Part1: Instructions for cleaning and maintenance of central heating household heating equipment
It is late March, Many districts with central heating have also stopped heating. I remind you that while enjoying the warmth of spring, you also need to pay attention to the maintenance of heating facilities. Let’s take a look at how to clean and maintain the heating equipment after the heating is turned off.
First, close the heating exhaust valve
There are some impurities and rust, and heating units generally use the intermittent period of stopping heating to add water to the heating pipes to flush. And this kind of flushing is generally not notified to the residents, so once the pressure flushes, people who forget to close the vent valve will leak water in their homes. Therefore, after the heating is stopped, the exhaust valve of the heating pipe needs to be closed tightly.
Second, do not forget to maintain full water
Whether it is a central heating system or a home The independent heating system of the wall-hung boiler, whether it is a steel radiator, a cast iron radiator or a copper-aluminum composite radiator, should be fully maintained with water. Full water maintenance can isolate the oxygen in the radiator and heating pipes, reduce the oxygen content in the water, prevent oxygen corrosion, and prolong the service life of the radiator.
Three, check whether there is water leakage after the heating is stopped
After the heating is stopped, the heating The temperature of the facility decreases, and due to thermal expansion and contraction, it may cause water leakage at the joints and valves of the pipeline. Therefore, it is recommended to carefully check whether there is water leakage at the interface after the heating is turned off. If there is a slight water leakage, you can tie a towel. The towel will absorb the water and will not harm the floor and wall in the short term. If the leak is serious, contact the heating company as soon as possible for repairs.
Fourth, radiator cleaning method
After a heating period, the radiator gap and surface will accumulate dust, stick to oil, and become unsanitary. This requires cleaning and cleaning of the radiator. When cleaning the surface of the radiator, please use a soft towel or a brush, do not use any kind of organic solution, you can use daily detergent, such as: washing spirit, weak alkaline soapy water, etc.
5. Tips for radiator maintenance
1. Do not squeeze and bump the radiator
The radiator is usually hung in a prominent position on the wall and is vulnerable to accidental attacks such as bumping, crushing and bearing load. For the copper-aluminum composite radiator, steel-aluminum composite radiator and die-cast aluminum radiator with soft texture, if the radiator is squeezed or bumped by a heavy object, it is easy to cause the radiator header tube or the wire to be twisted and deformed, which will cause serious damage. cracked. Therefore, daily precautions must be taken.
2. Replace the old radiator in time
Heat, water seepage in welds or joints, serious surface deformation, old style, etc., the radiators that are still in use should be inspected and repaired by professional radiator installers. It is recommended to replace a new set of radiators as soon as possible. It is recommended to replace the radiators that are used over time and those that are not energy-saving and environmentally friendly, such as steel strings and old-fashioned cast iron silver powder, as soon as possible during the heating off period. When replacing, choose a radiator with high safety, energy saving, environmental protection and long service life.
Part2: Solve the problem of not heating water floor heating needs to be cleaned after heating is stopped
As a relatively new heating method, water floor heating is very comfortable and convenient. Popular with more and more families. After the heating is stopped, the water floor heating needs to be overhauled in all aspects. Let’s take a look at how to properly clean and maintain the water floor heating.
First, the necessity of cleaning water floor heating
The water in the floor heating pipe is long-term Circulation, the water contains a large number of microorganisms, and under certain conditions, a large amount of biological slime will be produced, and a large amount of slime, bacteria and scale will be produced on the inner wall of the pipeline. As for these rust and slime, it will be attached to the inner wall of the floor heating pipe, which will affect the heating temperature of the water floor heating system for a long time, and may be blocked in severe cases.
Therefore, it is best to thoroughly clean the floor heating pipes after the heating is stopped to remove the dirt and biological adhesives formed in the pipes in time. Mud, impurities and bacteria are completely removed to prevent the formation of deposits in the pipeline and cause pipeline blockage.
Second, floor heating pipe cleaning method
The current cleaning of floor heating pipe dirt, There are three main methods, namely chemical immersion, projectile cleaning and pulse wave physical cleaning. Different methods are suitable for different pipes, and it is recommended to choose according to your own situation.
Third, do not forget to maintain with full water
Like central heating pipes, After the water heating is stopped, it is necessary to fill the floor heating pipeline with water for maintenance. The correct way is to release the original water source in the pipeline, rinse the pipe network, and then refill the system with clean water and turn on the boiler for heating. When the water temperature reaches 55°C, stop heating, manually open the exhaust device on the sub-water collector, and discharge the air separated from the water out of the system.
When the exhaust work is over, close the valve in the heating system, turn off the gas boiler, let the water cool down gradually, and keep the water until the next heating period begins.
Part3: Pay attention to cleaning air conditioners and electric heaters to stop and maintain notices
As the temperature rises, the use of air conditioners or other electric heaters The frequency is also greatly reduced. Let’s take a look at the cleaning and maintenance tips for these heating electrical equipment after deactivation.
1. What you need to know about cleaning and maintenance of air conditioners in changing seasons
Many people in the south use air conditioners for heating in winter, but with the arrival of spring, many air conditioners are stopped Work, it will not be turned on until the summer heat. Therefore, it is best to thoroughly clean and maintain the air conditioner after it is deactivated, which is not only beneficial to the air conditioner but also to the health of the family. Let’s take a look at the general methods of cleaning air conditioners.
1. Turn off the power and open the panel
Before cleaning the air conditioner, cut off the power . Then hold the protruding parts of the left and right panels of the air conditioner with your fingers, and then open the panels to the stop position. Then use a soft cloth to clean the dust and stains on the surface of the air conditioner and the visible part after opening the panel.
2. Remove the filter for cleaning
Take: after opening the air conditioner panel , you can see the air filter of the air conditioner. After the air conditioner is used for a long time, a lot of dust will accumulate on the filter net. If it is not cleaned, it will not only be detrimental to human health, but also hinder the air circulation and reduce the cooling effect. When taking out the filter, generally lift the knob in the middle of the air filter slightly upwards, and then pull out the filter downwards.
When the dust accumulation on the filter screen is relatively small, it can be washed with water or cleaned with a vacuum cleaner; and when the dust accumulation is serious, it can be soaked in water containing neutral detergent for 10-15 minutes. After washing, shake off the water first and then dry it in a cool place, do not heat or dry it with high temperature.
3. Clean the heat sink
To clean the air conditioner, just cleaning the filter is not enough Yes, the heat sink also needs to be cleaned and disinfected. The heat sink is not removable, and due to the particularity of its mechanism, it is useless to wipe with a damp cloth, brush cleaning, etc., and it is easy to damage the heat sink. It is best to use a special air conditioner cleaner to clean the heat sink.
If the air conditioner is not used for a long time, it must be unplugged. It is best to cover the air conditioner with an air conditioner cover to prevent dust from entering the machine. For the air conditioner remote control, remove the battery and store it in a dry place.
2. Cleaning and maintenance after the electric heater is deactivated
1. Precautions for cleaning the electric heater
The surface of the heater can be wiped with a neutral detergent or a soapy cotton cloth, taking care to avoid main power and circuit lines. When cleaning, be sure to unplug the power outlet.
2. Notes on the maintenance of electric heaters
No need to use in warm weather When using the electric heater, first clean and dry the body and then store it. Do not store it in a humid environment, but store it upright in a dry place for reuse when it is cold.
