How much gas do I have left?

Your Simple Guide to Checking Remaining Gas in Your Domestic Bottle

At Gasdelivered.co.uk, we want to ensure you never run out of gas unexpectedly,

We offer a spare bottle service to ensure all your gas is used up.

The most reliable way to determine how much gas is left in your bottle is by weighing it.

Step 1: Find the Empty Weight (Tare Weight)

The empty weight of the cylinder itself, known as the Tare Weight (T.W.), is stamped into the metal collar or neck ring of the gas bottle.

• Locate the Stamping: Look for a number followed by 'kg', 'Kgs', 'TW', or 'T.W.' on the cylinder's protective collar or neck ring.

• Example: If it reads 'T.W. 12.0 Kgs', the empty bottle weighs 12.0 kg.

• Safety Note: This weight is for the empty bottle only and varies by manufacturer, so always use the weight stamped on your specific bottle.

Step 2: If Tare Weight is Missing or Unreadable

If you cannot find the Tare Weight stamped on your bottle, you can use one of these alternative methods to estimate the weight of the empty cylinder:

Option 1: Use the Maximum Tare Weight Table

Use the following table which lists the Maximum Tare Weight for common UK domestic cylinders. Using the maximum weight provides a conservative estimate of the gas remaining, helping you avoid running out.

Cylinder Size Gas Type Maximum Tare Weight (Approx.)

4.5 kg Butane 6.8 kg

7 kg Butane 8.2 kg

15 kg Butane 15.9 kg

3.9 kg Propane 6.8 kg

6 kg Propane 8.2 kg

13 kg Propane 15.9 kg

19 kg Propane 18.1 kg

47 kg Propane 38.6 kg

5 kg Patio Gas 6.2 kg

13 kg Patio Gas 15.9 kg

Option 2: Use the Full Gas Weight as an Estimate

As a quick and very rough guide, you can assume the empty bottle weighs approximately the same as the weight of the gas it holds when full. This is a simplification but provides a decent general estimate.

• Example: For a 19 kg cylinder, estimate the Tare Weight to be 19 kg.

• Full Weight Estimation:19kg Gas + 19kg Estimated Tare = 38 kg Approx. Full Weight

Step 3: Weigh Your Gas Bottle

Use a Gas Delivered scales to weigh the cylinder as it is now.

• Use the strap to carefully lift the scales.

• Record the Current Weight: Note this total weight. This is the combined weight of the bottle and the gas remaining inside.

• Example: The scales show a Current Weight of 22.0 kg.

Step 4: Calculate the Remaining Gas

Subtract the empty weight (Tare Weight or Estimated Tare Weight) from the Current Weight to find the weight of the gas remaining.

{Weight of Remaining Gas} ={Current Weight} - {Tare Weight}

• Perform the Calculation (Using 13kg Propane & Maximum Tare from Option 1):

• Tare Weight from table is 15.9 \kg.

• Example: 22.0 kg {Current Weight} - 15.9 kg {Estimated Tare) = 6.1 kg

• Result: You have 6.1kg of gas remaining in your bottle.
