For domestic properties that live off the mains-gas grid or for industrial units who need a bulk gas supply, LPG is becoming an increasingly attractive alternative fuel for heating, cooking or industrial uses. Until recently, oil has always been the preferred option but the market for LPG consumption has been expanding and is expected to continue expanding for the foreseeable future.
Most LPG suppliers take full responsibility for the siting and maintenance of an LPG supply, but there are various options you can consider, depending on the nature of your use and your premises. If you decide to go with LPG, a big part of this is choosing the right storage facility and location.
Do you have enough space?
A major consideration when looking at LPG supply is how much outside space you have, because you will definitely need some, however big or small your requirements are. You need large outdoor spaces whether you require a bulk storage tank or just some 47Kg cylinders, and you will also need good access to the road and possibly access for a delivery tanker to back up to your tank.
Storing LPG can be done in bulk tanks, underground tanks or cylinder packs, and this really depends on how much LPG you need and the property you are supplying. The most common storage facility for LPG is a 1200-litre above-ground tank, which is suitable for most domestic properties and industrial buildings. You will require a minimum space of approximately 8m x 7m and you will also need to prepare a concrete base or plinth for the tank to stand on. In most industrial units this is also guarded by a barrier to prevent damage from passing fork trucks or delivery lorries, but this also adds to the space required. Some LPG suppliers can provide a pre-fabricated base as part of the installation package but this needs to be agreed in initial discussions. The UKLPG code of practice states that there should be a minimum of 3 metres between the tank and any building, boundary line or source of ignition. This is a key consideration when deciding on the storage option, or indeed whether LPG is suitable at all.
While oil tanks must be stored above ground, an LPG tank can be stored below ground. This is sometimes for cosmetic purposes, but also to save space and for practicality. Typically, the only visible sign of the tank will be an access point in the ground, which is the tank lid that can be opened for refuelling.
Smaller storage options
Smaller properties with a lower heating demand or limited outdoor space, may be able to work with LPG cylinders. These are typically 47Kg in capacity and are installed in pairs. There is often an automatic change-over valve which ensures continuous supply by switching from one cylinder to another when one empties.
Cylinders should be stored outside in a robust unit, such as a lockable wire mesh cage, and again should be positioned away from windows, doors and uncovered drains to reduce danger and the potential for damage, albeit only a minimum distance of 1 metre in this case. But be aware that you should not block access or exit routes from the property. Smaller cylinders need to be stored upright and should be chained, ideally to a wall, so that they cannot fall over.
