Radiant Patio Heater · 1600W 240V · Slimline Single Element · Infratech SL-1624
What this product is for
The Infratech SL-1624 is a slimline electric radiant patio heater designed to add directional comfort heat to outdoor and semi-sheltered spaces. It uses a single quartz element in a narrow anodized aluminium housing for applications where wall or ceiling space is limited.
Use for
Use for patios, balconies, covered decks, outdoor dining areas, pergolas, and similar spaces where 240V radiant heat is preferred over gas-fired heating. It is commonly selected for surface-mount installations where a compact 29.5 in (749 mm) heater fits the layout better than longer dual-element models.
Avoid for
Avoid using this heater as whole-room indoor space heating or where broad-area heat coverage is required. It is also not the right choice where mounting height, exposure to wind, or open-sided conditions will reduce effective comfort heat beyond what a 1600W single-element unit can typically provide.
Best for
Best for smaller seating zones and targeted spot heating in outdoor residential or light commercial settings. As a rule of thumb, this size is typically used where a compact heater is needed for a focused comfort zone rather than a large open patio. Actual performance depends on installation conditions, mounting height, ambient temperature, and local electrical code.
Installed in
Typically installed on exterior walls, ceilings, or other surface-mount structures in covered outdoor areas. Manufacturer literature indicates installation heights up to 11 ft (3.4 m), and distributor references commonly show an effective comfort area of approximately 5 x 5 ft (about 25 sq ft / 2.3 m²) when properly positioned.
Why this product exists
This model exists for projects that need compact electric infrared heat with a cleaner visual profile than larger patio heaters. The slim housing helps it blend into architectural finishes while still delivering 1600W of radiant output on a 240V circuit.
Compared with similar products
Compared with longer or higher-wattage Infratech heaters, the SL-1624 is intended for smaller heat zones and tighter mounting spaces. Compared with gas patio heaters, electric radiant heaters avoid fuel storage and open flame at the point of use, but they require the correct 240V electrical provision and should be sized to the seating area.
