Description
The Infratech WD40 WD Series Dual Element Heater delivers powerful 4000 watt infrared performance in a streamlined architectural profile. Designed for covered patios, outdoor living spaces, restaurants, and commercial applications, the WD40 uses dual quartz heating elements and medium wave infrared technology to provide strong, consistent comfort without noise, odor, or visible flame.
Engineered and manufactured in the USA, the WD40 features durable stainless steel construction, versatile mounting options, and compatibility with Infratech control systems. It is an excellent solution when you want higher perceived heat output and more balanced coverage for larger seating areas.
For coastal, high humidity, or salt air environments, this model is available in a Marine Grade 316 stainless steel construction. Standard models use corrosion-resistant 304 stainless steel. The 316 upgrade provides enhanced protection against saltwater exposure and harsh environmental conditions.

FAQ
DO I NEED TO PURCHASE CONTROLS SEPARATELY?
Yes. All Infratech W and WD Series heaters require a compatible control to operate. Controls are selected based on your heater configuration, electrical setup, and desired functionality. Options range from simple on/off switches to advanced smart home integrations. If you are unsure which control is right for your space, our TTH Concierge team can assist.
WHICH CONTROL OPTION IS BEST FOR MOST HOMEOWNERS?
Most residential installations use a basic on/off switch or an input regulator. Larger patios or multi-heater layouts often benefit from custom control panels. Smart controls are recommended for homes with existing smart home systems or when app-based control is desired.
WHAT VOLTAGE SHOULD I CHOOSE?
Most residential installations use 240V. Commercial projects may use 208V, 277V, or 480V. Always confirm voltage requirements with a licensed electrician prior to ordering.
WHAT IS THE DIFFERENCE BETWEEN W AND WD SERIES?
W Series heaters use a single heating element. WD Series heaters use dual heating elements, providing more balanced heat distribution and increased perceived warmth in the same footprint. WD models are often selected when stronger performance is desired at lower mounting heights.
CAN THIS HEATER BE USED INDOORS?
Yes. Infratech W and WD Series heaters are UL listed for both indoor and outdoor use when installed according to manufacturer guidelines and local building codes.
HOW MUCH AREA DOES THE W/WD SERIES HEAT?
Heat coverage depends on the specific model, wattage, and mounting height. W and WD Series heaters are designed to provide focused, directional warmth rather than ambient heating. Multiple heaters may be required for larger spaces or open layouts.
WHAT IS THE RECOMMENDED MOUNTING HEIGHT?
Recommended mounting height varies by model. Each product page lists the optimal mounting height for that specific heater.
CAN THE HEATER BE MOUNTED ON A WALL OR CEILING?
Yes. W and WD Series heaters can be wall mounted, ceiling mounted, or recessed using a compatible flush mount frame that matches the heater length. Mounting brackets are included.
IS THE HEATER WEATHER RESISTANT?
Yes. Infratech W and WD Series heaters are rated IPX4 and are suitable for covered outdoor installations. They are designed to withstand typical outdoor conditions when installed properly.
WHAT FINISH OPTIONS ARE AVAILABLE?
W and WD Series heaters are available in stainless steel and a range of standard powder-coated finishes including white, biscuit, almond, beige, bronze, black, grey, and copper.
ARE ALL FINISHES RETURNABLE?
Powder-coated finishes are non-returnable. Stainless steel finishes may be subject to standard return guidelines. Please review our Return & Refund Policy prior to ordering.
WHAT IS THE DIFFERENCE BETWEEN STAINLESS STEEL AND MARINE GRADE?
Standard models are constructed from corrosion-resistant 304 stainless steel. Marine grade upgrades use 316 stainless steel, which provides enhanced protection in coastal, humid, or harsh environments.
IS PROFESSIONAL INSTALLATION REQUIRED?
Installation should be performed by a qualified electrician. Proper electrical planning and mounting height are critical for safety and performance.
WHERE ARE INFRATECH HEATERS MADE?
All Infratech heaters are proudly made in the USA.
WHAT WARRANTY IS INCLUDED?
Infratech W and WD Series heaters include a 3-year manufacturer warranty.
Delivery
Estimated delivery time is 2 weeks. Curbside freight delivery only. Customer is responsible for unloading and placement. See full Shipping Policy for details.
Returns Policy
Infratech custom powder-coated units are not eligible for return. Stainless, Marine Grade Stainless, and 8 standard colors (Almond, Beige, Biscuit, Black, Bronze, Copper, Grey, and White) are returnable within 30 days, but subject to applicable fees. See full Return Policy for details.
