Floor heating is the abbreviation of radiant floor heating. The English name is Radiant Floor Heating. It uses the entire floor as a radiator, and evenly heats the entire floor through the heat medium in the floor radiation layer. The law of using the ground's own heat storage and heat to radiate upwards is as follows Conduct the supremacy to achieve the purpose of heating. It is divided into two categories: water floor heating and electric floor heating from the heat medium, and two types of wet floor heating and dry floor heating from the pavement structure. The dry floor heating does not require bean stone backfill (belonging to ultra-thin type); from the surface decoration Material is divided into floor-type floor heating and floor tile-type floor heating; functionally divided into ordinary floor heating and far infrared floor heating. So, what is the price of installing floor heating ? What are the factors that affect the price of floor heating installation? To install a floor heating, of course, you need to have a certain understanding of its installation price. Next, let's take a look at the price of installed floor heating and the factors that affect the price of floor heating installation. Advantages of floor heating Comfortable health: floor heating is by far the most comfortable way of heating. The indoor surface temperature is uniform, and the room temperature gradually decreases from bottom to top, giving people the comfort of warm feet and feet. "Fitness theory; In addition, because the floor heating heating hot air naturally rises, without air agitation, it is not easy to cause dirty air convection, indoor air is clean, sanitary and clean. Energy saving saves operating costs: the radiant heating method of floor heating has higher thermal efficiency than convection heating, and the heat is concentrated within the height of human benefit; the heat loss during transmission is small, saving about 20% compared with other heating equipment, which saves operating costs20 %. Low-temperature ground radiant heating can be controlled by households and rooms, users can adjust according to the situation, further effectively save energy and reduce costs. Reduce floor noise: At present, prefabricated panels or cast-in-place slabs are generally used in China. The sound insulation effect is extremely poor. People walking upstairs will affect the downstairs. The use of floor heating increases the insulation layer, which has very good sound insulation effect. Floor The heating process was silent. Good thermal stability: Is the floor warm? The ground floor and concrete floor have a strong heat storage capacity. Under the condition of gap heating, the indoor temperature changes slowly, and it feels natural, and there will be no problems due to excessive temperature rise. comfortability. No space occupation and long service life: Underfloor heating is a concealed project, without radiators and branch pipes occupying space, which indirectly increases the area of ​​the living room, which is convenient for decoration and furniture layout; underfloor heating, plastic pipes are buried in the module or concrete layer below the floor , No corrosion, no scaling, if there is no human damage, the service life is synchronized with the building. Disadvantages of floor heating 1. The floor heating system needs to occupy a floor height of 5-6 cm (different insulation materials, floor heating pipes, different construction schemes and methods, and different effects on the floor height), which has a greater impact on the lower floor height housing. 2. Underfloor heating has poor maintainability. Floor heating is a hidden project, which is not easy to maintain. When decorating, choose materials that are resistant to pressure, temperature, corrosion, and thermal stability. It is not convenient for secondary decoration because the pipeline is laid underground and the ground is renovated. At times, it is easy to damage underground pipelines. 3. Underfloor heating is low-temperature heating and requires large-area heating of floor cement and surface materials. Compared with traditional heat sinks, the heating rate of the system is slower when the system is first started, and it needs to be turned on for a long time. Therefore, underfloor heating is more suitable for families with long-term people at home user. Floor heating installation method 1. Preparation Before installing geothermal heat, some preparations are required, such as material configuration, and material selection and configuration according to professional design schemes. For example, geothermal pipes are divided into (PE-ER polyethylene), (PB polybutylene) (PEX cross-linked polyethylene). For example, centralized heating can choose high temperature resistant PB pipe, independent heating is suitable for PERT oxygen barrier, etc., the water separator can choose the intelligent type. Secondly, don't neglect the extruded plastic plates below the ground. Polystyrene extruded plastic plates should be used as the heat-insulating plates. It must meet the following requirements: 1. The density should not be less than 20kg / m. 2. The thermal conductivity should not be greater than O.05W / (mK). 3. The compressive stress should not be less than 100 kPa. Second, the basic construction process Scheme design → material entry → fixed installation of water separator → connection of main pipe → laying of thermal insulation layer, reflective film → floor heating coil → connection of water separator → laying of buried pipe according to construction drawing → setting of corner expansion joints → intermediate acceptance ( Floor heating coil compression) → bean stone backfill construction after qualified → backfilling is completed (secondary pressure test) → overall system commissioning and operation. The above basic geothermal installation methods may be different in the construction process of some companies, but they are inseparable from each other, and the construction guidelines for the floor heating are the same. 1. Fixed installation and connection of the main pipeline of the floor heating. 2. The fixed installation of the floor heating sub-collector. 3. Laying of insulation layer of floor heating insulation board. 4. Floor heating coil construction. 5. Floor heating compression test. Precautions for floor heating installation 1. Independent heating users must consider the installation of the flue before installing the gas-fired wall-hung boiler for easy maintenance in the future, and try to avoid adding extension pipes. 2. Before the installation of the floor heating, the hydropower transformation workers should walk along the corner of the wall or carry out slotting on the ground. 3. The geothermal installation should be waterproof before installation. 4. The water divider is generally installed in the bathroom or kitchen. 5. It is not recommended to lay a floor heating system under legless homes. 6. In the subsequent decoration process after the floor heating installation is completed, the owner should remind the decoration company to do a good job in the protection of finished products. Install floor heating price The installation cost of the water heating villa: The investment in water heating is relatively high. For large-sized houses, the required boiler configuration is high, and the overall price is more expensive. The price of installing water and floor heating for a house of 300 square meters is about 50,000 yuan. However, since its service life can reach several decades, it is still very cost-effective. For rooms with a heating area of ​​about 300 square meters, if you choose water heating equipment, including pipes and boilers, the initial cost is between 40,000 and 50,000 yuan. In use, the monthly natural gas cost is about 2,000 yuan / month. Electric floor heating villa installation cost: the price of electric floor heating ranges from 280 yuan to 400 yuan per square meter, the electric fee per square meter is about 30 yuan per month, the same 300 square meters room, 8-10 hours per day, monthly electricity fee The expenditure is also about 2,500 yuan. This is not a small expenditure for an ordinary family. That is to say, a house of 300 square meters, if you want to install electric floor heating, the entire cost is about 40,000 to 60,000. Factors affecting the installation price of floor heating 1. Floor heating pipe: The price of floor heating pipe varies greatly, and the quotation is different in each region. The installation price of domestic floor heating pipes is about 70 yuan per square meter. If it is imported floor heating pipes, the price may be around 100 yuan. There are many inferior pipes in the market. The price is cheap but it is not recommended to buy. 2. Wall-hung boiler: The gas-fired boiler is the heat source of floor heating, which can heat and provide domestic hot water. Different brands and different models of boilers offer different prices. Due to the higher technical content, the price of imported boilers is generally higher than that of domestic ones. Generally, one boiler is about 10,000 yuan. Good brands of imported boilers include Bosch and Weineng. 3. Thermostat: If users need to increase the intelligent temperature control function, then the choice of the sub-catchment should also change accordingly, because many domestic water separators do not support temperature control, so before calculating the floor heating price, the user must first Make clear what kind of configuration and pipes you need at home, and finally the overall price of the floor heating, and then accurately design according to your configuration and house plan. 4. Auxiliary materials: Insulation board, reflective film, electric heating valve, staples, etc. are all underfloor heating auxiliary materials, and all have a great relationship with the floor heating installation cost. Good quality prices will definitely be more expensive. Generally, the installation company will have supporting auxiliary materials For users to choose. 5. Labor cost: Labor cost is also a part of the floor heating installation cost. If the price is too high, it is likely to be stupid. If the price is too low, it may be cut corners during installation, and the hidden dangers of later use will increase. Therefore, users need to choose regular professional and word-of-mouth floor heating. Company to install.
