While squeezing your fridge against the wall might seem like a smart space-saving tactic, it could actually cost you more in the long run.
Fridges need to battle the warmth to keep your food chilled, and in doing so, they generate heat.
This heat needs a way out, typically through the back grate. If the fridge is too snug against the wall, the trapped heat forces the fridge to work overtime, driving up your electricity bill.
To avoid unnecessary energy consumption, it's recommended to maintain a gap of about 10 centimeters between the fridge and the wall.
Also, keep it away from direct heat sources like radiators to prevent extreme temperature fluctuations, which can cause condensation and ice buildup inside your fridge.
