Armoured LPG 4 Cylinder Upgrade Kit

The Calor armoured LPG 4 cylinder upgrade kit is the part you need to grow a two-cylinder changeover system into a four-cylinder one. More bottles means more gas in reserve and longer between changeovers, useful on sites and properties that get through a fair amount of LPG. It’s designed to pair with the Calor LPG 2 cylinder automatic changeover kit with OPSO, extending that setup rather than replacing it.

The key feature here is the armoured hosing, which adds a protective layer against general wear, sharp objects and vermin. It’s squirrel proof, so it’s the version to choose where cylinders and pipework are kept outside and at risk of being chewed or knocked.

Because it connects into an existing changeover system on the high pressure side, it should be fitted by a competent person following Calor’s own guidance, not improvised. If you’re not certain your current setup is the matching two-cylinder changeover, it’s worth checking before you order.

FAQs

What does this upgrade kit do?

It extends a Calor two-cylinder automatic changeover system to four cylinders, giving more gas in reserve and longer between changeovers. It pairs with the Calor LPG 2 cylinder changeover kit with OPSO. It’s an addition to that system, not a complete system on its own.

What’s “armoured” and “squirrel proof” about?

The hosing has a tough armoured outer layer that protects it from wear, sharp objects and vermin, including squirrels chewing it. It’s the version to choose where cylinders sit outdoors. A non-armoured upgrade kit is also available for sheltered locations.

Will it work with my changeover system?

It’s designed to go with the Calor LPG 2 cylinder automatic changeover kit with OPSO. If your system matches that, this kit extends it to four cylinders. If you’re not sure, call the yard on 0118 9242888 and we’ll help you check before ordering.
