In order to state the amount of heat energy produced by a solar collector or consumed by a heated floor, usually the heat transfer medium flow intensity as well as its inflow and outflow temperatures is to be measured. But these parameters are changeable during an operation. Therefore with a view to obtain more precise data, to automate the data acquisition process, the produced or consumed power and its character, the amount of produced or consumed energy at a certain period of time, the energy transformation ratio and other parameters, as well as to increase the attained data accuracy and credibility, a new heat carrier flow intensity meter has been developed and produced. Setting it with some data collecting device it is possible to determine the produced or consumed power as a function of time, and the produced or consumed heat energy in a certain time interval. The technical performance of the heat carrier flow metering system is given. Experimental investigation of the produced heat energy by the solar collector with a canal absorber, and the consumed heat energy by the heated floor panel, has been carried out using the newly developed method and some of the obtained results presented.
