KARMEK wood pellets are practical and functional, without neglecting their aesthetic aspect. Their strength lies in their high heat output which is possible due to the fact that the exchanger is positioned inside the flues. The cold air taken from the outside environment passes through the piped heat exchanger and then re-emitted at a temperature of around 100 degrees. The Marylin and Ambra models have both an upper and lower heat output; this guarantees that the temperature from the floor to the ceiling is balanced. Furthermore, based on the customer's choice, the lower output can also be used for piping, therefore making it possible to heat multiple rooms in a house. Instead, the KK Idro model is suitable for radiator systems, guaranteeing balanced heat all over house.
