If the existing house-chimney is showing signs of wear and tear due to its age or no longer fulfill the requirements of a modern heating system, then a restoration of the chimney is necessary.
Usage of a modern heating system in combination with an old chimney leads to soot in the chimney as its cross section is too big for the low temperature flue. The acid condensate corrodes the chimney stones/bricks as they, too, are not made to withstand the side effects of modern flue systems.
A restoration of the chimney system is made by introduction of exhaust pipes made out of stainless steel or polypropylene from the chimney head. The choice of the flue system depends on the type of appliance, whoose sizing should be analyzed by an expert.
Depending on the application you can choose the suitable chimney kit that Jeremias has to offer.
