Slimline Single Element Infrared Heater · 2400W, 208V, 42-1/2 in (1080 mm) · Stainless Steel Outdoor Unit · Infratech SL-2428
What this product is for
The Infratech SL-2428 is a slimline single-element infrared heater for spot and zone heating in outdoor living areas, covered patios, restaurant seating, and similar commercial or residential spaces. It is a 208V model rated 2400W and 11.5A with a 42-1/2 in (1080 mm) body.
Use for
Use for surface-mounted radiant heat where a narrow-profile heater is needed and the available supply is 208V. Suitable for patios, pergolas, covered decks, hospitality seating areas, and other installations where direct infrared heat is preferred over forced air.
- 208V heating circuits
- Outdoor or indoor covered applications where the installation manual is followed
- Mounting heights typically up to 10 ft (3.0 m), depending on layout and comfort target
Avoid for
Avoid using this heater where only 240V supply is available unless the exact heater voltage matches the project design. Do not use where clearance, mounting orientation, or weather exposure falls outside the manufacturer instructions. Not intended as whole-room space heating for enclosed interiors.
Best for
Best for electricians and contractors specifying a clean-looking infrared heater for narrower wall or ceiling runs. The slimline housing and single-element format suit smaller seating zones and projects where appearance matters as much as heat placement.
Installed in
Typically installed in covered residential patios, condo amenity spaces, restaurants, clubs, and light commercial outdoor gathering areas. A practical rule of thumb is to match heater selection to mounting height, wind conditions, and occupied zone size rather than floor area alone. Actual comfort performance depends on installation conditions, insulation, layout, and local electrical code.
Why this product exists
This model provides directional radiant heat without moving air, making it useful where occupants need warmth in open or semi-open spaces. Compared with bulkier heaters, the SL-Series is designed with a narrow profile, stainless steel trim, and flexible mounting via the series T-slot system.
Compared with similar products
Compared with larger dual-element patio heaters, the SL-2428 is a lower-wattage single-element option for smaller zones or tighter mounting spaces. Compared with 240V versions, this 208V model is intended for buildings and commercial services using 208V power, so voltage matching is important at the design stage.
