The electricSchwank 4000W Dual Element is a 39-inch electric patio heater for wall, ceiling, or flush-mounted installation with custom powder coating options.
The electricSchwank 4000W Dual Element is built for spaces that need stronger radiant heat while maintaining a clean, professional appearance. Its dual quartz element design makes it well suited for covered patios, terraces, restaurants, outdoor dining areas, and indoor/outdoor transition spaces.
The stainless steel construction helps resist corrosion in exposed environments. Optional custom powder coating is available in Almond, Beige, Biscuit, Black, Bronze, and White for projects where the heater needs to blend with surrounding architecture or décor.
This dual element model can be paired with a two-stage wall switch, allowing each heating element to be controlled independently. This gives users more flexibility when full heat output is not always needed.
The quartz elements emit infrared heat that warms people and surfaces directly. This helps maintain effective comfort in outdoor areas where wind and airflow can reduce the performance of traditional air-based heating systems.
The electricSchwank 4000W Dual Element supports multiple installation methods for residential and commercial projects.
Wall Mounted Installation
The included swivel brackets allow the heater to be mounted on a wall and angled toward the desired heating area. This keeps floor space clear and supports targeted heat placement.
Ceiling Mounted Installation
Ceiling installation positions the heater overhead for a cleaner layout. This works well above seating areas, dining areas, covered patios, and commercial terraces.
Flush Mounted Installation
An optional flush mount kit is available for recessed installation. This creates a more integrated ceiling appearance for design-focused spaces.
This model is available in 208V and 240V configurations. The recommended mounting height is 8 feet to 12 feet. Approximate heat coverage is 8 feet by 10 feet for this 4000W model.
Installation should follow the user’s manual, manufacturer requirements, and local electrical codes.
The electricSchwank 4000W Dual Element is designed for flexible heat control and long-term performance.
A two-stage wall switch is available to control each heating element independently. This allows partial or full output depending on comfort needs and site conditions.
Key functional features include dual quartz infrared elements, low-clearance installation compatibility, stainless steel construction, and UL Listed indoor/outdoor installation approval.
Also available in 3000and 6000 Watts. Low power single element heaters are ideal for residential and indoor installations, available in 500, 750, 1000, and 1500 Watts.
Note: Suggested mounting heights vary depending on the outdoor temperature and preferred coverage area. Please see this guide for more details.
