The MI-Fire Derwent Multifuel Stove is a compact cast iron stove designed to offer flexible fuel choice, strong efficiency and traditional stove character in a practical 5kW format. With its 80.7% efficiency, A+ energy rating, Ecodesign 2022 compliance and Smoke Control Area Exempt status, it is a strong option for customers wanting a classic multi-fuel stove with modern clean-burning credentials.
Built in full cast iron, the Derwent Multifuel Stove has the timeless look and solid feel many customers still want from a traditional stove. Cast iron gives the appliance a reassuringly robust appearance while also helping it retain and radiate heat effectively. This makes the Derwent especially appealing for homes that want a more classic fireside feel without giving up the benefits of current efficiency and emissions standards.
As a 5kW multifuel stove, the Derwent offers useful flexibility for customers who want the option to burn more than one approved fuel type. That versatility can be especially valuable depending on fuel preference, local availability or the way the stove is used day to day. At the same time, the 5kW output keeps it in one of the most practical heating categories for domestic living rooms, snug spaces and everyday fireplace settings.
One of the standout points of this model is its 80.7% efficiency, A+ energy rating and very low 11mg dust output, helping position it as one of the more efficient and cleaner-burning stoves of its size. For customers who want the ambience of a real fire alongside stronger environmental performance, this makes the Derwent a particularly compelling choice.
With both top and rear flue outlet positions, the stove offers useful installation flexibility, and it is also suitable for a 12mm hearth, which can be a real practical advantage in the right setting. At 65kg, it remains compact enough for many fireplace openings while still retaining the solid visual presence associated with cast iron construction.
