[header] How to improve the energy savings of your fridge or freezer [title] Avoid placing a fridge or freezer near heat sources. [step] The most common source of heat in a kitchen is the oven and the dishwasher, but some kitchens also have a water heater in place as well. Keep the fridge or freezer well away from these heat sources. 
If you situate a fridge next to an oven, for example, the fridge will over-compensate for the heating up. For the same reason, it is also important to avoid placing a fridge or freezer in direct, constant sunlight.
