A powerful, practical stove designed for efficient heating and everyday control.
The Nestor Martin Harmony I Ecodesign stove combines robust performance with simple, precise control. Designed for burning wood or smokeless coal, this multi-fuel stove offers a generous 9kW nominal heat output, making it a strong choice for larger living spaces and open-plan areas.
Built with Nestor Martin’s reputation for quality and durability, the Harmony I is designed to deliver dependable heat, efficient combustion, and long-lasting performance. Its classic styling and practical features make it a reliable centrepiece for homes that need both warmth and functionality.
Efficient Multi-Fuel Performance
The Harmony I gives you control over the way your stove burns. Equipped with airwash control and a thermostatic damper, it allows you to manage combustion and heat output with ease, whether using seasoned wood or approved smokeless fuel.
With an efficiency rating of 76% and an A energy rating, the Harmony I is designed to make effective use of fuel while delivering strong, consistent heat.
Easier Lighting and Cleaner Burning
A direct draught slide helps heat the flue quickly, making it easier to establish the fire from cold. This supports a cleaner, quicker ignition process and helps reduce the frustration often associated with lighting a stove.
The built-in airwash system also helps keep the glass clearer by directing air across the viewing window, so you can enjoy the glow and movement of the flames.
Practical Side-Loading Door
One of the standout features of the Harmony I is its side-loading door, allowing longer logs of up to 400mm to be loaded with ease. This practical design reduces the need for frequent refuelling and can help minimise ash and debris falling onto the hearth during loading.
Ecodesign Compliant
The Harmony I is Ecodesign compliant, meeting the stove emission standards introduced in the UK in 2022. Ecodesign stoves are designed to burn more cleanly and efficiently, helping reduce emissions while still providing excellent heating performance.
