Things That Affect The Amount of Gas Required


Larger fridges require the use of more gas, as they are designed to be able to keep more things cool. The size of the fridge you will need depends on how big your family is and what you put in it. If you are on your own, a smaller fridge that uses less gas will be enough, but if you have children and a partner you will require more gas and a larger fridge.

Method of Installation

The method of installation of the fridge will also affect the installation. Air must be able to flow over the condenser for a caravan fridge to be able to work, and the more freely the air runs through, the less gas you will require. Other things that affect how much gas is required for your fridge are the ambient temperature of the van, the wind on the side of the van, how many times you open the door and how long you open the door for all affect how much gas you use.

Examples of Amounts of Gas Used

Smaller units will use around 187 to 257 grams over the course of a full 24-hour day. If you use maximum cooling with your fridge, you will be using a higher rate. Using these numbers, we can see that a 4.5-kilogram Calor gas bottle will last a few weeks. If you are only using 200 grams for your fridge, then that bottle will last 22.5 days, so then you will be using around 72-78kg of gas per year.

A larger fridge-freezer, such as the Dometic RMD 8555 will use about 380 grams over the course of 24 hours if the temperature is around 25 degrees Celsius.

Thetford N175 fridge freezers will use about 23 grams per hour, and sometimes it has been quoted as using 480g a day when the fridge has been running constantly and the ambient temperature is 24 degrees Celsius. A 4.5kg bottle will then last around nine days, This means that in a year you can expect to use around 175.5 kilograms of gas in a year if you have or choose to purchase a Thetford.


We have seen that multiple factors affect the amount of gas required to keep your caravan fridge running. If you are always opening your fridge and you keep the fridge open for a long time, you will be using more gas. Your caravan’s temperature and the wind also will change how much you require, as well as the size of your fridge.
