The best gas heater fans, compared.
Top pick: SIAL Q10A 10 kW gas fan heater Best value: ALINI ALINI15GH 15 kW propane fan heater – Best value because the propane regulator and 1.5 m hose are included at about £75.99, with a 230 V UK plug. Updated 16 October 2026.
A gas heater fan is a portable direct-fired blower: propane burns in the airstream, a mains fan pushes the hot air, and the combustion products stay in the room. People buy one for a well-ventilated workshop, site or agricultural space, not for a bedroom, a caravan or a room with petrol vapour. Match the data-plate pressure, often 700 mbar or 1,500 mbar, to the regulator, and use a room the instructions allow. Liquid Gas UK says mobile heaters should not be used where flammable vapours are common, and it names garages, even though titles still say garage. Where the flame is refused is in the [gas heater fan ventilation guide](/hub/portable-heaters/gas-heater-fan/sub/gas-heater-fan-ventilation). Fresh air has to carry away carbon dioxide, water vapour and any carbon monoxide from a poor flame. Fit a BS EN 50291 carbon monoxide alarm. Approved Document J requires that alarm for fixed appliances; fit one here anyway.

Question 1 of 2
What space are you heating?
At £69.90 the SIAL Q10A is the 10 kW blower in this set, and the three UK review texts under a 4.2 average from seven reviews describe short bursts in a shed or garage rather than a full day of heat. One review says it heated a garage in cold weather and was easy to use. Another calls it light, with only a slight smell. The listing states 700 mbar, 300 cubic metres an hour, piezo ignition, overheat protection and a flame-out cut-off, on a 220 V cord, and the unit weighs 5.46 kg. A hose and regulator are not listed, so that price is the heater on its own. In the same small set, one reviewer reported fumes and a headache in a vented workshop, and others say it is noisy and uses a lot of gas. A 4.2 from seven reviews is a thin file, and the workshop line on the page is not a reason to run it where people sit.
Pros
Cons
Best for: A short burst of 10 kW heat in a well-ventilated non-habitable space, if you already own a 700 mbar hose and regulator.
Less suitable: A lived-in room, a buyer who needs the hose in the box, or anyone treating seven reviews as a long-term record.
Specifications
Common questions
What safety cut-off does the listing state?
Overheat protection and flame-out protection. The bullets say the gas shuts off if the heater gets too hot or if the power fails.
Which fuels and what pressure are listed?
Butane, liquefied gas and propane, at 700 mbar. Voltage is 220 V. A hose and regulator are not listed.
Where does the listing say it can be used?
Recommended uses include workshops, agricultural heating and portable heating. Room type says outdoor areas and well-ventilated rooms. One review reported fumes and a headache in a vented workshop.
The DAHTEC BGA1401-50T-18 is the 30–50 kW blower at £135.15, and four UK review texts under a 4.1 average from six reviews call it very powerful, with the heat adjustment praised in one of them. The listing states 1,500 mbar, piezo ignition, an airflow claim of 35,315 cubic feet an hour and an overheat cut-off, in a 9.5 kg body measuring 66.5 × 25 × 41 cm. Fuel name, volts and burn rate are not stated, and neither is a hose or regulator. One buyer bought adaptors that still would not fit the gas bottle, so the heater never went into service. Another says that at 50 kW it uses a lot of gas and needs a big bottle. With only six reviews, the 4.1 average cannot show how often that fitting problem repeats. This is a large-space cannon only if you already know the 1,500 mbar connection, and it is a poor buy for a single garage the 15 kW units are sized around.
Pros
Cons
Best for: A large ventilated site or agricultural space that already has a 1,500 mbar supply and a big propane cylinder.
Less suitable: A single garage, a first cylinder, or a buyer who expects the bottle fitting in the box.
Specifications
Common questions
What output does the listing state?
30–50 kW, also written as 102,000–170,000 BTU/h. Working pressure is 1,500 mbar. The airflow claim is 35,315 ft³/h.
Is a regulator included?
The listing does not list a hose or regulator. One review said bought adaptors would not fit the gas bottle.
Does it state a safety shut-off?
Yes. The bullets say the gas cuts off if the temperature rises too far. Special features include overheat protection.
Across 27 amazon.co.uk reviews, the DAHTEC BGA1401-15-18 sits at 4.0 and £84.15, and 19 of the stored UK texts describe fast heat in a workshop, shed or garage, including one double garage that felt warm in about 10 minutes. The listing states 15 kW, or 51,180 BTU/h, 700 mbar, a burn rate of 1.09 kg/h and an overheat cut-off that stops the gas if the temperature rises too far. Piezo ignition is praised as simple, and several reviewers call the 5.07 kg body sturdy. The same reviews dispute the adjustable-flame and manual-thermostat lines: more than one says there is no heat control in use. A supplied regulator thread would not take the hose for one buyer, who returned the unit, and another says the instructions demanded a room of about 100 square metres while their double garage was about 65. It is also described as loud, including too loud for a pottery studio. The larger review file is the reason it is the top pick here, if you can live with a single output and you check the thread before you fill a cylinder.
Pros
Cons
Best for: A ventilated non-habitable space around 15 kW when you want the longest UK review file in this set and you will check the hose thread.
Less suitable: A room under the size in the instructions, or a buyer who needs a real thermostat and a named UK plug voltage.

Common questions
Does the listing state a safety shut-off?
Yes. The bullets say the gas supply cuts off if the temperature rises too far. Special features include overheat protection.
What gas and voltage are stated?
The technical fields do not name the gas or the volts. Working pressure is 700 mbar and the item highlight states 1.09 kg/h. Power source is AC.
Can the heat be turned down?
The bullets say adjustable flame settings and special features say a manual thermostat. Several UK reviews say there is no heat control.
The ALINI ALINI15GH is listed at £75.99 as a 15 kW propane blower, and six UK review texts under a 4.0 average from 11 reviews mostly praise how fast a small unit heats a garage. The box contents are the practical difference in this set: the listing states a propane regulator and a 1.5 m hose, and a 230 V UK three-pin plug for the fan, at 3.7 kg and one speed. The burn rate is given as 1.09 kg/h. Working pressure and an overheat cut-out are not stated on the listing. Reviewers who wanted a lower flame say the gas flow cannot be regulated, so a 6 kg bottle empties quickly. One unit arrived damaged and was kept because the workshop needed heat that day, and one buyer returned theirs after finding the heat poor next to an 8 kW diesel heater. You get the hose in the price, and you do not get a stated shut-off or a second speed.
Pros
Cons
Best for: A ventilated workshop or site space when the regulator and hose have to be in the box and one output is enough.
Less suitable: Anyone who needs a stated shut-off, a lower flame, or a long review file before they buy.
Specifications
Common questions
Does it come with a regulator?
Yes. The listing states a propane regulator and a 1.5 m hose. The cylinder is not listed as included.
What heat output is stated?
51,000 BTU and a burn rate of 1.09 kg/h. The same bullet pairs an air figure of 320 m³ with warming up to 300 m².
What powers the fan?
A 230 V UK 3-pin plug. The listing does not state an overheat cut-out or a working pressure. One review says the gas flow cannot be regulated.
The editorial scores are the figures on the four amazon.co.uk cards, dated with the 16 October 2026 shelf prices. On each card the score starts from the star average, adds a smaller amount for the review count and for stated fuel, pressure, cut-off, hose or plug, then subtracts for faults in the stored UK reviews. The highest score is the top pick. The best value is the listing that includes the regulator and hose in the price. This is not a laboratory test.
Amazon stars
40%The amazon.co.uk star average is the largest block. On the cards a 4.0 average contributes 40 points, a 4.1 contributes 41 and a 4.2 contributes 42.
Review volume
20%Review count is scored apart from the stars. The cards give 18 points from 27 reviews, 8 from 11, and 4 from six or seven. Six to 27 reviews is still a thin file.
Stated fuel, pressure and cut-off
25%Named fuel, working pressure, a flame-out or overheat cut-off, and a hose or UK plug add points. The cards award 12 where those lines are present and 8 where pressure and an overheat cut-off are named without a fuel or a hose.
Faults in the reviews
15%Faults in the stored UK reviews are taken off. The cards deduct 8 for fumes, no heat control, a hose thread or adaptors that did not fit, and 6 where the gas flow cannot be regulated and a unit arrived damaged.
You are choosing a forced-air direct-fired cannon, not a cabinet heater and not a 13 A electric fan. The four kept listings are for a well-ventilated workshop, site or agricultural space where petrol and solvents stay out of the air. Shelf prices on 16 October 2026 run from about £69.90 to about £135.15. A 37 mbar domestic regulator will not match a 700 mbar or 1,500 mbar plate. Stars between 4.0 and 4.2, from 6 to 27 reviews, are not a durability test.
A gas heater fan is a portable direct-fired LPG blower. Propane burns in the airstream, a mains fan pushes the hot air, and the combustion products stay in the room. There is no flue. Fresh air has to carry away carbon dioxide, water vapour and any carbon monoxide from a poor flame. Fit a BS EN 50291 carbon monoxide alarm. Approved Document J requires that alarm for fixed appliances; fit one here anyway.
Domestic propane regulators at 37 mbar, and the 28–30 mbar regulators on some butane cabinets, are not the working pressure on these plates. The hose and regulator must match the cylinder valve. If a regulator will not seal, stop and call a Gas Safe engineer.
Amazon titles in this set still say garage. Liquid Gas UK says mobile heaters should not be used where flammable vapours are common, and it names garages. Calor takes the same line on petrol vapour. A stated workshop job is not a reason to run the heater where people sit.
The DAHTEC 15 kW bullets say adjustable flame settings and a manual thermostat. Several UK reviews say there is no heat control in use. The ALINI reviews say the gas flow cannot be regulated. Do not buy a lower flame that the stored reviews say is not there.
If petrol, solvents or other flammable vapour can be present, do not use an open flame. Bedrooms, bathrooms, basements, caravans and unattended running are out as well. Direct-fired means no flue: the combustion products stay in the room. Fresh air has to carry away carbon dioxide, water vapour and any carbon monoxide from a poor flame. Fit a BS EN 50291 carbon monoxide alarm. Liquid Gas UK and Calor refuse garages where petrol vapour is common, even when the Amazon title says garage.
700 mbar or 1,500 mbar is not a 37 mbar domestic propane regulator. The hose and regulator must match the cylinder valve. Putting a 37 mbar regulator on a 700 or 1,500 mbar heater is a common mistake. Propane is the fuel for a UK winter. Butane vapourises poorly near 0 °C. The SIAL listing names butane as well as propane and liquefied gas; a cold shed still wants propane. At 15 °C, propane is about 7 bar in the cylinder and butane about 1.5 bar. Do not store propane in a basement.
Three typical situations, each with a recommendation from this comparison.
You can keep petrol and solvents out of the air, open the vents, and accept noise for a short burst around 15 kW. The DAHTEC BGA1401-15-18 has the longest UK review file in this set. Check the hose thread before you fill a cylinder, and do not expect the flame to turn down just because the feature list says so.
You already know you need a high-pressure regulator, and you do not own one. The ALINI ALINI15GH lists a propane regulator and a 1.5 m hose at about £75.99, with a 230 V UK three-pin plug and one speed. Working pressure and an overheat cut-out are not stated.
The space is ventilated, non-habitable and larger than a single garage, and a 1,500 mbar supply and a big propane cylinder are already there. The DAHTEC BGA1401-50T-18 states 30–50 kW. The listing does not include a hose or regulator, and one buyer’s adaptors did not fit the bottle.
The DAHTEC BGA1401-15-18 at about £84.15 is the top pick: the highest editorial score in this set, 58 out of 100, on 4.0 from 27 amazon.co.uk reviews, with 15 kW, 700 mbar, 1.09 kg/h and a stated overheat cut-off. Several of those reviews say there is no heat control in use, and one regulator thread would not take the hose. The ALINI ALINI15GH at about £75.99 is the best value because the propane regulator and 1.5 m hose are in the price, on a 230 V UK plug, at one speed. The SIAL Q10A is the about £69.90 10 kW unit if you already own a 700 mbar hose. The 30–50 kW DAHTEC is only for a large ventilated space that already has a 1,500 mbar supply.
