Dr. Infrared DR-988 240V Industrial Garage Heater
The picks scale up here from a plug-in convenience heater to a serious garage furnace. Bob Vila's tested best infrared 240V heater, the DR-988 draws 4,800W at 208V or 5,600W at 240V through a NEMA 6-30P plug into a dedicated 30-amp outlet, and its forced-air blower with a 37–113°F adjustable thermostat is rated to warm workshops, warehouses, and detached uninsulated garages far beyond what any 120V heater can reach. It sits on the floor or mounts to a wall or ceiling, and its industrial finish and duty rating are meant for the space you actually work in. The trade-off is straightforward: it requires an electrician and a dedicated 240V circuit before you can plug it in.

Our Verdict
The pick when a 120V heater is not enough. Bob Vila's tested best-infrared 240V pick, the DR-988 draws 5,600W at 240V through a NEMA 6-30P plug and its industrial forced-air blower with a 37–113°F thermostat covers workshops and detached uninsulated garages a plug-in cannot. It ranks below the Phoenix because it needs a dedicated 30-amp 240V outlet before you can use it — an electrician job for most homes — and its Amazon buy box typically routes through third-party sellers rather than Amazon direct.

Alternatives to Consider
Heat Storm HS-1500-PHX Phoenix Infrared Heater
Heat Storm
The safest first pick for a typical home garage, and Bob Vila's tested best-overall garage heater. The Phoenix is an infrared quartz heater that plugs into any 120-volt outlet — no electrician, no dedicated circuit, no gas plumbing — with two output steps (750W and 1500W), a digital thermostat, a remote, and a wall bracket that keeps it off the floor and out of the way. Infrared warms objects and people in its beam directly instead of trying to heat the whole air volume, so it feels warm quickly in an insulated one- or two-car garage and its housing stays cool enough to touch. It is not the pick for a large uninsulated shop — a 1500W plug-in cannot outrun that — but for the vast majority of home garages it is the least-fuss way to a reliably warm workspace.
Mr. Heater Big Buddy MH18B Portable Propane Heater
Mr. Heater
The escape hatch for garages without a suitable outlet at all. The Big Buddy is a portable radiant/convection propane heater that runs on two 1 lb bottles (or, with the included hose adapter, an external 20 lb tank), producing 4,000 / 9,000 / 18,000 BTUs across three settings — enough to warm roughly 450 square feet without any electrical hookup. Independent expert roundups (Bob Vila, findingdulcinea, Garage Gym Reviews) consistently rank the Big Buddy line as the best propane option for garages, and the MH18B specifically adds an auto low-oxygen shut-off, a tip-over safety switch, and a piezo igniter — no matches, no batteries needed for ignition. Because it burns propane, you must crack a door or window for ventilation.
Dr. Infrared DR-968 Portable Space Heater
Dr. Infrared
The best value in the lineup and the most-recommended portable 120V heater across the reputable roundups. The DR-968 is a dual infrared quartz + PTC heater in a compact wheeled cabinet that plugs into a standard outlet and pushes 1500W / roughly 5,200 BTU with a low-noise blower and an electronic thermostat that will hold a target between 50°F and 85°F. It has a 12-hour auto-shutoff timer, tip-over and overheat protection, and a full remote. It does not have the wall-mount elegance of the Heat Storm Phoenix or the raw output of the DR-988, but for a workbench-side heater in a small-to-medium garage it is the pick that gets the most for the least.
Comfort Zone CZ285 Electric Ceramic Utility Heater
Comfort Zone
The best-budget pick and the most-owned heater on this list by a wide margin — nearly 29,000 Amazon ratings averaging 4.2 stars. The CZ285 is a straightforward 1500W ceramic garage/workshop utility heater with a metal frame, a pivoting cradle base, a mechanical adjustable thermostat, an integrated overheat sensor, and a carry handle. There is no thermostat display, no remote, no smart features — just a heater you can slap onto a bench or the floor, plug into a 120V outlet, and use. Comfort Zone is the brand Pro Tool Reviews awards multiple times in its electric garage heater roundup, and this specific model is repeatedly cited as the best-under-$100 pick.
