Experience the benefits of our hinged door fireplace design, where functionality and aesthetics come together seamlessly.

Enhance your Optimum fireplace with accumulation stones (Optional)

 

Extended heat distribution

The accumulation stone is not just an optional feature; it's an enhancement that improves the way your fireplace distributes heat. By absorbing and storing the excess heat generated during a fire, it gradually releases it into the room, ensuring a more even and consistent temperature for an extended time. This means less reliance on other heating sources.

Cost-effective heating

The use of accumulation stone can lead to cost savings on your heating bills. The heat retained in the stone allows you to enjoy warmth well after the fire has gone out, reducing the need for additional wood.

Hinged door system

Our fireplace features a hinged door for effortless access. This secure mechanism ensures a smooth and easy door-opening experience.

Space Efficiency

The hinged door design is notably practical for spaces with limited vertical clearance. Unlike retractable door systems, it doesn't require additional height for the door to slide up. This makes it an excellent choice for rooms with lower ceilings.

Accessibility

The hinged door allows for a wide and unobstructed view of the fire, making it easy to add woodadjust the flames, or clean the interior. It provides a user-friendly experience that is both convenient and visually pleasing.

Door handle

The door handle is an integral part of the device and is available in various colors from our range: Black, Terracotta, and Maple Gold.

Fresh air supply

The fresh air supply can be adjusted using the supplied handle. Maximum air supply for combustion is achieved when the slidable handle is moved completely to the right.
It is best to slide the lever completely to the right when lighting the fire. Once the kindling wood is nicely ignited after 10 to 15 minutes, the air regulator can be put back in the middle position.

If the handle is in the middle position, the fireplace burns at nominal heat output. In this position, the combustion and efficiency are best when the chimney is drawing at minimum 12 Pascal.

Moving the handle further to the left reduces the air supply and this decreases the output of the fireplace. When you slide the handle further to the left from the middle position, this reduces the air supply in the fireplace. Once the air supply is in the fully left position, the fire in the fireplace will be extinguished.

Enhanced Heating Options

The possibility of choosing between a ceramic heating bottom or a 20mm solid steel bottom with a cast iron grate and ash pan is available for the Optimum.

The ceramic material used as the heating bottom is renowned for its exceptional thermal properties. This option is perfect for heat retention and a consistent, extended heating experience. Moreover, the ceramic is an organic material, emphasizing its natural appeal.

On the other hand, the 20mm solid steel bottom, complete with a cast iron grate and ash pan, offers a distinct set of advantages. The minimalistic steel construction provides durability and strength, ensuring it can withstand high temperatures and the rigors of daily use like the ceramic bottom. The grate and ash pan are thoughtfully designed to facilitate convenient ash removal. This option is ideal for those who favor a more minimalistic fireplace setup combined with effortless maintenance and cleaning.

Custom convection slots for enhanced fireplace efficiency

Upgrade your fireplace with a convection slot—designed to improve heat distribution and energy efficiency by circulating warm air evenly throughout your space. This innovative feature enhances comfort, reduces heating costs, and ensures a safer, more effective fireplace experience.

Our convection slots are available in three stunning colors BlackTerracotta or Maple Gold and can be customized to your exact measurements, ensuring a perfect fit for any fireplace design. Whether for new installations or retrofits, this solution combines functionality with style.

Flue Pipe Reducer

Metalfire offers the solution for seamlessly adjusting your flue pipe from Ø180mm to Ø150mm. This optional accessory allows you to achieve a perfect fit for your unique installation requirements. Ensure your system is tailored to your needs with this versatile addition.

Positioning the appliance 

The fireplace is equipped with 4 adjustable support feet
The height of the support feet can be adjusted both inside and outside the fireplace.

If the highest position of the support feet is not sufficient, a supporting structure must be built on which the fireplace can be placed. This must be sufficiently solid and stable to support the weight of the stove

Fuel: Wood 

To obtain optimal combustion, the moisture content of the wood should be no more than 15% If this is not the case, the glass will quickly become soiled and appliance will be less efficient. To achieve this moisture content, the wood must be dried for two to three years in a dry well-ventilated place. The most suitable wood types are beechoak and birch.

Each of our fireplaces has an optimal wood load: for Optimum models we recommend 25 cm logs. The use of resinous wood types, chipboard, laminate, treated wood or accelerants is strongly discouraged, as it produces sparks and a short burning time. It also harms your fireplace and the environment. Please consult our manual for detailed instructions per type of fireplace.

By reducing the emissions of fine particles and other air pollutants, we help to improve the comfort and environment of the end user.

Responsible wood burning  

Wood heating can only be economical and ecological if it is used in the right conditions! Choice of equipment, choice of wood, feeding the stove, maintenance... With these conditions you can reduce the emission of fine particles and other air pollutants, but also increase the efficiency of your combustion.

Interior finishing

Original | Triangle | Round

Like the 'Original' vertical cast-iron slats, the 'Triangle' and 'Round' versions exude minimalism. The 'Triangle' cast-iron slats represent a more angular approach to the inside of the fireplace, while the 'Round' cast-iron slats - based on a design by Belgian architect Benoit Viaene - are characterised by gentle curves.

The common denominator is the elegant rhythm in both surfaces, which creates an interesting dialogue with the warm light of the fire. The sleek and refined finish of the 'Original', 'Triangle' and 'Round' versions fits perfectly into any interior (in any fireplace) and is also a real eye-catcher, whether the fire is burning or not.

The common denominator is the elegant rhythm in both surfaces, which creates an interesting dialogue with the warm light of the fire.

Ceramic concrete look

In our pursuit of offering you the most diverse and adaptable choices, we like to introduce a captivating variant of the Optimum interior finishes. In addition to its exceptional cast iron design, the Optimum is available in 'Ceramic' material with a striking concrete look.

Elevate your fireplace aesthetics

The 'Ceramic' material with a concrete look brings a modern, industrial charm to your space, while still maintaining the high-performance features that define that material. This new variant is designed to not only keep you warm and cozy but also to serve as a stylish centerpiece in your home.

Interior finishing colours

Black | Terracotta 

Though the Standard 'Black' lacquer already offers the most beautiful timeless base for any fireplace, Metalfire add a new color to their cast iron finishes for closed wood-fires.

As the name predicts, 'Terracotta' is a vivid orange-red lacquer, reminiscent of typical Mediterranean sceneries. A constant reminder of the sunniest of settings and a welcome pop of color during darker days. Whenever, wherever, 'Terracotta' oozes pure warmth and abundance.

Terracotta, its visual power is undeniable, stunning by day and magical by night when the fire is lit.

Exterior finishing colours

Black | Terracotta | Maple gold

Our commitment to personalization extends to the finishing frames and handles for the Optimum. You can select from 'Black', 'Terracotta' or 'Maple gold' for the 10mm finishing frame and for the handle. This level of customization ensures that your fireplace is not just a source of warmth but also a reflection of your unique preferences and has the aesthetics to seamlessly integrate with your interior design.

The expanded color selection is available as well as for finishing frames and customized concepts, offering even more ways to tailor the design to individual tastes.

Customization

Finishing frame | Door handle

The standard Metalfire finishing frame is 10 mm thick and is available in lacquered 'Black', 'Terracotta', or 'Maple gold', allowing you to choose a finish that best complements your interior design. The handle is also available in three colours: Black, Terracotta or Maple Gold.

 

But the customization doesn't stop there. Our commitment to personalized aesthetics extends to the door handle as well. You have the option to customize the door handle in the same colors as the finishing frame, providing the opportunity to create a harmonious look that matches either the interior finish or the frame, adding that perfect finishing touch to your fireplace.

MADE-TO-MEASURE 

Belgian craftsmanship is Metalfire's credo. Every day, the vision of extraordinarily unique fireplaces is put into practice by the expert hands of skilled craftsmen. It creates a unique appeal that by automated production processes simply cannot be imitated.

Metalfire's no limits attitude allows ample possibilities in customization, finishing frames, fireplace concepts, wood storages and extensions. Customization supports the creative vision of the architect or interior designer, all within the imposed standards.

Finishing frames (thickness 10 mm) and concepts are available in all our standard finishing colours. For technical support please contact support@metalfire.eu

You want it, we create it. Metalfire's motivation to blend into the architecture and the interior of the home as a whole, is what sets us apart from the masses.
