1. Floor heating drainage can effectively avoid air blockage in floor heating, thus achieving better heating effect. If there is gas in the pipeline, it will lead to gas blockage in the pipeline and affect the circulation of hot water to some extent. Therefore, it is necessary to ventilate the floor heating every once in a while and exhaust all the air in the pipeline.

2. If the floor heating works for one to six hours, it takes ten minutes to exhaust and drain, while the floor heating works for twenty-four hours, and it takes half an hour to exhaust and drain. If it is not heated, it needs to be thoroughly cleaned. If the heating stops suddenly during the heating process, the water in the pipeline must be drained to prevent the pipeline from freezing. If you don't change the hot water for a long time, it is likely to produce bacteria, so you should drain water frequently.

3. Compared with traditional heating methods, floor heating has many advantages, and it has the characteristics of comfort, health, energy saving and environmental protection. In foreign countries, this technology is widely used in public buildings such as civil houses, medical institutions, swimming pools, gymnasiums, shopping malls and office buildings. It is also widely used for thermal insulation of building systems such as factories, hangars, flower beds, football fields and vegetable greenhouses. And even used for snow melting of outdoor roads, roofs, stairs, airport runways and various industrial pipelines. More than 50% of new buildings in developed countries in Europe and America have installed radiant floor heating.
