Large cast iron wood burning stove with classic style
The Jotul F 400 Eco is a powerful cast iron stove that brings together traditional looks and strong heating performance. It suits homeowners who want a stove with real presence, but it also delivers the efficiency and practicality expected from a modern appliance. Because of its larger firebox and broad glass window, it creates an impressive focal point while giving a generous view of the flames.
This model is well suited to larger rooms, open-plan spaces, and fireplace chambers where a bigger stove looks in proportion. In addition, the robust cast iron body stores and releases heat well, helping the room stay comfortable for longer. The overall design feels timeless, so it works beautifully in both period homes and more understated contemporary interiors.
Why this stove stands out
With a nominal heat output of 7.0kW and heating capacity of up to 150m², this stove offers strong warmth for larger living areas. It also reaches 83% efficiency, so you get excellent heat from your fuel. Clean burn technology helps support better combustion, while the ash solution makes day-to-day use easier and tidier. As a result, you get a stove that looks substantial but still feels practical to live with.
Another key advantage is flexibility. The appliance offers both top and rear flue exit options, which can help when planning around an existing chimney or a new flue arrangement. It also accepts logs up to 50cm, giving you the benefit of a larger fire and longer burn potential.
