At present, when most families install floor heating pipes, they are almost inseparable from these 4 categories, which are 16, 20, 25, and 32 respectively. The number mentioned here generally refers to the outer diameter, in millimeters, so the larger the number, the thicker it is. So you can see the thickest geothermal pipe, which is 32 mm in our commonly used specifications.
When talking about the common specifications of floor heating pipes, another concept needs to be implanted, that is, the thickness of the inner wall. Because the real anti-pressure is not determined by the thickness, but by the thickness of the inner wall. Therefore, if you are more concerned about anti-pressure, you also need to pay attention to the wall thickness when purchasing geothermal pipes.
The thicker the floor heating pipe, the higher the installation height and the more sediment filling cost. Therefore, in general families, 20 and 25 gauge floor heating pipes are basically used.Generally speaking, 20 floor heating pipe will be used for coil installation, and 25 floor heating pipe will be used for main pipe installation. This is just like the PPR pipe. The main pipe increases the water flow during the water delivery process, which can make the water in the branch pipe flow back faster and make the heating and insulation more stable.
