Radiator has a lot of material to choose from, but in the past, every household is mainly the kind of bulky cast iron radiator. But cast iron radiator also has many advantages, such as corrosion resistance, long life, cheap price. But because of the single backward style, energy consumption is higher than the new radiator, and now the house central heating is not suitable for cast iron radiator, so unless it is some old houses, otherwise it is not able to use cast iron radiator.
Cast iron radiator how much a group of household
The price of cast iron radiator is usually between 30-50 yuan/piece, if it is a brand of cast iron radiator the price will be higher, in 60~70 yuan/piece. But compared with other materials, the price is very affordable. However, the specific single column radiator how much money depends on the specifications of the radiator, such as its height or heat dissipation area.
If you want to know the price of a group of cast iron radiators in the home, then you need to calculate the number of a group of needed radiators through the room heating area and single column radiator area, and then multiply the price of a single column radiator, get the cost of buying a group of cast iron radiators. If it is installed, but also pay the corresponding pipe and other costs, as well as installation fees.
How about a household cast iron radiator
Cast iron radiators are suitable for closed or open heating systems. The main features are safety and durability, and the corrosion rate is slower than low carbon steel radiators, aluminum alloy radiators and water tank radiators. Because its corrosion state is needle corrosion, rather than block corrosion, so the rust is not easy to fall off, oxygen can not invade a large area of the inner body and cause deep corrosion, so the service life is about 25 to 30 years. In addition, cast iron radiators are the least expensive of all types of radiators and are very economical to use.
But at the same time, its material is very heavy, the shape is single, the style cannot match the modern decoration style, the heat price is low, and it is not easy to clean. Moreover, the inner cavity of the cast iron radiator sand is easy to damage the temperature control device, the production of energy consumption is relatively high, energy saving and new products can not be compared. So very few users are using it now.
Cast iron radiator maintenance method
1. If some cast iron radiators are not hot, use an exhaust valve to release air. When the water overflows, close the bleed valve;
2. Do not use utensils and organic solvents that will damage the sprayed surface. Use soapy water and other mild cleaners; Finally, take care to prevent other objects from hitting or scratching the cast iron radiator. If scratches appear, they should be repaired in time with the same color of paint to avoid large-scale disassembly and rust.
3. Perform adequate water maintenance during non-heating periods. The inlet and return valves of the cast iron radiators must be closed 1-2 days before stopping heating to ensure that the cast iron radiators are filled with water. If water is released during the non-heating season, the residual water in the inner cavity of the cast iron radiator should be retained. This, combined with high temperature and oxygen enrichment, will accelerate the oxidation of the cast iron radiator, resulting in waterline corrosion and corrosion formation.
