Optimum 
Where combustion technology and interior design meet without compromise

The Optimum is a closed wood-burning fireplace with a hinged door, operating independently of the room air. It is available in several configurations, with or without storage stones or a convection chamber, allowing heat distribution to be adapted to the home and the way it is used. 

With an efficiency above 83 percent and full compliance with the Ecodesign 2022 standard, this model fits naturally into contemporary, well-insulated homes. What truly sets the Optimum apart is the extensive freedom it offers in terms of finish. 

The interior lining consists of ceramic or cast iron slats in the Original, Triangle and Round versions, each available in Black or Terracotta. The solid 10 mm steel finishing frame and the matching handle follow the same chromatic logic and can additionally be executed in Maple Gold. 

As a result, this fireplace integrates just as naturally into an understated interior as into a strongly defined architectural project.

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.

Door Handle

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

On the other hand, the 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.

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 beech, oak 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.

Interior Finishing

Original | Triangle | Round

The cast iron finishes Original, Triangle and Round share the same minimalist expression, interpreted through three distinct readings. The Original is built around vertical slats with pure, clean lines, the Triangle brings a more angular approach to the interior of the fireplace, and the Round stands out through its soft, enveloping curves.

What unites these three finishes is the elegant rhythm of their surfaces, which engages in a dialogue with the warm light of the fire. Their refined and understated treatment integrates naturally into any interior and any fireplace, forming a genuine visual focal point whether the fire is lit or not.

All finishes are available within the Optimum range and can be perfectly matched to the overall fireplace concept.

Ceramic Concrete Look

Elevate your Fireplace Aesthetics

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.

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

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.
