Is 4-8 or 8-12 pisolite better for underfloor heating in the north?

Introduction Is it better to use polka dot stone for underfloor heating in the north, 4-8 or 8-12 is better? Northern underfloor heating usually uses 8-12mm natural pea stones, because the surface of 8-12mm pea stones is smooth.

Is 4-8 or 8-12 pisolite better for underfloor heating in the north?

8 to 12.

Northern floor 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.

Whether it is better to use ceramsite or pisolite for underfloor heating backfill

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 that the thickwidth 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 multiply it by 60.

What is the difference between leveling pea pits and leveling melon seeds for underfloor heating?

Ceramsite is better.

There are four reasons:

First, ceramsite is usually shaped like a ball with rounded edges and no edges , so it will not affect the floor heating pipe and the damage caused by floor heating materials.

Secondly, ceramsite is bulkier and lighter than pea stone, which can not only reduce the load on the ground, but also facilitate the process of embankment construction.

Third, the price of ceramsite is cheaper than thishim pea stone, and underfloor heating is usually installed throughout the house, so the cost of using ceramsite backfill is much lower.

Fourth, ceramsite has good heat dissipation performance and is conducive to energy saving.

The main reason is that ceramsite has better sound and heat insulation effects, is lighter and has less heat loss, so the materials used for floor heating are better .

In addition to preparing ceramic stones, you also need to prepare other materials, such as cement, sand and other materials. Floor heating filling material mainly refers to the heat storage layer, which can effectively dissipate heat and achieve optimal result. good heat storage.

What issues should be considered when buildingtion of underfloor heating backfilling:

1 During the underfloor heating backfilling process, the area poured each time should not be. too large to avoid cracks in the concrete, when constructing the concrete backfill layer.

The water pressure in the heating pipe should be greater than 0.6 MPa. During the maintenance phase of the backfill layer, the system water pressure should be greater than 0.4 MPa. If it is too low, it will cause inconvenience. affect the normal process.

2. When constructing the concrete filling layer, it is strictly prohibited to use mechanical vibration equipment to avoid damage to the floor heating pipes. Construction workers must wear flat shoes with soft soles and drilling is strictly prohibited. prohibited in areas where heating pipes or transmission cables are laidion.

3. Before the system is initially heated, the concrete fill layer requires a curing period of over 7 days. The thickness of the heating tube filling layer should not be too thick, otherwise it will occupy the height of the layer and cause the thermal effect to be too slow. During the concrete curing process, it is best to close doors and windows, which can effectively maintain moisture on the concrete surface, but be careful not to accumulate water afterwards. 72 hours of curing.

How much does it cost to level 2.5 cubic meters of pisolite for underfloor heating?

The softness of pisolite will not damage the heating pipes by the ground, 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 backfille underfloor heating to protect the 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.

I would like to ask if pisolite is needed for underfloor heating backfill?

The ratio of the material is 1:2:3.

The material ratio of cement, pisolite and yellow sand in floor heating leveling is 1:2:3. Because underfloor heating leveling is special, in addition to cement and yellow sand, it is also. It is necessary to add certain spaces between the pea cores, which is more conducive to floor heating and heat dissipation.

Sanding or cracking is more likely to occur after leveling underfloor heating. Sanding is due to the insufficient strength of the concrete floor. Everyone should pay special attention to the dosage. The causes of cracks are multiple.

It is not possible to use pisolite when backfilling underfloor heating. Pay attention to the proportion of pisolite cement. The general ratio is 1 (cement) to 2 (pisolite) to 2 (sand). be careful to leave room for expansion around the room, the day after backfilling, sprinkle water on the backfill layer for curing.

The reason for using pisolite is that the heat generated by the floor heating pipes must also be dissipatede. Try using pisolite or guarmistone. The leveling layer will contain many bubbles, forming gaps, and heating. will follow him.
