficiency, wood consumption, flue gas measurements, heat distribution percentages, required chimney pressure, combustion air requirements, and dimensions for the stove when operated directly connected to a chimney, with a cupola, with an adaptor, with a hot air exchanger, and with accumulation masses. Frame sizes and dimensions are also specified for building-on and cover frames.

1) The Hoxter products are available in the Austrian stove-calculation program for evaluation of firebrick accumulation systems.
2) Only a sample calculation! For accurate results is evaluation of each system in the KMS-calculation program from the Ortner company necessary.
3) Depends on accumulation period and material characteristics and its thickness. Calculated with heat emission of the radiant area ca. 500 W/m2
