Paraffin heater buying guide

Updated: 21 October 2026

You are on amazon.co.uk looking at paraffin heaters and kerosene heaters that sit in one list, from a £18.95 greenhouse lamp to a £189 cabinet, and the bullets do not say which job each row is for. This paraffin heater buying guide sorts that list into three purchases, then the fuel grade on the can, then the figures you can treat as claims. The [paraffin heater comparison](/hub/portable-heaters/paraffin-heater) holds the six-row table. Peter F. read those amazon.co.uk listings and public UK sources on 19 October 2026. He did not test the heaters in a lab. A qualifying purchase through our links can earn a commission at no extra cost to you.

Three heaters, not one

A greenhouse wick heater is a tank, a chimney, and a deflector. In this set that is the Trendi E-SP100 at £18.95, with a 4.5 litre tank, a claim of up to 80 hours, and no thermostat. That job is on the paraffin heater for a greenhouse page. A camping stove-heater adds a pan top. DSYOGX is £34.98, Xigner £57.99, PFCTART £89.99, and MENDUNER £133.49. Indoor or Bedroom on those pages is seller text. A PFCTART review found no visible tip-over device. The limits are on the paraffin heater indoor safety page. The Corona RX 2485 listing is £189.00 and the same page also says corded electric. Which name fits which job is on the best paraffin heater page.

Fuel the manual names

GOV.UK treats paraffin and kerosene as names for the same distillate. The can is still a grade. NWF Fuels says BS 2869 Class C1 is for wick heaters and Class C2 is for boilers. Barrettine’s premium paraffin is labelled Class C1, with a minimum flash point of 43 °C, and the maker says it is not recommended in occupied living areas. Rye Oil says Class C2 kerosene in a paraffin heater smokes and, in an enclosed space, can be fatal. That is a merchant’s warning. Petrol is outside both classes, and the Oil Heaters (Safety) Regulations 1977 require a warning against it. No kept listing states a BS 3300 report, so not stated is not a pass. A PFCTART title that also says bioethanol is a clash: a UK review says the instructions do not.

What the numbers on the listing are allowed to mean

Run time and coverage on these pages are claims. The Trendi says up to 80 hours and a 6x8 greenhouse, while the coverage field says 0.0307 m² and the heat field says 4500 W. Two Wests describe their own 4.5 litre heater at about 300 W. That figure is theirs, and it shows why 4500 W on a similar tank is not a night you can plan. The Xigner prints both 9000 BTU/h and 23500 BTU. The PFCTART claims 5 litres and no run time. A UK Corona review’s about 16 hours is one buyer’s turned-down fill, next to a line that says corded electric. If both BTU lines are on the page, you do not yet have a heat figure.

When this category is the wrong buy

If the greenhouse already has a proper mains supply and you want a thermostat, the Royal Horticultural Society points to an electric fan or tube heater. A wick lamp cannot hold a set temperature, and the vent you must leave open throws heat out. Paying £18.95 does not change that. A bedroom overnight is the wrong buy even when the form says Indoor. Carbon monoxide has no smell, and Barrettine does not recommend its C1 paraffin in occupied living areas. A tent is the wrong buy for the camping stove-heaters: the NHS says not to use a camping stove indoors or in a tent.

Common questions

Is paraffin the same thing as kerosene?
GOV.UK treats paraffin and kerosene as names for the same distillate, which is why one amazon.co.uk title can use both. The can is still a grade. NWF Fuels puts BS 2869 Class C1 on wick heaters and Class C2 on boilers. Barrettine’s C1 paraffin is not recommended in occupied living areas. Petrol is neither grade.
Do I buy C1 or C2?
Buy Class C1 when the manual says premium paraffin or the heater is a wick lamp or a cabinet wick heater. Class C2 is the boiler grade. Rye Oil says C2 kerosene in a paraffin heater smokes and, in an enclosed space, can be fatal. That is a merchant’s warning, not a lab result. A Trendi bullet that says premium paraffin is pointing at C1, not at 28-second heating oil.
Is a greenhouse twin-wick heater the same as a Corona cabinet?
No. The Trendi E-SP100 at £18.95 is a 1.95 kg greenhouse lamp with a 4.5 litre tank and no thermostat. The Corona RX 2485 listing at £189.00 is a 7 kg cabinet with 2400 W and 90 m³ printed, and that page also says corded electric. UK reviews of the cabinet describe a removable 4 litre tank. You are choosing a frost tool or a room heater, not two sizes of one product.
Why does one listing say 4500 W and another say 2400 W?
The Trendi heat field says 4500 W, the coverage field says 0.0307 m², and the bullets say a 6x8 greenhouse. Those lines disagree. Two Wests describe their own 4.5 litre heater at about 300 W, which is their figure, not a test of the Trendi. The Corona listing prints 2400 W and also says corded electric. Use a watt line only when the rest of the page does not contradict it.
Can a camping stove go in a bedroom because the form says indoor?
The indoor line is seller text. PFCTART, Xigner, DSYOGX, and MENDUNER all carry it, and several also say camping or outdoor. The NHS says not to use a camping stove indoors or in a tent. A PFCTART review found no visible tip-over device and said indoor use smells like a kerosene lamp. An indoor tag does not mean the 1977 warnings were checked on that ASIN.
