Use chimney for gas boiler

What you need:

• A permit from the master chimney sweep

What is required of a chimney

• First and foremost, a chimney must be designed in such a way that the combustion gases from the fireplace can be safely discharged into the open. The structural integrity also counts for safety. The chimney must not be leaking and must defy wind and weather undamaged above the roof.

• A possibility for cleaning is mandatory. It doesn't matter what type of pollution is. Then the cross-section of the smoke outlet must be in a certain proportion to the output and the type of lighting.

• After all, as the operator, you must ensure that the chimney sweep has unhindered and safe access to the chimney at all times. As a rule, a chimney that meets these requirements will be issued with a permit to operate on a gas boiler.

How to convert for the gas boiler

• If the technical parameters for your new gas boiler do not contain any information on the smoke outlet, be sure to consult the master chimney sweep. He can tell you which material in which thickness or which cross-section is to be used.

• Depending on the design of the gas boiler, insulation may be omitted. Then you only have to make sure that the flue pipe is vertical and without kinks in the middle of the old chimney. Get advice from your specialist retailer.


Buy a gas boiler - you should pay attention to this

A new gas boiler helps to save heating costs. However, not every model fits into ...

• Usually, especially with so-called condensing boilers, the flue pipe is made of plastic. The exhaust gases there have cooled down so far that they no longer cause any damage.

• If, on the other hand, you have an older gas boiler, you may have to install a stainless steel flue pipe and cover it to prevent condensation.

• There must be a control opening at the connection of the flue pipe between the thermal bath and the chimney, which enables cleaning and measurement or testing of the exhaust gases.
