Stropuva S20
Katilas Stropuva s20 Kūrenant malkomis, medienos atliekomis  (viena įkrova) dega apie 30 valandų. Naudojamas kuras: malkos, medienos atliekos. Rekomenduojamas kuro drėgnumas iki 30%*. Stropuva s 20, tai unikalus katilas kuris pasižymi ypatingu degimo procesu ir yra ilgaamžis.

When the firewood or timber waste is loaded, one load burns about 30 hours.

Solid fuel: firewood, timber waste.

 

malkos

Recommended moisture ≤30%*

Combustion duration of solid fuel load depends on its quality of fuel, outdoor and indoor temperature, thermal resistance, and other factors.

Solid fuel: firewood, timber waste. 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).
