Abstract

In hot water networks where there is no separate hot water circulation pipe, the problem is getting hot water to the hot water points quickly. The problem with cold water networks is the potential freezing of the cold water inlet pipe leading to the property in winter conditions. The 2-way circulation device (Device 1) has provided a bidirectional hot water circulation by means of a thin water pipe in the hot water pipe between the hot water generator and the hot water point with the hot water points closed. The 2-way circulation device (Device 2) has provided a two-way circulation of cold water by means of a thin tube to prevent the freezing of the cold water inlet pipe leading to the property when the hot water points are closed. In the present invention, these devices (Device 1) and (Device 2) are related to the inventive idea.
