Propane fan heater buying guide
Updated: 16 October 2026
You are in a cold workshop with a barbecue bottle and a 37 mbar regulator, and the listing says 10 or 15 kW. This propane fan heater buying guide checks the data-plate pressure, the fuel and whether the room may hold a flame. The four listings on the [gas heater fan comparison](/hub/portable-heaters/gas-heater-fan) cost about £69.90 to about £135.15. The Products Compared editorial team read the UK listings on 16 October 2026. We did not run a lab test. If you buy through our links, we may earn a commission at no extra cost to you. If the plate and the room do not match, stop before the model names matter.

What you are actually buying
A propane fan heater here is a portable direct-fired LPG blower. Gas burns in the open, a small electric fan pushes the hot air, and the combustion products stay in the room. That is not a 4.2 kW cabinet heater on a domestic regulator, and it is not a plug-in electric fan. The propane heater vs electric fan heater page is that second choice.
The kilowatts on the title are the flame. The plug runs only the fan. If the power fails, the blower stops. Do not buy one as blackout heat. SIAL and the 15 kW DAHTEC state 700 mbar. The 30–50 kW DAHTEC states 1,500 mbar. ALINI states no pressure. A barbecue regulator on a 700 mbar plate is the wrong part.
Pressure, hose and cylinder
The hose has to match that plate. None of the four listings prints a hose standard, so you use the set the instructions name, or you do not light it.
ALINI, at about £75.99, states a propane regulator and a 1.5 m hose. The cylinder is not included. SIAL, at about £69.90, lists neither, so the lower price is the body only. The 15 kW DAHTEC, at about £84.15, does not list a hose, and one UK review said the supplied regulator thread would not take the hose. The 30–50 kW DAHTEC, at about £135.15, lists no hose, and one buyer’s adaptors would not fit the bottle. A small cylinder ices when withdrawal outruns vaporisation. Never heat the cylinder. Connection steps are on the how to use a propane fan heater page.
Propane, butane and the fan plug
Propane gives vapour in a cold UK shed. Butane’s pressure falls as the bottle cools. SIAL names propane, butane or liquefied gas. ALINI names propane/LPG. Both DAHTEC fields leave the gas blank. If the plate does not name it, do not guess from the title.
ALINI is the listing that states a 230 V UK three-pin plug. SIAL states 220 V. Both DAHTEC listings say AC and do not state the volts. Reviewers call these blowers noisy, including one pottery studio that was too loud for the 15 kW DAHTEC. If you need to talk for hours, the pressure match is not enough.
Room size claims
The coverage figures do not agree. ALINI says up to 300 m². The DAHTEC pages say 1,615 sq ft and 5,382 sq ft. SIAL states no coverage.
The Güde GGH 10 L manual, for a 10 kW cannon sold for Germany and Austria, asks for at least 25 cm² of vent per kW and a room larger than 100 m³. That is not printed on the SIAL or DAHTEC listings, and it is not a UK approval. One DAHTEC reviewer said their instructions asked for about 100 m², and a double garage of about 65 m² failed. Use the sheet in the box. The 30–50 kW unit also needs 1,500 mbar, not a 700 mbar regulator.
What to check before you pay
Read the plate and the listing together. Match the pressure, prefer propane unless the plate names butane, and check whether the hose is in the box. Only ALINI states a regulator and hose. Two listings never state the volts. Ignore the largest area claim if the manual asks for a room or a vent you do not have.
Stop if the space has petrol vapour, or if people sleep there, and read propane heater ventilation before you treat a title as permission. If those still match, you are choosing a 10 kW body with no hose, a 15 kW unit with the hose stated, a 15 kW unit with more reviews, or a 30–50 kW unit at 1,500 mbar.
Common questions
Is this the same as a 4.2 kW cabinet heater?
No. A cabinet heater is a low-pressure room heater, usually on a 28–37 mbar regulator, without this cannon fan. These blowers are direct-fired, at 700 mbar or 1,500 mbar where that figure is stated. The hose is a different class, and the exhaust stays in the room. A cabinet you already own does not answer the regulator question.
Will my barbecue regulator run it?
Not if the plate says 700 mbar or 1,500 mbar. Flogas and Liquid Gas UK treat 37 mbar as the domestic propane part, and a high-pressure regulator as a different part. ALINI prints no pressure, so you still need the regulator that listing says is in the box. Forcing the barbecue part onto a blower is the wrong fitting.
Propane or butane in a cold shed?
Propane. It holds vapour pressure when a UK shed is cold. Butane drops off as the bottle cools. SIAL names both gases. ALINI names propane. The DAHTEC fields name neither, so do not assume butane is acceptable because a cabinet heater used it in summer.
Does the box include the hose?
Only ALINI states a propane regulator and a 1.5 m hose. SIAL lists neither. The DAHTEC field lists do not either. One 15 kW review said the regulator thread would not take the hose, and one 30–50 kW review could not fit the bottle. No listing includes the cylinder.
Why do the area figures disagree?
They are not the same measure. ALINI says up to 300 m². The DAHTEC pages say 1,615 sq ft and 5,382 sq ft. A Güde-class manual talks in cubic metres and vent area, and one DAHTEC review cited about 100 m² as a minimum. Coverage is not permission to heat that room. Read the sheet in the box.
