The floor heating water inlet pipe does not supply water, and the floor heating is not hot. After the inlet and outlet exhaust valves are opened, air is often sucked in, and there is water at the well head of the floor heating pipeline.

When the exhaust valves of the intake pipe and the exhaust pipe are opened, they suck in air. It is possible to consider the floor heating backwater. The water in the return pipe flows back from top to bottom, resulting in negative pressure, which causes the valve to suck air.

If the floor heating is not turned on in winter, pay attention to the distribution manifold.

Due to the weather, the distribution manifold will freeze and rupture. Therefore, when the temperature reaches below zero, all the water in the distribution manifold must be blown out by an air compressor. If the water is not blown out, it will freeze inside and expand after freezing, thus blocking the pipeline.

Floor heating is by far the most comfortable heating method. The indoor surface temperature is uniform, and the room temperature gradually decreases from bottom to top, which gives people the comfort of warming their feet and cooling their heads, and conforms to the fitness theory of "warming their feet and cooling their heads" in traditional Chinese medicine.

In addition, the floor heating naturally rises due to hot air, and there is no air agitation, which is not easy to cause foul air convection, and the indoor air is clean and hygienic.
