Infrared Patio Heater · 4000W 240V · Single Element Black Slimline · Infratech SL-4024-BK
What this product is for
This electric infrared radiant heater is used to deliver directional comfort heat to covered outdoor patios, terraces, restaurant seating areas, and indoor commercial spaces. The SL-4024-BK is a 4000W, 240V single-element unit in a black slimline housing for applications where a long, narrow heater profile suits the mounting area.
Use for
Use for wall or ceiling-mounted comfort heating in covered exterior spaces, screened areas, hospitality seating, vestibules, workshops, and similar locations where targeted radiant heat is preferred over forced air. It is commonly used where electricians and contractors need a 240V heater drawing approximately 16.7A.
Avoid for
Avoid using this heater as a whole-home or whole-room primary heating source, or in fully exposed locations where wind will quickly reduce perceived warmth. Do not size or specify it as exact area coverage without confirming mounting height, exposure, and project conditions.
Best for
Best for covered patios and commercial seating areas that need clean electric radiant heat without moving air. It also suits projects where the black finish is preferred for darker ceilings, pergolas, or architectural surfaces.
Installed in
Typically installed on walls, ceilings, covered decks, pergolas, restaurant patios, and indoor commercial areas, subject to manufacturer clearances and local code. The slimline body is approximately 63.5 in (1613 mm) long, which helps when planning spacing and mounting layout.
Why this product exists
This model exists for projects that need higher-output radiant heat from a single-element 240V heater in a streamlined form factor. Compared with bulkier units, the slimline format helps when wall space, ceiling lines, or visual impact matter.
Compared with similar products
Compared with lower-wattage electric patio heaters, this 4000W model is typically chosen for larger seating zones or installations with higher mounting positions, subject to layout and exposure. As a rule of thumb, electric comfort heat performance outdoors depends heavily on wind and mounting geometry, so heater count and placement usually matter as much as wattage. Continuous-load circuit sizing should also be checked carefully, since 4000W at 240V is approximately 16.7A and may require branch-circuit planning beyond a nominal 20A load allowance. Actual performance depends on installation conditions, insulation, layout, and local electrical code.
