Propane or butane for a caravan in Ireland?

Choosing gas for a caravan in Ireland comes down to two questions: will it perform in the weather you expect, and is it compatible with your caravan’s gas system?

For colder trips or year-round touring, propane is generally the more practical choice, provided your caravan’s installation and appliances are approved for it. Butane can suit milder-weather use where the system is designed for it. Neither should be treated as a straight swap without checking the equipment.

Why cold weather matters

The liquid gas inside a cylinder must turn into vapour before your appliances can use it. Butane becomes less effective as temperatures approach freezing, so a cylinder can still contain gas but struggle to supply an appliance on a cold morning.

Propane continues to vaporise at much lower temperatures and is generally better suited to winter touring. This does not guarantee a particular heating output in every condition: cylinder temperature, gas demand, remaining contents and the installation all affect performance. Treat published temperature figures as general guidance, not a promise that every appliance will operate down to a fixed outdoor temperature.

For Irish trips that might include chilly nights, early starts or off-season touring, propane is usually the sensible starting point. If you only travel in mild conditions, butane may remain a suitable option for a compatible setup. Read more on our Propane and Butane pages.

Can a caravan use either propane or butane?

Some caravan installations can use either, but that does not mean every bottle, regulator or appliance is interchangeable. Check the caravan handbook, each appliance’s instructions and the labels on the regulator before changing gas type.

Many modern caravans have a fixed, bulkhead-mounted 30mbar regulator designed for both gases. The cylinder connection and suitable high-pressure hose, often called a pigtail, can still differ. Older installations may use a cylinder-mounted regulator specific to the gas and operating pressure.

Do not choose a regulator simply because it fits the bottle. The gas type, cylinder valve, regulator outlet pressure, hose and appliance requirements must all match the approved installation. Do not adjust a regulator or improvise adapters to make an incompatible connection work. Have any necessary installation changes checked by a suitably qualified caravan LPG technician.

Which Rooney’s Gas cylinders should you consider?

Our catalogue includes the following options to discuss when checking your caravan’s requirements:

• Calor 6Kg Propane: a propane option listed for campervan and boat cooking and water heating. Confirm its connection and dimensions suit your caravan.
• Calor 5Kg Butane: a butane option to consider for a compatible system and milder-weather trips. Ask us to confirm the cylinder specifications before ordering.
• Calor 11.34Kg Butane: another butane option, but do not assume a larger cylinder will fit your locker or suit your caravan’s permitted load.

These are catalogue options, not a compatibility guarantee for your particular caravan. Check the cylinder’s height and diameter, the gas locker’s capacity and securing arrangement, and your caravan’s payload allowance. Allow for the weight of both the cylinder and its contents.

Browse our Camping Gas collection, Propane Cylinders and Butane collection to compare the available options.

Before ordering or switching gas

• Confirm the permitted gas type and supply pressure in your caravan and appliance instructions.
• Check the exact cylinder valve, regulator and hose requirements with a competent person.
• Confirm that the cylinder fits, can be secured correctly and stays within the caravan’s weight limits.
• Check whether you need an exchange refill or a cylinder as well as gas. Ask us about exchange eligibility if unsure.

Never try to improve cold-weather performance by heating a cylinder or bringing it into the caravan’s living area. Follow the caravan and cylinder supplier’s safety instructions and keep the gas locker ventilation unobstructed.

Our practical recommendation

For year-round caravan use in Ireland, start by checking whether your approved setup can use propane. For mild-weather trips, butane can be a reasonable choice if your equipment is compatible. The right connection and operating pressure matter just as much as the gas itself.

Unsure which bottle you need? Contact Rooney’s Gas before ordering. Have your caravan model, appliance instructions and details or clear photographs of the existing cylinder connection and regulator ready. We can help you identify the cylinder options and advise when you need a qualified technician to check the installation.
