Dual-Element Infrared Patio Heater · 4000W 240V · 39 in (991 mm) Biscuit Finish · Infratech WD-4024-SS-BI
What this product is for
The Infratech WD-4024-SS-BI is a dual-element electric infrared radiant heater for outdoor patios, covered decks, hospitality spaces, and other areas where direct radiant heat is preferred over forced air. It is a 4000W, 240V WD-Series model in a biscuit body finish with a 39 in (991 mm) housing.
Use for
Use for covered patios, restaurant seating areas, pergolas, balconies, and similar residential or light commercial spaces where a concentrated heat pattern is needed. This model is commonly installed at approximately 8 to 10 ft (2.4 to 3.0 m) mounting heights and can be paired with compatible Infratech control options, including duplex/stack switch or custom controls.
Avoid for
Avoid using this heater as a whole-room indoor space heater or where exposure, clearance, or mounting conditions do not match manufacturer requirements. It is also not the right choice when a wider, softer heat pattern from a longer single-element heater is preferred.
Best for
Best for electricians, contractors, and designers specifying a compact dual-element heater for premium patio heating, recessed-style applications, or projects needing a shorter 39 in body with concentrated output. The biscuit finish can suit architectural installations where a softer body colour is preferred over stainless appearance.
Installed in
Typically installed on wall, ceiling, pole-mount, or flush-mount compatible applications, subject to the correct mounting accessories and clearances. WD-Series heaters are commonly selected for covered outdoor living areas, restaurants, hotels, and similar gathering spaces.
Why this product exists
This heater exists for projects that need stronger, more concentrated radiant heat from a shorter fixture length than many single-element models. Dual-element WD-Series heaters are intended for larger-scale coverage needs while keeping a low-profile architectural form factor.
Compared with similar products
Compared with Infratech single-element W-Series heaters, the WD-Series uses dual elements to deliver more concentrated heat and is often chosen for recessed or premium outdoor heating layouts. As a practical rule of thumb, a 4000W electric heater is commonly used where stronger spot or zone heating is needed, but actual comfort coverage depends on mounting height, wind exposure, ambient temperature, and layout.
For branch circuit planning, this heater draws 16.7A at 240V, so electricians typically place it on a properly sized 240V circuit with controls matched to the connected load and local code requirements. Continuous-load sizing, conductor selection, and overcurrent protection must be confirmed by the installer.
