Method for investigating hot water leak in floor heating system

摘要

An object of the present invention is to identify a leak point from a hot water pipe covered with a floor material. A method for investigating hot water leaks in a floor heating device is a method for investigating hot water leaks in a floor heating device having a hot water pipe disposed on a lower side of a plurality of floor members 52 joined in a horizontal direction of a building. Applied. A replacement step of replacing the water in the hot water pipe 38 with a gas lighter than air, and a probe 62A of a helium gas detector 62 for detecting a gas lighter than air, is provided between one floor material 52 and another floor material 52. And a gas detection step of moving along the joint. [Selection] Figure 8
