90 litre to 150 litre fridge gas consumption comparrison

nobody in their right mind would fit a 90l fridge in place of a 150l.
90l is not tropical rated and drop the bundle at 30c. Dometic 150l is tropical rated. All Thetford fridges are rubbish and not tropical rated for refrigeration and drop the bundle at 28c
gas consumption depends on operating ambient temperature. 9kg bottle lasts aprox 16 days.

Di this might help, but you will need to put your own figures in. Most gas appliances have a Mega joule rating, which is how many MJ are used per hour at Max output. firstly find out how many MJ per how your Frig is rated at.

A 9 Kg cylinder of gas contains 500 Mega joules. Divide the appliance hourly usage into the 500 which will equal the hours you will get out of your cylinder if the appliance is running flat out all the time. Hope that helps. Cheers

Hi Di,

We LIVE in our van we have a fridge freezer (154 or 185 litre - have to read the book again!!!) we have discovered that when free camping and running fridge and oven/gas top gas hot water ect we get approx 2.5 weeks out of a 9kg bottle (remember we are travelling with 2 kids who open the fridge 6 million times a day!!!)

Hope this helps

Cheers

Hi Di,

We have a 184litre Dometic two door fridge/freezer and when unpowered and using gas for stove, oven and hot water it uses a 9kg bottle every 11 or 12 days. We are a couple and only turn the hot water on for around 25 minutes once every couple of days for showers but I do use the oven and gas burners quite a bit, and we boil water in a billy for washing up, and all over wash on alternate days when we are conserving water.
When we are using 240 we dont have to change the bottle over for many weeks - maybe 6, not sure.

Why not just buy and fit a second gas bottle then you dont have to worry about running out. It is not a big cost compared to fuel used on a trip.

I could not live without my big fridge/freezer and it is usually as full as we can pack it as it travels better. It is one of the reasons we bought this van. Keeps the fridge well under the 4 degrees on 3 or 4 setting even when the outside temp is in the 30's.

Hope this helps you.
