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 gas are cooled well below 120°C hence the maximum condensate happens in chimney. The condensate then flows along the internal wall of the pressure-tight pipe, back to the boiler for disposal. The condensate is acidic and decomposes base metals. Earlier used boiler and exhaust gas pipe material is hence not sufficiently corrosion resistant. The acid in the exhaust gas had to be neutralized through proper treatment.
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 over 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 perfect chimney kit for your condensing boiler.
