What is the difference between propane and butane?
Butane and propane are both popular fuels for powering gas appliances, but they differ mainly in their freezing and boiling points.
- Propane: Freezes at -180°C and burns at -42°C—ideal for colder outdoor environments.
- Butane: Freezes at -140°C and has a higher boiling point of -2°C, making it particularly well-suited for indoor use.
What is butane used for?
Butane is an incredibly versatile fuel that goes far beyond just heating your home. While its primary role is to provide efficient indoor heating, here are some of the many popular butane gas uses:
Butane for heating:
Perfect for warming your home during chilly evenings, butane is a reliable choice for indoor heating appliances. Using a butane gas cylinder with a quality heater ensures consistent, efficient warmth that can help keep energy costs low.
Butane for cooking:
Many portable stoves and kitchen appliances run efficiently on butane. It burns cleanly and provides a steady flame, making it ideal for everything from indoor cooking to preparing meals while camping.
Butane for outdoor heaters:
Whether you're enjoying your patio or garden, butane can power outdoor heaters that create a cosy ambience. Just remember to use these devices safely—ensure proper ventilation and place them away from flammable materials.
Butane for BBQs:
For those who love grilling, butane is a popular alternative to propane. When deciding between the two, consider your appliance’s design and local fuel availability. Both fuels have their merits, but butane’s convenience makes it an attractive option for many outdoor enthusiasts.
Butane for camping:
Lightweight and portable, butane is a top choice for camping. It powers not only cooking stoves but also compact heaters, providing both warmth and a means to cook meals on the go.
Finding the right butane cylinder size
Selecting the appropriate cylinder size is key to meeting your heating needs.
Butane contains 13.7 kilowatt-hours (kWh) per kilogram, so our 11.34kg butane gas cylinder provides approximately 155kWh of energy.
To put this into context, consider a typical 3-bar cabinet heater with different settings:
- Low (1 bar) – 1.4kW: An 11.34kg cylinder lasts approximately 111 hours (155kWh / 1.4kW).
- Medium (2 bars) – 2.8kW: An 11.34kg cylinder lasts approximately 55 hours (155kWh / 2.8kW).
- High (3 bars) – 4.2kW: An 11.34kg cylinder lasts approximately 37 hours (155kWh / 4.2kW).
While the 11.34kg butane gas bottle is a popular choice, Calor also offers a smaller 5kg butane gas bottle option - perfect for indoor mobile heaters.
Safety tips for butane heating
When it comes to using butane for heating, safety should always be the top priority. Follow these butane safety tips to protect you and your home:
- Proper ventilation: Always ensure your heating area is well-ventilated to prevent the buildup of harmful gases.
- Carbon monoxide prevention: Use your butane heater in accordance with the manufacturer’s guidelines to minimise the risk of carbon monoxide poisoning.
- Safe storage & handling: Store your butane gas cylinder in a cool, dry place away from direct sunlight and ignition sources. For more detailed safety guidance, check out our Cylinder Safety Tips.
Evaluating costs: Butane vs. electricity & oil
Butane is a cost-effective alternative to oil heating—especially for homes not connected to the gas grid. Here’s how butane compares with other heating options:
Butane vs. Electricity:
Electric heaters offer great convenience, but they can become expensive when used over long periods, particularly during peak hours. Butane heating, on the other hand, tends to have lower running costs, making it a more economical choice for sustained use.
Butane vs. Oil:
Oil heating usually comes with higher fuel expenses and the need for regular maintenance. In contrast, butane provides efficient, consistent warmth with lower overall costs, giving many households a competitive edge in managing their heating bills.
Choosing the right butane heater
Selecting the perfect butane heater for your home involves more than just picking a model—it’s about matching the heater’s performance to your specific needs. Consider the following when making your choice:
- Size & power output: Choose a heater with the right wattage for the space you want to warm. A heater that’s too small won’t effectively heat your room, while one that’s too large could be inefficient.
- Features & safety: Look for models with features such as automatic shut-off, thermostatic control, and tip-over protection to enhance safety—especially important for butane heaters indoors.
- Portability: If you plan on moving your heater between rooms or taking it on camping trips, opt for a lightweight, easy-to-transport model such as our 5kg butane gas bottle option.
- User reviews & reliability: Reading customer reviews can offer insights into long-term performance and reliability, ensuring you buy a product that meets your expectations.
The takeaway
Butane offers an affordable, efficient, and versatile heating solution for your home—whether you’re using it for indoor warmth, cooking, or even outdoor activities. With the right butane gas cylinder and heater selection, you can enjoy safe and economical heating all year round.
