Bottle Gas Specialist For Over 20 Years

CO2 (Carbon Dioxide) Bottles

CO₂ (Carbon Dioxide) Bottles are one of the most versatile gases we supply. On this page you can shop online for rent-free CO₂ cylinders in a variety of sizes for:

  • Home bars, kegerators and soda systems
  • Planted aquariums and hydroponics
  • Hospitality, catering and frozen drinks machines
  • Events, stage effects, confetti cannons and paintball

Choose a cylinder from this main range, or use our dedicated subcategories to go straight to the CO₂ bottle that matches your specific use case.

Adams Gas supplies CO2 bottles for domestic, trade and industrial use, with options ranging from compact home carbonation refills to larger cylinders for beverage dispense, hydroponics and specialist applications. Every cylinder in this category is rent-free, so you can buy or replace your gas without ongoing hire charges or long contracts.

If you need a CO2 bottle for drinks, an aquarium, paintball, stage effects or day-to-day trade use, this range is built to cover practical demand rather than a single niche. With over 35 CO2 products, UK-filled stock and a nationwide supply network, Adams Gas is set up for one-off buyers and regular users alike.

Refill and Exchange, Not Just Exchange

Many CO2 suppliers only offer exchange. Adams Gas offers both refill and exchange, giving you a more flexible way to keep your cylinder in service. If you want to refill your CO2 cylinder rather than simply swap it, that option is available across this category.

This matters for customers who want a straightforward, rent-free supply route with no hire charges. It also makes local collection simpler, because many customers can arrange refill or exchange through the nationwide stockist network instead of being tied to one collection point.

Cylinder Sizes Available

This category includes disposable and refillable CO2 options, so you can match the bottle to the job rather than overbuying. Smaller formats suit home carbonation and portable use, while the larger refillable cylinders are designed for regular leisure, hospitality and industrial demand.

Disposable and Small Format

Size Typical use Notes
420g / 425g Home carbonation systems and sparkling water machines Replacement cylinders for common screw-on and push-on home carbonation setups, including blue and pink systems
580g Portable beverage and food use 0.95 litre food grade disposable CO2, E290

Refillable Cylinders

Size Best suited to Why customers choose it
1.5kg Compact aquarium, home bar and light leisure use A practical entry size when you want a refillable bottle without taking up much space
3kg / 3.15kg Aquariums, home bars, regular leisure use and portable trade setups A good middle ground for customers who need more run time than a compact bottle
6.35kg Beverage dispense, paintball, hospitality and growing systems A strong all-round choice for customers with steady ongoing demand
15kg Busier hospitality, beverage and specialist commercial use Suited to heavier use where fewer bottle changes are helpful
34kg High-volume site use and larger fixed installations The largest option in this category for customers who need extended supply capacity

Common Uses for CO2

Home and Leisure

CO2 is widely used at home for sparkling water, home bars and aquarium plant growth. The 420g and 425g cylinders are aimed at replacement use for common home carbonation machines, while the 1.5kg and 3kg / 3.15kg refillable sizes are often a better fit if you want a reusable cylinder for an aquarium, a home bar or another small setup that runs more regularly.

Paintball is another common use, including customers who need a dependable cylinder filling service as part of their regular routine. Because Adams Gas offers refill and exchange, you have more than one way to keep your bottle ready for the next session.

Trade and Hospitality

For pubs, bars, beverage operators and food businesses, CO2 can be used for drinks dispense, frozen drinks machines and glass frosting. If your main requirement is CO2 for drinks or beverage service, Adams Gas can supply suitable options for that purpose, including food grade disposable stock and larger cylinders used in beverage environments.

Customers running cellar or bar equipment may also want to view the Beer & Cellar Gas range for related dispense products. That gives you a clearer route if your setup goes beyond straight CO2 supply and into broader beer or cellar gas requirements.

Industrial and Specialist

CO2 is also used in hydroponics, aquatic plant growth, stage and theatrical effects, confetti cannons, blasters and airbrush tattoo work. These applications can range from occasional specialist use to frequent site demand, which is why the refillable sizes run from 1.5kg right up to 34kg.

If you are comparing gases for workshop or fabrication environments as well, the welding gas types guide is useful background reading, while the CO2 for hydroponics article covers one of the more common specialist applications in more detail.

Which Size Do I Need?

The right CO2 cylinder size depends on how often you use it, how portable it needs to be and whether you are supplying a simple home setup or a site with regular throughput. As a rule, smaller cylinders are easier to store and move, while larger cylinders reduce how often you need to arrange a refill or exchange.

  • 420g / 425g is the practical choice for replacement use in home carbonation machines where size and fitting type matter more than long run time.
  • 580g suits portable food and beverage use where you specifically need a small food grade disposable cylinder.
  • 1.5kg is a sensible refillable starting point for compact aquariums, home bars and lighter personal use.
  • 3kg / 3.15kg gives you more usable capacity for regular aquarium, leisure and light trade demand without stepping into a much larger bottle.
  • 6.35kg is a common step up for hospitality, paintball, hydroponics and mixed-use setups that need a dependable all-round size.
  • 15kg works well when CO2 use is heavier and downtime from bottle changes becomes inconvenient.
  • 34kg is intended for larger volume applications where maximum capacity is the priority.

If you are unsure, it is usually better to choose based on usage pattern rather than just bottle price. A smaller cylinder may be ideal for occasional home use, but a larger refillable option is often more practical for pubs, beverage setups, hydroponics rooms and other environments where the gas is used consistently.

Nationwide CO2 Supply

Adams Gas has a nationwide stockist network with 92 stockists, making it easier to source CO2 locally whether you need a new bottle, a refill or an exchange. If your question is where to get a CO2 tank filled near you, the first step is to find a stockist and check the most convenient local option.

For customers outside stockist catchment or planning a wider order, you can also review the areas we deliver. That gives you a straightforward picture of local availability while keeping the same rent-free model: no hire charges, no rental contract and flexible refill or exchange support.

FAQs

As a trusted supplier of gas, we frequently get asked questions about gas safety, the difference between butane and propane, as well as the best uses for our gas products. In this blog, we’ll be answering our most common FAQs.

We stock a wide range of butane gas bottles for residential and commercial use. It’s a versatile gas and can be used in fridges, lighters, and aerosols. Butane is also popular for camping and caravanning because it provides portable heating, as well as the capability to fuel barbecues quickly and efficiently.

Unlike gases such as carbon dioxide, methane and nitrous oxide, butane is not a greenhouse gas and does not affect the ozone layer.

If you find yourself in a situation where a gas cylinder is involved in a fire or close to fire, do not approach or attempt to move the cylinder or operate the valve. Evacuate the area immediately and keep others away.

Contact the Fire & Rescue Service as soon as possible, informing them of your location, as well as the type and quantity of gas involved.

As a gas bottle supplier, we know there are several things that influence how long a gas bottle lasts. These factors include, your burner, low or high heat, the use and frequency of use.

The gas application is a major factor of how long your bottle will last because it determines how much gas you need. A 45kg cooking gas bottle can last around 244 days, depending on the burner you have and the frequency with which you use the gas. If you have a Calor gas propane 6kg bottle and if you consider that 1kg of propane can give around 13.6 kWh of energy – you will be able to use a cooker for about 81.6 hours.

At Adams Gas, we provide many different types of gas, including butane. Each 220g of butane will last for approximately 3 to 4 hours on low heat, meaning you can really get your money’s worth with this type of gas. Our Calor gas butane 15kg bottles could last for up to 238 hours on low heat.

Fire up the BBQ whatever the weather with our range of Calor bottled gases. Not only can you start cooking almost instantly after turning your gas on, you can also carry on cooking for longer.

Propane gas exerts significantly more pressure than butane at the same temperature, meaning it’s ideal for exterior storage and BBQ use all year round.

Butane gas is also great for barbeques as it produces around 12% more energy than propane when the same volume of each gas is burned. While butane is a popular choice for those who light up their BBQ a few times a week, you should consider that butane gas won’t flow when the weather is cold.

With energy, the standing charge is the cost of having a gas and electricity supply, then you pay usage charges on top. The standing charge is the fee you pay to your energy supplier simply because it gives you access to energy.

Transporting gas cylinders in a safe and responsible manner is essential to the safety and welfare of your employees and the general public.
