Thanks to its unique automatic heat-up procedure, the SilvaWIN Klassik heats particularly easily and quickly. After just a few minutes, the boiler burns stably and you can relax and leave it to carry on heating by itself.
The integrated carbonisation gas extraction system ensures clean, smoke-free refueling. With its vacuum fan, which is installed as standard, it ensures the best possible combustion with optimum energy use.
When it comes to heating up, the SilvaWIN Klassik is one of the fastest boilers around. However, it takes a particularly long time for the wood to burn fully. Behind the compact design lies a large filling chamber, which allows you to enjoy long heating periods before the next refueling

The SilvaWIN Klassik (9.7 – 24.6 kW) looks small and compact from the outside, but when it gets going, it shows its real strength. With its unique standard fittings and the system components which are optimally tuned to each other, the SilvaWIN Klassik is particularly reliable and safe to operate.

You're cost-conscious and ahead of your time. You want to heat independently and place great value on reliability and comfort. Then the FKU is the perfect heating solution to meet your needs. Decades of experience in manufacturing natural draught boilers have been optimised and implemented in the FKU.
