Flogas NI What Type Of Gas Supply Do I Need?
How to choose between cylinders and bulk tank gas
This depends primarily on what gas equipment you wish to use. The following are general guidelines, but please remember that if you contact us, we can work out what you will need.
Butane Cylinder
Cabinet heaters (Super-Ser is the most widely known brand) have a built-in enclosure to take a standard-size butane cylinder. Domestic cookers can also be fed from a standard size Butane cylinder.
Propane Cylinder
The next step up in terms of gas supplies is propane cylinders located outdoors, connected to an automatic changeover regulator. In the case of a two-cylinder changeover regulator, both cylinders are connected up and left turned on. The regulator will draw gas from one of these cylinders, and when that empties, it will automatically switch over to the other "reserve" cylinder. Its indicator will change from white to red to indicate that it has changed to the reserve cylinder, so that you may contact your local dealer who will call and replace the cylinder for you.
Two-cylinder automatic changeover regulators are used for gas fires. Four or six-cylinder automatic changeover regulators are used for domestic central heating systems (depending on the size of the apartment/house). Domestic central heating systems can also be supplied from a 250-gallon bulk tank (delivered by a Flogas gas tanker).
Bulk Gas
For restaurants, hotels, commercial and industrial users, the issue is somewhat more complicated. An estimate of the average usage per working hour and per week needs to be made. Usage per hour is needed because different tank sizes have a limit on how much gas they can supply (they can supply considerably more than this over shorter periods, but it is the average usage that is the limiting factor). For this purpose, and as a rough guide, the average gas usage of radiant heaters is 100% of their input rating; for other heating and water heating applications, it is 50% of the input rating; for catering equipment, it is 22% of the input rating. The input rating is both marked on the equipment and on the manufacturer's brochures. In case of difficulty, the manufacturer or Flogas should be able to help determine the average usage. You then need to estimate, from the table below, how much storage you need to supply this usage. Generally, you should keep the number of cylinders to a maximum of twelve and the number of tanks to a maximum of six in picking your choice.
In addition to this requirement, we recommend that you have enough storage to supply you for two weeks for cylinders and three weeks for tanks. You may need to increase your previous estimate to take account of this.
Container Size
There are different regulatory space requirements for the above options; for assistance, please consult the Guide for Bulk LPG Tank Separation Distances.
You may also find that you do not appear to have the space to accommodate your requirements. We have trained staff and countrywide representatives who can solve your problem over the telephone or, if necessary, by a site visit, and we would be glad to help. Please do contact Flogas.
