ALBERO AL11S.HD fireplace insert with a power of 11 kW
ALBERO AL11S.HD fireplace insert This steel model with a simple front glazing is designed for both modern and classic fireplaces. Its nominal power of 11 kW and a heating load range of 5.5 to 14 kW allow you to tailor the unit's operation to the building's heating needs.
The model is one of the popular ones ALBERO fireplace insert seriesIt combines a broad vision of fire, the possibility of creating a warm structure, and solutions supporting controlled and efficient wood burning.
Wide front glazing
ALBERO AL11S.HD is equipped with front glass with dimensions of 590 × 430 mmThe large glass area provides good visibility of the flames and allows you to showcase the fireplace in the central part of the living room.
The simple design of the door facilitates its use in a variety of building types. This allows the model to be used in both minimalistic designs and more complex architectural compositions.
The steel doors are made with a special profile that ensures adequate rigidity and resistance to high temperatures. At the same time, the limited number of visible elements ensures that the fire remains the focal point of the design.
Ceramic glass resistant to 800°C
The doors are equipped with heat-resistant ceramic glass suitable for operation at temperatures up to 800°CThe material allows for safe observation of flames and retains its properties during proper use of the device.
Additionally, the insert is equipped with an air curtain. Air flow is directed along the inner surface of the glass, helping to reduce the buildup of soot and other contaminants. As a result, the glass can remain clear for longer.
However, a clean glass system does not eliminate the need for periodic cleaning. Glass transparency is also influenced by wood moisture, chimney draft, fuel quality, and fireplace maintenance.
Thermal efficiency at the level of 83%
The thermal efficiency of the ALBERO AL11S.HD insert is 83%A properly designed aeration system supports stable combustion and the effective use of the energy contained in the wood.
Secondary air is supplied to the upper part of the combustion chamber. This aids in the post-combustion of gases produced during fuel combustion. As a result, the process can proceed more thoroughly and the amount of incomplete combustion products is reduced.
Declared pollen emission at 13% O2 is 38 mg/m³, while CO emissions at 13% O2 is 1243 mg/m³. Achieving the declared parameters requires the use of appropriately dry wood and the use of the device in accordance with the instructions.
11 kW power and wide operating range
The nominal power of the device is 11 kW, while the heating load ranges from 5.5 to 14 kW. This allows the combustion intensity to be adjusted depending on the current heat demand.
The selection of a fireplace insert should take into account, among other factors, the area and volume of the rooms, the building's insulation standard, the layout of the interior spaces, and the nature of the installation. Therefore, it's advisable to consult with a qualified installer before purchasing the appliance.
External air intake
The base of the insert is equipped with external air intake damperThis allows the air needed for combustion to be supplied directly from outside the building, instead of being drawn solely from the room being heated.
This solution supports controlled combustion and is particularly important in modern, well-insulated buildings. It also helps limit the impact of the device's operation on the indoor air balance.
The intake port diameter is 125 mm. The exhaust pipe diameter is 200 mm.
A fireplace insert for a house with heat recovery
The external air intake allows the AL11S.HD model to be used in buildings equipped with mechanical ventilation. the fireplace insert is adapted to houses with heat recovery.
The method of venting and connecting the insert should be considered at the design stage. This will ensure proper operating conditions for both the fireplace and the ventilation system.
Possibility of creating a warm building
The ALBERO AL11S.HD model allows you to make warm fireplace installationThe solution allows the use of carefully selected storage materials that absorb some of the heat energy and then gradually release it into the room.
The design of the unit should take into account the required active area of the ventilation grilles. For this model, the active area of the outlet grilles should be between 770 and 880 cm².
The active area of the inlet grilles should be between 440 and 720 cm². Properly positioning the openings supports airflow around the body and the safe operation of the entire installation.
The selection of materials, grille layout, and installation method should be entrusted to a qualified installer. They should also consider the chimney parameters, required clearances, and air supply method.
P265GH boiler steel body
The insert casing is made of P265GH boiler steel grade compliant with EN 10028-2This material is intended for applications requiring operation at elevated temperatures.
The solid steel body ensures the stability of the entire structure. At the same time, the doors, made of a special profile, maintain the required rigidity during regular use.
Personalization of the ALBERO AL11S.HD appearance
The ALBERO series allows you to match selected insert elements to the character of your interior. Available personalization options include a handle, grilles, and a black concrete fireplace insert.

The dimensions of the fireplace insert are: 687 × 1064 × 506 mmThe design provides a wide view of the fire while also allowing for a proportionate design to fit a larger living room or open-plan living area.
The device weighs 132 kg. Therefore, the surface should have adequate load-bearing capacity and be prepared in accordance with the requirements for the installation of solid fuel heating devices.
Before installing the structure, it is also necessary to take into account the space needed to connect the flue pipe, supply external air and maintain the required distances from flammable elements.
Compliance with Ecodesign, BImSchV II and 15a B-VG
The ALBERO AL11S.HD fireplace insert meets the requirements Ekoprojekt, BImSchV II and 15a B-VGThe device has an energy efficiency class of A.
