At the peak of the renovation of the house, many owners called to ask if they could change the heating method during the decoration. For example, the central heating or household heating was changed into floor heating, which not only was comfortable and beautiful, but also made the decoration more convenient. However, experts say that central heating and floor heating systems have their own advantages and disadvantages. If a centralized heating system has been adopted, it is best not to change the heating method easily.
Central heating, environmental protection and safety
According to Fan Wei, a senior engineer of the Second Architectural Design and Research Institute of Beijing, there are two main types of heating systems for residential buildings, central heating systems and household heating systems. Centralized heating, that is, a concentrated heat source, transfers heat to the user through the pipeline. At present, the central heating in the Beijing market is mainly boiler and urban heating network heating, and household heating includes wall-hung boiler heating and electric heating.
Although central heating has unfavorable factors such as heat loss in pipe network, energy consumption in pipeline transportation, high initial construction cost, and uneven heating and cooling due to construction or operation management level, Fan Yu believes that Compared with household heating, central heating is a relatively economical, energy-saving, safe and environmentally friendly heating system. Because there is a person responsible for operation management, the central heating operation is highly efficient and has an automatic monitoring system. It is regularly inspected and maintained every year, and the safety performance is relatively high. From the environmental protection point, the environmental pollution caused by smoke exhaustion can be treated centrally, compared to each household. Smoke is much more environmentally friendly.
However, natural gas pipelines and urban heat networks do not cover the whole city. In some places, household heating is also required. On the Other hand, the central heating needs to build a boiler room, which not only needs to occupy a certain land area, but also has a safe distance requirement from the surrounding buildings, which has an impact on the layout of the entire community. For economic considerations, some developers will choose small-sized boilers for heating. Compared with central heating, the household heating is flexible, the use time is controlled by the owner himself, and the household consumption can be measured according to the actual consumption of the owner; in addition, the boiler room and the outdoor pipeline can be omitted.
In addition, the household heating costs are related to the conditions of occupancy and the environment. If there are only a few owners in the whole building, or if there is no heating in the neighbors, the heat will flow to the Quartet and the heat consumption will be large. In addition, the ordinary household-type wall-hung boiler has a short service life and high maintenance and depreciation costs.
The floor is warm and comfortable but there are many precautions
Floor heating is divided into two types: electric heating and plumbing. Most of the floor heating currently used is plumbing, that is, the water pipes are laid under the ground, and the hot water is transferred to the room through radiation and convection. Because the heat is transmitted from the bottom to the top, it meets people's physiological needs and feels comfortable. Because people feel the temperature of the floor heating environment is 1~2 °C higher than the actual temperature, it is more energy-efficient than other heating methods. Since the pipes are all laid under the ground, the layout of the owner's home is not limited.
But the heating effect of the floor heating is not perfect in the imagination. Since the heat is mainly transmitted by radiation, the blockage of the furniture affects the heat dissipation effect. In addition, in the north-facing bedroom and bathroom, because the required amount of heat is relatively large, and the bed, wardrobe and table are removed from the bedroom, the remaining floor space is small, because the floor heating temperature is not high, the required heating is slightly more. .
Floor heating has certain restrictions on water temperature. It is necessary to set the outlet temperature of the wall-hung boiler. The lower return water temperature of the floor heating may affect the service life of the ordinary wall-hung boiler and increase the maintenance cost. Due to structural reasons, it is best to use laminate flooring or floor tiles when using floor heating. The heat conduction effect is good, and solid wood flooring or composite flooring may cause cracking. The carpet will increase the thermal resistance and affect the heating effect, so you can't use the carpet. In addition, it is best to choose legged furniture to reduce thermal resistance.
Concentrated heating to change the floor heating must be cautious
Experts said that if you are doing floor heating, you need to add insulation layer of not less than 2 cm thick on the floor, and then lay a pipe layer of about 5 cm high, and then level the floor or floor tiles. In this way, if the floor heating is 4-5 cm higher than the ground level of the ordinary floor, the room height will be reduced, and the floor height may also affect the opening of the door.
Fan Wei said that if this is the household wall-mounted heating, as long as it can accept the floor heating is higher than the original, there may be steps at the entrance, and the original door is modified to have the basic conditions for changing to floor heating. However, if it is central heating, it is necessary to be careful to change to floor heating. Because the original central heating system was designed and constructed by professionals, it is possible to share a heating water system in each building in the entire area and to conduct a comprehensive water pressure test before use. If you want to change to floor heating, you need to re-lay the pipe. Since there may not be the original construction drawings and there is no strong professionalism, it is difficult to ensure that the water pipe docking does not cause problems. Once the water leaks, the consequences are unimaginable. “It can be changed under the guidance of property personnel, but it is easy to move.â€
He also said that the heating method is planned and designed by professionals in the construction. It must be justified. The owner should not easily change because of aesthetics or other reasons.
