* Power depends on the quality of fuel and time: at the beginning of burning power output is
higher than indicated in the table, boiler puts out smoke that is hotter than 300 °C, therefore raisin
residues burn out, flue gets warmed up and draft increases (in some models, direct channel to flue
is opened). While burning, power of boiler decreases because the surface of heat dissipation
increases and draft decreases, but when a house becomes warm the power is sufficient and
additional valve is opened in order to further decrease the power of boiler.
** Power of boiler is selected according to area of premise. For example, if in Stropuva S20
solid fuel boiler built in 200 m
2
building with one load burns 24 hours, then one load of firewood in
Stropuva S40 solid fuel boiler would burn for almost 48 hours.
*** Burning duration depends on fuel quality, inner and outer temperature, thermal resistance,
boiler power, manual compliance (installation, heated water flow, water temperature maintenance).
