<p>A solar accumulator with a plane solar heat collector of the kind which emits radiated heat to an accumulator tank containing a heating fluid in a pressure free condition and at least one heat exchanger coil is arranged in said accumulator tank. The collector comprises an external transparent covering means for the incident radiation disposed at a selected distance from a radiation absorbent surface, which comprises one wall of the accumulator tank comprising a material having a good thermal conductivity convection preventing elements defining a plurality of closed air spaces are disposed between the covering means and the absorption surface. A high effective insulation is applied directly against all sides of the accumulator tank, with the exception of the absorption surface.</p> |
