HWAM 4540 Wood Burning Stove

Danish Design, Natural Stone Cladding & Intelligent Combustion Control

The HWAM 4540 stove takes HWAM’s tall, sculptural silhouette a step further with the option of natural stone cladding. As a result, it suits homeowners who want the stove to feel like a genuine material statement, not just a steel appliance. Its raised proportions lift the firebox closer to eye level, so the flame becomes easy to enjoy from a seated position.

This model suits homes where texture and material matter as much as form. Consequently, it works particularly well in interiors built around natural materials, stone, timber, or warm neutral palettes, where the cladding can echo the wider scheme.

Homeowners can choose the HWAM 4540 stove with a Classic or Modern door, in either steel or natural stone cladding. In addition, HWAM® SmartControl™ is available as an internal fitting on this model, so homeowners wanting the most advanced combustion control can specify it from the outset.

Classic Or Modern Door Styles On The HWAM 4540

The HWAM 4540 stove comes with two distinct door styles, so homeowners can choose the look that best suits their interior.

• Classic (4540c) – a traditional framed door, adding a touch of familiar detailing to the stove’s front
• Modern (4540m) – a cleaner, more glass-fronted door for a pared-back, contemporary look

Homeowners can order either door style in black or grey steel, before choosing whether to add a cladding finish.

Steel Or Natural Stone Cladding

The standout feature of the HWAM 4540 is the choice of cladding, which changes both the look and the feel of the stove entirely.

• Steel – black or grey steel, for the cleanest and lightest option in the range
• Soapstone cladding – a dense, heat-retentive stone with a soft, tactile grey-green finish
• Natural stone cladding, Tobacco – a warm, deep brown stone finish
• Natural stone cladding, Dark Galaxy – a darker, richly textured stone finish
• Natural stone cladding, Moca Cream – a lighter, warm-toned stone finish
• Terrastone Clay cladding – a earthy, clay-toned stone finish

Because natural stone retains heat well, clad versions of the HWAM 4540 continue radiating warmth gently after the fire has died down. This makes the stove feel comfortably warm for longer, even once active combustion has finished. Every cladding option shares the same underlying stove and heating performance, so the decision is entirely about material and finish.

A Taller, More Commanding Presence

However the HWAM 4540 stove is finished, its height sets it apart from more compact models in the range.

The raised firebox improves sightlines to the flame, particularly in rooms where seating sits back from the hearth. Meanwhile, the addition of a stone cladding option gives the stove a more substantial, grounded presence, without losing the clean Scandinavian lines underneath.

Everyday Heating Performance From The HWAM 4540

The HWAM 4540 stove delivers dependable, everyday warmth for small and medium-sized living spaces.

With a nominal heat output of approximately 4.9kW, it offers a comfortable level of heat without overwhelming the room. Additionally, its convection design spreads that warmth evenly, while stone-clad versions add a gentle, longer-lasting residual heat once the fire has burned down.

Autopilot & SmartControl Technology

Combustion management sits at the heart of how the HWAM 4540 stove performs.

As standard, HWAM® Autopilot™ automatically regulates the air supply as the fire burns, so homeowners rarely need to make manual adjustments. For those who want an even more hands-off approach, HWAM® SmartControl™ is also available as an internal fitting on this model. This electronic system monitors combustion automatically and, through a companion app, lets homeowners set a room temperature and receive guidance on refuelling.

Built For Modern, Smoke-Conscious Homes

Clean-burning performance matters increasingly to homeowners, particularly those in smoke control areas.

The HWAM 4540 stove meets current DEFRA and EcoDesign expectations for wood burning appliances, so homeowners can feel confident they’re choosing a stove suited to modern regulatory standards. Combined with HWAM’s established combustion technology, it offers a considered way to enjoy a genuine wood fire responsibly.

Installation Compatibility

The HWAM 4540 stove fits a range of practical installation scenarios.

An optional external air connection lets installers draw combustion air from outside the property, which proves especially useful in newer, well-insulated, or particularly airtight homes. Furthermore, because cladding adds noticeably to the stove’s overall weight, floor loading should always be checked as part of the installation survey, particularly with heavier stone finishes.

A Stylish And Adaptable Heating Solution

Altogether, the HWAM 4540 stove combines Danish design, a tall and commanding silhouette, Classic or Modern door styles, steel or natural stone cladding, dependable everyday heating, and the option of HWAM® Autopilot™ or HWAM® SmartControl™ combustion management. Ultimately, it offers a finish suited to modern, smoke-conscious homes.
