How to check if you need a refill

Your home is supplied by Twin Pack bottled LPG. It is necessary to check your bottles from time to time to ensure you never run out of gas.

Your Nova Energy LPG bottle station has an automatic changeover regulator installed. When the first LPG bottle is empty, the change-over regulator will automatically switch your LPG supply to the remaining full LPG bottle.

The change-over regulator has a viewing window. When this viewing window is completely red, one gas bottle is empty. Now is the time to contact Nova and order a replacement bottle. Order your replacement twin pack online or call us on 0800 668 236.

The change-over regulator has a directional arrow, this indicates to our delivery driver which of the two gas bottles is empty. Please do not adjust the directional arrow.

These are examples of the most common types of automatic change-over regulators.

Please note: change-over regulators and pigtails (the tubing connecting the bottles to the regulator) belong to the homeowner and any maintenance is the homeowner’s responsibility. Appliances must be serviced regularly for optimum efficiency, refer to the manufacturer’s guidance in this regard and contact your local gas fitter for servicing.


See how much gas is in your LPG bottle

Please note; that to allow for the natural expansion of the LPG in warm temperatures, LPG bottles are designed to be full at 85% or just over 3/4, this is still a full 45kg of LPG.

This test will work for both 45kg LPG bottles and BBQ LPG bottles.

How to check the level of LPG in your bottle:

  1. Fill a jug with hot water from your tap; don’t use boiling water, as you might scald yourself.
  2. Pour the hot water slowly down the side of your LPG bottle.
  3. A line of condensation may appear, indicating the gas level.
  4. If it doesn’t wait a few seconds and then run your hand down the LPG bottle, where you just poured the water.
  5. You should feel a change of temperature at the level of the LPG; as the steel above the level of the gas retains the heat longer the bottle will feel warmer above the level of the LPG and cooler below.

Quick Tip: The difference in temperature will be easier to feel if you are using your LPG appliances or just after you have used them. So, if you have LPG hot water, it is best to do the test right after someone takes a shower.

For safety reasons, never open the valve on an unattached gas bottle to check for remaining gas, even if you think it is empty.


Location Test Certificates (LTCs)

In simple terms a Location Test Certificate is like the old Dangerous Good Licence.

How will the regulation changes made on 2 March 2012 affect me?

On 2 March 2012, an amendment to LPG regulatory controls was made that makes it is an offence for any LPG supplier, including Nova Energy, to deliver LPG to a site with over 100kg of LPG that does not have a current Location Test Certificate.

Because of the regulation amendment, Nova Energy needs to ensure that all affected customer sites are compliant. Nova is not able to supply LPG to non-compliant sites.

The Hazardous Substances and New Organisms Act 1996 (HSNO Act) Regulations require:

  • The “Person in Charge” of a site holding over 100kg of LPG to have a LTC issued by an independent test certifier, in order to demonstrate compliance with LPG storage controls; and
  • No supplier of LPG, such as Nova may deliver LPG to a site with over 100kg of LPG that does not have a current and valid LTC.

We will continue to keep LPG Location Test Certificate details and issue reminder letters prior to your certificate expiring.

In order to arrange a new LTC, you will need to employ an independent test certifier. You will be able to find details of test certifiers in your area by visiting the Environmental Protection Authority’s website at or call them on 0800 376 234.

You can also contact their Hazardous Substances helpline on 0800 376 234 if you use or store more than 100kg of LPG on site and are unsure if you comply with the legal requirements as set down in the HSNO Act and its Regulations.
