When the firewood is loaded, a single load burns up to about 30 hours.
A single load of sawdust briquettes burns up to 4 days.
A single load of pellets burns up to 96 hours.

Solid fuel: firewood, timber waste, sawdust, straw and peat briquettes.

*Power depends on the quality of the solid fuel, heating need of the house and the chimney draught.

** The boiler output is chosen according to a heated 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).
