    Condensing boilers

    We offer you the best flue solution for any application.

    Condensing boilers

    The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply.  The exhaust gases are cooled well below 120°C hence the maximum condensate happens in the flue system chimney. The condensate then flows along the internal wall of the pressure-tight pipe, back to the boiler for drain points for disposal. The condensate is acidic and decomposes base metals, which is why AISI 316L materials is specified for these types of applications as other materials are not sufficiently corrosion resistant. The acid in the exhaust gas has to be neutralized through proper treatment.

     

    Due to the low temperature, the exhaust gas in the condensing boilers cannot escape through the natural chimney draft, Therefore, a blower pushes the exhaust gas through the pipes with a maximum pressure of 200 Pascal. The exhaust pipe must be such that it is suitable for positive pressure and at the same time not let the condensate or exhaust gas escape.

     

    Jeremias offers corrosion resistant exhaust systems made of stainless steel and polypropylene as pressure tight exhaust solutions for condensing boilers. Depending on the circumstances and planned air supply you can select the preferred chimney system for your condensing appliance.

     

    All the parts of the condensing flue systems of Jeremias are FULLY WELDED, no leaks, no problems.
