It should be noted that in places where the floor heating pipes are relatively dense, for example, the spacing is less than 10 cm, it is best to add a thermal insulation pipe. Because the pipeline has both water supply and return water, we all know that the temperature of the water supply is the highest, and the temperature of the return water is reduced a lot after the circulation. Heat exchange, if the heated hot water is cooled by the return water, the effect is not very good. The floor heating pipe has a practical trick when it comes to crossing the expansion and shock joints of the house. Of course, it would be best if the expansion joints and anti-vibration joints could not be crossed. If this is absolutely necessary, it is best to add a flexible casing to the outside of the floor heating pipe. Because the wall structure of the house is subject to thermal expansion and contraction, if it is firmly combined with the floor heating pipe, it will have a pulling or compressing stress on the floor heating pipe, which is not good for the floor heating pipe. If a flexible sleeve is added Well, this problem won't exist anymore. The deformation of the cement when the house structure expands and contracts when the temperature is cold will only pull and compress the flexible casing, and the flexible casing and the floor heating pipe can move, so that the floor heating pipe will not be deformed.
