Wall-mount garage heaters

Three wall-listed electric classes cover most garages: a infrared panel mounted at with side clearance, a wall/ceiling fan-forced unit on a , and a shop heater on a . Pick by output and clearance the manual actually publishes — not by which one looks biggest in a photo.

Spec-based picks, not a ranking

Nobody on this page has run these heaters side by side in the same garage over a winter, so nothing here is called "best." Each pick below is the smallest class whose manual figures actually cover a given job: a workbench panel, a 1–2 car garage, or a 2–3 car shop. Match your garage to the job, then check the clearance row against your actual wall.

120V WALL INFRARED · 1.5 KW

Heat Storm HS-1500-TT

plugged into an existing outlet. Mount at or higher, with to either side and above. Best for a workbench or a single bay, not a whole garage.

Manual: not where gasoline, paint or flammable liquids are used or stored.

Or the Dr. Infrared DR-238 (, mounts at or higher): Check price on Amazon ↗

Manual: the lowest part of the heater must be at least 94.5 in above the floor, wall or ceiling mounted, and a wall mount needs 15.8 in to the ceiling, so check your ceiling height first; a standard 8 ft ceiling will not meet it. Not where gasoline, paint or flammable liquids are used or stored. Plug it straight into the outlet: never an extension cord or power strip. Do not leave it unattended when in use.

Price class: $

240V WALL/CEILING · 5 KW

Fahrenheat FUH54

() on a , . The manual gives a floor clearance for a ceiling mount; it doesn't publish a separate side-wall clearance figure for a wall install, so follow the mounting bracket instructions in the box, not a guess.

Manual: not where gasoline, paint or flammable liquids are used or stored.

240V WALL/CEILING SHOP · 7.5 KW

Dr. Infrared DR-975

at on a , . The manual calls for clearance on each side and off the back wall — check that gap before you pick a stud.

Manual: “WARNING – RISK OF FIRE, DO NOT USE AS A RESIDENTIAL OR HOUSEHOLD HEATER.” Also not where gasoline, paint or flammable liquids are used or stored. Ask Dr. Infrared whether your garage counts as residential before you buy.

Clearances, side by side

Every figure below is the manual's own number for that model, not a rule of thumb applied across brands — two heaters at nearly the same wattage can still call for different clearances.

A dash means that model's manual doesn't publish that figure — don't carry a number over from a different unit.

What not to bolt to a wall

  • Why not a 120V portable utility heater (1,500W)? A plug-in portable heater is built as a floor or bench unit with its own tip-over shutoff — it isn't listed for a fixed wall mount. Use the wall-listed HS-1500-TT instead if you want the heater off the floor.
  • Why not a Portable propane radiant heater with ODS (Buddy/Big Buddy)? A propane radiant heater is a floor-standing, attended-use tool by its own manual, never a fixed wall or ceiling installation.

Safety at the point of installation

A wall-mounted 120V unit still needs GFCI protection on the outlet it plugs into (). A hardwired 240V unit is sized as a continuous load — breaker and wire at 125% of the nameplate draw, not the running amps alone (). Your electrician and your local code edition govern.

For a heavier ceiling-only install, see ceiling-mount garage heaters →. For a garage sized from your own dimensions instead of these three classes, run the garage heater calculator →.
