The Henley Severn 12 kW DEFRA Multifuel Stove is designed for owners seeking a powerful, high-capacity solid fuel stove capable of heating large rooms or open-plan spaces. Engineered for performance and flexibility, the Severn 12 kW stove combines robust construction and multifuel capability with compliance to modern emissions standards — making it suitable even for smoke-controlled areas. Built with a heavy-duty steel body (and cast-iron door), it is designed for long-term durability and reliable operation. Its clean-burn combustion system aims for efficient fuel use and reduced emissions. Whether burning seasoned wood or approved solid fuels, this stove promises strong, consistent heat output that can serve as a primary heating source for larger living spaces.

Key Features:

  • 12kW Heat Output: Provides robust and substantial warmth — suitable for large rooms, open-plan areas or whole-house heating support.
  • DEFRA-Approved Smoke Exempt Design: Certified for clean-burning wood combustion in smoke-controlled zones — allowing legal and responsible use in urban or rural settings. (DEFRA Smoke Exempt status helps ensure the stove meets emissions limits and combustion-air safety requirements.)
  • Multifuel Capability: Designed to burn seasoned wood as well as approved smokeless solid fuels — offering flexibility depending on fuel availability or preference.
  • Clean-Burn Combustion System: Incorporates a combustion-air design to promote efficient fuel burn, reduce emissions, and maximise heat output per fuel load.
  • Durable Steel Body with Cast-Iron/Robust Construction: Built for longevity and designed to withstand high heat loads — giving long-term reliability and stable performance.
  • Large Firebox & Generous Fuel Capacity: Sized to accommodate larger fuel loads — ideal for extended burns, longer heating periods, and reduced refuelling frequency.
  • Flexible Fuel-Use Options: Able to use approved smokeless fuels (where allowed) as well as wood — giving versatility for different fuel types and seasons.
  • Powerful Room Heating for Larger Spaces: Heat output is suitable for large living areas, open-plan homes or communal spaces — making the stove an effective primary heating source rather than just a supplementary heater.
  • Traditional Stove Aesthetic with Practical Function: Combines classic stove styling with modern combustion technology, blending form and function for many interior styles.

Stove Glass Accidental Damage Cover

Replacing damaged stove glass is something most stove owners will be familiar with, be it by closing the door on a protruding log, over-tightening the glass retaining clips or the natural heat expansion of the door, chances are you have had to purchase replacement glass for your wood burning stove at least once.

By adding Glowing Embers' Accidental Damage Cover, you have peace of mind that the potentially costly process of cutting and shipping a replacement glass is covered for when those accidental breakages occur.

Terms & Conditions

Glass Protection covers you for cracked or smashed stove glass for the period of time that you select. We cover you for accidental breakage for any reason for the length of time you selected but doesn't cover for any consequential loss or installation costs. Installation is usually an easy process, and our team can talk you through it. To claim against this protection, simply send us an email prior to the expiration date (either 1 or two years from the purchase date, depending upon which option you pick) with a photo clearly showing your stove with the broken glass. We may require measurements or a template from you to cut the replacement glass accurately and your provision of this when required is conditional on our fulfilment of this protection. The protection covers you for one replacement only within the set period, additional breakages (outside of breakage on delivery which will be covered free of charge) will fall outside of this protection. This only covers flat glass cut by Glowing Embers and does not cover curved or printed glass.
