HWAM I 40/55 Fireplace Insert
Danish Design, Customised Framing & Dependable Everyday Heat
The HWAM I 40/55 replaces an existing insert or closes an open fireplace, bringing genuine Danish design to the job. As a result, it suits homeowners who already have a fireplace opening and want to upgrade it with a real wood-burning insert, rather than a freestanding stove. Above all, its minimalist, timeless Danish design keeps the focus on the flame, whichever frame is chosen.
This model suits homeowners with a specific opening to work with, since homeowners can order a customised frame to fit the exact measurements of the space. Consequently, it works particularly well for renovation projects or upgrades where a standard-sized unit wouldn’t fit cleanly.
Homeowners can choose the HWAM I 40/55 insert with a Classic or Modern door, in black steel, with left or right hinging and a choice of handle style. In addition, HWAM® SmartControl™ is available on this model, alongside HWAM® Autopilot™ as standard.
Classic Or Modern Door Styles On The HWAM I 40/55
The HWAM I 40/55 insert comes with two distinct door styles, so homeowners can choose the look that best suits their interior. Either way, both share the same performance and dimensions.
- Classic (I 40/55c) – a traditional framed door, adding a touch of familiar detailing to the insert’s front
- Modern (I 40/55m) – a cleaner, more glass-fronted door for a pared-back, contemporary look
Homeowners can also choose left or right door hinging, along with a choice of handle.
A Choice Of Handle Styles
The HWAM I 40/55 insert also offers a choice of handle styles, so homeowners can fine-tune the finishing details of the insert’s appearance.
- Traditional handle – a classic handle shape that suits either door style
- Discreet handle – a minimal, low-profile handle for a cleaner overall look
As a result, homeowners can match the handle style to the rest of the insert’s finish, whether that leans traditional or pared-back.
A Frame To Fit Your Fireplace
The standout feature of the HWAM I 40/55 is, above all, the range of frame options available, so it can be fitted into almost any existing opening.
- Frame for an in-built depth of 35cm – a standard frame for typical fireplace depths
- Customised frame, front part only (no sides) – for openings where only the front needs covering
- Customised frame, front part and 1 side – for openings needing one side covered
- Customised frame, front part and 2 sides – for openings needing both sides covered
As a result, homeowners replacing an existing insert or closing an open fireplace can get a genuinely tailored fit, rather than working around a fixed standard size.
Everyday Heating Performance
The HWAM I 40/55 insert delivers dependable, everyday warmth suited to typical living spaces.
With HWAM® Autopilot™, the insert offers a nominal heat output of 6.4kW. Additionally, HWAM® SmartControl™ provides a slightly more moderated 6.0kW alongside automated combustion management, giving homeowners a genuine choice between raw output and refined control. An optional fan kit also helps circulate warm air further into the room.
Autopilot & SmartControl Technology
Combustion management sits at the heart of how the HWAM I 40/55 insert 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 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 I 40/55 insert is DEFRA Exempt, HETAS approved, and EcoDesign compliant, so homeowners can feel confident they’re choosing an appliance suited to modern regulatory standards. Combined with HWAM’s established combustion technology, it offers a considered way to enjoy a genuine wood fire responsibly.
HWAM I 40/55 Installation Compatibility
The HWAM I 40/55 insert fits directly into an existing fireplace opening.
Because homeowners can order the insert with a customised frame, installers gain real flexibility when working with older or non-standard fireplace openings. Homeowners can also add an optional fan kit to help distribute warm air more effectively around the room.
A Considered And Dependable Heating Solution
Altogether, the HWAM I 40/55 insert combines Danish design, Classic or Modern door styles, a genuine choice of handles and frame sizes, dependable everyday heating, and the option of HWAM® Autopilot™ or HWAM® SmartControl™ combustion management. Ultimately, it offers a tailored way to upgrade an existing fireplace with a real wood fire.
