Chesneys Beaumont 4WS MK3 Wood Burning Stove
The Chesneys Beaumont 4WS MK3 Wood Burning Stove combines elegant traditional styling with efficient modern combustion technology, making it a practical choice for homeowners who want both visual appeal and reliable heating performance. This compact stove delivers the atmosphere of a real wood fire while still meeting the demands of modern living.
Its compact size makes it especially suitable for smaller and medium-sized living areas, snug rooms, fireplace renovations, and homes where space remains limited. At the same time, the Beaumont range features a softer and more refined appearance that complements both period properties and contemporary interiors.
Because Chesneys designed the Beaumont 4WS MK3 as a DEFRA-exempt model, homeowners can legally use it within smoke control areas throughout the UK. This gives homeowners greater flexibility when installing a wood-burning stove in urban locations.
Clean-Burning Performance for Smoke Control Areas
The Beaumont 4WS MK3 delivers the benefits of a traditional wood-burning stove while producing significantly lower emissions.
Its DEFRA exemption allows homeowners in smoke control areas to enjoy the warmth and character of a real fire without facing the restrictions applied to non-compliant stoves. In addition, the stove achieves impressive emissions performance, with smoke output rated at just 1 gram per hour.
This figure sits well below the permitted DEFRA threshold and highlights the efficiency of the stove’s combustion system. As a result, homeowners looking for a cleaner heating solution can enjoy both environmental performance and everyday practicality.
Heating Performance and Fuel Efficiency
The Beaumont 4WS MK3 provides comfortable and dependable room heating for smaller and medium-sized spaces.
The stove delivers a nominal heat output of 4.4kW and operates within a working heat range between 2.5kW and 5kW. This allows homeowners to maintain consistent warmth throughout the day while also controlling heat levels more effectively.
The stove works well as a primary heat source in compact rooms or as additional heating within larger homes. It also achieves a high net efficiency rating of 85.2%, helping homeowners maximise usable heat from the fuel they burn while reducing unnecessary waste.
Because of this strong efficiency rating, the Beaumont 4WS MK3 balances heating performance with lower fuel consumption.
Flexible Installation Possibilities
The Beaumont 4WS MK3 features a compact footprint that offers greater flexibility during installation planning.
The stove measures 456mm wide, 552mm high, and 317mm deep, allowing it to fit comfortably into a variety of fireplace openings and room layouts. Homeowners can also add an optional heat shield when additional protection becomes necessary.
Standard rear distance to combustible materials measures 200mm. However, the optional heat shield reduces this distance to 100mm. When homeowners combine the stove with an insulated flue system, they can reduce the rear clearance even further to 50mm.
These installation options make the stove particularly useful for homes where available space remains more restricted.
Professional installation helps homeowners achieve safe operation, regulatory compliance, and reliable long-term performance. Careful planning also helps position the stove effectively within the room layout.
Traditional Styling with Modern Practicality
The Chesneys Beaumont 4WS MK3 retains the classic character expected from a traditional stove while incorporating modern engineering that improves efficiency and reduces emissions.
Its balanced proportions and refined appearance allow it to sit naturally within a wide range of interiors. For example, it works equally well in period homes with original fireplace features and in modern spaces that need additional warmth and character.
Overall, the Beaumont 4WS MK3 offers an excellent combination of style, efficiency, and practical heating performance for modern homes.
