Kemm tiskerf il-furnazzjoni tal-harara għal kull użu?

A sauna generally has between three and nine kilowatts of power, but after it heats up it no longer operates at full power continuously: the thermostat switches on and off, often between thirty and fifty percent of the time. A session of an hour and a half with half an hour of heating uses around 4.5 kilowatt-hours, and two hours of use comes to over 6.5 kilowatt-hours, depending on the power, insulation and how often the door is opened. This consumption varies greatly from one establishment to another, and therefore separate measurement via its own circuit is more logical than letting it depend on the general electricity account.
