The W Series W-3000 Marine Grade from Infratech
3,000 watts of 93%-efficient infrared heat from a 61-1/4" single-element quartz-tube heater in 316 marine grade stainless steel: an average 8' x 8' of coverage from a 7' – 9' mounting height, 240V, 277V, 208V, 480V variants, from $1,075, 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), and the 277V and 480V variants are rated "Commercial Use Only" — do not order those voltages for a home.
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 240V, 277V, 208V, 480V depending on the variant, drawing 12.5 A at 240V / 11 A at 277V / 14 A at 208V / 6 A at 480V, on a dedicated hard-wired circuit.
W-3000 Marine Grade vs. its closest Infratech options

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.
Which voltage should I order?
Match the circuit your electrician will run: this model comes in 240V, 277V, 208V, 480V versions, and the element must match the supply — a 240V element on 208V supply will warm but not glow or heat properly. The 277V and 480V variants are rated "Commercial Use Only" per the manual — don't order them for a residence.
How much area does it actually heat?
Infratech rates the W-3024 at 8' x 8' average coverage from a 7' – 9' mounting height — up to 10' x 10' in protected areas, and closer to 6' x 6' in extreme cold or wind. Heating from two sides beats one big heater when you can do it.
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.
