In heat exchange test conditions with a heat accumulator placed in the hot water section of a heating boiler (12, 15). The heat accumulator consists of a body made of a material displaying a high level of thermal capacity and a high fusing point, e.g. cast iron, a ceramic material etc. The heat accumulator is set up to be heated via electric energy to a considerably higher temperature than the maximum temperature of hot water section.A pipe (22) containing water etc. is arranged in a heat-transmitting connection with the rising water section/hot water section of the boiler. A circulation pump (23) with the suction side in contact with an expansion vessel controls the circulation of fluid in the heat exchange relationship with the heat accumulator with such speed that the fluid is not phase transformed.<IMAGE> |
