The best gas heaters, compared.
Top pick: Bimson Power BP-G15T Best value: Straame foldable 4.2 kW – About £64.99, with 4.1 from 134 reviews, an oxygen depletion sensor named, and a 21 mm regulator included. Updated October 2026.
A portable gas heater on amazon.co.uk is a butane cabinet for a ventilated room, a direct-fired propane blower for a workshop, or a small cartridge heater for outdoors. For a cabinet, look for a stated oxygen depletion sensor, a flame-failure device and a tip-over switch, plus a regulator that fits the local bottle and a manual that matches the room. A higher kilowatt figure is not a better living-room heater. The other at the same price does not name that sensor. Class, sensor and bottle fitting are set out in the [gas heating buying guide](/hub/heating/gas-heating/sub/gas-heating-buying-guide). Stars and prices come from the amazon.co.uk listings. A cabinet is a flueless radiant heater with the cylinder in the case, usually three settings up to 4.2 kW. A blower is a fan and an open flame, here 10 kW or 7–15 kW, on propane or a dual-fuel claim, with a mains plug or an 18 V battery for the fan. A cartridge heater is about 1.3 kW, uses disposable cans, and is sometimes sold as a heater-stove.

Question 1 of 2
Where will it run?
The Bimson Power BP-G15T is a black forced-air heater at £119.99. The listing states 7–15 kW, 23,000–51,000 BTU/hr and up to 300 cubic metres. Spec weight is 6.3 kg. One review says 4.5 kg, so the spec figure is the one used here. A propane hose, a regulator, spark ignition and a 13 A plug are included. The fuel field says propane and the bullets also say butane. Runtime is up to 12 hours on a 13 kg bottle at full output. The highlight claims a 3 year warranty and an adjustable thermostat, without a degree range. Overheat protection is named. An oxygen depletion sensor is not. amazon.co.uk shows 4.7 from 24 reviews. Seventeen texts are mostly garage and workshop heat, with one fan cable that had to be moved clear of the blades. The star ratio would be 94. The score is capped at 84 so a sample of 24 does not sort above the cabinet with 637 reviews.
Pros
Cons
Best for: A garage or workshop the manual allows, where you already have a 13 A socket and a 13 kg bottle.
Less suitable: Off-grid use, a living room, or a tent chosen because the bullet mentions one.
Specifications
Common questions
Does the Bimson need mains power?
Yes. The power source is corded electric, and the bullets say a pre-fitted 13 A UK plug. The fan will not run off the gas bottle alone.
How long does a 13 kg bottle last on the listing?
The bullets say up to 12 hours at maximum output. Reviews that turn it down towards 7 kW describe a longer run. The bottle is not included.
Is there a thermostat?
The item highlight says an adjustable thermostat, and special features include adjustable temperature. A temperature range is not printed. Overheat protection is named. An oxygen depletion sensor is not.
The DAHTEC BGA2003-10 is a propane blower at £219.00, about 3.8 kg, stated at 10 kW and 34,121 BTU. Airflow is up to 320 cubic metres per hour and consumption is 0.73 kg/h. The fan runs from an included 18 V, 5.2 Ah battery, so there is no mains lead for the fan. Piezo ignition, a flame-failure thermocouple, overheat protection, a metal housing and IPX4 are stated. An oxygen depletion sensor and a tip-over switch are not. Use is limited to outdoors or well-ventilated non-domestic areas. Coverage is stated as 100 square metres. The colour field says 10 Kw, which is not a colour. amazon.co.uk shows 4.7 from four reviews, all positive in the saved listing, which is too few to judge faults. The star ratio would be 94. The score is capped at 70. The gas bottle is not included and the bottle size is not given.
Pros
Cons
Best for: Site or greenhouse work where you want a propane blower without trailing a fan lead, and you accept a four-review listing.
Less suitable: A living room, or a buyer who wants a long UK review trail before spending £219.
Specifications
Common questions
Does the fan need a mains lead?
No. An 18 V, 5.2 Ah battery runs the fan, and the bullets say the battery and charger are included. Runtime in hours is not stated. The gas bottle is separate.
Where does the listing say you can use it?
The indoor or outdoor field says Outdoor. The bullets limit use to outdoors or well-ventilated non-domestic areas, including workshops, garages, warehouses, greenhouses and covered outdoor work.
What safety devices are named?
A thermocouple shuts the gas if the flame goes out, and overheat protection is stated. IPX4 is stated. An oxygen depletion sensor and a tip-over switch are not named. Only four UK reviews are on the listing.
The NJ-H2 from NJ The right choice, made by Fontron LTD, is an indoor radiant cabinet at £99.90. It states 4.2 kW, three settings, piezo ignition, ceramic plates and 84 cubic metres of coverage. Size is 32 × 42 × 73 cm and weight is 8 kg. No mains supply is required. A 21 mm clip-on regulator and hose are included for an 8–15 kg butane bottle. The bottle is not. Flame failure, tip-over and low-oxygen shut-off are named. The room-type field includes a bedroom, which you should not read as permission to heat a bedroom. amazon.co.uk shows 4.3 from 637 reviews, the longest trail in this set. One bar heating a room is a common praise. A stiff hose, a thin cabinet, a fiddly regulator and the Northern Ireland fitting are the common complaints. It is the top pick here because the named sensors and the review count sit together. It is not a workshop blower.
Pros
Cons
Best for: A ventilated living room or similar space on a Great Britain 21 mm butane bottle, if you want the fullest review trail in this set.
Less suitable: A Northern Ireland yellow-top bottle without an adapter, a bedroom chosen from the room-type field, or a garage that needs a 10–15 kW blower.
Specifications
Common questions
Which safety devices does the NJ-H2 name?
The bullets and special features name a flame-failure device, a tip-over shut-off and an oxygen depletion sensor. Ceramic plates and three settings are also listed.
Does the regulator fit every UK butane bottle?
The listing includes a 21 mm clip-on regulator and hose for an 8–15 kg butane bottle. Reviews from Northern Ireland say that fitting does not match local Flogas bottles and that a larger adapter was needed.
Does the listing allow a bedroom?
The room-type field includes a bedroom. The bullets do not add a bedroom limit. An oxygen depletion sensor on the listing is not a bedroom clearance.
This Straame cabinet is £64.99 and 10.2 kg, with low, medium and high stated at 1.5 kW, 2.8 kW and 4.2 kW. Open size on the spec table is 47 × 42 × 74 cm. It names an oxygen depletion sensor, a flame-failure device and an anti-tilt switch, and it includes a 21 mm clip-on regulator and hose for a 13 kg or 15 kg butane cylinder. The cylinder is extra. The room-type field says kitchen, while the bullets name living rooms, conservatories, garages and workshops. Warranty is printed as N/a. amazon.co.uk shows 4.1 from 134 reviews. Heat on one bar is a common praise. The fold claim, poor instructions, a stiff hose and thin metal with a full bottle are the common complaints. It is the best-value cabinet in this set because the same £64.99 Straame does not name an oxygen depletion sensor.
Pros
Cons
Best for: A ventilated room on a 13 kg or 15 kg butane cylinder if you want the named sensors and the 21 mm regulator at £64.99.
Less suitable: Northern Ireland yellow-top bottles, a workshop blower job, or anyone who wants a cabinet that is already built.
Specifications
Common questions
Which safety devices does this Straame name?
The bullets name an oxygen depletion sensor with automatic shut-off, a flame-failure device, an anti-tilt switch, a front mesh guard and an internal bottle retainer.
Is the regulator a Great Britain clip-on?
The listing says a 21 mm clip-on regulator and a gas hose are included, for 13 kg or 15 kg cylinders. The cylinder is not included. A 35 mm Northern Ireland fitting is not mentioned.
Does foldable mean it packs away without tools?
The bullets give a folded size of 42 × 69.5 × 15 cm and four castors. Reviews say you screw it together, and that folding it away again means taking that assembly apart.
The Taylor & Brown 31263 is a green 1300 W heater-stove at £29.99, about 20 × 28 × 27 cm, sold with four butane canisters. Auto ignition, a safety grill, a carry handle and adjustable temperature control are on the listing. The spec field says Outdoor. A bullet also says you can use it indoors with ventilation, or outdoors, and recommended uses include a tent, a caravan and home backup. Weight and a named shut-off device are missing. amazon.co.uk shows 4.1 from 66 reviews. In 26 texts, buyers like the compact cooker-heater and the included cans. Repeated complaints are a failed ignitor, a canister that runs out in roughly an hour to four hours, a door that will not stay shut, and a locking handle that sticks on. One buyer reported flames across the unit on first lighting.
Pros
Cons
Best for: A camping or caravan trip where you want canisters in the box and you will keep the unit outside.
Less suitable: Overnight indoor heat, or anyone who needs a named atmosphere sensor on the listing.
Specifications
Common questions
Does this Taylor & Brown set include gas?
Yes. The title and bullets include four butane canisters. A propane cylinder is described as optional and is not included.
Can you use it in a tent?
The listing asks that question and does not answer it. Recommended uses include a tent. The indoor or outdoor field says Outdoor, while one bullet also claims ventilated indoor use.
Does the listing name an automatic shut-off?
The page asks about an automatic shut-off. The spec table names a grill, auto ignition and temperature control, not an oxygen depletion sensor, flame-failure device or tip-over switch.
The Fishlor mini heater is a blue 420 g unit at £37.18, about 14 × 15 × 15 cm, with a foldable base and a protective net. Coverage is stated as 200 square feet. The heat-output field says 13,000 watts, which is the figure on the listing and is not repeated as 1.3 kW in the bullets. Fuel type says natural gas. One bullet says stainless steel and another says ultra-thin iron. The spec field says Outdoor and tent use. The title also says indoor. Ignition type, a regulator and an atmosphere sensor are not named. amazon.co.uk shows 4.0 from 32 reviews. Eight texts mention a warm bivvy or greenhouse, a flame that died on a full canister, and failure in freezing weather.
Pros
Cons
Best for: A short outdoor job, such as a greenhouse while you are there, if you accept the unclear fuel line.
Less suitable: Indoor heating, a tent overnight, or anyone who needs a named sensor and a clear cartridge size.
Specifications
Common questions
What fuel does the Fishlor listing name?
The fuel-type field says natural gas. The bullets do not name butane, propane or a cartridge size. One review talks about a bottle lasting about eight hours.
Is a storage bag included?
The listing asks and the spec table does not answer. One review says a carry bag was supplied.
Does the listing say it works in all weather?
That question is on the page and is not answered. One review says it does not work in freezing conditions. The indoor or outdoor field says Outdoor, while the title also says indoor.
The DAHTEC BGA1401-15-18 is a yellow forced-air heater at £84.15, 5.07 kg, about 38 × 18 × 30.5 cm. The listing states 15 kW, 51,180 BTU/hr, 20,485 cubic feet per hour and 1.09 kg/h at 700 mbar. Piezo ignition and an overheat cut-off are named. An oxygen depletion sensor, a flame-failure device and a tip-over switch are not. The spec table does not name butane or propane, and it does not list a hose. A review says a hose and regulator fit a capped rear port. The indoor field includes a garage. One verified review says the manual withdrew that domestic garage claim. amazon.co.uk shows 4.0 from 27 reviews. Heat and easy piezo starts are praised. Missing temperature control, fan noise and a faulty regulator thread appear in the texts. The special-features line says manual thermostat, and reviewers say there is no useful heat control.
Pros
Cons
Best for: A well-ventilated non-habitable space if the manual you receive allows that space.
Less suitable: A living room, or a domestic garage you choose because the listing recommends one.
Specifications
Common questions
Is this DAHTEC a living-room cabinet?
No. It is a pedestal forced-air heater stated at 15 kW and 51,180 BTU/hr, with a mains fan. The indoor field and the garage recommendation sit on a different class from a 4.2 kW butane cabinet.
Does the listing name the gas?
The spec table says gas, 1.09 kg/h and 700 mbar. It does not say butane or propane. A bottle size is not given.
Can you trust the garage line?
The listing recommends a garage and says indoor. One verified UK review says the manual on arrival did not support a domestic UK garage. Overheat cut-off is named. An oxygen depletion sensor is not.
This Straame cabinet is £64.99, black, 8 kg, with 4.2 kW and three settings stated. The spec size is 43 × 36 × 74 cm. The bullets also give an open size of about 42 × 74 × 47 cm and a folded size of about 42 × 69.5 × 15 cm. Shut-off for overheat and tip-over is named. An oxygen depletion sensor is not, which matters if you are comparing it with the other Straame at the same price. The cylinder, the regulator and the ignition type are not in the spec table. amazon.co.uk shows 3.9 from 286 reviews. In the first 50 texts, heat output is praised once the cabinet is built. Assembly, thin metal, a stiff hose, awkward lighting and missing nuts or a back panel come up often. It is the same shelf price as the foldable Straame that does name an oxygen depletion sensor.
Pros
Cons
Best for: A ventilated room where you accept a flat-pack cabinet and you will check the manual for sensors the listing omits.
Less suitable: Anyone who wants a named oxygen depletion sensor and a 21 mm regulator printed on the listing. The other Straame at £64.99 states those.
Specifications
Common questions
Does this Straame cabinet name an oxygen depletion sensor?
No. The bullets name an automatic shut-off if it overheats or is tipped. An oxygen depletion sensor and a flame-failure device are not on this listing.
Is a regulator in the spec table?
Included components say heater. A regulator fitting and a bottle size are not in the spec table. Reviews describe a hose that is hard to push on, so some boxes contain a hose, but the listing does not specify the fitting.
Can it be used in a caravan?
The listing asks and does not answer. One review mentions a caravan awning. The bullets name living rooms, garages and offices.
The Lizzie Jacobs Pgh-1.3kw is a 1.5 kg black ceramic heater-stove at £36.00, about 15 × 15 × 22 cm, with piezo ignition. The title includes eight cans, and a bullet specifies 227 g butane cartridges. Coverage is stated up to 40 square metres. The listing claims indoor and outdoor use, and the room-type field includes a bedroom, a living room and an office. Guard, leakage protection and overpressure protection are named. An oxygen depletion sensor is not. amazon.co.uk shows 3.8 from 24 reviews. In 11 texts the repeated point is that the manual says outdoor use only, and one buyer says it is not for cooking, against the stove claim. Treat the manual as the limit, not the bedroom line on the listing.
Pros
Cons
Best for: Outdoor use if you have checked the manual and you want canisters in the same order.
Less suitable: A bedroom or office heated from the listing text, or cooking if the manual forbids it.
Specifications
Common questions
Does the Lizzie Jacobs listing allow indoor use?
The spec field says Indoor, Outdoor, and the room-type field includes a bedroom. Several UK reviews say the manual cover reads for outdoor use only, and one says it is not for cooking.
How many gas cans does the title include?
The title says heater plus 8 cans. A bullet says 227 g butane cartridges and mentions 4-can or 8-can bundles. One review says a small can lasts under two hours.
What safety devices are named?
The bullets name a ceramic burner guard, gas leakage protection, overpressure protection and a correct-canister mechanism. An oxygen depletion sensor and a tip-over switch are not named.
The Livhome 31132 is a black portable heater-stove at £24.99, about 20 × 28 × 27 cm, with auto ignition and a safety grill. The bullets say 1.3 kW and butane cartridges or a propane cylinder. The spec heat-output line says 1300 kilowatts, and the power-source field also says propane or natural gas, so you cannot treat one watt figure as settled. The indoor or outdoor field says Outdoor, and the indoor question on the page is unanswered. Weight, an oxygen depletion sensor, a flame-failure device and a tip-over switch are not named. amazon.co.uk shows 3.7 from 10 reviews, with seven texts: camping heat, a slow kettle, a poor translation of the instructions, and a locking lever that failed on two returned units. Canisters are not in this title.
Pros
Cons
Best for: Outdoor camping where you want the cheapest heater-stove in this set and you will buy the cartridges yourself.
Less suitable: A living room, a tent you plan to heat from the title alone, or anyone who needs a single agreed watt figure.
Specifications
Common questions
Does the Livhome listing say you can use it indoors?
The indoor or outdoor field says Outdoor. The page asks whether it can be used indoors and does not answer that question in the spec table.
What heat output does the listing print?
The bullets say 1.3 kW. The heat-output field says 1300 kilowatts. Those two lines are both on the listing and they do not match.
Are gas canisters in the box?
The title is a camping heater, not a canister bundle. A carry case is asked on the page and is not listed in the spec table.
Ten amazon.co.uk listings are kept. The score starts from the star ratio: stars divided by five, times 100, so 4.3 becomes 86. A thin sample is capped so it does not sort above a cabinet with hundreds of reviews. Review text, a missing oxygen depletion sensor, and a manual that clashes with the title decide the awards. They are not folded into the base ratio. There is no laboratory heat test, no BS EN 449 certificate check, and no Gas Safe inspection. Weights sum to 100.
Amazon star line
40%The base score is the amazon.co.uk star ratio for that ASIN. 4.3 from 637 becomes 86. 4.1 becomes 82. The figure is the listing average, not a lab test.
Review sample
25%A small sample is capped. The Bimson star line is 4.7 from 24 and the score is capped at 84. The DAHTEC 10 kW line is 4.7 from 4 and the score is capped at 70. Four texts cannot set the order.
Named safety devices
20%The top pick needs an oxygen depletion sensor, a flame-failure device and a tip-over switch named on the listing, plus at least 50 reviews. The NJ-H2 meets that. A cabinet that omits the sensor does not take the award.
Price against the sensor
15%Best value is a different ASIN: the lowest price that still scores at least 50, has more than 100 reviews, and names an oxygen depletion sensor. Both Straame cabinets are £64.99. Only the foldable one names the sensor.
A portable gas heater is a butane cabinet, a direct-fired blower, or a cartridge heater. The decision is which of those three the manual actually allows in your space. A higher kilowatt figure does not make a blower into a living-room fire. Read the named safety devices, the regulator fitting, and the manual against the title before you compare shelf prices. Stars below are amazon.co.uk listing averages. This is not a lab test.
A portable gas heater in this comparison is one of three machines. A cabinet is a flueless radiant heater with the cylinder in the case, usually three settings up to 4.2 kW. A blower is a fan and an open flame, here 10 kW or 7–15 kW, on propane or a dual-fuel claim, with a mains plug or an 18 V battery for the fan. A cartridge heater is about 1.3 kW, uses disposable cans, and is sometimes sold as a heater-stove. Listing titles often mix those jobs.
Several cartridge listings say indoor in the title and outdoor-only on the product or in the manual. One 15 kW review says the manual withdrew a domestic garage claim. Believe the manual you receive.
A 21 mm clip-on suits blue butane cylinders in England, Scotland and Wales. Yellow butane cylinders in Northern Ireland use a 35 mm jumbo fitting. Reviews on the NJ-H2 say the included clip-on does not match local Flogas bottles.
A blower is an open flame with a fan. Combustion products enter the room. A home or garage line on the listing is not clearance for a habitable room. Use it only where the manual allows, and switch it off when you leave.
Liquid Gas UK says indoor cabinet heaters use butane cylinders only, and that propane cylinders stay outdoors. A 10–15 kW blower is not a living-room fire. The cabinets here state up to 4.2 kW. The blowers state 10 kW, 15 kW, or 7–15 kW. Two spec lines disagree with the 1.3 kW cartridge class: Fishlor prints 13,000 W, and Livhome prints 1,300 kilowatts beside a 1.3 kW bullet. The regulator has to match the bottle.
HSE expects an atmosphere-sensing device on a cabinet heater, plus ventilation. Flame failure and tip-over are separate. An oxygen depletion sensor does not replace an open vent, and it does not make a heater suitable for a bedroom, a tent or an unventilated room. The NJ-H2 names flame failure, tip-over and an oxygen depletion sensor. The Straame foldable names an oxygen depletion sensor, flame failure and an anti-tilt switch.
Three typical situations, each with a recommendation from this comparison.
You want a few supervised hours of radiant heat in a ventilated living room, with a butane bottle you can exchange locally. The NJ-H2 is the top pick if a 21 mm regulator matches that bottle. Do not choose it from a bedroom line on the room-type field.
You need a blower in a space the manual allows, then switched off. The Bimson Power BP-G15T is the blower with the higher adjusted score, a 13 A plug, and a hose and regulator on the listing. It is not a living-room cabinet.
You want a cartridge heater outside the tent, and you will ignore an indoor bullet the manual contradicts. The Taylor & Brown 31263 includes four butane canisters. The spec field says outdoor. Keep it outside.
The top pick is the NJ-H2 at about £99.90. It has the highest adjusted score among listings with at least 50 reviews, 4.3 from 637, and the listing names an oxygen depletion sensor, flame failure and tip-over, with a 21 mm regulator and hose. Best value is the Straame foldable cabinet at about £64.99, which names the same sensor and has 4.1 from 134 reviews. Skip the NJ-H2 for a Northern Ireland yellow-top bottle, or for a bedroom chosen from the room-type field. Skip the Straame foldable if you want a cabinet that arrives already built.
Straame foldable 4.2 kW
About £64.99, with 4.1 from 134 reviews, an oxygen depletion sensor named, and a 21 mm regulator included.
