The W Series W-750 Marine Grade from Infratech
750 watts of 93%-efficient infrared heat from a 19-1/2" single-element quartz-tube heater in 316 marine grade stainless steel: 120V operation, from $836, UL & cUL listed, made in Gardena, California, and backed by a 3-year parts warranty.
Choose the Marine UpGrade if this heater will live near saltwater, on an exposed roof deck, or anywhere coastal, alpine, windy, or humid conditions punish standard stainless — 316 holds its finish where 304 shows tea staining first.
It is not a furnace substitute — Infratech states these radiant heaters are not a replacement for forced air or ductless heating. It must be hard-wired by a licensed electrician (there is no plug).
Specifications
Keep 18" of clearance at the sides and ends, 36" in front, and 6" behind the heater; wall mounts sit at least 12" below the ceiling angled 30–60° down, and the minimum mounting height is 6' (UL) or 8' (UL/cUL). Power is 120V, drawing 6.3 A at 120V, on a dedicated hard-wired circuit.

Answers to common questions
Do I need an electrician to install it?
Yes. Every W Series heater is permanently installed and hard wired by a licensed electrician to NEC and local codes — the housing is drilled and threaded for standard 1/2" conduit, and outdoor installs use components rated IPX4. There is no plug-in option.
Can it stay outside in the rain?
It's all-weather construction, and the manual requires outdoor wiring components with a minimum IPX4 rating — but Infratech recommends hanging it under a roof or weather cover when possible — it will last longer and look better protected from rain and snow. For the Marine UpGrade, rinse salt deposits with fresh water and a soft cloth after storms or heavy spray — 316 is stainless, not stain-free.
What controls does it need?
A control or switch is required and every Infratech control is sold separately — from simple on/off and duplex switches to INF regulators, the smart dimmer/switch, and zoned control panels. One caution from the manual: using competitor controls or accessories may void the Infratech warranty.
