The schiedel multi
The Schiedel Multi is a new concept in ceramic chimneys, allowing up to ten room sealed appliances to be conncected to the one chimney. The new Schiedel profiled ceramic liner enables the chimney to work effectively at low temperatures.
The Schiedel Multi is a concentric air-flue gas system consisting of a ceramic pipe to take waste gases away and a surrounding concrete shaft to deliver combustion air to the appliance.
The combustion air is drawn in through vents located near the chimney top and transported to the appliance through the angular gap in the chimney block. The waste gases are safely discharged to the outside through the central pipe created with high quality ceramic liners.
Travelling in different directions within the chimney, the heat of the waste gases is transferred to the combustion air. This means that the combustion air is pre-heated before it enters the boiler, improving efficiency of the appliance.
The appliance is connected through a concentric double pipe to the chimney system.
main features
- High quality, thin-walled, inner ceramic liners with profiled surface for durability & performance.
- Simple & efficient ceramic plug-in connections for the appliance.
- Operates under negative pressure.
- Safe water gas discharge.
- Compact design minimising the space required.
- Increases the efficiency of the appliance because the combustion air is preheated as it travels towards the appliance.
- Decentralized heating, allowing individual billing based on individual boiler energy consumption.
- A maximum of 10 appliances can be connected to the system, with one or two per floor.
Separation of the waste gas and air supply
The inlet for the combustion air is designed to be below the chimney outlet and separated from it so that the waste air and the air supply cannot mix. The combustion air is transported to the appliance through the central high quality ceramic liners.
Profiled high quality ceramic liner
The new profiled ceramic liner from Schiedel has a fully ceramic plug-in connection for the appliance. The profiled liner has been designed to function at the highest performance levesl. it is resistant to high temperatures, temperature change and acid corrosion. The profile liner is airtight and has a moisture passage value of 2g/hm².
The Multi prefabricated base
The base of the chimney is formed with a prefabricated unit comprising a cleaning door connection with overflow brake and condensate drain.
The overflow brake in the cleaning door acts asa pressure compensation opening. it reduces the pressure difference between waste gas and supply air channels, creating more regular conditions for combustion. It helps to create the conditions for good fuel efficiency and avoids unnecessary energy losses when appliances are not being used.
