The Cast Tec Horizon 5 Wide Eco Multi-Fuel Stove combines the visual presence of a larger stove with a manageable 4.9kW nominal heat output. Its wider body and panoramic viewing window provide a generous view of the fire without increasing the heat output beyond that typically required for many standard-sized rooms.
Designed to burn both seasoned wood and suitable smokeless fuels, the Horizon 5 Wide offers 76.1% efficiency, DEFRA smoke control exemption and EcoDesign performance. It is available as either the standard freestanding model or with an optional Log Store Base.
Wide Stove With 4.9kW Output
The Horizon 5 Wide has been designed for customers who want the appearance of a larger stove without the higher heat output normally associated with a wider firebox.
Its 4.9kW nominal output makes it suitable for many standard-sized living spaces, while the 470mm wide body creates a more substantial focal point.
Panoramic Viewing Window
The wider firebox provides a generous view of the combustion chamber and flames. It also allows logs up to approximately 300mm long, giving the stove a more substantial fire display while retaining its 4.9kW rating.
Multi-Fuel Capability
An integrated multi-fuel grate allows the Horizon 5 Wide to burn seasoned wood or suitable smokeless fuels, providing flexibility depending on the preferred fuel.
Primary, Secondary And Tertiary Air
The stove incorporates several stages of combustion air to help manage the fire and support efficient burning.
- Primary Air: Controlled from the stove door
- Secondary Airwash: Helps maintain a clearer glass window
- Tertiary Air: Supports more complete combustion
DEFRA Smoke Control Exempt
The Horizon 5 Wide is DEFRA smoke control exempt, allowing wood to be burned in smoke control areas when the stove is installed and operated in accordance with the manufacturer’s requirements.
EcoDesign Compliant
The Horizon 5 Wide has been tested to meet EcoDesign requirements, combining its traditional solid-fuel format with modern combustion performance.
Top Or Rear Flue Outlet
A 125mm / 5″ flue outlet can be connected from either the top or rear of the appliance, providing flexibility when designing the flue system.
Optional Log Store Base
The Horizon 5 Wide is also available with a Log Store Base. This raises the firebox and creates an open storage area beneath the stove, giving the appliance greater height and presence.
The standard model weighs approximately 68kg, while the Log Store version weighs approximately 80kg.
Ventilation Requirement
Cast Tec’s technical specification lists an air vent as required for the Horizon 5 Wide. Ventilation should be confirmed as part of the installation and in accordance with the manufacturer’s instructions and current Building Regulations.
