FAQ
DO I NEED TO PURCHASE CONTROLS SEPARATELY?
Yes. All Infratech SL Series heaters require a compatible control to operate. Controls are selected based on your heater configuration, electrical setup, and desired functionality. 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?
Voltage must match your existing electrical supply. Most residential installations use 240V. SL Series models are available in 120V, 208V, 277V and 240V configurations depending on model. Always confirm voltage requirements with a licensed electrician prior to ordering.
CAN THIS HEATER BE USED INDOORS?
Yes. Infratech SL 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 SL SERIES HEAT?
Heat coverage depends on the specific model, wattage, and mounting height. SL 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 but generally ranges from 6 to 10 feet. Each product page lists the optimal mounting height for that specific heater.
CAN THE HEATER BE MOUNTED ON A WALL OR CEILING?
Yes. SL Series heaters can be wall mounted or ceiling mounted. Mounting brackets are included. If a flush mount installation is required, Infratech W or WD Series heaters are the appropriate solution.
IS THE HEATER WEATHER RESISTANT?
Yes. Infratech SL 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?
SL Series heaters are available in stainless steel and black.
ARE ALL FINISHES RETURNABLE?
Powder-coated finishes are non-returnable (black). Stainless steel finishes may be subject to standard return guidelines. Please review our Return & Refund Policy prior to ordering.
