HWAM 3640 stove — Scandinavian Heating Design
The HWAM 3640 stove is a premium Danish wood burning stove designed for efficient home heating and modern interiors. Its large curved front glass provides an excellent view of the flames while creating a warm and comfortable atmosphere in any living space.
The range is available in classic (C) and modern (M) versions with black and grey steel finishes. In addition, optional natural stone cladding versions include Soapstone, Tobacco, Dark Galaxy, and Moca Cream finishes. Therefore, the stove fits naturally into both modern and traditional interiors.
HWAM 3640 Design & Comfort
The stove features a tall Scandinavian structure with smooth curves and elegant proportions. Moreover, its slim body allows easier placement in different room layouts without taking excessive floor space.
The curved glass door improves flame visibility while enhancing the overall room atmosphere. Consequently, the fire remains a natural focal point within the living area.
3640 Stove Heating Performance
The HWAM 3640 uses convection heating to distribute warmth evenly across the room. As a result, indoor temperature remains stable during daily operation.
The Air wash system helps keep the glass cleaner during use. Therefore, users continue to enjoy a clear and uninterrupted flame view with reduced maintenance.
HWAM 3640 Combustion Technology
The stove uses the HWAM® Autopilot™ system to regulate airflow automatically during combustion. Consequently, heat output remains balanced while fuel consumption stays efficient.
The automatic control system responds continuously to temperature changes inside the stove. Furthermore, this helps improve combustion efficiency while reducing emissions during operation.
3640 Installation & Flexibility
The unit supports both top and rear flue outlet options for flexible installation. In addition, the optional fresh air kit improves compatibility with modern airtight homes.
Natural stone cladding versions also provide additional heat retention after the fire has reduced. Therefore, room comfort continues for longer periods after active burning.
The HWAM 3640 stove combines Danish craftsmanship, excellent flame visibility, and efficient combustion technology, making it a reliable long-term heating solution.
