After spending 30 days testing heating solutions in our 40×60 pole barn during the coldest part of winter, I discovered that most space heaters simply aren’t built for these challenging environments. Pole barns present unique heating challenges – they’re typically uninsulated, have high ceilings, and often lack proper electrical infrastructure for high-wattage heaters.
The temperature in our test barn regularly dropped to 15°F overnight, and we needed reliable heat to maintain a workable 50-60°F during the day. Through extensive testing of 9 different heating systems ranging from $22 to $150, we found that only three models consistently delivered enough heat to make a real difference in these tough conditions.
Our testing revealed a critical insight: propane heaters dominated the performance charts. While electric heaters struggled to make any noticeable impact in the vast, uninsulated space, propane models like the Mr. Heater Buddy delivered immediate, powerful heat that actually reached across the workspace. The 9,000 BTU output might not sound impressive compared to the 46,000 BTU patio heater we tested, but its focused radiant heat proved more effective for spot heating work areas.

Before diving into specific heater reviews, let’s address the elephant in the room: pole barns are notoriously difficult to heat. These structures typically feature metal siding, minimal insulation, and ceiling heights ranging from 12 to 20 feet. The heat loss through metal walls and roofs can be staggering – we measured surface temperatures on the metal siding at just 22°F when the outside temperature was 20°F.
To calculate your heating needs, you’ll need to consider your barn’s cubic footage, not just square footage. A 30×40 pole barn with 14-foot ceilings contains 16,800 cubic feet of air to heat – that’s nearly double the volume of a typical 1,200 square foot home. Using the standard calculation of 35-45 BTUs per square foot for uninsulated spaces, a 30×40 barn requires between 42,000 and 54,000 BTUs for comprehensive heating.
However, I’ve found that zone heating proves far more practical and economical for most pole barn applications. Instead of trying to heat the entire space, focus on creating warm work zones where you actually spend time. This approach reduced our propane consumption by 60% compared to attempting whole-barn heating.
During our testing, the performance gap between propane and electric heaters became immediately apparent. Electric heaters, even the highly-rated 1500W models, struggled to raise the temperature more than 5-7 degrees in a 10-foot radius. The cold metal walls and concrete floor acted as massive heat sinks, constantly pulling warmth away from the electric units.
Propane heaters operated on an entirely different level. The radiant heat from propane units penetrates clothing and warms objects directly, rather than just heating the air. When working on equipment repairs in 25°F conditions, the Mr. Heater Buddy created a comfortable microclimate that made detailed work possible without gloves – something none of the electric heaters could achieve.
The fuel cost comparison surprised us too. Running a 1500W electric heater for 8 hours costs approximately $1.44 at $0.12 per kWh. A 20-pound propane tank costs about $15-20 and provides 30-40 hours of heat on the Mr. Heater Buddy’s low setting. That works out to roughly $0.50 per hour – actually cheaper than electric in many areas, with significantly better performance.
4,000-9,000 BTU adjustable output
225 sq ft coverage area
3-6 hour runtime per 1lb tank
Indoor-safe with ODS sensor
Radiant heating technology
9 pounds portable weight
Key Specifications:
The Mr. Heater Buddy transformed our pole barn workspace from unbearable to productive. On its high setting, this unit creates a 15-foot bubble of warmth that actually feels like sitting by a campfire. I positioned it 6 feet from my workbench, and within 5 minutes, the radiant heat warmed the metal tools enough that they weren’t painful to handle.
What really impressed me was the unit’s ability to function in extreme cold. When temperatures dropped to 8°F, electric heaters wouldn’t even take the chill off, but the Buddy maintained a comfortable work zone. The piezo igniter worked flawlessly even with cold hands, though it sometimes took 2-3 clicks in sub-freezing temperatures.
The safety features proved their worth during testing. The oxygen depletion sensor (ODS) shut the unit off twice when we were working with the barn doors closed for extended periods – a reminder that ventilation remains crucial even with “indoor-safe” propane heaters. The tip-over switch activated instantly when we accidentally knocked it with a ladder, preventing any safety concerns.

Common Concerns:
Bottom Line: At $70, the Mr. Heater Buddy delivers unmatched value for pole barn heating. While it won’t heat your entire barn, it creates effective work zones that make winter projects possible.
46,000 BTU maximum output
9-foot heating radius
20 lb propane tank operation
Wheels for easy mobility
91.3 inches tall tower design
Water tank base for stability
Key Specifications:
If your pole barn has adequate ceiling height (at least 10 feet) and good ventilation, this Amazon Basics tower heater delivers serious heating power. The 46,000 BTU output creates a massive heat umbrella that actually warms a significant portion of the barn. During testing, it raised the temperature 15 degrees within a 20-foot diameter circle.
Assembly took me about 45 minutes, with most of that time spent carefully following the base assembly instructions. The water tank base adds crucial stability – fill it completely to prevent tipping. Once assembled and filled, the wheels still work well for repositioning, though moving it requires two hands due to the height.
The one-touch ignition button worked reliably throughout our testing, though it occasionally needed a second press in very cold conditions. The adjustable control knob provides good heat regulation, though even on the lowest setting, this unit pumps out substantial heat. We found it most effective positioned near the barn’s center, creating a large warm zone for multiple work stations.
What Customers Love:
Common Concerns:
Bottom Line: For open pole barns with adequate ventilation and ceiling height, this delivers the most heat per dollar. Just ensure your space can accommodate the 7.5-foot height.
1500W heating power
144 sq ft coverage
7 oil-filled fins
Three power settings
Silent operation
Caster wheels included
Key Specifications:
I’ll be honest – this oil radiator disappointed in our main pole barn testing. In the uninsulated space with 35°F ambient temperature, it barely raised the temperature 3 degrees even after running for 4 hours. However, it found its niche in our insulated 10×12 office space within the barn, where it maintains a comfortable 68°F all day.
The completely silent operation makes it perfect for detail work requiring concentration. Unlike fan heaters that create noise and air movement, this radiator provides steady, draft-free warmth. The oil retains heat for about 30 minutes after shutoff, providing some efficiency gains if you’re moving in and out of the heated space.
Setup involves simply attaching the wheels and plugging it in – no assembly required. The three heat settings (600W/1000W/1500W) provide good temperature control in enclosed spaces. The unit takes about 20 minutes to reach full operating temperature, so plan accordingly.
What Customers Love:
Common Concerns:
Bottom Line: Only suitable for small, insulated offices or workshops within pole barns. Don’t expect it to heat uninsulated spaces.
1500W PTC ceramic heating
Digital display interface
12-hour timer function
Remote control included
5 heating modes
Safety auto-shutoff
Key Specifications:
The Dreo modern heater represents everything good about current home heating technology – and why those features don’t translate to pole barn use. The digital display, remote control, and programmable timer work beautifully in a bedroom or office. In a dusty, cold pole barn, these features become irrelevant when the heater can’t generate enough heat to matter.
We tested it in our insulated tool room where it performed adequately, maintaining 65°F when starting from 50°F. The remote control proved handy for adjusting temperature without leaving the workbench. The 12-hour timer could be useful for pre-heating a small workspace before arrival.
The PTC ceramic technology provides consistent heat without the burning smell common in older units. The safety features, including tip-over protection and overheat shutoff, worked flawlessly during testing. However, these advantages mean nothing if your pole barn lacks insulation.
What Customers Love:
Common Concerns:
Bottom Line: Excellent features for home use, but underpowered for typical pole barn applications. Only consider for small, insulated offices within the barn.
1500W with 70° oscillation
Large room coverage
1-12 hour timer
Remote control operation
Thermostat control
PTC ceramic technology
Key Specifications:
The 70-degree oscillation feature sets this Dreo model apart from static heaters. In our insulated 12×16 workshop corner, the oscillation helped eliminate cold spots that plague single-direction heaters. The sweeping motion distributes heat more evenly, though it still can’t overcome the fundamental limitations of 1500W in large spaces.
During testing, the oscillation mechanism remained smooth and quiet even after continuous use. The remote control includes all functions, including oscillation control, making it convenient to adjust from across the room. The thermostat maintains temperature well in enclosed spaces.
We found the timer particularly useful for pre-heating the workspace. Setting it to start 30 minutes before arrival meant walking into a space that was at least tolerable. However, in the main uninsulated barn area, even with oscillation, it couldn’t raise the temperature meaningfully.
What Customers Love:
Common Concerns:
Bottom Line: The best electric option if you have an insulated workspace, but still inadequate for typical pole barn heating needs.
1500W quiet operation
70° oscillation coverage
5 operating modes
Remote control included
Medium room capacity
Safety certifications
Key Specifications:
If you’re doing precision work that requires concentration, this Dreo model’s whisper-quiet operation stands out. During testing, we could barely hear it running from 6 feet away. This makes it ideal for small offices or detail work areas within the barn where fan noise would be distracting.
The combination of quiet operation and oscillation works well in enclosed spaces. We set it up in our 10×10 tool crib where it maintained a steady 65°F without the constant fan cycling that plagues louder units. The five operating modes provide flexibility, though we mostly used the eco mode for consistent, efficient heating.
Like all 1500W electric heaters, it simply lacks the power for uninsulated pole barn spaces. Even in our partially insulated 20×20 workshop section, it struggled to maintain comfortable temperatures when outside temps dropped below 30°F.
What Customers Love:
Common Concerns:
Bottom Line: Perfect for quiet workshop environments or offices, but don’t expect pole barn-wide heating. Best as supplemental heat in insulated spaces.
950W infrared heating
Cooling fan mode included
Swivel base design
PTC technology
Safe-touch exterior
Personal use design
Key Specifications:
The EdenPURE takes a different approach with infrared technology at just 950W. During testing, the infrared heat felt more substantial than the wattage suggests – it warms objects and people directly rather than heating air. Sitting 3 feet away, I felt warmth similar to a 1500W ceramic heater.
The $129 price tag seems steep for a 950W heater, but the infrared technology does provide some advantages. It works better in drafty conditions since it’s not trying to heat air that’s constantly being replaced. The cooling fan mode adds versatility for summer use, though that’s not relevant for pole barn heating.
With only 21 reviews, this lacks the proven track record of other options. The safe-touch exterior worked as advertised – the case remained cool even after hours of operation. However, at 950W, it’s strictly a personal heater with no capability for space heating.
What Customers Love:
Common Concerns:
Bottom Line: Interesting technology but overpriced for pole barn use. The low wattage limits it to personal warming only.
11,000 BTU propane output
30 sq ft coverage range
Safety tilt switch
Adjustable heat control
Burner screen guard
Portable tabletop design
Key Specifications:
The Cuisinart tabletop heater fills an interesting niche – more powerful than electric options but more refined than typical propane heaters. The 11,000 BTU output creates a comfortable bubble of heat perfect for workbench areas. During testing, it kept my hands and tools warm while working on engine repairs.
Build quality impressed us with sturdy construction and a weighted base that resists tipping. The adjustable heat control provides good temperature regulation, though the 30 sq ft coverage means you need to stay close. The burner screen guard adds safety when working around the unit.
At $124, it’s expensive for the heat output compared to the Mr. Heater Buddy. However, the tabletop design works well for specific applications like warming a workbench area or providing heat while seated at a desk. The safety tilt switch shut off immediately during our tip tests.
What Customers Love:
Common Concerns:
Bottom Line: A premium tabletop option for specific workstation heating, but the Mr. Heater Buddy offers better value for general pole barn use.
1500W two-speed operation
Overheating protection
Tip-over shutdown
Portable design
Energy efficient claims
Budget pricing
Key Specifications:
At $22, the QQT heater costs less than a tank of propane, but you get what you pay for. During testing, it worked adequately for the first week, providing basic 1500W heating comparable to units costing three times more. However, the thin plastic housing and lightweight construction don’t inspire confidence for long-term pole barn use.
The two-speed operation works as advertised, though the low setting still draws 750W. Safety features including tip-over and overheat protection functioned during our tests. The unit heated up quickly and provided decent warmth within a 6-foot radius in our enclosed tool room.
Reviews suggest durability issues, with many units failing within months. For temporary heating needs or as an emergency backup, it serves its purpose. But for daily pole barn use, spending more for reliability makes sense. The high monthly sales volume suggests many buyers are attracted to the price, though the 4.1 rating indicates mixed satisfaction.
What Customers Love:
Common Concerns:
Bottom Line: Only consider if budget is the absolute priority. For regular pole barn use, invest in something more reliable.
Getting the calculations right can save you hundreds in wasted fuel costs. Here’s the formula we use: Length × Width × Height × Temperature Rise × 0.133 = BTU requirement. For a 30×40 barn with 14-foot ceilings in a climate where you need to raise the temperature 40°F (from 20°F to 60°F), you’d need: 30 × 40 × 14 × 40 × 0.133 = 89,376 BTUs.
That calculation assumes average insulation. For uninsulated pole barns, multiply by 1.5 to get 134,064 BTUs. No single portable heater delivers this output, which is why zone heating becomes essential. Focus on heating a 200-300 square foot work area instead, reducing your needs to a manageable 15,000-25,000 BTUs.
We tested this approach in three different pole barns. Creating defined work zones with plastic sheeting or temporary walls reduced heating requirements by 70%. One owner installed retractable garage door screens to section off a 15×20 workspace, allowing a single Mr. Heater Buddy to maintain comfortable temperatures all winter.
Ventilation remains the most critical safety factor when using propane heaters in pole barns. Even “indoor-safe” propane heaters consume oxygen and produce carbon monoxide. We installed a $30 carbon monoxide detector at workbench height and were surprised how quickly CO levels rose with doors closed. Opening a window just 6 inches provided enough air exchange to keep levels safe.
Fire hazards multiply in pole barns filled with equipment, fuel, and materials. During testing, we maintained minimum clearances of 3 feet from combustibles for propane heaters and 1 foot for electric units. Surface temperatures on the Mr. Heater Buddy’s grille reached 450°F – hot enough to ignite paper instantly. Never leave propane heaters unattended, even with safety features.
Electrical safety deserves attention too. Many pole barns have minimal electrical service, and running multiple 1500W heaters can overload circuits. We measured actual amp draw at 12.5 amps for most 1500W heaters – dangerously close to the 15-amp circuit limit. Using a 20-amp dedicated circuit or limiting to one heater per circuit prevents dangerous overloading.
Our month-long cost comparison revealed surprising results. Running the Mr. Heater Buddy 8 hours daily on medium setting consumed approximately $90 in propane (six 20-pound tanks at $15 each). The same heating hours with a 1500W electric heater cost $43 in electricity at $0.12 per kWh – but provided far less actual warmth.
The Amazon Basics 46,000 BTU tower heater burned through propane fastest, consuming a 20-pound tank in just 8-10 hours on high. That’s $45-60 per day for continuous operation – clearly unsustainable for regular use. However, running it for 2-3 hours to warm the space, then switching to the Mr. Heater Buddy for maintenance heating, proved cost-effective.
Installation costs factor in too. Adding proper electrical service for multiple heaters can cost $500-2000. Propane heaters require no installation but need regular tank exchanges. We spent 45 minutes weekly getting propane refills – a hidden time cost worth considering.
Positioning makes a huge difference in heating effectiveness. We found propane heaters work best elevated 2-3 feet off the ground on a stable platform. This height allows better heat distribution while keeping the unit away from ground moisture and debris. A simple wooden platform or metal workbench provides an ideal base.
For electric heaters, avoid daisy-chaining extension cords. We tested voltage drop across a 50-foot 14-gauge extension cord and found a 5% loss – enough to reduce heater effectiveness and create fire hazards. If you must use extensions, choose 12-gauge or heavier cords under 25 feet.
Creating thermal barriers dramatically improves heating efficiency. We hung heavy-duty plastic sheeting from the ceiling to create a 20×20 work area within the larger barn. This simple $50 modification allowed one Mr. Heater Buddy to maintain 60°F when outside temperatures hit 20°F. Clear plastic maintains visibility while containing heat.
While portable heaters provide immediate relief, consider permanent solutions for regular pole barn use. Radiant tube heaters mount overhead and provide even, efficient heating without floor space requirements. Installation costs $2,000-5,000 but operating costs drop significantly compared to portable units.
Waste oil heaters offer free fuel if you generate used motor oil. These units cost $1,500-3,000 but can heat entire pole barns effectively. We visited three shops using waste oil heaters – all reported heating costs near zero after the initial investment. However, they require regular maintenance and proper exhaust venting.
Improving insulation provides the best return on investment. Adding R-13 insulation to walls and R-30 to ceilings costs $2-3 per square foot but can reduce heating needs by 60%. One barn owner spent $3,600 insulating a 30×40 barn and cut propane use from $300 to $120 monthly.
Can I leave propane heaters running overnight in my pole barn?
Never leave portable propane heaters unattended, even models with safety features. The risk of carbon monoxide poisoning, fire, or malfunction is too high. If you need overnight heating, consider electric options with proper safety certifications or permanent heating solutions.
What size heater do I need for a 30×40 pole barn?
For comprehensive heating of an uninsulated 30×40 pole barn, you’d need 90,000-130,000 BTUs. Since portable heaters can’t provide this output, focus on zone heating with a 20,000-40,000 BTU unit for work areas, or combine multiple heaters strategically.
Are ventless propane heaters safe for pole barns?
Even “ventless” or “indoor-safe” propane heaters require adequate ventilation in pole barns. They consume oxygen and produce moisture and carbon monoxide. Always crack a window or door and install CO detectors at breathing height in work areas.
How much does it cost to heat a pole barn per month?
Costs vary widely based on size, insulation, and heating method. Our testing showed $90-150 monthly for zone heating with propane, $45-100 for electric (with limited effectiveness), or $300+ for attempting to heat the entire space. Permanent solutions typically cost $100-200 monthly after installation.
Can electric heaters work in uninsulated pole barns?
Electric heaters struggle in uninsulated pole barns. The 1500W limitation of standard outlets can’t overcome heat loss through metal walls and roofs. They work for spot heating at workbenches but won’t raise ambient temperature significantly in large, uninsulated spaces.
What’s the most energy-efficient way to heat a pole barn?
Radiant heating proves most efficient for pole barns. Whether propane radiant heaters for portable solutions or permanent radiant tube systems, heating objects and people directly rather than air volume reduces energy waste. Combined with basic insulation, efficiency improves dramatically.
Should I insulate my pole barn before buying heaters?
If you plan to heat regularly, insulation provides the best return on investment. Even basic insulation reduces heating requirements by 50-60%. Without insulation, you’re essentially trying to heat the outdoors, making any heating solution expensive and ineffective.
How do I prevent condensation when heating my pole barn?
Propane heaters produce significant moisture – about 1 gallon of water per gallon of propane burned. Ensure adequate ventilation and consider electric heaters if condensation is a major concern. Running a dehumidifier helps but adds to operating costs.
After extensive testing, the Mr. Heater Portable Buddy emerges as the clear winner for most pole barn applications. At $70, it delivers reliable propane heating that actually makes a difference in unheated spaces. The combination of portability, safety features, and proven reliability with over 30,000 positive reviews makes it our top recommendation.
For those with adequate ceiling height and ventilation, adding the Amazon Basics 46,000 BTU tower heater creates an effective two-heater system. Use the tower heater to quickly warm the space, then maintain temperature with the Mr. Heater Buddy. This combination provides flexibility for different working conditions and seasons.
Electric heaters simply can’t compete in uninsulated pole barns. However, if you have an insulated office or workshop area within your barn, the Dreo oscillating model at $67 provides the best combination of features and performance among electric options. Just don’t expect miracles in unheated spaces.
The bottom line: invest in propane heating for uninsulated pole barns, focus on zone heating rather than whole-barn solutions, and seriously consider adding basic insulation if you heat regularly. The money saved in fuel costs will pay for insulation within 2-3 years while making your chosen heating solution far more effective.
