Stropuva S7-7kw
When firewood is loaded, a single load can burn up to 30 hours.
A single load of sawdust briquettes can burn up to 4 days.
Solid fuel: firewood, timber waste, sawdust briquettes, wood chips
Combustion duration of solid fuel load depends on its quality of fuel, outdoor and indoor temperature, thermal resistance, and other factors.
Recommended moisture ≤30%*

Power depends on the quality of fuel, heating needs for house, chimney draught.
** The boiler output is chosen according to a heating area. E.g., solid fuel is burning the whole day (20-24 hours) in the solid fuel boiler Stropuva S20 in the 200 m² building whereas the firewood is burning almost 2 days (35-40 hours) in the solid fuel boiler Stropuva S40 in the house of the same area. A solid fuel boiler Stropuva S10 also can be used but the building will warms up slowly and the boiler would have to be loaded 2-3 times a day.
*** Combustion duration depends on the quality of fuel, outdoor and indoor temperature, thermal resistance, the power of boiler, and the way recommendations of user guide are complied (boiler installation, heated water stream, water temperature maintenance).
