What is the thickness of the floor heating and how much floor height is occupied by the floor heatin

What is the thickness of the floor heating screed - the floor height of different types of floor heating.

Traditional floor heating is actually what we usually call water floor heating and electric floor heating. After this kind of floor heating leveling, the overall thickness is generally about 7-8cm. Thin floor heating is actually water floor heating, but unlike traditional water floor heating, its laying method is simpler, directly using a grooved insulation board to fix the floor heating pipe, generally does not need cement leveling, so the floor height is generally only 3-5cm.

In order not to cause indoor depression, the installation of floor heating requires the floor height of the room not to be lower, among which for the user whose room is lower than that, it is recommended to install thin floor heating, and the floor height of the room is more than 3m, so there is no need to worry about the thickness of the floor heating leveling. If your room is below the ceiling height, you can use radiators to heat your room. The comfort of radiator heating is second only to floor heating, and much higher than that of air conditioning, which is the best heating method for users who do not have the installation conditions of floor heating.

Shanghai Nuanfeng graphene electric floor heating does not occupy the height of the floor, the thickness of the floor heating is only a centimeter thickness, and the bottom insulation layer is only 1 cm thick, and the wooden floor can be directly laid on it. In this way, the thickness of the entire floor heating and wooden floor can be added together to about 2 cm, and the house with low floor height and the family with a small area are very suitable for choosing electric floor heating. Plumbing and floor heating take up a lot of boiler space, not to mention, the annual maintenance cost is about 1,000 yuan.

In Shanghai, every inch of land is valuable, if you are a small house in the ** area, it is worth considering using our Shanghai Nuanfeng graphene electric floor heating. Nuanfeng floor heating has a good reputation, many large residential areas have been installed and used for many years, product quality is stable and reliable, energy saving and environmental protection, and the product life is almost the same as the building. More details can be found here.

Floor heating 18 degrees up to standard.

The state clearly stipulates that the indoor heating temperature is above 18 degrees Celsius, and if the room is to be warm, the temperature of the inlet and outlet water for heating is usually like this. Underfloor heating: The inlet water temperature is 60 degrees Celsius, and the return water temperature is 40 to 50 degrees Celsius.

Radiator: The inlet water temperature is 80 degrees Celsius, and the return water temperature is 60 degrees Celsius.

Keeping the water supply temperature and the water supply and return temperature difference low is conducive to extending the service life of the plastic heating pipe. It is beneficial to improve indoor thermal comfort. It is beneficial to maintain a large flow rate of the heat medium and facilitate the removal of air in the pipe.

It is also conducive to ensuring the uniformity of ground temperature. It will also be more energy-saving and environmentally friendly, and the higher the temperature regulation, the greater the energy consumption.

Underfloor heating

Floor heating is the abbreviation of radiant floor heating, which uses the entire ground as a radiator, evenly heats the fiber floor with a low-temperature heat medium not higher than 60 degrees Celsius, and provides indoor vertical heating through the ground in the form of radiation and convection heat transfer to achieve the purpose of comfortable heating. According to the thermal medium, it can be divided into two categories: water floor heating and electric floor heating, and according to the pavement structure, it can be divided into wet floor heating and dry floor heating.

Ground radiant heating is mainly divided into water floor heating and electric floor heating according to the different heating methods, and electric hand guess floor heating is divided into heating cable heating and electric heating film heating carbon fiber electric heating. Geothermal heating is a heating method in which hot water or heating cables with a temperature of no higher than 60 degrees Celsius are buried in a coil system under the geothermal floor to heat the entire ground, and the heat is evenly radiated to the room through the ground.

Laying floor heating will definitely affect the height of the floor, and water floor heating will occupy 2-3 cm more than electric floor heating (graphene electric heating), which is the diameter of the water pipe. After the floor heating is laid, due to the long service life, in addition to comfort, it is necessary to ensure safety, and the following is a simple explanation for the laying of floor heating:

Insulation board 2-3 cm: The purpose of laying the insulation board is not to let the heat lose downstairs, it is best to choose the insulation board above B1 grade for laying, if it is the first floor because it is close to the ground is easy to return to moisture, so it is recommended that the thickness of the insulation board should be 4-6 cm.

Negligible thickness of the reflective film: The purpose of laying the reflective film is to reflect the heat to the ground as much as possible.

Water floor heating water pipe diameter 2-3 cm: please choose the most qualified water pipe for laying, otherwise the pipe burst will outweigh the loss.

Electric floor heating The thickness of the graphene electric heating film is negligible: please choose a reputable manufacturer, and each piece of electric heating film can be heated evenly without attenuation.

Backfill cement layer 3-4 cm: Some people in order to reduce the height of the occupied layer to use dry paving not backfill cement, I personally do not agree, backfill cement has 2 main purposes: 1

Thermal storage and heat preservation 2Increase the hardness of the ground and avoid stepping on the water pipes or heating film. (Insulation board or extruded board is made by extrusion of polystyrene resin and other additives, and the hardness is limited).

Lay 1-2 cm of wooden flooring or tiles for underfloor heating.

Therefore, the laying of graphene electric underfloor heating occupies about 6-8 cm of floor height.

Floor height of floor height: 8-10 cm.

Hope mine can help you!

According to the national standard, the temperature of the heating air in winter and the actual use habits of users should be controlled at 18 to 22 per day, and it is recommended to set the temperature in different functional areas of the living room, such as the indoor temperature range of 18 to 20; Bedrooms and living rooms are set with a temperature range of 18 to 22; Toilets, foyers, and corridors are set with a temperature range of 18 to 20.

It should be noted that the higher the temperature set, the greater the energy consumption, generally if the floor heating temperature is set above 25, the energy consumption will increase by about 20% to 50% compared with 21.

The temperature of underfloor heating is between 18 and 24 degrees Celsius.

Floor heating uses the whole ground as a radiator, through the heat medium in the floor radiation layer, evenly heats the whole ground, and heats the room through the ground in the form of radiation and convection heat transfer to achieve the purpose of comfortable heating. According to different heat transfer media, it is divided into two categories: water floor heating and electric floor heating, and according to different pavement structures, it is mainly divided into dry floor heating and wet floor heating.

16-24 is most appropriate.

Indoor air quality standard (GB T18883-2002) clearly stipulates: winter heating temperature 16-24, humidity 30%-60%, in line with this standard of indoor temperature is a comfortable indoor temperature.

Heating, ventilation and air conditioning design code for indoor heating design temperature has made clear provisions: when designing heating, the indoor temperature calculated in winter should be determined according to the use of the building, and the main room of the civil building is easy to use 16-24; Auxiliary buildings and auxiliary rooms are heated in 25 bathrooms, 25 dressing rooms, and 18 offices and lounges.

The daily indoor temperature should be controlled at 18 to 22 degrees Celsius. If the indoor temperature is too high for a long time, it will affect the person's body temperature regulation function, causing the body temperature to rise, vasodilation, heart rate acceleration, making people feel fatigue, dizziness, and sluggish thinking. If the temperature is too low, the body's metabolic function will decrease, the pulse will slow down, and the subcutaneous blood vessels will constrict.

The elderly are more susceptible to insufficient blood supply to the heart, while children and pregnant women are more susceptible to colds and flu.

23 27 is advisable. The human body feels most comfortable at this temperature, but be careful to drink plenty of water and avoid drying out and getting hot.

The heating temperature of underfloor heating is generally between 18 and 24 degrees, which is the most suitable temperature for the human body.

<> "The use of floor heating is very convenient, but special attention should be paid to the choice of floor heating, especially the thickness of floor heating, which affects the normal use in the future. So what is the thickness of the underfloor heating.

First, the thickness of floor heating is more and less jujube

The thickness of the general underfloor heating is 5-6 cm. The insulation layer contains about 2 centimeters, the pipeline functional layer is about centimeters, and the bean stone sand is filled with imitation old slurry and cement mortar about 2 centimeters.

Of course, the thickness of the underfloor heating should also be determined according to the way it is laid and the material of the floor. For example, for solid wood floors, the thickness of underfloor heating should be 8-10 cm. If tiles are laid, the thickness of the underfloor heating should not be less than 8 cm.

In addition, the thickness of electric underfloor heating is 4 cm, and the thickness of water underfloor heating is 8 cm.

Second, what problems need to be considered for floor heating laying

1. When laying floor heating, we must pay attention to the warmth of the supervisor, if the supervisor does not do a good job of insulation, it is likely to have a serious impact on the heating of the floor heating.

2. When laying floor heating, the main pipe of floor heating must be flattened. Pay attention to the horizontal when it is horizontal, and vertical when it is vertical, so as not to affect the placement of the tiles behind.

3. When laying floor heating, please pay attention to the use of special flooring materials, because this kind of floor will not release formaldehyde at high temperatures, and ordinary floors cannot control the release of formaldehyde, which may cause damage to human health.

4. When laying floor heating, the design of the supervisor must be appropriate. It is better to ask an experienced person to design it, because the supervisor is equivalent to the heart of underfloor heating. Once it is not well controlled, it is likely to affect our normal use in the future.

5. It must be noted that there can be no error in the position of floor heating installation, and it must be accurate to avoid affecting the subsequent floor heating operation route.

6. When we install floor heating, fix the main pipe with a special clamp with the main pipe, which must be firm. After the floor heating is installed, it is important to carry out a pressure test.

According to the "National Residential Design Code", the floor height of ordinary residential buildings should not be higher than meters, and the indoor net height of bedrooms and living rooms should not be less than meters. Meters are the height between the ground of this floor and the ground of the previous floor, and this size includes the thickness of the floor slab.

The height of ordinary residential buildings is meters, which can save energy to the greatest extent on the basis of ensuring living comfort.

Wherein, indoor clear height =

Floor height - the thickness of the floor slab. The thickness of the floor slab is generally 12-15cm. That is, the net floor height of the general residence is about .

In the decoration, there are suspended ceilings, air conditioning, fresh air, sewer pipes, floors, floor heating, etc.

Among them, the floor heating occupies a height of 0-5cm.

0cm floor heating is divided into dry and wet floor heating, and generally dry floor heating occupies less floor height, see Further Reading for specific comparison. One of the ways to install the floor is to install it with a keel. This "keel underfloor heating" is to install pipes and insulation between the keels.

Making full use of the keel space is equivalent to not occupying the floor heating of the floor height.

Brief analysis. Advantages: does not occupy the height of the floor, heats up quickly.

Disadvantages: the technology is not mature enough, the installation requirements are high, and the ** is expensive.

There is also a kind of underfloor heating, which is to groove the bottom of the wooden floor into the heating cable and then seal it with a layer of foam.

Absolutely does not occupy the height of the floor, and heats up quickly. But.

Poor heat preservation, long-term use or floor deformation and discoloration problems.

2-4cm general dry floor heating does not need to be backfilled, and the floor heating occupies the height of the layer even if the overall thickness of the insulation layer. At present, the dry floor heating on the market mostly adopts modular installation.

Modular wet floor heating, using modules to replace extruded plastic panels, reflective films, nails, and aluminum foil tapes in traditional water floor heating.

Brief analysis. Advantages: does not destroy the insulation layer, standardizes the installation, lifts and protects the pipeline.

Disadvantages: **Expensive, a wide variety of difficult to distinguish between good and bad.

The height of the 5cm traditional water floor heating layer is generally 5cm, insulation board + coil + backfill layer.

Brief analysis. Advantages: mature technology, cheap, many floor heating companies.

Disadvantages: The occupied layer is high, and the nail destroys the insulation layer.

In general, the modular floor heating installation method introduced in Europe is a solution that does not rely on people to do a good job of construction. Subvert the traditional "three-part material seven-point installation" to "seven-point material three-point installation".

However, now there are many kinds of modules in China, and it is difficult for ordinary warm friends to distinguish between good and bad.

The easiest way to tell the difference is that modules without insulation are fooling people! Due to production efficiency and dosage, it is still more expensive than traditional water floor heating. end
