Manually fed solid fuel hot water boiler for larger central heating systems and for fuel with caloric value greater than 15000 KJ/kg;
Boiler is constructed according to the EN 303-5. Steel materials used apply to EN 10025, EN 10028-2, EN 10120 i EN 10088-2.
The whole boiler is insulated with appropriate mineral wool protection and its door with vermiculite.
Three pass construction (horizontal passes) ensures quality combustion process. However, TKH is a solution between TKK3 max and CTK models: while TKK3 max has no tubulators at all, and CTK has both second and third pass in form of tubulators, TKH has only a third pass in tubulator form. Therefore efficiency of this boiler lies between TKK3 and CTK.
In order to allow constant and most efficient working circle, use of an additional tank AT (heat accumulator) is strongly recommended.
Boiler is easy to clean with included cleaning kit. Boiler has a thermometer included as well.
Draught regulator is not included.
