How to clean cast iron radiators? How to remove rust from cast iron radiators

Close the return valve. Before cleaning, in order to ensure safety, be sure to turn off all the return valves, and then use a wrench to gently unscrew the plug on one side of the radiator by hand. Here is a warm reminder for everyone:

When the plug is gently unscrewed by hand, some water will flow out of the radiator, and you can use the water in the basin to rinse it accordingly.

Rinse the radiators. When opening a temperature control valve, the relevant flushing is carried out until the water flowing out of the radiator is relatively clear, and the temperature control valve can be closed once the water flowing out is relatively clear. The same measures are taken to clean the radiators accordingly, after which the valves for the water inlet are opened and the relevant exhaust is carried out.

Different radiators have different cleaning methods, and different cleaning methods are used for different styles of radiators.

a. The steel column radiator is easy to clean, and the surface can be as bright as new by wiping it with an ordinary towel.

b. The space between the two adjacent columns is small, and you can use the "feather duster" of chemical fiber, which is elastic and long enough to wipe the heating gap, and the duster can also ensure that the dust does not fly after being wet. As long as you stretch the water-dipped duster into every interval, pull it back and forth like a saw, and rinse the duster with water in time, and the heating will be clean in a while.

c. The gap of the copper-aluminum composite radiator is small, and you can use a discarded ** wire or other thin rope with a slight hardness, tie a wet rag at one end, and pass through the hole of the radiator at the other end. Then while shaking the rope, slowly pull the rag and repeat a few times to clean the radiator.

The radiators at home are seriously scaled, and a professional descaling company has appeared, and you can contact them to help clean themBoth pipes and radiators need a clean environment. The radiator uses hard water, and the inside is mostly carbonate and other substances, which can be connected to an external water pump, and it is easy to add dilute hydrochloric acid to the radiator, add a small amount of hot water, let the pump work to circulate the dilute hydrochloric acid inside, dissolve the impurities inside the radiator, release the sewage after cleaning, and then clean it with clean water.

Antiscalants are made up of alkaline substances and organic and inorganic substances. The alkaline substance in the antiscalant causes the calcium and magnesium salts in the boiler water to form water slag, which is removed by draining.

In this way, calcium and magnesium ions are removed, making it not form a hard scale. The organic matter in the antiscalant will increase the fluidity of the slag and make it easy to discharge, and at the same time, the organic matter will also form a barrier layer on the metal surface, preventing the formation of scale on the metal surface. This series of chemical and physical actions prevents the formation of scale.

Adding the antiscalant to the running boiler water, it will protect the whole system, including the radiator, the biggest advantage of this method is that the customer does not have to do it himself, it is carried out by the community or the heating company, and many heating systems currently use this method, and the effect is good.

Precautions for radiator cleaning.

1. Before cleaning, in order to ensure safety, be sure to turn off all the return valves.

2. Before the heating system is officially put into operation, the heating company has added anti-scale chemicals to the heating system to avoid scaling. Therefore, users cannot put the water in the radiator privately, which contains chemical components.

3. If the temperature of the radiator at home drops or there is an abnormal sound in the radiator, it is recommended that the user can find a professional to flush the inside of the radiator to avoid the problem of water leakage caused by the heating when cleaning by himself.

Clever cleaning of radiators can provide a clean, clean, and comfortable warm environment. Warmly remind everyone that in order to avoid accidents, it is best to ask a professional cleaning staff to clean the radiators. When considering installing heating, don't just look at **, after-sales service is also very important, the most important thing is to be steadfast in your heart.

First of all, close all the inlet and return valves, use a wrench to gently unscrew the plug of the radiator, and pay attention to the fact that a basin should be placed under the radiator corresponding to the plug to connect the water flowing out of the flushing radiator (prepare another basin so that the replacement is almost full.)

Then open one of the thermostats (can be opened and closed, the flushing effect is better) to flush the radiator, until the water is clear, close the valve, open the other thermostat and continue to flush until it flows out.

When the water is also clear, close the temperature control valve, tighten the plug, and then open the valve for inlet and return water, and exhaust; For the radiator that goes in and out, the valve is connected with the radiator for flushing; For Meditech.

The steel bathroom radiator in the raw room can unscrew the exhaust valve on the top of the radiator, open the valve and flush it directly, so that the dirty water can flow directly from the bathroom floor drain. Specifically, you can learn more about Comfort 100, I hope it can help you.

The structure of the cast iron radiator is a bundle of structures closely arranged, so it is difficult for the hand to reach into the radiator, and the surface of the radiator is extremely rough, so it is particularly troublesome to clean, the available method is to wipe with a towel, but it is difficult to wipe clean; Or flushing with water will cause flooding of furniture and floors, so cast iron radiators are rarely used in homes now.

1. First of all, use a shovel blade to remove the rusty and cracked places.

2. Then use sandpaper to remove the rust on the surface.

3. Moisten the wool brush with water (to prevent hair loss).

4. Add about 10% water to the water-based radiator paint bucket and stir well.

5. Use the paint sewer liquid to evenly coat the radiator.

6. Finally, a new radiator with a new surface was introduced.

How to clean the inside of an old-fashioned cast iron radiator.

Hello, dear friends, Rarity is the No. 8 teacher on the list who studies home furnishing and decoration, and is good at decoration, home building materials purchase, home matching, etc. We're happy to answer your questions. I'm going to break it down for you.

Dear Da, you bring a good defense, I am a home expert Rarity, I am happy to answer for you, the old-fashioned cast iron radiator cleaning the inside of the way is: close the inlet and return valves first, and gently unscrew the plug of the radiator with a wrench. Note that a basin should be placed under the radiator corresponding to the plug to flush the water flowing out of the radiator (another basin should be prepared in order to replace the basin that is about to be full), and then one of the temperature control valves should be opened (it can be opened and closed suddenly, and the flushing effect is better) to flush the radiator until the water flowing out is clear, close the valve, open another temperature control valve and continue to flush, until the water flowing out is also clear, close the temperature control valve, tighten the plug, and then open the valve for incoming and returning water, and exhaust; For the radiator that goes in and out, the valve is connected with the radiator for flushing; For the steel bathroom radiator in the bathroom, you can unscrew the exhaust valve on the top of the radiator, open the valve and flush it directly, so that the dirty water will flow directly from the bathroom floor drain.

When there is no water supply, you can use a hose to fill the heating with water and rinse it.

After the water is supplied, the rusty water in the heating can be released. Radiator maintenance radiators sit idle until the next heating season. Therefore, it is necessary to clean and protect the radiator before heating.

Proper care of the radiator is also essential.

Before the arrival of the new heating season, the gas release valve, plug and pipe fittings on the pipeline connected to the radiator should be checked, and the threaded connection should be tightened if there is looseness (affected by thermal expansion and cold contraction) to avoid water leakage after heating.

Also, when cleaning the surface of the radiator, please use a soft towel or brush, do not use any kind of organic solution, you can use daily detergents, such as: detergent, weak alkaline soapy water, etc.

There are several types of radiator materials:

1. Cast iron radiator fiber noisy piece, cast iron radiator is a kind of radiator used more in the past, the first advantage is that it has good performance, both corrosion resistance and good thermal conductivity, and the life is relatively long, and the second advantage is that it is very cheap, many families can afford it.

However, the appearance of cast iron radiators is relatively low, and the appearance has not kept up with the pace of the times, and cannot be well integrated into modern home decoration.

2. Copper-aluminum composite radiator, that is, a high-efficiency and energy-saving radiator made of copper tube and aluminum profile through various processes. It mainly adopts the convection heat dissipation method, which has strong thermal conductivity and good heat dissipation, which is a very good choice for radiator materials.

In addition, the copper-aluminum composite radiator has a relatively high appearance and can be seamlessly integrated into a variety of decoration styles. However, the ** of this type of radiator is quite high, and families with insufficient budget may not be suitable.

3. Steel radiator, steel radiator is also a radiator material with a relatively high current usage rate. In terms of appearance, steel radiators have a variety of shapes and a wide range of options. In terms of thermal conductivity and heat dissipation, steel radiators can also be stable enough.

**In terms of aspect, although it is not as cheap as cast iron radiators, it is still much more economical than copper-aluminum composite radiators.
