Brief introduction of floor heating
1, definition: What is floor heating?
It is understood that low-temperature floor radiant heating is to heat the floor to the surface temperature of 18-32℃ through heating pipes, aluminum-plastic composite pipes or conductive pipes buried under the floor, and radiate heat evenly to the room to achieve the heating effect. Compared with the traditional heating method, it can be said that it has the following advantages:
2, the room temperature distribution is uniform
Using heating method, because the whole floor radiates heat evenly, the indoor temperature difference is very small. Moreover, the indoor temperature gradually decreases from bottom to top, and the ground temperature is higher than the temperature of the human respiratory system, giving people a comfortable feeling of warm feet and cool head.
3. It is conducive to creating a healthy indoor environment.
When the radiator is used for heating, the outlet water temperature is generally above 70℃, but when the temperature reaches 80℃, a cloud of dust will be generated, which will cover the wall above the radiator with dust. Floor heating can eliminate the convection between dust and turbid air and give people a fresh, warm and healthy environment.
4. High efficiency and energy saving
Because of the large heating radiation area, the relatively required water supply temperature is low, only 40 ~ 50℃. But also can overcome the defect that part of the heat of the traditional heating sheet is lost from the window, which affects the heating effect.
Step 5 save space
Because the heating pipes are all laid under the floor, the space for placing radiators is saved, which is convenient for indoor decoration and furniture placement.
Another method of floor heating is called "water flowing solid wood composite floor". After years of scientific research, Liaoning Jiarongyao Trading Co., Ltd. finally developed a "solid wood composite water floor" which integrates heating, refrigeration and decoration. Approved by the State Patent Office, it has obtained three invention patents and three utility model patents. This product has the advantages of energy saving, environmental protection, comfort and durability, easy disassembly and assembly, and easy change of floor color.
Because the product adopts new materials, new technologies and new processes, and circulates cold and hot water in the hollow inner layer of the floor, it has the characteristics of one-way heat dissipation and small thermal resistance, so it can release the collected heat to the maximum extent, and then achieve the best energy-saving effect. In order to achieve both thermal conductivity and good thermal insulation of solid wood composite floor, imported polymer PEX is used as raw material for floor water pipes, and corresponding accessories are added to enhance the corrosion resistance and aging resistance of the floor. This product contains no harmful substances, and has the characteristics of ultra-low temperature heating (the water temperature is only between 28℃ and 45℃), energy saving, environmental protection, flame retardant, high heating efficiency and long service life. In order to ensure its tightness, hot melt sealing is adopted to ensure the floor tightness to the greatest extent.
Floor heating system is the most popular and advocated heating mode in the world at present, and it is the most comfortable in terms of energy saving, material saving, land saving and space saving. At present, the floor heating system has been widely accepted and recognized in Europe, North America and East Asia. With the continuous improvement of people's living standards in China, more and more people know and accept the way of floor heating.
Second, the advantages of geothermal heating
Compared with the traditional heating method, it can be said that it has the following advantages:
1, the room temperature distribution is evenly heated, because the whole floor is evenly radiated, so the indoor temperature difference is extremely small. Moreover, the indoor temperature gradually decreases from bottom to top, and the ground temperature is higher than the temperature of the human respiratory system, giving people a comfortable feeling of warm feet and cool head.
2, conducive to creating a healthy indoor environment, using heat sinks for heating.
3, large heating radiation area, high efficiency and energy saving.
4. Save space.
5. Diversification of energy forms. The circulating hot water needed in the floor heating system can be heated by any energy source, such as traditional gas-fired boilers and heat pump units, or by renewable energy sources, such as ground source heat pumps and solar energy.
Third, the characteristics of geothermal heating products
Function 1: energy saving
The energy-saving aspect of solid wood composite flooring is reflected in the real low-temperature operation, and the water temperature only needs to be between 28℃ and 45℃. The difference between water temperature and ground temperature is only about 5℃. In terms of radiant heating, this product is faster and more direct than ordinary geothermal, and has better energy-saving effect. Each room can control the temperature separately and regularly. In order to realize intelligent energy saving, a telephone remote control system can be installed, which is suitable for people who go out for a long time and have no fixed schedule. Under normal circumstances, it takes about 8- 10 minutes to reach the specified standard heating temperature. This product is not limited by heat sources, and can be used in air conditioners, gas stoves, induction cookers, air source heat pumps, water source heat pumps, ground source heat pumps, solar hot water heating projects, central heating, etc. As a heat source. The energy-saving effect is remarkable, and compared with other heating methods, the heating cost can be saved by about 30_-50_ _.
Feature 2: Environmental protection
The products have been tested by national authoritative organizations and meet the general requirements of "building a conservation-oriented society (four festivals and one guarantee)". New technologies and new processes are adopted in production to make the products meet the requirements of green products. When installing the floor, the environmentally-friendly and flame-retardant extruded benzene board is used as the cushion, which makes the floor have the effects of sound insulation and heat preservation, makes the feet feel more comfortable, releases heat energy to the maximum extent and reduces noise interference between floors.
Feature 3: Unique design, high grade and permanent durability.
The solid wood composite water floor adopts new technology and new process, which has the characteristics of no cracking when dry, no bulging when wet, no corrosion, no moth-eaten and no ridging. The total thickness is only 35mm, which not only saves building materials, but also saves the height of home decoration space, making your decoration effect more perfect. The floor is detachable and can be moved and installed for permanent use. The stability of the floor is reliable. Tested by relevant departments and experts, the service life is as long as 50 years, the bearing capacity is 20 tons/meter, the wear resistance is more than 8500 revolutions, and it is flame retardant and resistant to ultraviolet radiation. A single family can control the temperature independently, but also can control it centrally, which is convenient for customers to choose according to their needs. This product brings together the "essence" of previous floor heating decoration, improves the shortcomings of various floor heating decoration, transforms a single floor heating decoration into functional decoration, rewrites a new chapter in the history of heating, and is a great pioneering work of human heating decoration!

Verb (abbreviation of verb) Comparison between geothermal energy and geothermal energy
Geothermal structure consists of coiled water pipes and cement. Coil spacing 150mm-250mm, and the covering height of cement surface above 50mm is 80 mm- 100 mm ... Disadvantages of this structure:
1. Reduce the height of the house space
2. Increasing the overall weight of the building directly affects the seismic capacity of the building, while the total weight of the water floor is only 5 kg per square meter and the total thickness is only 35 mm If this product is used in the whole building, the story height can be reduced and the load of the building can be reduced.
3. The heat dissipation is not concentrated, and a large amount of heat is conducted to the surrounding walls downstairs, resulting in large heat loss and slow indoor temperature rise. At the same time, cement will emit harmful gases at high temperature, which is harmful to human health. The permeable floor does not have the above shortcomings and refuses dust pollution. Almost 90% of the heat of the permeable floor is uploaded indoors, and the benzene board laid under the floor not only keeps warm, but also plays the role of silence and shock prevention.
4. Maintenance difficulty: once a leak occurs, it is difficult to find and it is even more difficult to maintain. If necessary, it is necessary to redo geothermal energy, which is labor-consuming, time-consuming and material-consuming, and brings great trouble to customers.
In addition, the construction of coil geothermal is very large, so it must be carried out under the condition of high ambient temperature in winter, otherwise the cement will be loose, and the water floor will be assembled, which saves the cost of repaving the floor, is convenient for installation and construction, is not limited by seasons, and will never produce scale.
Energy-saving comparison of several connecting heat sources with intransitive verbs
1, pipe network connection: using pipe network heat source to connect with this layer, there are several points to be explained.
(1) The pollution in the pipe network cannot directly pass through this product, because the water in the pipe network contains a lot of rust, which is easy to block the connecting pipes and water pipes.
(2) A heat exchanger must be used to keep the circulating water of the floor system clean.
(3) Eliminate the hidden danger of water leakage in high-pressure pipe network.
(4) Because the open water tank also increases the indoor temperature in winter and eliminates dryness, under the same conditions, the indoor temperature with this floor is 8- 10℃ higher than that with other heating methods.
2. Electric heating source: all of them can be directly connected with this product, which is more energy-saving than other electric heating 15% to 30%.
3. Gas heat source: This product can be directly connected with gas water heater, which is more economical than electricity.
4. Solar energy plus distributed heat source: solar energy can make the water temperature reach about 40℃ under the sunshine in winter, which can be used for direct heating.

5. Ground source heat pump: The use of our floor saves secondary heating and greatly saves energy funds.
6. Air conditioning: Refrigeration and heating are more comfortable, healthier and more energy-saving, saving electricity by more than 30%.
This product is warm in winter and cool in summer: there are two ways to cool down in summer: one is physical way, which can directly add ice cubes to the water tank, and the other is mechanical refrigeration, which is more economical by adding refrigeration devices to the auxiliary settings. More comfortable.
Seven, geothermal heating professional research
1. What material is good for floor heating decoration?
People in the decoration industry pay more attention to the wooden floor. In view of the emergence of this new heating method, there have been special sales in the building materials market for this heating method. Manager Cui, a three-dimensional company that distributes Korean floors, said that the selection of geothermal heating should master the following principles: stable size, good thermal stability and low moisture content, so that it is not easy to deform after heating; In order to facilitate heat exchange and conduction, the padding should not be too thick; The size should be thin, not thick, wide and not narrow to meet the requirements of deformation resistance and heat conduction.
2. Pay attention to the installation of geothermal floor.
Compared with the general composite floor, the installation of geothermal floor has relatively strict regulations. If the installation workers are not trained and the laying method is improper, even if they choose special ones, there will be problems of warping and deformation. According to Master Huai of Sanwei Company, before laying geothermal floor, geothermal heating test must be carried out, and the inlet water temperature must reach at least 50℃ to ensure the normal operation of heating. And keep the temperature for more than 24 hours, so that the ground is completely dry. If the geothermal heating test cannot be carried out, the construction will not be carried out in principle, and it is absolutely forbidden to drill holes and hammer nails on the ground with an electric hammer to prevent the heating coil from being damaged. Due to the large tidal volume released by geothermal heating, it is necessary to work hard on moisture-proof treatment in construction.
When the shop is stuck, you should first lay a layer of plastic cloth on the ground to isolate moisture and release it from the skirting board around. Then put on the usual damp-proof pad. Leave enough expansion joints around, and use a skirting board thicker than the current general floor. Moreover, laying the ground and installing the skirting board should be divided into two constructions. 48 hours after laying, after the glue is completely dried, remove the fastener and then make the skirting board. Moreover, heating can only be provided 24 hours after the floor is installed.
In addition, Master Huai also reminded consumers to pay attention when using geothermal floor: as the floor is a heat dissipation surface, try not to make fixed decorative pieces or put legless furniture, so as not to affect the flow of hot air and weaken the warm-keeping effect; When heating up for the first time or when geothermal heating is not turned on for a long time, it should be set at the lowest temperature first, and then slowly heated up, preferably once every hour or so. Before heating, keep the floor clean and dry to prevent cracking and deformation due to excessive heating.
3. How to choose a wooden floor
(1) It is best to choose the wooden floor of a big store, because the supply is sufficient and the quality is reliable.
(2) Some people think that the wider the wooden floor, the better. Actually, it's not. Generally, the wider and longer the wooden floor, the greater the probability of deformation. Our specific standards are: length 1.2m and width 12cm.
(3) The wood grain of the wood floor is also very important. Generally, straight wood grain is the main pattern, with as few patterns as possible, except for customers who like this style. Because the deformation coefficients of patterned wood floors and straight lines are different, if they are laid together, they will have a great influence on each other.
(4) The choice of hardness is also very important. When choosing, you can scratch it with your fingers. If the impression is deep, it means that the quality is not high, and harder wood should be chosen.
(5) Pay attention to the flatness of the floor when selecting, so that the difficulty can be reduced when laying.
(6) Try to choose the floor with small color difference. The floor with large color difference is laid in a hidden place, and the place with small color difference is laid in an obvious place, and the effect is very good.
Eight, silicon crystal floor heating
1, energy saving of silicon floor heating system
Silicon floor heating is made of high quality special materials. Because the resistance value of the product is fixed when it is designed, it will heat up after being electrified. It is said that this product is energy-saving, because the thermal efficiency of this product is very high, which can basically be said to be 100%, which means that almost all the electric energy you supply generates heat energy, so it is very energy-saving. In addition, this product has a positive temperature coefficient, that is, when the temperature reaches the design temperature, the resistance increases and the power decreases, thus saving energy.
2. The operating cost of this system is cheaper than other floor heating systems.
When the silicon crystal electric floor heating system is turned on, the surface temperature can reach the design standard (about 28℃) in 15 minutes, and the room temperature can reach the design standard in about 2 hours (18-20℃). After two hours, you can control the work according to the set time, work 10 minutes, and rest for 20 minutes. According to this calculation, one day (24 hours -2 hours) ×20 minutes =440 minutes. 440 minutes+120 minutes =660 minutes, that is, full-load operation is 1 1 hour. In actual use, you won't open a room without anyone, will you? It's not necessary to drive when no one is around during the day, is it? According to this conservative estimate, the electricity consumption in a day will not exceed 7 hours. If the installed power is 6000 watts according to the construction area 100 square meter (along the river), that is to say, 6 kwh per hour when fully loaded, 1 1 hour 66 kwh, 7 hours 42 kwh. The electricity price (and peak-valley discount) in your area can be calculated more or less conveniently. We calculated that compared with water heating and gas consumption, we should save at least a quarter of the cost.
3. The silicon crystal electrothermal floor heating power supply system is safe.
The heating plate of silicon crystal floor heating adopts polymer insulating material, and the contact part is waterproof, so it can be used even in water.
4, silicon floor heating system energy saving
Silicon floor heating is made of high quality special materials. Because the resistance value of the product is fixed when it is designed, it will heat up after being electrified. It is said that this product is energy-saving, because the thermal efficiency of this product is very high, which can basically be said to be 100%, which means that almost all the electric energy you supply generates heat energy, so it is very energy-saving. In addition, this product has a positive temperature coefficient, that is, when the temperature reaches the design temperature, the resistance increases and the power decreases, thus saving energy.
5. Will there be uneven heat dissipation?
This will not happen, and the heating effect depends on our calculation during installation. If the power supply is equipped accurately, there will be no uneven heat dissipation. Moreover, the silicon crystal electrothermal floor heating system generates heat evenly through surface radiation, and the temperature consistency can be obviously felt above the knee.
6. What is the service life?
All kinds of floor heating products have a fatal weakness, that is, the aging speed is too fast! Moreover, the operation, maintenance and depreciation costs are too high. Silicon crystal electrothermal floor heating system can guarantee the same service life as your building, so the maintenance cost is zero.
7. Advantages of floor heating
① Comfort, sanitation and health care: radiant floor heating is the most comfortable heating method, with uniform indoor surface temperature and gradually decreasing room temperature from bottom to top, giving people a good feeling of warming their feet and cooling their heads; It is not easy to cause polluted air convection and the indoor air is clean; Improve blood circulation and promote metabolism.
② Save space and beautify the living room: the radiator and its branch pipes are cancelled indoors, which increases the usable area and is convenient for decoration and home layout.
(3) Efficient and energy-saving: the radiation heating mode has higher thermal efficiency than the convection heating mode, and the heat is concentrated at the height that the human body benefits; The heat loss during transmission is small; Low-temperature floor radiant heating can be controlled by households and rooms, and users can adjust and control according to the situation, which is effective in saving energy.
(4) Good thermal stability: the ground with warm floor and concrete floor have large thermal storage capacity and good thermal stability. In the case of intermittent heating, the indoor temperature changes slowly.
⑤ Low operating cost: Compared with other heating equipment, it can save energy by 20%, and can make full use of low-temperature hot water resources or use electricity price policy to reduce operating cost.
⑥ Long service life: In low-temperature floor heating, plastic pipes or heating cables are buried underground without scaling, corrosion and man-made damage, and the service life is synchronous with that of buildings. Compared with convection heating, it saves maintenance and replacement costs.
Nine, geothermal heating system
Ordinary air conditioners (including wall-mounted air conditioners and central air conditioners) and radiators are heated by convection. The heating method is to warm the head and cool the feet. Its biggest problem is that it feels dry and uncomfortable, easy to make dust fly, and easy to get air conditioning disease after long-term use. The floor heating system circulates low-temperature hot water through a closed pipe buried under the floor, and achieves the heating effect through far-infrared wave heat transfer. Floor heating is the most comfortable and healthy heating method in the world at present.
Floor heating is mainly composed of heat source, heating floor, heating plastic pipe and temperature control system. The heat source can be various heating wall-hung boilers, heat pumps, solar energy and central heating. Heating floor is divided into wet concrete and dry concrete; PEX, lead, PP-R and PERT pipes can be used to heat plastic pipes. In order to ensure the long-term stability of the whole floor heating system, oxygen isolation pipes must be used. The temperature control system is used to ensure the stability, comfort and energy saving of the system, and consists of a water separator, a water mixing center and a room temperature controller.
