Portable Gas Garage Heater: 7 Best Budget Picks (2026)

There’s a specific kind of cold that lives in a garage — the sort that settles into concrete and never quite leaves, even in a mild British winter. If you’ve ever tried to fix a bike puncture or sand down a shelf out there in January with your fingers going numb, you’ll already understand why a portable gas garage heater is one of the most quietly popular purchases among UK DIYers and hobbyists. Unlike a permanently plumbed-in system, it needs no installation, no electrician, and no waiting around — light it, and within a few minutes the space around you actually feels workable again.

What is a portable gas garage heater? In simple terms, it’s a freestanding heating appliance, fuelled by bottled butane or propane rather than mains gas or electricity, designed to be moved between spaces and used without any fixed wiring or pipework. That portability is exactly the appeal — and exactly why the market is so crowded with options ranging from bargain-basement cabinet heaters to trade-grade propane units built to survive a building site.

This guide breaks down what genuinely separates a good portable gas garage heater from a disappointing one, compares seven real products you can buy today, and works through gas garage heaters under £150, the butane garage heater versus propane debate, cylinder-fed heaters, mobility considerations, and how to think sensibly about occasional-use heating rather than running one as a full-time solution. We’ll also be upfront about the genuine safety considerations that any honest guide to gas heating has to cover.

Quick Comparison Table

Here’s the shape of the current market before the detailed breakdowns. All prices are indicative ranges checked at the time of research — always confirm current pricing on the product page before buying.

Every single option here clears the gas garage heaters under £150 bracket comfortably, which tells you something important about this category: you don’t need to spend big to get a genuinely usable garage heater, but the spread between roughly £50 and £110 still reflects real differences in fuel type, build quality, and safety features rather than arbitrary pricing. The propane-fuelled trade brands — Sealey Space Warmer LP14 and Draper 07867 Free-Standing Propane Heater — sit toward the middle on price but generally outperform similarly priced butane cabinet heaters on raw heat output, while the smaller cylinder-fed units like the Mr. Heater Portable Buddy trade outright power for genuinely superior portability and built-in safety sensors.

Top 7 Portable Gas Garage Heaters: Expert Analysis

1. ELPINE Portable Calor Gas Heater — best rock-bottom budget option

For anyone who just wants a working heater in the garage without spending big, the ELPINE Portable Calor Gas Heater is the cheapest genuinely usable option on this list. It’s a classic cabinet-style butane heater — the format most British households will recognise instantly, complete with a regulator and hose included in the box.

At 4.2kW across its heat settings, it produces a meaningful amount of warmth for a garage-sized space, and the cabinet design means the flame and burner are enclosed rather than exposed, which matters if you’ve got tools, dust sheets, or clutter nearby. Based on the spec sheet, this runs on standard butane cylinders widely available from hardware shops and petrol stations, so fuel access is rarely an issue.

This is the heater for someone popping into the garage for twenty minutes to grab something or do a quick repair, rather than settling in for a long session — cabinet-style butane heaters like this one are reasonably capable but not class-leading on efficiency. Aggregated review sentiment across similar ELPINE and near-identical cabinet-format heaters tends to be positive on straightforward heat output for the price, with a recurring theme of buyers noting the gas cylinder itself needs to be sourced separately and isn’t included.

Pros:

• ✅ Genuinely low entry price for a full-size cabinet heater
• ✅ Enclosed burner design suits a cluttered garage environment
• ✅ Uses widely available standard butane cylinders

Cons:

• ❌ Gas cylinder sold separately, adding to the real cost
• ❌ Less efficient than trade-grade propane alternatives

At around £50-£70 for the heater unit, this is the cheapest realistic entry into gas garage heating on this whole list — just budget for the cylinder on top.

2. Sealey Space Warmer LP14 — best trade-grade value

Sealey Space Warmer LP14 brings genuine trade-tool pedigree to this list — Sealey is a well-known name among mechanics and tradespeople, and this propane-fuelled unit with its own stand is built with that harder-wearing audience in mind rather than casual home use alone.

Rated at 15,354 BTU per hour (roughly 4.5kW), it edges out most of the butane cabinet heaters here on raw output while running on propane, which generally delivers more consistent heat in colder conditions than butane — a genuinely useful distinction for anyone using a garage through a proper UK winter rather than just autumn evenings. The integrated stand keeps the unit off the concrete floor, improving airflow to the burner and reducing the risk of it toppling over on an uneven surface.

What most buyers overlook about this model is that it’s designed primarily for well-ventilated workshop and outdoor-adjacent use rather than a small, sealed room — that’s standard for radiant propane space heaters generally, not a flaw specific to Sealey. Reviewers consistently praise the solid trade-brand build quality and stable stand design, with a smaller number noting propane cylinders need to be sourced and connected separately, as is typical across this entire category.

Pros:

• ✅ Trusted trade brand with genuine workshop-grade build quality
• ✅ Propane fuel handles colder conditions more consistently
• ✅ Integrated stand improves stability and floor clearance

Cons:

• ❌ Propane cylinder and regulator not included in the box
• ❌ Best suited to well-ventilated spaces rather than sealed rooms

At around £50-£60, this offers genuinely strong value for a trade-grade propane heater — arguably the best pounds-per-BTU figure on this entire list.

3. Draper 07867 Free-Standing Propane Space Heater — best for durability and trusted branding

Another stalwart of the UK trade-tool market, Draper 07867 Free-Standing Propane Space Heater matches the Sealey on core specification — 15,354 BTU/4.5kW output — but comes from a brand with an equally long reputation for durability across garages, workshops, and building sites nationwide.

The free-standing design prioritises stability over compactness, which is a sensible trade-off for a heater that’s likely to sit in one spot for the duration of a work session rather than being carried room to room constantly. Here’s what to weigh: propane heaters like this one generally produce more heat per kilogram of fuel than butane, but the trade-off is that propane performs less predictably at very low ambient temperatures in unheated storage compared with keeping cylinders somewhere slightly warmer — a detail worth knowing if your garage genuinely drops below freezing overnight.

This suits anyone who wants a “buy it once” heater that will realistically outlast several cheaper alternatives — Draper’s reputation in the trade sector is built on exactly that kind of longevity. Aggregated review sentiment across Draper’s space heater range consistently highlights robust build quality and dependable ignition, with occasional mentions that the unit runs warm to the touch on its casing, which is standard for radiant heaters of this type and not unique to this model.

Pros:

• ✅ Long-established trade brand known for build longevity
• ✅ Strong 4.5kW output matches pricier alternatives
• ✅ Free-standing design suited to stationary workshop use

Cons:

• ❌ Less convenient to carry around than compact cabinet models
• ❌ Casing gets genuinely hot during use — care needed around it

At around £70-£90, it sits a little above the Sealey on price for essentially comparable output, with the difference coming down to brand preference and finer build details rather than a dramatic performance gap.

4. WARMGLOW Portable Gas Heater — best for wheeled mobility

Mobility is the clear priority with WARMGLOW Portable Gas Heater, which ships with wheels specifically so it can be rolled between the garage, the shed, and even indoors without needing to be lifted each time. At 4.1kW with three distinct heating settings, it’s comparable in raw output to the ELPINE cabinet heater but adds genuine ease of movement.

The built-in oxygen depletion sensor (ODS) is a meaningful safety feature worth calling out specifically — it automatically shuts the heater off if oxygen levels in the room drop too low, which is a genuinely important safeguard for any unflued gas appliance used in an enclosed space. Based on the spec comparison with cheaper cabinet heaters, the wheeled base and grey finish also read as more deliberately designed for regular repositioning rather than a “set it down once” appliance.

This is the pick for anyone splitting their time between a garage, a workshop, and maybe an outbuilding, who doesn’t want to wrestle a heavy cabinet heater across gravel or a step each time. Reviewer sentiment across similar WARMGLOW models consistently praises the ODS safety sensor and the ease of movement on wheels, with a recurring note that, like most butane units, three heat settings still cap out below what a comparably priced propane trade heater can deliver.

Pros:

• ✅ Wheeled base makes repositioning genuinely effortless
• ✅ Built-in oxygen depletion sensor for enclosed-space safety
• ✅ Three heat settings offer useful flexibility

Cons:

• ❌ Butane output caps lower than similarly priced propane units
• ❌ Wheeled base adds bulk versus compact cabinet designs

Priced around £70-£90, the added mobility and ODS safety feature justify sitting slightly above the cheapest cabinet heaters on this list.

5. Straame Mobile Gas Heater — best for compact storage between uses

Straame Mobile Gas Heater takes a different approach to portability — rather than wheels for moving it around while assembled, it folds down for storage, which matters enormously if garage space is tight and the heater needs to live on a shelf or in a cupboard between uses rather than taking up permanent floor space.

At 4.2kW with push-button ignition, it’s competitive on output with the other butane options here, and the foldable frame doesn’t come at the cost of stability once it’s set up and running — anti-tilt protection is a standard inclusion across this style of heater. What the spec sheet doesn’t fully convey is how much of a difference a genuinely quick, tool-free fold-flat design makes for anyone who only wants the heater out occasionally rather than as a permanent garage fixture.

This suits someone with a smaller garage or a shared workshop space where floor room genuinely matters, more than someone with a dedicated, spacious workshop where storage isn’t a constraint. Reviewer sentiment on similar foldable Straame-branded heaters consistently highlights the ease of collapsing the unit down and the push-button ignition working reliably straight out of the box, with occasional mentions that the anti-tilt base takes up slightly more footprint when fully deployed than expected.

Pros:

• ✅ Genuinely folds flat for compact, tidy storage
• ✅ Push-button ignition removes the fiddle of manual lighting
• ✅ Anti-tilt protection built into the design

Cons:

• ❌ Deployed footprint is larger than the folded size suggests
• ❌ Still requires separately sourced butane cylinders

At around £80-£100, it sits mid-pack on price, with the fold-flat storage design being the genuine differentiator worth paying for if space is tight.

6. CAMPLUX Nano Portable Gas Heater — best lightweight pick for occasional use

Where most heaters on this list are built for regular workshop sessions, CAMPLUX Nano Portable Gas Heater is explicitly engineered around genuine lightness and compactness — at 2.34kW with two-stage, 360-degree outdoor-capable heating, it’s positioned closer to a camping and occasional-use heater that also happens to work well in a garage than a dedicated workshop appliance.

The two-stage output and 360-degree heat spread mean it warms a small area evenly rather than throwing heat in one direction only, which suits sitting it on a workbench rather than mounting it in a fixed corner. Tip-over protection and an oxygen depletion sensor are both included, matching the safety features found on considerably pricier units, which is a genuinely strong inclusion at this compact size and price point.

Here’s what to weigh: this is not the heater for warming a full double garage through a cold snap — its comparatively modest 2.34kW output is honestly better suited to occasional-use heating, quick jobs, or supplementing another heat source, rather than serving as a garage’s sole heating solution. Reviewer sentiment consistently praises the genuinely compact, lightweight build and the inclusion of proper safety sensors at this size, with a recurring theme that buyers expecting workshop-scale heat output specifically found the lower kW rating limiting for larger spaces.

Pros:

• ✅ Genuinely compact and lightweight for easy transport
• ✅ 360-degree heat spread warms evenly from one position
• ✅ Includes both ODS and tip-over protection as standard

Cons:

• ❌ Lower 2.34kW output struggles in larger, colder garages
• ❌ Not intended as a sole heat source for extended sessions

At around £90-£100, this is a premium price for the output on paper, but the safety features and genuine portability justify it for anyone prioritising occasional-use heating over raw power.

7. Mr. Heater Portable Buddy — best for small-cylinder mobility and safety tech

Mr. Heater Portable Buddy brings a well-established American brand’s cylinder-fed design to the UK market, running on small 1lb propane cylinders rather than the larger bottles most other heaters on this list require — a genuinely different approach to cylinder-fed heaters that prioritises grab-and-go convenience over maximum runtime.

Rated at 9,000 BTU (roughly 2.6kW) with a piezo ignition system, it includes both an oxygen depletion sensor and a tip-over safety shut-off as standard — a combination of safety tech that’s noticeably more comprehensive than most butane cabinet heaters at a similar price. The fold-down handle and swivel-out regulator connection are small design details that add up to genuinely easier one-handed carrying between the house, garage, and shed.

This is the pick for anyone who values compact mobility and layered safety features over maximum heat output — the smaller cylinder format means shorter runtime per fuel change than a full-size propane bottle, but the trade-off is a genuinely lighter, more grab-and-go unit. Aggregated review sentiment is strongly positive and unusually consistent for a heater in this category, with buyers repeatedly highlighting the reliable piezo ignition and the reassurance of both an ODS and tip-over shutoff working as advertised, alongside occasional comments that small 1lb cylinders need replacing more frequently than a full-size bottle.

Pros:

• ✅ Comprehensive safety tech — ODS plus tip-over shutoff
• ✅ Small cylinder format makes it genuinely easy to carry
• ✅ Well-established brand with a large, consistent review base

Cons:

• ❌ Small 1lb cylinders need replacing more often than bottles
• ❌ Lower BTU output than the trade-grade propane heaters here

At around £95-£110, it’s toward the top of this list on price, but the combination of safety features and genuine one-handed portability makes a strong case for anyone prioritising mobility.

Practical Usage Guide: Getting Set Up Safely and Efficiently

Before lighting any portable gas heater for the first time, check the hose and regulator connection is fully seated and give it a visual once-over for cracks or perishing, especially if the unit or cylinder has been in storage over summer. Always connect the cylinder outdoors or in a well-ventilated space rather than in a sealed room, and only ever change cylinders with the heater switched off and cooled down.

Once running, position the heater at least a metre from anything flammable — sawdust, paint tins, and stacked cardboard are all common garage hazards that don’t always register as “flammable” until it’s too late. A common mistake in the first month of ownership is closing up the garage completely to “keep the heat in” — unflued gas heaters need a genuine, ongoing supply of fresh air to burn safely, so crack a window or door rather than sealing the space entirely.

For maintenance, wipe down the burner and any dust build-up between uses, store cylinders upright in a cool, ventilated spot away from direct sunlight, and never store a part-used cylinder inside the house itself. A basic carbon monoxide alarm, positioned at head height in the space where the heater’s used, is a genuinely inexpensive addition that adds real peace of mind for a cost of a few pounds.

Real-World Scenarios: Matching the Heater to How You Actually Use Your Garage

Consider Tom, who uses his garage as a weekend workshop for restoring furniture, spending three or four hours out there most Saturdays through winter. For him, the sustained, colder-weather-friendly output of the Sealey Space Warmer LP14 or Draper 07867 Free-Standing Propane Space Heater makes far more practical sense than a smaller butane unit that might struggle to keep pace across a long session.

Then there’s Aisha, who only pops into her garage for ten or fifteen minutes at a time to grab tools or deal with the recycling, and occasionally wants some quick warmth rather than a fully heated space. The CAMPLUX Nano Portable Gas Heater or Mr. Heater Portable Buddy suit her far better — lightweight, genuinely quick to fire up, and appropriately scaled for occasional-use heating rather than sustained sessions.

Finally, picture Rob, who splits his time between a garage and a separate garden shed and doesn’t want to buy two heaters. The wheeled WARMGLOW Portable Gas Heater or the fold-flat Straame Mobile Gas Heater solve exactly that mobility problem, letting him move one unit between spaces without much hassle.

Problem → Solution: Fixing the Most Common Portable Gas Heater Complaints

Problem: the heater won’t hold a consistent flame in colder conditions. This is typically a propane-versus-butane issue — butane struggles to vaporise properly below around 2-4°C, so switching to a propane-fuelled unit like the Sealey Space Warmer LP14 genuinely solves this for cold-weather use.

Problem: it’s a hassle to move between the garage and shed. Prioritise mobility features specifically — the wheeled WARMGLOW Portable Gas Heater or the genuinely lightweight Mr. Heater Portable Buddy are built exactly for this, rather than trying to make a stationary trade heater do a job it wasn’t designed for.

Problem: there’s no space to permanently store a heater. A fold-flat design like the Straame Mobile Gas Heater solves this directly, collapsing down for a shelf or cupboard rather than occupying permanent floor space.

Problem: worry about safety in an enclosed space. Choose a unit with a built-in oxygen depletion sensor as standard — the CAMPLUX Nano Portable Gas Heater and Mr. Heater Portable Buddy both include this, and it should be treated as a non-negotiable feature rather than a nice-to-have.

Problem: running costs feel higher than expected. Larger propane bottles generally offer a lower cost per kWh of heat than small disposable butane canisters or the 1lb cylinders used by compact units — if you’re heating regularly rather than occasionally, a full-size propane bottle paired with something like the Draper 07867 Free-Standing Propane Space Heater will usually work out cheaper over a season.

Your Buyer’s Decision Framework

If your garage sees regular, multi-hour sessions through a genuinely cold winter, choose Sealey Space Warmer LP14 or Draper 07867 Free-Standing Propane Space Heater, because propane’s cold-weather performance and higher output suit sustained use. If you need to move the heater between spaces regularly, choose WARMGLOW Portable Gas Heater for its wheels or Mr. Heater Portable Buddy for its lightweight, carry-friendly design. If floor space is genuinely tight, choose Straame Mobile Gas Heater for its fold-flat storage. If you only need occasional-use heating for short bursts rather than sustained warmth, choose CAMPLUX Nano Portable Gas Heater, because its lower output and lighter build match that use case honestly rather than being overkill. And if budget is the single overriding priority, choose ELPINE Portable Calor Gas Heater, accepting the trade-off of lower efficiency for the lowest realistic entry price on this list.

Butane vs Propane Garage Heaters: What Actually Changes

The butane garage heater versus propane debate isn’t marketing spin — it reflects a genuine physical difference between the two gases. Butane stops vaporising properly at temperatures below roughly 2-4°C, which means a butane heater can genuinely struggle to ignite or maintain a strong flame on a cold garage floor in deep winter, exactly when you need it most. Propane, by contrast, continues to vaporise reliably down to around -40°C, making it the more dependable choice for anyone heating an unheated space through genuinely cold conditions.

In practice, this translates into a simple rule of thumb: butane heaters like the ELPINE Portable Calor Gas Heater, WARMGLOW Portable Gas Heater, and Straame Mobile Gas Heater are perfectly adequate for autumn evenings, mild winter days, or garages that see some ambient warmth from an adjoining house wall — but on a genuinely freezing night, a propane unit like the Sealey Space Warmer LP14 or Draper 07867 Free-Standing Propane Space Heater will simply perform more reliably. Propane also tends to burn slightly hotter per unit of fuel, which is part of why the two propane trade heaters on this list post the highest BTU figures despite being competitively priced. Neither gas is inherently “better” — the right choice depends entirely on how cold your garage genuinely gets and how long you plan to run the heater each session.

How to Choose a Portable Gas Garage Heater Under £150

1. Decide between butane and propane based on your coldest realistic use case. If your garage regularly drops near freezing, propane’s cold-weather reliability matters more than any other single spec.
2. Match kW output to your garage’s actual size. A single-car garage rarely needs more than 4-4.5kW; oversizing wastes fuel without meaningfully improving comfort.
3. Check for a built-in oxygen depletion sensor (ODS) as a baseline requirement. This should be treated as essential rather than optional for any unflued gas heater used indoors.
4. Weigh mobility features against how often you’ll actually move it. Wheels and fold-flat designs add genuine value if you split time between spaces; they’re wasted cost if the heater lives in one spot.
5. Factor in cylinder cost and availability alongside the heater’s sticker price. A cheaper heater running on hard-to-find or expensive cylinders can cost more overall than a pricier unit with cheap, widely available fuel.
6. Read aggregated review sentiment for ignition reliability specifically. A heater that lights first time, every time, is worth more in practice than a marginally higher BTU rating.
7. Confirm tip-over protection is included. A garage floor is rarely perfectly flat, and this feature genuinely matters for safety around tools, vehicles, and foot traffic.

Cylinder-Fed Heaters vs Disposable Canister Heaters

Most heaters on this list are cylinder-fed, connecting via a hose and regulator to a refillable or exchangeable gas bottle — this is the standard, cost-effective format for anything used regularly, since larger cylinders work out cheaper per kWh of heat than small disposable options. The Mr. Heater Portable Buddy sits at the smaller end of this category, using compact 1lb propane cylinders rather than a full-size bottle, which trades some running cost efficiency for genuinely superior portability and quicker cylinder changes.

Disposable canister-style heaters — smaller camping-oriented units not featured in this list’s main seven — use sealed, non-refillable gas canisters that are convenient for occasional emergency use but become expensive quickly with regular use, since you’re paying for new canisters rather than simply refilling or exchanging a bottle. For a genuine portable gas garage heater used more than a handful of times a season, a cylinder-fed design connected to a standard exchangeable bottle — as with the Sealey Space Warmer LP14, Draper 07867 Free-Standing Propane Space Heater, or the butane cabinet options here — will almost always work out more economical over time than repeatedly buying small disposable canisters.

What to Expect: Real-World Performance and Mobility

On paper, kW and BTU figures rarely translate directly into what you’ll feel standing in a cold garage, so here’s the practical version. Expect a butane cabinet heater in the 4-4.2kW range, such as the ELPINE Portable Calor Gas Heater or WARMGLOW Portable Gas Heater, to noticeably warm a single-car garage within 10-15 minutes, taking the edge off rather than making it genuinely toasty in the depths of winter. Propane units at 4.5kW like the Sealey Space Warmer LP14 perform similarly but hold that output more consistently as ambient temperature drops further.

Mobility genuinely changes the practical experience of ownership more than most buyers expect before purchasing. A wheeled or fold-flat design isn’t just a convenience feature — it’s the difference between a heater that actually gets used regularly across multiple spaces and one that ends up permanently parked in a single corner because moving it feels like too much hassle. The Mr. Heater Portable Buddy, weighing noticeably less than the trade-grade propane units, is the clearest example here: its smaller cylinder format sacrifices some runtime, but in exchange it genuinely gets picked up and carried rather than left behind.

Portable Gas Heaters for Occasional-Use Heating

Not every garage needs — or benefits from — a heater built for sustained, all-day operation. For genuine occasional-use heating, where the goal is a quick blast of warmth for a short task rather than hours of comfortable working temperature, a smaller, lighter unit is usually the smarter buy rather than the most powerful option available. The CAMPLUX Nano Portable Gas Heater, with its lower 2.34kW output and genuinely compact build, is specifically suited to this pattern of use, as is the Mr. Heater Portable Buddy with its quick-swap small cylinder format.

Buying a full-scale trade heater for occasional ten-minute sessions is a classic mismatch between product and use case — you’ll pay more upfront, store a bulkier unit, and likely still wait longer for meaningful warmth than a compact model designed around exactly that shorter, lighter pattern of use. If your honest usage pattern is “in and out quickly, a few times a week” rather than “settled in for a long session,” lean toward the lighter, lower-output end of this list rather than assuming more power automatically means better value.

Safety, Ventilation & Carbon Monoxide Compliance Guide

Every unflued portable gas heater — regardless of brand, fuel type, or price — produces carbon monoxide as a by-product of combustion, and adequate ventilation is genuinely non-negotiable rather than a nice-to-have precaution. The Health and Safety Executive’s official guidance on domestic gas safety confirms that any gas appliance needs a reliable supply of fresh air to burn safely and to allow combustion products to disperse rather than accumulate in an enclosed space.

Carbon monoxide is entirely colourless and odourless, which is precisely what makes it dangerous — you won’t smell a build-up before symptoms start. As Wikipedia’s overview of carbon monoxide poisoning explains, early symptoms are often mistaken for flu or general tiredness, including headache, dizziness, and nausea, which is exactly why relying on symptoms alone to detect a problem is not a safe strategy. A dedicated carbon monoxide alarm, positioned in the space where the heater is actually used, is a small investment that closes this detection gap.

Practical rules worth following every single time: never run a portable gas heater in a fully sealed room, never leave one unattended while lit, always allow genuine airflow (a slightly open window or door, not just a closed room with an extractor fan), and if anyone using the space starts experiencing unexplained headaches, dizziness, or nausea that improve after leaving, treat that as a serious warning sign rather than a coincidence — as NHS guidance on carbon monoxide safety makes clear, symptoms that ease away from the source and return on re-exposure are a classic indicator worth taking seriously and acting on immediately.

Frequently Asked Questions

Conclusion

A cold garage doesn’t have to stay that way, and the good news is that solving it doesn’t require an expensive installation or a big spend — every genuine option on this list sits comfortably under £150, and the real decision is less about budget and more about matching fuel type, output, and mobility to how you actually use the space. Whether that’s the trade-grade reliability of the Draper 07867 Free-Standing Propane Space Heater, the genuinely portable Mr. Heater Portable Buddy, or the honestly-scaled CAMPLUX Nano Portable Gas Heater for quick occasional sessions, the right pick comes down to being realistic about your typical garage session rather than simply buying the highest BTU figure available.

Whatever you choose, treat ventilation and a carbon monoxide alarm as part of the purchase rather than an afterthought — that’s the one part of this decision that genuinely isn’t optional. Get the fuel type, output, and safety features right for your space, and a portable gas garage heater earns its keep within the first cold weekend you use it.
