1. Fahrenheat FUH54 🏆 BEST OVERALL

Price: $199 | Best for: A heated two-car garage on a 240V circuit

The Fahrenheat FUH54 is the default answer for most garages. It is a 240V (also 208V-capable) 5,000-watt forced-convection unit that delivers about 17,065 BTU/h and comfortably heats up to roughly 600 square feet of enclosed space. It mounts to a wall or ceiling on an included bracket, swivels for airflow, and uses a built-in single-pole thermostat plus an overheat cutout.

It is hardwired into a dedicated 30-amp circuit, so plan on an electrician if your panel isn't ready. The compact steel housing and proven internals are why it shows up on nearly every tested list.

Pros:

• Strong 17,000 BTU output for the price
• Adjustable mounting bracket and louvers
• Built-in thermostat and overheat protection
• Compact, durable steel cabinet

Cons:

• Requires a dedicated 240V/30A circuit and hardwiring
• Fan is audible at full output

Verdict: The best blend of power, safety, and price — the one to buy if you can run 240V.

2. Dr. Infrared Heater DR-975

Price: $369 | Best for: Big, drafty workshops up to 1,000 sq ft

The Dr. Infrared Heater DR-975 is the heavy hitter. It is a 240V, 7,500-watt hardwired forced-air unit rated at roughly 25,597 BTU/h, enough for shops in the 470–750 sq ft range and larger insulated spaces approaching 1,000 sq ft.

It includes a remote-controlled thermostat (50–85°F), wall or ceiling mounting, and a tilt head to aim heat where you work. The extra wattage means a bigger circuit and higher running cost, but no electric garage unit on this list throws more heat.

Pros:

• Class-leading 25,597 BTU output
• Remote-controlled digital thermostat
• Wall/ceiling mount with adjustable tilt

Cons:

• Needs a 240V/40A circuit; higher operating cost
• Overkill for a small single bay

Verdict: The pick when raw heat for a large shop matters more than efficiency.

3. Comfort Zone CZ220 💎 BEST VALUE

Price: $159 | Best for: Buyers who want FUH54-class heat for less

The Comfort Zone CZ220 delivers nearly the same numbers as our top pick for less money. It is a 240V, 5,000-watt ceiling-mount fan-forced industrial heater rated at 17,065 BTU/h, with adjustable louvers, a thermostat, a remote, and safety overheat protection. Build quality is a small step below the Fahrenheat, but the heat output, coverage, and feature set are equivalent, which is what earns it the value crown.

It hardwires into a 240V/30A circuit like the others in its class.

Pros:

• Same 17,065 BTU as pricier rivals
• Includes a remote control
• Adjustable louvers and overheat protection

Cons:

• Housing and fan feel less rugged than the Fahrenheat
• Mounting hardware is basic

Verdict: Nearly identical heat to the FUH54 at a lower price — the smart-money choice.

4. NewAir G73

Price: $229 | Best for: A clean-looking hardwired install up to 500 sq ft

The NewAir G73 is a 240V, 5,000-watt hardwired heater that heats up to about 500 square feet. It stands out for design: an ivory cabinet, adjustable louvers, and a tilt head that lets you ceiling-mount it and aim warm air down toward a workbench. A thermostat and overheat shutoff are built in.

It runs on a 240V/30A circuit and is a good fit for finished garages where appearance matters as much as output.

Pros:

• Clean, finished-garage aesthetic
• Tilting head and adjustable louvers
• Solid 5,000W output for 500 sq ft

Cons:

• Slightly less coverage than the FUH54
• Hardwired only, no plug-in option

Verdict: The best-looking 240V unit for a finished or attached garage.

5. Mr. Heater Big Maxx MHU50

Price: $549 | Best for: Gas-heated garages where electricity is costly

The Mr. Heater Big Maxx MHU50 is the gas answer. It is a ceiling-suspended natural gas unit heater rated at 50,000 BTU/h (with an available propane conversion kit), sized for a two- to three-car garage.

Because gas is cheaper than resistance electric heat in most regions, running costs are low, but you must vent it and run a gas line, which raises install complexity. It uses a spark-ignition system, a low-profile cabinet, and works with an external thermostat.

Pros:

• Low operating cost versus electric
• 50,000 BTU heats a big garage fast
• Natural gas or propane (with kit)

Cons:

• Requires venting and a gas line — professional install
• Higher upfront cost

Verdict: The right call for large garages where gas beats electric on running cost.

6. Dr. Infrared Heater DR-988

Price: $329 | Best for: A portable 240V heater you can roll between bays

The Dr. Infrared Heater DR-988 is a portable industrial unit that plugs into a 240V outlet rather than hardwiring. It runs 5,600 watts on 240V (or 4,200W on 208V) for roughly 18,500 BTU/h at full power.

It ships with a 6-foot cord and a NEMA 6-30P plug that needs a matching 6-30R 250V/30A outlet, plus a built-in thermostat (37–113°F). The cart-style frame and wall/ceiling mounting options make it flexible if you don't want a permanent install.

Pros:

• Plug-in 240V — no hardwiring
• ~18,500 BTU and wide thermostat range
• Portable or mountable

Cons:

• Needs a dedicated 240V 30-amp receptacle
• Bulkier than fixed wall units

Verdict: The best choice if you want 240V heat without committing to hardwiring.

7. King Electric KBP2406

Price: $279 | Best for: A rugged wall/ceiling mount in a working shop

The King Electric KBP2406 is a 240V, 5,700-watt garage and shop heater built for abuse. It mounts to a wall or ceiling, swivels on its bracket, and runs about 19,400 BTU/h with a built-in thermostat and overheat protection. King's heaters are known for heavy-gauge construction and serviceable internals, which is why pros keep buying them.

It hardwires into a 240V circuit and aims heat with adjustable louvers.

Pros:

• Rugged, heavy-gauge build
• 5,700W / ~19,400 BTU output
• Swivel bracket and adjustable louvers

Cons:

• Plain industrial looks
• Hardwired install required

Verdict: The durability pick for a hard-working shop that runs heat daily.

8. Modine Hot Dawg HD45

Price: $899 | Best for: A permanent, high-efficiency gas install

The Modine Hot Dawg HD45 is the premium gas option. It is a horizontal natural gas (or propane) suspended unit heater rated at 45,000 BTU/h input, delivering roughly 36,900 BTU/h output at about 82% thermal efficiency — enough for a two- to two-and-a-half-car garage.

Modine is the name commercial installers trust, with a powered exhaust, low-profile aluminized-steel cabinet, and long service life. It requires venting and a gas line, so this is a planned, permanent install.

Pros:

• 82% efficiency with low running cost
• Commercial-grade reliability
• Natural gas or propane

Cons:

• Highest upfront price on the list
• Venting and gas line needed

Verdict: The long-haul gas heater for owners who want it installed once and forgotten.

9. Mr. Heater Big Buddy MH18B

Price: $129 | Best for: Portable, no-wiring heat in a detached garage

The Mr. Heater Big Buddy MH18B is the grab-and-go propane radiant heater. It runs 18,000 BTU/h and heats up to about 450 square feet, working off 1-lb cylinders or a 20-lb tank with a hose.

There is no wiring at all — ideal for a detached garage or shed with no spare circuit. It has a tip-over shutoff and a low-oxygen sensor, but because it is a vent-free combustion heater, you must crack a door or window for fresh air and never run it overnight.

Pros:

• Zero electrical install — fully portable
• 18,000 BTU radiant heat
• Tip-over and low-oxygen safety shutoffs

Cons:

• Vent-free — requires fresh-air ventilation
• Not for unattended or overnight use

Verdict: The best portable propane option when you can't or won't run wiring.

10. Heat Storm HS-1500-PHX

Price: $119 | Best for: A small, insulated single bay on a standard outlet

The Heat Storm HS-1500-PHX is the 120V plug-in choice. It is a 1,500-watt infrared heater (about 5,100 BTU/h) that plugs into any standard household outlet — no electrician, no new circuit. Infrared warms objects and people directly, so it feels effective in a drafty space, and the unit includes an energy-saving mode, a remote, and quiet operation.

It is only enough for a small, insulated single-car bay or a work zone, not a whole cold garage, but it is the cheapest, simplest way in.

Pros:

• Plugs into a standard 120V outlet
• Infrared warms you directly
• Remote and quiet operation

Cons:

• Only 1,500W — limited to small spaces
• Won't heat a full two-car garage

Verdict: The easiest, cheapest entry point for a small or spot-heated bay.

Buyer Decision Tree — Which One's Right for You?

What to Look For When Buying a Garage Heater

• Electrical capacity first. A 120V outlet caps you at 1,500W (about 5,100 BTU). Real garage heat usually needs a 240V circuit (5,000W+) or gas. Check your panel before you shop.
• BTU/wattage for your square footage. Budget roughly 10 watts per square foot for an insulated garage, more if it's drafty. A 600 sq ft two-car bay wants about 5,000W / 17,000 BTU.
• Forced-air vs. Infrared. Forced-air heats the whole room evenly and quickly; infrared warms people and surfaces directly, which feels better in drafty or rarely-heated spaces.
• Thermostat and controls. A built-in thermostat and a remote let the heater cycle instead of running flat-out — that saves money and reduces wear.
• Mounting vs. Portability. Hardwired wall/ceiling units free up floor space; portable plug-in or propane units move between bays but need somewhere to sit.
• Safety shutoffs. Look for overheat cutoffs on electric units and tip-over plus low-oxygen sensors on propane units.
• Ventilation for gas. Any vent-free propane heater needs fresh air; suspended gas unit heaters like the Big Maxx and Hot Dawg must be vented to the outside.

What matters less than marketing implies: WiFi apps, oscillation gimmicks, and inflated BTU claims on undersized 120V units. A correctly sized heater on the right circuit beats a feature-loaded one that can't draw enough power.

FAQ

What size garage heater do I need for a two-car garage? Plan on about 5,000 watts / 17,000 BTU of electric heat for a typical insulated two-car (≈600 sq ft) garage, or roughly 45,000–50,000 BTU of gas. The Fahrenheat FUH54 and Comfort Zone CZ220 are sized exactly for this.

Can I run a garage heater on a regular 120V outlet? Only a small one. A standard 120V outlet limits you to 1,500 watts (≈5,100 BTU), like the Heat Storm HS-1500 — fine for a small insulated bay or spot heating, but not a whole two-car garage. Bigger heaters need a 240V circuit.

Is electric or gas cheaper to run in a garage? Gas is usually cheaper to operate where natural gas is available, which is why the Mr. Heater Big Maxx and Modine Hot Dawg win on running cost. Electric units cost less upfront and install more simply, but resistance heat costs more per BTU in most regions.

Are propane garage heaters safe indoors? Vent-free units like the Mr. Heater Big Buddy have tip-over and low-oxygen shutoffs and are rated for indoor use, but you must provide fresh-air ventilation and never run them while sleeping. Suspended gas heaters like the Hot Dawg are vented to the outside and are safer for continuous use.

Do I need an electrician to install a garage heater? For any 240V hardwired unit (FUH54, DR-975, CZ220, NewAir G73, King KBP2406), yes — you need a dedicated circuit and proper connection. Plug-in 240V units like the DR-988 need a matching 30-amp receptacle. The 120V Heat Storm and propane Big Buddy need no electrician.

How many BTU is 5,000 watts? About 17,065 BTU/h. Watts convert to BTU at roughly 3.41 BTU per watt, so a 7,500W unit like the DR-975 produces around 25,597 BTU.

Bottom Line

For most garages, the Fahrenheat FUH54 ($199) is the Best Overall — 17,000 BTU of 240V forced-air heat with a thermostat and overheat protection at a fair price. If you want nearly the same performance for less, the Comfort Zone CZ220 ($159) is the Best Value, matching the output and adding a remote.

Shopping by what you've got in the garage — a 120V outlet, a 240V circuit, or a gas line — is the fastest way to the right unit, so use the decision tree above to route yourself to the correct pick.
