How Do I Know If My LPG Bottle Is Empty?

A shower running cold mid-bath is never a welcome change. And it’s just as frustrating when your heating appliance or gas hob stops without a hint, because you’re suddenly out of gas. You can stop this annoying thing from happening again if you know when your LPG bottle is running low.

Help is here as we’ll show you an easy way to check when the bottle is about to run empty – so you can keep your gas supply going.

How long does a LPG bottle last?
For a family of two adults and two children, a 45kg bottle used for both hot water and gas cooktops will typically last about 6-8 weeks. It’s a different thing if you add a gas-fired space heater.

Gas cylinders typically have a change-over regulator (reg) installed between them. Some cylinders have an automatic reg that switches from the empty bottle to the full one when the first runs out. Other cylinders have a manual regulator, which you will need to turn by hand to switch to the reserve bottle.

The change-over regulator usually has a viewing window or an indicator. When both bottles are full, the indicator will be Black, Green or Clear. When one bottle is empty, the indicator will be RED. The reg will have a change-over valve and a directional arrow. If your regulator is manual, do not adjust the directional arrow. Many people mistake it for the change-over valve, but the arrow simply indicates which bottle is empty.

It’s a good idea to regularly check the indicator on the change-over regulator, so you can call us when one bottle is empty.

How to test the level of LPG in the cylinder
One way is to pour warm (not boiling) water down the side of the bottle. Wait a few minutes, then run your hand down the side of the bottle. The level where it feels cool to the touch indicates how much LPG is left.

This is a fairly accurate method, but there’s an easier and faster way – using a LPG cylinder weighscale.

gas_bottle_scaleThis is an innovative sensing device that monitors bottled gas levels and automatically sends an accurate reading of the remaining gas in the cylinder. The weighscale is installed underneath your LPG cylinders. We can set them up for you, and once they’re there, checking your cylinders will be one less thing to worry about.

The device is also tied to a mobile app, which you can  access to get detailed daily usage reports or prompts when your cylinders need a refill. You never need to guess the gas level as there are easy to view visuals and graphs for the remaining LPG. As the supplier, we also have this data in the app, so we’ll also know when to deliver the next cylinder so you can keep your gas going without interruptions.

This works for both residential and commercial applications. For more information about this new technology, a chat or call is most welcome. Get in touch with Hot Water Cylinders NZ!
