Claim:
1. A method of measuring the heat flow through a structure having a thickness, which construction comprises a first surface having a first surface temperature, and a second surface located on the opposite side of the construction relative to the first surface, wherein a temperature difference is formed transversely through the thickness of the construction, between the first and the second surface, wherein at least two temperature sensors are connected to the first surface, at least one first temperature sensor is insulated thermally from the second temperature sensor, so that the temperature, which is detected by the thermally insulated sensor, is affected by the heat flow through the construction more than the temperature, that is detected by the second temperature sensor, and the temperature difference between the second sensor and the first sensor is determined, wherein in order to reduce the temperature difference, and based on the amount of energy that is supplied to or discharged from the first sensor, the heat flow through the construction, which heat flow depends on the temperature difference through the construction, is determined.
