Electrical equipment on thermostats goes “on” and “off” as the thermostat kicks in. It’s only the “on” time period that you pay electricity for. E.g. an electric fire may be plugged in all day but only going “on” and producing heat for half that time. Each case is different so care must be taken when estimating “on” time periods. This applies to fridges, ovens, but not light bulbs, toasters and hair dryers for example.
