Forum member "petengail" tells me he's getting an average of 26 days. I'm currently getting a bit less as I'm using my gas stove as well. As there are many variables these posts can only be an approximate guide.

ATM we are running the cook top and ho****er heater and getting a month out of 9kg bottle, In the scheme of thinks fridges use very little And I think it will only cut the month by a couple of days when the fridge is also on gas. It will be one of your lesser expensises

Hi Folk
My first time on the forum...so here goes.

Some gas calculations

Each Kg of gas will provide 50 Mj/hr ( Mega joules per hour )

So ..... a 9 Kg gas cylinder will produce 450Mj/h
a gas fridge has a Mj rating of approx. 1Mj/hr

So a fridge, connected to a 9Kg gas cylinder, will run for 450 hrs...or 18.7 days
( the gas burner on the fridge will run all the time )

Step one
Add the gas consumption of all the appliances

Step 2
Multipy the Kg of gas by 50 eg ( 1 only 9Kg gas cylinder 9X50= 450 Mj )

Step 3
Divide the supply of gas by the gas consumption ( Mj divided by Mj/hr )

The answer will be in hours.

My situation
The two burner gas stove in my camper consumes 13.2 Mj/hr ( that is both burners full on for hour )
I calculated we would only use it 5% of 24 hrs. (1.2 hrs )
The fridge runs 24 hrs.
The two 4.5 Kg cylinders would last 14.6 days.

The specifications will detail the Mj rating of your gas appliances.

Hope this helps

Thanks Peter

Yep I agree..thanks for the clarification.....but that many variables...where to stop and start.

The same for the gas burners, on the cook top, at some stage they would be turned down to a simmer.

My own case of 14.6 days ....I would feel happy to push that to 20 days

Cheers
