Beauty and technologySTILE, the new hydronic space heater available in the powers of 16 and 27 kW opens a new course in the market of the “Home furnishing Warm” with performances of a true boiler and the elegance of the space heaters for inside installation.

The hydronic space heaters STILE, completely automatic and programmable, are true generators of heating with which it is possible to heat the water for the C.H. system and for domestic use (STILE 27). STILE is born from the designing centre of Unical, a leader company in the construction of boilers. Particular attention has been set to the search of the maximum efficiency, large autonomy and maintenance reduction.

The outer casing is the successful integration among: sides panels in steel, enamelled with thermo-resistant powders, divided in three panels easily removable, to access the inside components and the façade with crystal inserts 4 mm thick, that allows the vision of the flame. The access to the reservoir, for the recharges of the pellet, is facilitated thanks to the upper cover. The content of the reservoir:

STILE 16 = 28 kgSTILE 27 = 60 kg

together with the considerable reduction of the consumptions, allows a notable autonomy of operation.

Autonomy and efficienciesWith a global efficiency up to 90%, together with the maximum autonomy of operation, it will be possible to appreciate the notable level of performance offered by STILE. Besides it is to appreciate The project, finalized to the containment of the dimensions of the pellet reservoir, guarantees an exceptional duration at continuous operation:

STILE 16 up to 19 hours according to the requested temperature

STILE 27 up to ca. 36 hours according to the requested temperature

In the normal use, that foresees startings and standstills, the operation with modulating system will prolong notably the duration of the fuel.

The pelletThe pellet is a natural fuel that has been submitted exclusively to a mechanical treatment for its production (EN 14961-2) and that offers important advantages:

Economic, ca. 30% less expensive than the fuels of fossil origin

Effortless use comfortable small bags or, for large consumptions, stocking in silo

High calorific value 4,1÷5,0 kWh/kg that can vary according its composition (wood essence)

Small residue of ashes

Highly ecological, it recovers the wastes of the working of the wood, conveniently cleaned and dried, compacted at high pressure to form small cylinders, 10 to 30 mm long and with 6 to 8 mm diameter.

Technology and design

Structure in carbon steel 5 mm thick

Vertical water pipes type heat exchanger

Combustion circuit with forced modulating ventilation

Burner constituted by the original crucible with grate in stainless steel AISI 310 S.

Operating systemThe flame is developed in the steel combustion chamber; the produced heat frontally licks up the heat exchanger and then, coming down, crosses the special rear “pockets” completing the circuit. Subsequently, the fan sucks the exhausted smokes carrying them to the chimney. This system of room sealed forced draught with recovery of the smokes temperature maintains unchanged the combustion values for a global efficiency of 90%.

The ignition system, activates an incandescence resistance, making the ignition fully automatic also with pellet of not good quality.

Through the temperature sensor and the programmed microprocessor, the quantity of pellet, necessary to satisfy the needs of the heat, is automatically “dosed” thanks to the motorized feeding screw.

The control’s equipment adjusts the speed of the fan for the combustive air with electronic modulation. As the temperature approaches the planned values, the fan speed, and therefore the supplied power, is automatically reduced to the next lower level (among the 5 available levels), to assure the best combustion, the optimization of the consumptions and, accordingly, the high performance of the appliance.

Technology and design

Double controlled combustion that assures a high efficiency thanks to the injection of primary and secondary air in the crucible.

Burner constituted by the original crucible with grate in stainless steel AISI 310 S.

Refined electronics.

System of operationThe elevated output derives from the double thermal exchange technology. To facilitate the combustion and the reduction of the pressure losses of the hydraulic circuit it has been adopted a smoke pipes structure.

Insofar, the warm gases produced in the combustion

chamber, with a run at inverted “U”, they lick up first frontally the heat exchanger and then, crossing the smoke pipes, its rear part, guaranteeing the elevated efficiency of 85%. The smoke pipes are endowed with helicoidal springs that have the double function, of turbulators and cleaning scrapers, through a practical shacking mechanism.

The down stream fan, develops the double function of air suction and smokes evacuation.

As the temperature approaches the planned values, the fan speed, and therefore the supplied power, is automatically reduced to the next lower level (among the 5 available levels), to assure the best combustion, the optimization of the consumptions and, accordingly, the high performance of the appliance.

The operation management is completely automatic through the pre-adjusted parameters.

(1) The production of A.C.S. depends on the operation of the C.H. pump; this is inhibited up to the attainment of the water temperature, in the appliance, of 40°C. Over this threshold it is necessary to consider the necessary time so that the water’s temperature in the appliance reaches such a degree to allow the heat exchange through the plates heat exchanger. You must also consider a pressure loss due to the heat exchange; insofar the outlet temperature from the D.H.W. heat exchanger will be, with the appliance fully operating and with a water temperature of 80°C, at a continuous drawing of 10 litres per minute, of around 40°C with an inlet cold water of ca. 10°C.
