8 to 12.
Northern underfloor heating generally uses natural pisolite of 8 to 12 mm, because the surface of pisolite of 8 to 12 mm 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.
How many pea stones are needed for 60 square meters of underfloor heating?
Special pea stones for backfilling underfloor heating should have a size of 'approximately 10 mm and a smooth surface. and without edges. Only the smoother ones have better thermal conductivity. It can better play the role of Linyi paving stone production base in Shandong Province, a piso producerlite for underfloor heating, which uses natural pisolite, which is screened twice. kilograms. According to the ratio of cement, sand and pisolite, it is 1:2:3. Say the important things three times, 10mm, 10mm, 10mm.
What is the difference in thermal conductivity between underfloor heating backfill pisolite and melon seed slices
Approximately 0.9 cubic meters of pisolite. 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, so we can calculate that pisolite is 3 times 0.005 equal to 0.015 cubic meters. Then just multiply it by 60.
Is it better to use ceramsite or pisolite to level underfloor heating?
Melon seed slices: Melon seed slices are inexpensive, but their irregular shape and sharp edges can cause problems when ground leveling. construction of heating embankment. And if the heating pipe is scratched during further use, there may be a risk of water leaking over time.
Pisolite: A stone similar to the size of a bean , it is therefore called pisolite. Its shape is rounder than melon seed slices and will not scratch. Heating pipes are an ideal filler material. They have better thermal conductivity than melon seed slices.
What is the best filler material for ceramic pea stones. for underfloor heating?
Polka dot stone is better. Discovered according to Qijia.com query.
1. Pisolite can prevent serpentino damage to the floor heating and make the temperature of the floor heating more uniform. The surface of ceramsite is rougher than gravel and has a lower water absorption capacity.
2. Pisolite can increase thermal conductivity and has a hard texture. The price of ceramsite is high and the cost of subsequent maintenance is also high.
The backfill material for underfloor heating can be ceramsite or pisolite, both of which have certain advantages and disadvantages.
Ceramsite is a porous clay-based material. It is lightweight, has low water absorption, good air permeability, and is not prone to mold growth. Its use of backfill in floor heating system can better promote heat dissipation to the ground, conduct conduction and radiation more evenly, and improve temperature stability andenergy efficiency of the underfloor heating system.
Pisolite is a natural granular mineral material with thermal inertia. It has strong characteristics and can maintain the heat of the floor heating system to a certain extent. Pisolite also has good drainage properties and is often used to improve soil structure and increase the air permeability of the soil.
