Temperature Control

A classic energy saving tip is to set cooling at 24°C (or more) and heating at 20°C (or less). Every extra degree of heating or cooling uses around 10% more energy.

So what about heaters / coolers that don't have a temperature settings? Today I found out about plug-in thermostats.

They do just what they say. Sitting between the power point and the heater or cooler, they sense the temperature of the room and turn off the power when the room is at the right temperature. Automatic energy savings.
