Power Meets Timeless Danish Design
The most powerful cast iron stove ever crafted by Morsø, the 8643 combines robust performance with refined Scandinavian style. Designed in-house and engineered in Denmark, this modern wood fire brings exceptional heat output, ultra-low emissions, and everyday convenience into one elegant package.
With a generous firebox that accommodates logs up to 38 cm, the Morsø 8643 delivers long-lasting warmth, supported by advanced combustion technology drawn from the acclaimed 6100 and 8100 series. Despite its heating capacity, the stove’s clean lines and minimalist form create a light, timeless presence – perfect for both classic and contemporary interiors.
Crafted to endure and designed to impress, the Morsø 8643 is a future-forward fireplace that honours the legacy of traditional wood heating.

The optional Morsø 8843 external air kit allows you to connect this wood burning fireplace to exterior combustion air through the rear of the unit.
