The invention is related to a heat exchanger collector configuration (1) allowing more efficient heat distribution within double-helix heat exchangers of heating systems by connecting the outer helix (14) with the inner helix (13) and minimizing the heat loss of water circulating within the helices. Thanks to the heat exchanger collector configuration (1), the inner helix (13) can be connected to the outer helix (14) without any deformation on its full circular structure. As the full circular structure of the inner helix (13) is not deformed, heat formed within the combustion chamber inside of the inner helix (13) is distributed equally over the helix and thereby, efficiency of heat absorption is increased.
