Silesia SK5169 chimney inserts with bent window

SK5169 Silesia body with bent window
The core element of the structure of the Silesia chimney insert is the furnace chamber. Most advanced welding technologies were utilised in manufacture. Furthermore, the chamber interior has been covered with fire resistant ceramics - Rath Inc grog, which offers both protection and good looks. The Silesia chimney insert's door is glazed with large fire resistant glass sheet. Offer a perfect view on blazing wood offers and easy access to the combustion chamber . Push the door handle to lock it. The door also feature an automatic closing mechanism. The solution offers maximum safety of operation. You can install the door to open either left or right.

Air inlet control is located below the doors. Air is sucked to the chamber by inlets near the bottom and top edges of the door which generates air flow preventing soot plaque deposits on the glass. Air influx is controlled by the knob on the regulator. Main air supply comes with the 124mm inlets placed on the sides. The vermiculite deflector in the upper part of the chimney insert provides for more efficient burning. The top of the insert features a 400 mm opening where the heat exchange can be connected. Hot exhaust is transferred to the module set on the top of the insert. From there, the exhaust goes to the heat exchange, one of many types available. After release of heat, exhaust go to the chimney by a  flue collar.

KM12 convection module
Separation of the combustion process from heat exchange facilitated construction of a chimney which gains top efficiency parameters while preserves its front window clean for long time. Large base area enables quick buildup of large amount of hot air. |Direct impact of burning if the combustion chamber heats the body of the chimney while the exhaust gas heat the convection module set on top of the insert. Next, the room air is drawn to the chamber around the chimney insert with the inlets at the bottom part. It is heated there with the body and the on top heat exchange. Then, heated air returns to the room through the grid above the chimney. It can be conveyed to other rooms with a heat air distribution system. The chimney also radiates heat through the front window. The SILESIA KM chimneys with heat exchange report one of the highest heating efficiency in the market, exceeding 77%.
SILESIA KM heat up quickly and soon provide large amount of hot air. Convection system offers an efficient solution for large houses with considerable heating demand.

WM12 water module
Silesia chimney insert with a water module offers additional functionality of a central heating boiler. It can be used as the only heat source or operate with other boilers fuelled with gas, oil solid fuels or electric heaters. Hot exhaust gas go to the water module where heat is released in a water heat exchange. Chimney insert with water module can heat central heating water or the consumption water. Apart from that, good portion of heat is radiated through the window - no difference from convection chimney.

Design of the water module facilitates high heat output of small dimensions device. Central heating pipework can be connected to the module through outlet taps located on the front part of the module. Also the coils preventing overheating of the chimney can be connected there. The connection pipes for the central heating pipework end with female thread, while the coils is connected with male thread. Also the female outlets are ready for sensors attachment. The cooling coil safeguards the heat exchange and the entire system against overheating, transferring the excessive heat to the water in the the home water circuits. The coil activates opening a thermo-couple vent, once the safe operation temperature is exceeded.
The coil is designed for excess heat transfer only!

What fouls the window glass?
You want to have your window clean as the chimneys are bought because you want to see the fire. Dirty window takes off most of pleasure, discourage people from lighting fire and converts the chimney to obstacle in the living room. This is a setback shared by good part of the systems offered in the market. What makes the glass dirty? One of the reasons is quality of fuel: damp wood and softwood. This however depends on the user. What does not depend on him, is the burner construction facilitating considerable CO emission. Therefore it is good to check the CO output before purchase. The standards request the manufacturer to disclose the CO emissions reported in testing. You should seek for system featuring CO emission below 0,15%. But many inserts now in the market output as much as 0,3 or even 0,4 % of CO. So check it unless you want to have obscured view after 10 minutes of burning
