Installation and after-sale service:
Heating installation focuses on installation, the principle is: professional, skilled and secure. To the sales, installation, after-sales service integration of the store to buy more worry and confidence.
4 The warmth of a house depends mainly on the insulation of the walls, windows, roof and ground. There are two main practices for wall insulation in a house: external insulation and internal insulation.
External wall insulation refers to the construction of insulation layers on the external surfaces of vertical external walls. The external wall is the base of the external thermal insulation wall. It is built of masonry or concrete, must meet the requirements of the mechanical stability of the building, can withstand vertical loads, wind loads, and can withstand impact and ensure safe use. It should also be covered. The insulation layer and decoration layer are firm.
After the external insulation is performed, the internal solid wall is a large heat storage body, so that the interior can store more heat, so that “free heat†is generated by factors such as solar radiant heat, human body heat dissipation, household appliances and cooking heat dissipation. "Used better, is conducive to energy conservation.
At present, some energy-saving building walls use internal insulation, and the basic practice of internal insulation is to make insulation layers in solid walls, and in the relatively soft insulation layer, then cover a layer of plasterboard, other plates or do The upper surface is plastered to form a hard surface layer, and the inner insulation layer heats up faster than the outer insulation due to changes in heat storage properties.
In general, the internal insulation is affected by the indoor ceiling, wall structure, etc., and needs to be disconnected at multiple points, and may be damaged by the decoration. The effect is inferior to the external insulation. Although the effect of external insulation is good, but the insulation material requirements are harsh, unless the developer sacrifices the interests of high-quality materials, it will inevitably appear external insulation cracking, the formation of cold bridges and water seepage and other similar problems.
If you buy a house with external wall insulation, especially external wall insulation, it is the first step to energy-saving buildings. When selecting the radiator, the heat load calculation can be reduced by 30% correspondingly, ie from 80W/m2 to 50W/m2. The second-step energy-saving building, the square heat index fell to 40W/m2.
Steel radiators:
Steel products are attractive in shape and have good heat dissipation. Among several varieties, steel radiators are diverse in shape, attractive in appearance, and steel plate radiators that dissipate heat in a convective manner, allowing the room to heat up more quickly and evenly. Prices have also fallen from the previous year. In the home building materials center, people only need to spend 2,000 yuan to meet the needs of 100 square meters of the house. There are many brands of steel radiators on the market, and the quality and price are very different. Relatively speaking, the quality of famous brand products will be stable. It should be noted that steel radiators are prone to oxidative corrosion and are not suitable for use in geothermal water heating and require full water maintenance during non-heating seasons.
Copper and aluminum composite radiator:
Copper-aluminum composite products have good corrosion resistance. The radiators are resistant to corrosion and have a wide range of applications. However, some products do not undergo compounding of two materials. Copper tubes are only added to aluminum products. Experts recommend purchasing brand products with relative quality assurance. In addition, copper-aluminum composite radiator "thin high flat" type of radiator although space-saving, but because of higher radiators require larger water pressure, household heating boiler is difficult to meet the requirements, therefore, household heating It is best not to choose a radiator of this type.
How to choose a radiator how to choose a radiator? How to choose a radiator for home decoration, and how to choose the radiator heating system. If the family is a central heating, choose the horizontal radiator should be installed under the window to block the intrusion of air-conditioning, if you choose to install the vertical radiator should be installed on both sides of the window, because the radiator close to the ground, can make all indoor The air convects, so it maintains an equilibrium at room temperature. How to choose radiator for gas boiler system and non-pressure system, no pressure coal-fired heating system should choose radiator height should not exceed 1500, it is best to about 600 high radiator is the best, so that water flow fast, radiator Good heat dissipation. The height of the gas-fired boiler system should not exceed 1800. If the water temperature is high, you can consider radiators with small water content. If the water temperature is lower than 60 degrees, you must use steel, so that as long as there is water temperature, heat can be dissipated.
The radiator is not hot The radiator is not hot, it may be one of the following reasons: 1. There are less radiators designed or installed, and the total heat dissipation is not enough; 2. The temperature of the heat medium is low, and the heat dissipation is small. Common standard heat dissipation refers to inlet water temperature of 95°C, outlet water temperature of 70°C, and room temperature of 18°C. If inlet water temperature is 70°C, outlet water temperature is 55°C, and room temperature is 18°C, the heat dissipation is about 40% lower; 3. There is a heating cover, often reducing the heat dissipation of about 20%; 4. Intake and outflow of different ways to take over, but also reduce the amount of heat, it is best to go up and down, out of different measurements into the next, the radiator is about 20% lower; 5. Gas blocking, can open the air-conditioning valve to exhaust the air inside the radiator and then close it; 6. Partial blockage in the radiator; 7. Large resistance, in the parallel system, the private exchange radiator may occur this problem, resistance, hot water flow Small, heat dissipation is reduced; 8. Water pressure is low, at the remote or high point of the parallel system, the water pressure is low, hot water is insufficient, and the heat dissipation is low; 9. Door and window ventilation.
Heating households should note that the valves on the heating pipes cannot be switched on and off. When the heating system first moves, it usually requires debugging. Specific to each household is to adjust the valve of each standpipe to a suitable location, open the manual bleed valve of each radiator, discharge the air contained in the radiator, or open the air collection tank installed on the top of the system. The exhaust valve vents until each radiator is warmed up and commissioning is complete. Once commissioning is complete, the valve should be fixed and cannot be switched on and off.
Keep a certain amount of space for heat dissipation in the room near the radiator. Do not stack debris on the radiator or in front of the radiator. Otherwise it will affect the cooling effect of the radiator.
Radiator can not be arbitrarily changed position. The installation of the radiators is arranged in a position conducive to indoor heating, which can ensure that the air convection and the indoor temperature are relatively even, and once the position is changed, the indoor temperature will be unbalanced. On the other hand, once pipelines and radiators are moved, it is very easy to leak and cause unnecessary losses in the home. Do not discharge water from the system at will. If there is a shortage of hot water in the pipeline, cold water must be added to maintain a certain pressure in the pipe network system. The more water lost, the water temperature in the pipe network will drop rapidly, causing the indoor temperature to decrease. A friend who uses steel heating should pay attention to shutting off the valve in time when the heater is stopped. It is filled with water in the heating system, which can extend the useful life. Conditional copper-aluminum composite can also be used for full water maintenance!
