The article deals with the influence of heat loss of the distribution piping system and the related cooling of the heating water on the design of two-pipe counter-current heating system. The heat loss of the heating water distribution system to the heated room were observed on a reference family house. Consideration of heat gains is particularly important for low energy houses. Moreover, the consequences of heat gains to the room and its effect to the required radiator power output design were solved for case when the piping distribution system is placed visible on the wall and without thermal insulation. The effect is also evident with thermal insulation or embedded pipelines. Furthermore, mass flows and temperature gradients at the same mean temperature were observed on all radiators. This calculation was compared to the results of classic calculation design.
