What are the requirements for the ground for dry underfloor heating?

The requirements of dry floor heating for the flatness of the ground are in one sentence: to meet the requirements of flooring!

Flooring is a necessity for the decoration of every household, the floor flatness to meet the requirements of the floor is the most basic requirement of the decoration process, according to the new standard of floor paving, the two parameters of the ground flatness: the ground height difference of every 2 linear meters is less than 3 mm, and the diagonal height difference of the room is less than 15 mm. Measured with a 2-meter horizontal ruler or an infrared level.

The dry floor heating module is equivalent to a high-quality bedding treasure for laying floors, which is a harder extruded plastic insulation board, which plays a role in raising the ground, preventing moisture and improving foot feeling. Therefore, the floor type dry floor heating can meet the requirements of laying the floor, and the floor tile type dry floor heating has no requirements for the flatness, as long as there are no potholes. The construction of the dry floor heating module is very simple, 2-3 days before the floor or floor tiles are laid, and there is no impact on the decoration period, unlike the wet floor heating cement backfill and wait for 21 days to dry and maintain the ground, which is the reason why the decoration master likes dry floor heating!

Hello, the requirements are:1Confirm that the ground level meets the requirements for flooring. Reduces the hidden danger of floor noise.

2.Lay the moisture-proof mat first, then the floor heating module. Reduce the local softness of the floor and improve the feeling of stodiness on the foot.

3.More than 13 square placed in the middle of a wooden bone. The wall is smoothed with cement at the door. Reduces the potential for floor shaking.

So. The flatness requirements of paved floor heating are the basic requirements for flooring! It's quick and easy! Floor tile trench dry floor heating has no precision requirements for flatness! Hope it helps.

Dry underfloor heating - magnesium crystal prefabricated trench dry underfloor heating system

On the ground structure layer of the building, the heating pipe or heating cable is laid in the trench of the prefabricated grooved foam concrete insulation board, and the heating pipe or heating cable is consistent with the size of the groove of the insulation board and the upper surface is level, and the ground radiant heating structure of wood floor facing material or thin floor tile and stone facing material can be directly laid.

Dry underfloor heating is a thin underfloor heating that is laid with prefabricated trench dry underfloor heating modules and does not require cement backfilling. Dry floor heating module refers to an integrated floor heating module that uses multi-layer structures such as metal aluminum panels and high-density trench insulation boards.

Youyou believes that dry floor heating has the following advantages:

1. Do not occupy the height and space of the floor: the wet floor heating needs to occupy 12cm of the floor height, and the dry floor heating is installed in the gap between the floors, and the height is equal to the height of the floor, which does not affect the height of the floor and maintains a good foot feeling of the floor;

2. Fast thermal effect: the floor heating floor is directly laid on the dry floor heating module, which realizes the organic combination of radiation, conduction and convection of floor heating heat, and the thermal effect is generally 30-50 minutes to reach the floor heating design temperature (above 18 degrees); The thermal effect time of ordinary wet floor heating is generally 4-5 hours, and the heating time is shortened by 6-7 times, which is equivalent to the heating time of radiators;

3. Energy-saving, comfortable and health care: the room temperature gradually decreases from bottom to top, the heat gradient distribution is reasonable, and the energy saving is about 20% compared with the radiator; And it gives people a comfortable feeling of being warm in the head and feet, and is theoretically hygienic;

4. Controllable and convenient: it is easy to operate through the manifold, it is convenient to adjust the indoor temperature, and the indoor automatic temperature control system can be configured;

5. Concise construction: the new floor heating module process is adopted, the floor heating concrete pouring layer is omitted, and the cumbersome installation process of multi-layer composite is greatly simplified, which not only saves labor and materials, but also shortens the construction period by nearly 5 times, and can be installed one day before laying the floor, and the installation is quick and ready to use;

6. Reliable and long life: the construction adopts floor heating module and floor heating special pipe, the whole coil is installed, the hidden danger of water leakage, the quality is reliable, and the service life can reach 50 years;

7. Convenient maintenance and transformation: wet paving is inconvenient in terms of maintenance and transformation; Dry laying is easy to repair and modify, easy to modify during decoration, can be dismantled and moved to other places.

Dry floor heating, also known as ultra-thin floor heating, because compared with ordinary floor heating installation, no need for floor heating backfill, so named dry floor heating, and because there is no need for backfill layer, relative to ordinary floor heating reduction, occupy the height of the layer so also known as ultra-thin floor heating, dry floor heating module is a kind of floor heating end product laid in the dry floor heating system, popularly speaking, the dry floor heating module is made of high-density extruded plastic board, insulation layer aluminum plate, thermal conductive layer and other composite composition.

Dry floor heating is a kind of thin floor heating that uses prefabricated trench insulation floor heating modules to be embedded in heating pipes and does not need cement backfilling. The metal vapor chamber is used as the ground radiator, so that the low-temperature heat medium evenly heats the ground, and the indoor heat is heated through radiation and convection, so as to achieve the purpose of faster and more comfortable heating. Because the dry construction method is called dry floor heating, on the contrary, the wet construction of cement is called wet floor heating.

Compared with wet floor heating, dry floor heating improves the thickness of the insulation layer and the speed of the vapor chamber layer, effectively reduces the downward heat transfer loss and improves the convenience of use, which is the most energy-saving and efficient floor heating at present. According to the heat medium, it is divided into two categories: dry water floor heating and dry electric floor heating.

In winter, when the temperature drops, the indoor heating needs to be turned on. What are the advantages and disadvantages of dry underfloor heating? PChouse will take you to find out.

First, the advantages. 1. Rapid heating.

Since dry underfloor heating does not have a cement backfill, heat can be transferred more quickly, and it usually takes only 30 minutes for the user to enjoy the warmth.

2. The height of the occupied layer is small.

The floor height of dry floor heating is about 50 mm thinner than that of wet floor heating, which effectively increases the usable area of the room and is suitable for installation by household users with different floor heights.

3. The floor is comfortable.

The dry floor heating insulation layer is softer than the concrete floor, and the floor can be laid straight on top, which is more comfortable for the feet.

4. The construction is simple.

Dry underfloor heating eliminates the cement backfill step of traditional underfloor heating, and the overall installation is simple, effectively shortening the installation time.

Second, the shortcomings. 1. The material of the dry floor heating module is thin and cannot be installed under floor tiles, marble and other ground decoration materials, so it cannot be used in the kitchen and bathroom.

2. Because dry floor heating does not have a cement backfill step, it is not as good as wet floor heating in terms of heat storage effect, so it heats up quickly and cools quickly.

3. Dry floor heating is about 25% higher than general wet floor heating in terms of initial investment.

Introduction to Dry Floor Heating:

Dry underfloor heating can also be called thin underfloor heating, which is thinner because it does not have a backfill layer. Under normal circumstances, thin floor heating is mostly used for houses with low floor heights.

Advantages and disadvantages of dry underfloor heating:

Thin floor heating has the advantages of not taking up space height, heating up quickly, and easy maintenance.

There are advantages and disadvantages, thin floor heating because there is no backfill layer (heat storage layer), so the thermal inertia is poor, if the outdoor temperature or water supply temperature changes, the indoor temperature changes significantly.

Introduction to Wet Underfloor Heating:

As the name suggests, wet underfloor heating is covered with a layer of wet cement mortar mixture to make a heat storage layer. First, lay a layer of insulation board on the ground, then lay a reflective aluminum film on the insulation board, then lay a floor heating coil on the aluminum film, use a nail to fix the pipe on the insulation board, and finally lay an anti-cracking silicon crystal network on the top. Since the floor heating coil is fixed on the insulation board, the insulation effect is better.

Wet underfloor heating is a relatively mature installation process at present. The backfill layer of floor heating mainly plays the function of heat storage and heat dissipation, and the floor heating pipe buried in the ground provides heat to the room by heating the backfill layer, so as to achieve the effect of uniform heat dissipation and continuous heat dissipation by holding the virtual beam.

Advantages and disadvantages of wet underfloor heating:

Wet floor heating dissipates heat evenly and has strong thermal inertia, even if the outdoor temperature suddenly becomes cold, or the water supply temperature changes, the indoor temperature change is not obvious, and the comfort is very high.

Due to the backfill layer of wet floor heating, the height of the ground increases by about 7-8 cm after the floor decoration material is made, and if the room is short, the interior will be very depressing. Maintenance and construction are cumbersome.

The above is a detailed introduction to Youyou floor heating, I hope it will help you.

Summary. Home decoration and installation of floor heating, most people think that the laying of floor tiles is, the floor is not very suitable, in fact, it is not, but as a more complex system engineering, there are certain requirements for the laying of the floor.

The decoration and installation of floor heating in the home posture mold, most of the fierce ears think that the branches are laid with floor tiles, and the floor is not very suitable, but it is not, but as a more complex system project, there are certain requirements for the laying of the floor.

There are no requirements for the flatness of the ground before doing underfloor heating.

Floor heating leveling is to follow the horizontal line, based on the highest point of the floor elevation of the room, and make the other lower floors as high as self-leveling. If the ground is uneven, it may lead to increased energy consumption of floor heating and ground collapse. 1.

The requirement for floor flatness for floor heating is within 2 meters, and the height difference is less than 5 mm. Generally, the new houses that have just been delivered can meet the standards of floor heating installation, and there is no need to do leveling; 2.It is necessary to install floor heating and communicate with the decoration company in advance, and the water and electricity line pipes should be topped or slotted and buried, at least by sticking to the wall, and they can not be leveled; 3.

Some secondary decoration has been pried over the floor tiles, and the ground is likely to be uneven, so it is recommended that it needs to be leveled first; 4.Water and electricity pipes go to the ground, especially through the hall and through the house to walk diagonally, it is recommended that it needs to be leveled.

Whether dry floor heating and wet floor heating need cement backfill, which is fixed by ordinary insulation board clamp pipe and needs cement backfill wet construction, it is called wet floor heating; On the contrary, it is fixed with a grooved insulation board floor heating module embedded pipe. There is no need for cement backfill dry construction, which is called dry floor heating. Wet underfloor heating is the abbreviation of concrete filled underfloor heating, which is the use of insulation boards.

Reflective film. Steel wire mesh and nails fix the floor heating pipe, and use bean stone cement backfill pouring wet construction, including the standard thickness of the floor tile surface layer of 11cm, wet floor heating with cement as a homogeneous layer, need to slowly heat the ground before continuing to work, generally used for the threshold is higher, long-term need to open the floor heating occasions, the use of the proportion in the north is as high as 80%, dry floor heating is more suitable for the south of the household heating, the heating can be closed during the day, the owner saves the cost of use in the later stage!
