Common misunderstandings of floor heating floors, advantages and disadvantages of floor heating floo

Myth 1: The thicker the dough, the better.

In the process of purchasing floor heating floors, some consumers blindly pursue the thicker the multi-layer parquet skin, the wider the floor, the better, and the longer the floor. In fact, the thicker the skin of the multi-layer parquet, the more pronounced the characteristics of the parquet floor. In the process of environmental change, the greater the stress generated by the skin when the floor shrinks and swells, and the chance of floor deformation and cracking increases.

The wider the multi-layer parquet, the larger the gap will be when it shrinks. Similarly, since the multi-layer parquet expands and contracts in both the length and width directions, the longer the multi-layer parquet, the larger the gap at the end of the floor when it dries out.

Therefore, the dough of the multi-layer composite floor used for geothermal heating should not be too thick, the geothermal floor veneer of South Korea and Japan is more, most of the enterprises in China produce it, and the standard board surface layer produced by the living home is very suitable for the type of floor heating floor, which is very popular in the north where geothermal heat is frequently used. If you choose a multi-layer solid wood floor with thick leather (3 4mm) as a geothermal floor, the width of the floor is less than 70mm or the humidity of the use environment can effectively control the deformation of the board surface. The diagram below shows the different deformations of the floor with a width of 125 mm and a thickness of 4 mm, 3 mm and 2 mm.

Myth 2: It is best to have a large groove on the back of the floor.

Some people think that the geothermal floor backsheet is well grooved, which is conducive to the flow of hot gas, and even makes the floor backsheet a hollow structure. In fact, the conduction velocity of heat in solids is faster than that of gas, and the higher the density, the faster the heat conduction, which is one of the reasons why we increase the density of flooring substrates. The longitudinal groove on the back of the surface forms an air layer at the groove on the back of the floor, which reduces the heat conduction effect because the heat conduction velocity of the air is lower than that of wood.

Myth 3: The moisture-proof film is the best for heat penetration.

Some flooring installation companies do not stick the moisture-proof film connection tightly when installing the floor, and some installation companies even cut the moisture-proof film into many small openings in order to breathe and improve the heat conduction effect. Generally speaking, after the completion of the geothermal project, the moisture content in the ground cement is at least 17% or more, and the moisture of the ground is continuously emitted outward during the geothermal heating process, which directly acts on the back of the floor through the damaged moisture-proof film, resulting in the floor delamination, bulging and exploding paint. In addition, in the later stages of winter heating, the heat conduction velocity of the ground slows down due to the excessive reduction of moisture in the ground, resulting in a low room temperature.

Therefore, not only do we not cut the moisture-proof film into many small openings, but also glue the moisture-proof film tightly with plastic tape to ensure that it is not breathable. This can not only avoid the harm of moisture in the ground to the floor, but also keep enough moisture in the ground to ensure the heat conduction effect in the later stage of winter heating.

First, the advantages. 1.Healthy and comfortable:

Underfloor heating can provide a hot amount of heat to make the indoor floor temperature uniform. As the saying goes, "warm people first warm their feet", and floor heating, a scientific heating equipment, can give people the comfort of warming their feet and cool their heads, and can also improve people's blood circulation. And there is no pollution caused by air convection, so the air in the house can be cleaned.

2.Space-saving: No radiator increases usable area, which can make the room beautiful and tidy.

3.Power saving: high floor heating efficiency, low heat loss, 20% less than other heating equipment, saving 20% of operating costs.

4.Good thermal stability: The aluminum foil layer of floor and floor heating stores a large amount of energy and has good thermal stability, which can keep the indoor temperature stable even if it is intermittent.

5.Long service life: The service life of qualified floor heating pipes is more than 40 years.

Second, the shortcomings. 1.There are dead corners in the use of space: the heating pipe used for floor heating is often complicated, and the use of small space is limited, because the coil should be waterproof, and it is difficult for a small space to meet the heating standard at room temperature.

2.After 2-4 years of underfloor heating, the pipes are prone to fouling and need to be cleaned by professionals and professional equipment. If the scale is not treated, it will affect the heating effect.

3.The floor height is occupied. The floor heating insulation board is 30mm, the filling layer is 50mm, and the total thickness is 80mm, which has an impact on the layer height.

Advantages of floor heating: comfort, health, health care: the full name of floor heating is low-temperature radiant floor heating, it is by far the most comfortable heating method, the indoor surface temperature is uniform, the room temperature gradually decreases from bottom to top, giving people a comfortable feeling of warm feet and cold head; Because the hot air rises naturally, there is no air agitation, it is not easy to cause polluted air convection, and the indoor air is clean; Improves blood circulation and boosts metabolism.

2. Floor heating does not occupy space, and the use of the living room is more flexible: Floor heating is a concealed project, and there is no radiator and branch pipe to occupy space, which increases the usable area of the living room from the side.

3. Superior energy saving: the radiant heating method of floor heating has higher thermal efficiency than the convection heating method, and the heat is concentrated in the height of the human body; Small heat loss during transmission; Users can also flexibly adjust according to their own usage to further effectively save energy.

4. Good thermal stability: the ground layer and concrete layer of floor heating have strong heat storage capacity, and the indoor temperature changes slowly under the condition of intermittent heating.

5. Low operating costs: about 20% energy saving compared with other heating equipment, which can make full use of low-temperature hot water resources or use electricity price policies to reduce operating costs.

6. Long service life: the plastic pipes or heating cables used in floor heating are buried in the ground, with good stability, no corrosion, no human destruction, and the service life is synchronized with the building. It can also save maintenance costs for users.

Disadvantages of underfloor heating:

1. Floor heating does not occupy space and occupies the floor height: floor heating occupies a floor height of 5-7 cm (the selection of insulation materials, floor heating pipes is different, the construction plan and method are different, and the impact on the floor height is different).

2. It is not easy to maintain: floor heating is a hidden project, and materials with good pressure, temperature and corrosion resistance and good thermal stability should be selected when decorating. It is not convenient for secondary decoration, because the pipeline is laid underground, and when the ground is transformed, it is easy to damage the underground pipeline.

And it is not suitable to lay decorations on the floor, which is easy to affect the heat dissipation effect.

3. The use of the toilet is limited: due to the complexity of the heating pipeline of the floor heating, for the sake of waterproofing, the floor heating coil must be waterproof before and after laying, due to the small laying range of the bathroom (such as to reserve the toilet, bathtub, drain, etc.), the room temperature often does not meet the heating standard, and it needs to be supplemented by radiators.

4. When the floor heating system is in operation for 2-4 years, the floor heating pipeline produces scale, which needs to be cleaned by professional equipment, otherwise it will directly affect the heating effect.

This episode of the program shares the experience of using floor heating, and compares electric floor heating and water floor heating in all aspects of cost maintenance. This is the last episode, and the next episode will introduce the installation and precautions of floor heating construction.

This is a question that can easily be found in the floor as long as you follow what happens when it is heated

1. Environmental protection, long-term high temperature will release a large number of harmful substances in the floor, the first formaldehyde in the floor is a strong adhesive, formaldehyde is the main component of strong adhesive, and the release cycle of formaldehyde is 3-15 years.

2. Deformation, the floor heating environment temperature is high and changes rapidly, and the fiber structure of the wood floor is prone to irreversible deformation.

3 heat dissipation, floor heating on the floor must not hit the keel!! Wood is a poor conductor of heat, and the temperature of the place where the floor is laid on the floor heating is definitely lower than where the floor tiles are laid.

These are the three most important points.

In Japan and South Korea, floor heating is more popular, in order to avoid the above situation, stone plastic flooring is generally used to match floor heating. Shenxing ECO flooring is a home-improvement grade stone plastic flooring, with: environmental protection, completely free of formaldehyde and other harmful substances; Dimensionally stable, no deformation; The heat dissipation is fast and even, and the heat dissipation is close to that of the tile.

Not afraid of water, easy to take care of.

A qualified underfloor heating floor must have three major characteristics.

First of all, the thermal conductivity and heat dissipation should be good, "it should be thin but not thick". Wood and bamboo are good natural materials, and there will inevitably be heat loss from the floor to the surface through the floor, which can be minimized by an ideal floor. Therefore, in order to reduce the loss of heat energy and reduce the cost of heating operation and maintenance, the thickness of the plate should not exceed 8 mm, and the maximum should not exceed 10 mm.

Secondly, the stability of the material should be good, and the use environment of the floor heating floor is complex, especially in the northern region, the ground has to withstand various moisture in the non-heating season, and the ground temperature has to rise suddenly during heating, and the floor must bear the double change of "temperature" and "humidity". Therefore, floor heating floors must be made of materials with good stability.

Finally, wear resistance is required to be long-lasting. Due to the general thickness of the floor heating floor, it is better to conform to the surface layer to even millimeters, and the wear resistance value of the paint on the main surface layer is higher than that of the traditional index.

Floor heating should not be made of solid wood floors, or floors that require a keel. Moisture baking is not very dry in the production of solid wood flooring, and the floor heating is baked for a long time, which may lead to the drying of moisture It is recommended to purchase wood floors suitable for floor heating.

The use of underfloor heating in the home will have an impact on the wooden floor. The ground radiant heating system is mainly based on the ground as the heat dissipation surface, the whole room for low-temperature floor radiant heating, the floor heating room floor material selection from the thermal conductivity considerations, natural stone is the best, followed by ceramic tiles, then composite flooring, and finally wood flooring. So in the same case, wood flooring has the most thermal insulation and relatively poor heating effect.

Sometimes, due to the lack of dryness, the moisture in the solid wood floor is too large, which may cause the floor to warp and bulge when applied to the floor heating room. Due to the large amount of glue contained in the composite floor, it is easy to activate harmful substances such as formaldehyde and benzene when heated, which is not good for people's health.

Now there is a special floor heating floor, the heating effect is very good, and the beautiful high-end atmosphere is high-grade, and it is very comfortable to step on. Later, I will send you the top ten brands of floor sales in 2018 for your reference.
