Vaillant 80/125PP

Heating, cooling and ventilation

The Vaillant 80/125PP is a flue gas discharge set used with condensing boilers, allowing exhaust gases and intake air to be ducted safely through a wall or roof. It is a concentric flue system with an outer diameter around 125mm carrying an inner 80mm pipe, matched to Vaillant's ecoTEC and similar boiler ranges. Such kits are supplied as accessories rather than standalone appliances, used by installers to complete the flue run according to length and routing needs.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Check that all components are present and undamaged, including seals and terminals, and confirm compatibility with the specific boiler model it will be fitted to.
