The pea stone is smooth and will not damage the floor heating pipe, but the price is relatively high.
1. The smooth button stone will not damage the floor heating pipe, but the price is relatively high. Pisolite concrete uses pisolite as underfloor heating backfill to protect underfloor heating coils. The natural silicon content of pisolite gives underfloor heating better thermal conductivity. The price of floor heating leveling is as low as 50-80 yuan/㎡, while the most expensive price is 100 yuan/㎡ or even more.
2. Melon seed slices are cheap, but their irregular shape and sharp edges will scratch the heating pipes during the construction of the underfloor heating embankment and during their subsequent use. Over time, there will be hidden dangers of water leakage.
Why use pea stone forunderfloor heating embankment?
As long as you strictly follow the construction process, everything will be fine. Mix the cement, sand and pisolite evenly in proportion, then spread them evenly on the pipe. Bury the underfloor heating pipe at least well, about 3 to 4 cm. Choose a manufacturer with reliable quality and good reputation for pea stone, because the quantity will not change after one use, so the quality should be good. The quality of floor heating pea stones from Shandong Yihe Pebbles is good and trustworthy. The floor heating pebbles from Linyi Cobblestone production base are also very good and are usually packed in 50kg woven bags. The bulk density of pisolite is approximately 1.7 per cubic meter. Why is pistone used for underfloor heating backfill? Shandong floor heating pisolite manufacturers wholesale and retail,with uniform specifications and particle size standards. It is the industry leader of floor heating embankment pisolite, Shandong Yihe.
How much pisolite is needed for 60 square meters of underfloor heating?
Pisolite material has no sharp edges or corners and the surface is relatively smooth. It is generally used. when there are buried pipes, such as underfloor heating or cable trenches.
Complete the construction of the concrete filling layer within 48 hours after the installation of the floor heating pipe and the water pressure test is qualified during the construction of the layer of concrete filling, the water pressure in the heating pipe; must not be less than 0.6 MPa. When maintaining the filling layer, the system water pressure should not be less than 0.4 MPa;
The filling layerPadding is a structural layer used to protect plastic pipes and maintain floor temperature. uniform. Usually it is pisolite concrete, the grain size of the stones should not be more than 10 mm, the volume ratio of cement mortar should not be less than 1:3, and the degree of strength of the concrete should not be less than C15. The thickness of the filler layer should meet the design requirements, and the flatness should not exceed 3mm.Detailed information
Features of underfloor heating
1. Comfortable and healthy. The temperature of the floor heating goes from low to high, giving people a comfortable feeling of warm feet and cold head, which conforms to the theory of traditional Chinese medicine. Heat is mainly transferred in the form of radiation, which does not dry the air. The wavelength of the radiation is far infrared8 to 12 microns, which is beneficial to the human body.
2. Energy saving and environmental protection. To achieve the same room temperature effect, it can be set 2-3 degrees lower than traditional heating, effectively saving energy. And it will not pollute indoor air.
3. Uniform and stable heat dissipation. Since underfloor heating transmits heat through the concrete, the heat is distributed evenly. In addition, concrete has an energy storage effect, so the room temperature can remain stable even if heating is intermittent.
4. Reduce floor noise. Floor slabs in China generally use prefabricated panels or cast-in-place panels. The sound insulation effect is extremely poor. People going up the stairs will affect people downstairs. The use of underfloor heating to increase the layer of insulationation has a very good sound insulation effect and can reduce noise pollution. The floor heating process is quiet, the indoor environment is quiet. , and there is no air conditioning noise. This is beneficial. Help children focus on learning, thereby improving learning efficiency.

Are 4-8 or 8-12 pisolite better for underfloor heating in the north? Easy to use
About 0.9 cubes of pea stone. Usually, one square meter of underfloor heating backfill requires 0.015 cubic meters of pisolite, because one square meter of underfloor heating backfill requires cement, sand and pisolite, and the quantity ratio is 1: 2:3. Assuming the thickness of the embankment is 0.03 meters, the total volume is 0.03 cubic meters. The volume of each portion is 0.005 cubic meters, we phad therefore to calculate that the pisolite is 3 times 0.005 equal to 0.015 cubic meters. Then multiply it by 60.
8 to 12.
Northern floor heating generally uses natural pisolite from 8 to 12 mm, because the surface of 8-12mm pisolite is smooth, without edges and corners, and the particle size is uniform.
Pisolite refers to a kind of modern-day building material. It is a stone the size of a soybean. It is generally used for floors and roofs. The particle size is similar to mung beans and is called stone powder in some places.
