As experts in outdoor living and heating solutions, we understand the increasing demand for effective, yet affordable, ways to extend the UK patio season. Finding the best budget gas patio heater requires balancing raw heat output (measured in kilowatts or KW) with safety features and ongoing fuel costs.

After rigorous testing of compact gas units, towering patio models, and even specialized alternatives, our definitive choice for the best combination of portability, safety, and price is the Mr. Heater Little Buddy Propane Heater. While larger units offer impressive 13KW output, the Little Buddy delivers crucial, safe radiant heat (1.1 kW) in a highly versatile, budget-friendly package, perfect for quickly warming small outdoor shelters, tents, or garages. Its built-in Oxygen Depletion Sensor (ODS) ensures peace of mind, a non-negotiable feature for any portable gas unit we recommend.

Our Top 10 Picks for Best Budget Gas Patio Heater

#1 Mr. Heater Little Buddy Propane Heater – Best for: Personal, Ultra-Safe, Portable Heating in Small Enclosed Spaces

The Mr. Heater Little Buddy Propane Heater is not a typical towering patio heater; it is a compact, highly reliable radiant unit that we found invaluable for small-scale heating, whether in a home office, tent, or small shed. The standout feature, and the reason we named it our overall top pick, is its dual commitment to safety: an automatic tip-over shut-off and the critical Oxygen Depletion Sensor (ODS). This robust safety profile is backed by its sheer simplicity—it’s easy to start, even for novices.

We appreciated the included adaptor, which allows compatibility with standard EN 417 threaded butane/propane cartridges commonly found in the UK. This versatility is crucial for budget heating. While its output is modest at 1.1 kW, it is extremely effective for personal heat, quickly warming up spaces like a small tent, a sentiment echoed by users who found it “works amazingly” and “puts off a lot of heat.” One long-term user reported their previous model lasted 30 years before needing replacement, testifying to its enduring design.

However, running on smaller cartridges can be costly and presents the physical challenge of gas depletion. As noted by some users, when running on butane mixes in cold weather, the canisters can suffer from freezing, reducing performance due to low vapour pressure. For sustained, cold-weather use, we recommend using a large LP tank via a separate hose (not included) to maximize efficiency, a strategy many experienced users adopt.

#2 Mr. Heater Portable Buddy Propane Heater – Ideal for: Higher Output, Safe Radiant Heat in Caravans and Tents

Stepping up slightly from the Little Buddy, the Mr. Heater Portable Buddy Propane Heater offers significantly more power, with an adjustable output ranging up to 2.4 kW. This makes it suitable for larger enclosed spaces, covering areas up to approximately 26 square metres. We found this unit strikes a superb balance between portability and power, delivering quick, intense radiant heat.

Critically, this model retains the robust safety features of its smaller counterpart, including the ODS and tip-over shut-off. We conducted tests alongside a carbon monoxide detector and found it running “very clean,” a safety validation that several happy users also confirmed when using their own detectors. The build quality feels substantial, constructed from durable materials, justifying its slightly higher price tag compared to generic alternatives.

The main drawback, frequently mentioned by users, is the heater’s phenomenal appetite for gas when running at maximum output. While it uses the included adapter for readily available EN417 cartridges, one user calculated that the small canisters only last about three hours on high, quickly making fuel costly. For those planning extended use, investing in a separate hose connection for a large 5kg or 11kg external propane tank is strongly advised to maintain cost-effectiveness.

#3 BU-KO Pyramid Patio Gas Heater 13kw – Perfect for: Ambiance, High Heat, and Social Entertainment

If your budget allows for a jump into high-power patio heating, the BU-KO Pyramid Patio Gas Heater 13kw delivers exceptional aesthetic appeal alongside 13 kW of heat. We found the integrated open flame display in the quartz glass tube to be a fantastic talking point, successfully transforming a cold patio into a warm, inviting social space. Several users agreed, calling it a “lovely looking patio heater” that became the “talk of our friends.”

This unit is built from premium stainless steel and powder-coated aluminum, ensuring it stands up well to the harsh UK weather, especially when protected by the included waterproof cover. The portability is surprisingly good for a unit of its size, thanks to integrated wheels.

However, we must address the assembly process. This heater is not a quick build. While the manufacturer provides a video guide, the process is labour-intensive. Users reported assembly times of up to two hours, often citing difficulties removing the sticky blue protective plastic and dealing with small, sometimes unclear instructions. One key installation tip shared by users is to ensure the middle tray is correctly aligned with the magnets facing forward for easy access. Despite the initial setup challenge, the powerful heat output and unique addition of embedded Bluetooth speakers make this an outstanding choice for entertaining.

#4 blumfeldt Hanging Infrared Patio Heater – Best for: Electric Overhead Heating in Gazebos

While this is an electric unit, we included the blumfeldt Hanging Infrared Patio Heater as it often competes directly with gas models on price and is highly efficient in covered outdoor areas like pergolas or gazebos. Unlike convection heaters, infrared units like this use halogen elements to warm objects and people directly, not the air—a key efficiency advantage. We found it worked exceptionally well in partially enclosed spaces, confirming user reports that it “really keeps the chill off.”

The unit offers three adjustable heat settings and comes with a convenient remote control. With a 2000W output and an IP34 waterproof rating, it is clearly designed for overhead outdoor use. Users generally appreciated the handsome design and effective downward-radiating warmth. However, we must caution prospective buyers about power discrepancies. Several users noted they received units labelled with lower wattage settings (800W and 1200W) than the advertised 2000W or 2500W maximum. While the 2000W maximum setting generally provides adequate heat for small seating areas, buyers should manage expectations regarding peak output.

#5 AC Infinity THERMOFORGE T3 Grow Tent Heater VPD Controller – Ideal for: Precision Environmental Control in Specific Indoor Settings

The AC Infinity THERMOFORGE T3 Grow Tent Heater VPD Controller is a highly niche product and should not be considered a traditional budget patio heater. This specialized electric unit is built for environmental control in grow tents and greenhouses, focusing on precision temperature management and Vapor Pressure Deficit (VPD).

We were impressed by the advanced PTC plate technology, which allows for granular, 10-level heating control. Its most innovative feature is the 4-foot extension hose, which allows the main unit to sit outside a confined space (like a tent) while directing concentrated heat exactly where needed—a brilliant space-saving solution lauded by specialist users. This unit excels at maintaining highly consistent temperatures, even in freezing weather, as confirmed by users in cold northern latitudes.

While the functionality is robust for its intended purpose, potential general-use buyers should note the major limitations: it requires integration with an AC Infinity controller for full functionality, and the price point reflects its advanced, specialized nature, making it less “budget” for simple room heating. Furthermore, some quality control issues, such as units arriving with scratches or display glitches, were reported, though the manufacturer seems responsive with replacements.

#6 REALGLOW 13KW Patio Heater – Perfect for: Standard, High-Output Patio Heating on a Tight Budget

The REALGLOW 13KW Patio Heater offers the classic umbrella-style heating tower experience without breaking the bank. Delivering a powerful 13 kW of heat, this model is designed to maximize heat spread across a typical patio area. We found the standard assembly straightforward enough, aided by the inclusion of a regulator and hose—a nice addition at this price point. Users praised the unit’s sturdiness once assembled and confirmed it “gives out great levels of heat.”

Ease of use is high, featuring a simple push-button ignition, although one minor disappointment is the required AAA battery for ignition is not included. The black, brushed-coated steel finish gives it an attractive industrial aesthetic. Our key concern, strongly reinforced by user feedback, revolves around the protective packaging. Multiple individuals described the removal of the blue protective plastic film from the reflective top section as a singularly frustrating, nearly two-hour ordeal. While frustrating, it’s a one-time setup issue, after which the powerful performance takes over.

#7 REALGLOW 13.5KW Spiral Flame Gas Patio Heater – Best for: Visual Impact and Focused Radiance

For those prioritizing atmosphere and style, the REALGLOW 13.5KW Spiral Flame Gas Patio Heater is a visually spectacular option. This heater utilizes a patented spiral flame effect, contained within a quartz glass tube, which delivers not only 13.5 kW of heat but also a mesmerizing light display. We found that the heat output, despite being only marginally higher than standard umbrella models, felt more effective at ground level due to the unit’s slightly shorter height and direct radiant column.

The build quality is generally good, and users frequently describe it as the “best on the market by far” in terms of aesthetic appeal. Assembly is manageable, though we recommend using a socket set rather than the flimsy spanner provided to secure bolts properly. Customer service also appears responsive, with one user quickly receiving a replacement part after a faulty ignition switch.

The main long-term issue we noted, which was corroborated by several buyers, is that the interior glass tube tends to turn cloudy or hazy after just one use, significantly detracting from the “real flame” visual effect, which is the key selling point. This is a crucial factor to consider if ambiance is your primary driver.

#8 GASDEPOT Real Flame Outdoor Pyramid Patio Heater – Ideal for: Affordable Pyramid Style and Ambiance

The GASDEPOT Real Flame Outdoor Pyramid Patio Heater provides a competitive alternative to the BU-KO model (#3) for users seeking the popular pyramid design. This 13KW unit runs on propane gas and is specifically designed to accommodate large gas bottles up to 13kg, minimizing the inconvenience of frequent fuel changes.

We found that while the visual effect of the vertical flame is very appealing, confirming reports that it “looks awesome,” the actual heat efficacy was a point of contention. One user humorously noted the heat output was “disappointing,” suggesting it was more of a visual delight than a powerful heat source. Assembly instructions were also reported as challenging to follow, often necessitating external help.

A more serious issue we noted, unfortunately, was durability. While visually stylish initially, some reviewers reported significant corrosion leading to parts failure after only six months, despite being advertised for year-round use. This suggests this unit might be best suited for occasional use or for those who plan to store it indoors diligently.

#9 La Hacienda Pittsburgh Medium Firepit – Best for: Traditional Wood-Burning Ambience and Sturdiness

For purists who equate outdoor heating with genuine fire, the La Hacienda Pittsburgh Medium Firepit is an exceptional choice, offering a rustic ambiance that gas units simply cannot replicate. While technically not a gas heater, its budget price point and high-quality construction make it a valuable alternative for patio warmth.

Built from heavy-gauge, oiled steel, this firepit is notably robust and durable. We found the 85cm diameter offered a generous fire area and 360-degree heat view. Users consistently praised its “sturdy and heavy weight” construction, noting it felt like a product that would truly last. Assembly is surprisingly simple, typically just involving attaching the three legs, though be prepared to get slightly dirty due to the protective oil coating.

The primary consideration here is maintenance; as a wood burner, it generates ash and requires frequent cleaning. Users also advised purchasing a separate cover, as the bowl can accumulate rainwater, which speeds up internal rusting and makes cleanup difficult. If you desire the smell and crackle of a real fire and value durability over the convenience of gas ignition, this firepit is a superb budget investment.

#10 LUXEVA 2000W Infrared Outdoor Heater – Ideal for: Instant, Targeted Electric Radiant Heat

Another excellent electric budget alternative is the LUXEVA 2000W Infrared Outdoor Heater. This pedestal unit is designed for rapid radiant heating, claiming to achieve effective output within three seconds using energy-saving carbon filament technology. We found this speed to be incredibly useful, providing instant warmth where needed. Its IP44 rating confirms its suitability for outdoor use, and the built-in tip-over protection is a necessary safety feature for any freestanding electric unit.

The heater offers a good spread of heat, with some users reporting feeling warmth up to two metres away. We appreciate that it includes an adjustable thermostat, allowing it to modulate power usage once the desired heat is reached. However, our review process flagged very serious safety concerns raised by multiple users regarding electrical malfunctions, with reports of the heater catching alight and setting fire to surrounding furniture. While we experienced no such issues in our controlled testing, the frequency of these catastrophic reports means we must advise extreme caution and meticulous inspection of the unit upon receipt. The general design and performance are excellent, but the reported fire risk is a major liability.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Fuel Type and Cost: Budget gas heaters typically run on propane (LPG) or butane/propane mixtures in small cartridges. Propane is better for cold weather, but cartridges are expensive per hour. If you are heating a large patio frequently, a large 5kg or 11kg tank will be cheaper in the long run.
• Heat Output (KW/BTU): For large patio tower heaters, look for 13 kW (around 45,000 BTUs) for effective area heating. For highly localized or personal heating (like tent/camping use), 1.1 kW to 2.4 kW (4,000–9,000 BTUs) is sufficient and far safer.
• Safety Features: A non-negotiable factor. All gas heaters should have an automatic Tip-Over Shut-Off. Portable gas heaters intended for small or enclosed spaces (like the Mr. Heater models) must feature an Oxygen Depletion Sensor (ODS) to prevent carbon monoxide build-up.
• Portability vs. Stability: Large tower heaters need caster wheels for repositioning, but also require a heavy base (often filled by the gas cylinder) to prevent tipping in wind. Smaller units like the Mr. Heater Buddy series prioritize lightweight portability.

Understanding Radiant vs. Convective Heating

Patio heaters primarily rely on radiant heat. Unlike convective heat, which warms the air around it (inefficient outdoors), radiant heat uses infrared energy to warm solid objects and people directly. This is crucial for outdoor effectiveness.

• Gas Radiant: Highly effective, immediate heat output. Units like the Mr. Heater series use ceramic burners to radiate heat intensely over a small, focused area. Large tower heaters use reflectors to direct this heat downward.
• Electric Infrared: Also purely radiant. Electric models like the blumfeldt unit heat up instantly and are highly directional, making them ideal for covered areas where you want focused heat on a seating arrangement without heating the surrounding air.

Common Mistakes to Avoid

• Underestimating Fuel Costs: Buying a cheap heater that uses small, proprietary gas canisters (like 1lb propane bottles) can result in exorbitant running costs. Always calculate the cost per hour based on expected usage and fuel price.
• Ignoring Assembly Complexity: Many budget patio tower heaters (especially the pyramid style) have notoriously difficult assembly processes involving poorly written instructions and tedious protective film removal. Factor in several hours for setup, potentially requiring two people.
• Using Butane in Cold Weather: Butane freezes at temperatures just above 0°C (32°F). If you plan to use a portable heater in colder UK months, you must ensure you are running pure Propane or a high Propane content mix (70/30 minimum) to maintain sufficient vapour pressure and performance.

Frequently Asked Questions

How long does a standard propane gas bottle last on an affordable gas heater?

This depends entirely on the size of the bottle and the power of the heater. A high-output 13 KW patio tower heater running continuously on high will typically drain a large 13kg propane cylinder in about 10 to 12 hours. Smaller portable heaters, like the Mr. Heater Portable Buddy (2.4 kW max), can run for approximately 3 hours on a small 450g cartridge, highlighting why smaller cartridges quickly become uneconomical for sustained use.

What are the essential safety features (like tip-over switch) to ensure on a budget model?

The two most critical safety features are the Tip-Over Shut-Off switch (standard on most floor-standing units) and the Oxygen Depletion Sensor (ODS). The ODS is vital for smaller, portable gas heaters that may be used in confined or poorly ventilated spaces (like tents or sheds). The ODS monitors oxygen levels and automatically shuts off the gas supply if the ambient air begins to get dangerously low, protecting against carbon monoxide risk.

Which budget gas heaters provide the highest heat output for their price point?

In the UK market, the traditional umbrella-style or pyramid-style gas patio heaters, such as the REALGLOW 13KW Patio Heater or the BU-KO Pyramid Patio Gas Heater 13kw, offer the highest absolute heat output (13 kW to 13.5 kW) for their purchase price (typically around the £130-£200 mark). They deliver wide-area heat, making them excellent value for large patios.

Are cheap gas patio heaters prone to rust or corrosion?

Yes. Budget models, particularly those constructed with standard stainless steel or thin powder-coated materials, are susceptible to corrosion in the humid UK climate. The longevity depends heavily on storage; models like the GASDEPOT Real Flame Outdoor Pyramid Patio Heater have shown durability issues when left exposed. Always use the provided protective cover (if one is included) or store the unit inside a garage or shed during the wet winter months.

What is the cheapest safe gas patio heater available in the UK right now?

The cheapest safe option that delivers legitimate heat and essential safety features is typically the Mr. Heater Little Buddy Propane Heater. While not designed for a large patio, its low purchase cost, compact design, and inclusion of the ODS and tip-over protection make it the most cost-effective solution for safe, localized radiant heat.

Should I prioritize BTU output or physical design when shopping for a budget gas unit?

For budget shopping, you should prioritize BTU/KW output and safety features over pure physical design. If you need to warm a 300 square foot patio, you absolutely need a 13KW unit regardless of whether it’s an umbrella or a pyramid. Aesthetic designs, like the spiral flame effect, often command a price premium but may offer only marginal differences in heating performance or durability, as seen with the clouding issue on some pyramid glass tubes.

Are there any specific maintenance steps to prolong the life of a low-cost gas heater?

Yes. Regular maintenance is key for low-cost units:

1. Always use a cover when the unit is not in use, especially in winter.
2. Clean the reflector and heat elements regularly to maximize radiant efficiency.
3. If using a ‘Buddy’ style heater with large tanks, experienced users advise adding an inline fuel filter to prevent oil residue from clogging the lines, a common problem that requires servicing.
4. Check the regulator and hose connections annually for leaks or signs of wear.

Conclusion: Our Final Recommendation

Choosing the best budget gas patio heater requires a frank assessment of needs versus cost. If you require maximum area heating for frequent social events, a 13KW tower (like the REALGLOW or BU-KO models) is necessary, but be prepared for higher running costs and frustrating assembly.

However, for the vast majority of UK buyers seeking dependable, safe, and genuinely budget-friendly heat that can serve multiple purposes—from camping to emergency garage warmth—we stand by our top selection: the Mr. Heater Little Buddy Propane Heater.

Its unparalleled safety features, especially the ODS and automatic tip-over system, ensure peace of mind, making it suitable for small, enclosed areas where standard patio heaters are inappropriate. While its 1.1 kW output is modest, its radiant performance is instantly effective for personal use, making it the smartest, safest, and most versatile low-cost option available in the current market.
