Give it some space!

You should leave sufficient clearance space (generally at least 50–80mm) between the wall and the back of your fridge. Always check the manufacturer’s recommendations to see if more space is needed for your model.

This helps with the energy efficiency as it allows good airflow around the condenser coils. It also allows hot air generated from the back of the fridge to dissipate.

If your fridge sits in a nook you could also install vents to aid in creating good airflow around it.

Insufficient ventilation of these coils will reduce heat dispersal and can reduce energy efficiency by up to 15%.^[1]
