Butane is not ideal for patio heating — it is better suited to indoor portable heaters and caravanning appliances used in mild conditions. For an outdoor patio heater used through the UK season, propane is the recommended gas: it performs consistently down to around −42°C, whereas butane begins to lose pressure and output below about 5°C — precisely the conditions when a patio heater matters most.
The 21mm refers to the bayonet fitting on the cylinder valve — the most common butane regulator in the UK. If your current regulator clips onto the valve rather than screwing on, and is blue, it is almost certainly a 21mm fitting and will work with this cylinder. If it screws on, or if you are unsure, check the label on your regulator before ordering. Propane cylinders use a different connection.
Yes — butane is suitable for use with compatible indoor portable gas heaters. The key requirement is ventilation: always run an indoor gas heater in a room with a window slightly open or adequate air circulation. Never use a propane cylinder indoors or an appliance rated for outdoor use only. Check your heater's manual for the approved gas type before connecting a new cylinder.
To start with Eastern Gases you will need a Flogas cylinder. On your first order, a refundable deposit covers the new cylinder. Your existing cylinder stays with your current supplier — return it to them directly to recover your original deposit. Once you have a Flogas cylinder through Eastern Gases, every subsequent delivery is a straight exchange: empty collected, full one left in its place.
