Standard Specification for Custom Tiled/Mortared Masonry Heaters (Stoves)
 N E2778

Annotation

This specification contains specifications for the dimensioning of custom tiled/mortared masonry heaters (stoves). The custom tiled/mortared masonry heaters (stoves) are individually technically calculated and constructed. This information can be used for log (cordwood) wood-fired masonry heaters that burn one fuel load per storage period with a maximum load between 10 and 40 kg and a storage period (nominal heating time) between 8 and 24 h per EN 15544.

This specification is valid for masonry heaters equipped with fireclay as interior material with an apparent density between 1750 and 2200 kg/m , a degree of porosity 18 up to 33 % by volume, and a heat conductivity from 0.65 up to 0.90 W mK (temperature range 20 to 400°C) per EN 15544.

This specification is valid for masonry heaters with sidewise combustion air supply of the combustion chamber.

This specification is not valid for masonry heaters combined with water heat exchangers for central heating or other heat-absorbing elements such as glass plates greater than 1 6 of the combustion chamber surface, open water tanks, and so forth. It is also not valid for masonry heaters combined with heating/fireplace elements in accordance with EN 13229. Furthermore, this specification is not valid for mass-produced prefabricated or partly prefabricated slow heat release appliances according to EN 15250.

The calculation method of this specification is used to establish emissions and energy efficiency when burning log wood or wood briquettes according to the manufacturer's or builder's manual.

Clearance to Combustibles - When a masonry heater is constructed according to this specification, the clearance to combustibles shall be in accordance with TRVB 105 or other appropriate standards.
