A floor-standing single-circuit boiler that uses wood as an energy source — this is what primarily distinguishes the STROPUVA S20 model from a more universal modification with the S20 U index in the name, which can also use wood waste, coal, sawdust and peat briquettes. The useful power of the device is 20 kW, the firebox can hold 50 kg of firewood at a time, and the average operating time of the boiler at one load is 31 hours. The excellent efficiency index deserves special attention, which, according to the manufacturer, is 91.6%. Specifically, this modification is intended for use in rooms up to 150 m2.

The birthplace of the STROPUVA S20 solid fuel boiler is Lithuania. It served as a role model for many east european-made heating devices, while in terms of efficiency (about 91.6%), the S20 model is still head and shoulders above its peers.

know-how

The secret of the high efficiency of the boiler lies in the know-how of fuel combustion: it is ignited and burns in the surface layer, and not from below, as in traditional solid fuel models. This method of combustion is implemented due to the telescopic distribution of air — as the fuel burns out, the flame centre gradually shifts down.

Long burning

Structurally, STROPUVA S20 consists of two steel cylinders (one inside the other), between which there is a coolant. One load of firewood into the firebox of the model (up to 50 kg at a time) is enough for a 30-hour marathon of their burning. The boiler maintains the set coolant temperature by changing the air supply and, accordingly, the intensity of fuel combustion using a bimetallic draft regulator.

unpretentiousness

With a power of 20 kW, the model will fit for heating rooms with a total area of 100 to 200 m². It will be necessary to clean it from ashes less than twice a month, in addition, the boiler was originally designed to work without the use of electricity. The manufacturer's model range also includes the STROPUVA S20 U boiler — a universal modification of the device that can use wood chips, coal, anthracite, sawdust and peat briquettes as fuel.

Additional features boiler STROPUVA S20:
  • Loading opening dimensions — 260x220 mm
  • The volume of the firebox is 350 L (50 kg of firewood can fit)
  • Boiler operation at one load — 31 hours
Model modification:
  • Model S20 — energy source: firewood, wood waste
  • Model S20 U(station wagon) — energy source: firewood, wood waste, coal, sawdust and peat briquettes
