Solar water heater cleaning tutorial

The solar water heater cleaning tutorial is as follows:

1 When all the water in the water tank is drained, hold each tube empty with both hands. and rotate it back and forth. The sealing ring on the vacuum tube and the water tank is loosened and then pushed into the water tank.

2. When the bottom of the vacuum tube can be removed from the fixed base, remove the vacuum tube from the water tank.

3. Pour the water into the vacuum tube. The scale is mixed with water in the vacuum tube and rinsed repeatedly.

4. When the water flows out of the hole where the vacuum tube is installed into the water tank, install the vacuum tubes on the water tank one by one and the scale cleaning work is completed.

Cleaning Precautions

Solar water heaters have been vigorously promoted because of their energy-saving and environmental-friendly benefits.the environment, and every household with conditions has installed a solar system. water heater. Solar water heaters, like commonly used electric kettles and electric water heaters, will produce scale and need to be cleaned regularly, usually once every three years, to ensure the solar water heater's operating efficiency.

The main components of scale are calcium carbonate and magnesium hydroxide, which can be neutralized with vinegar. Therefore, vinegar can be used to clean solar water heaters. There are special solar descalers on the market that do not require it. disassembly. Can be cleaned.

Choose a cloudy day or a day without sun to give yourself plenty of time, as this series is estimated to last around 3 hours. Prepare a pair of rubber gloves to protect your hands and prevent slipping during the whole process.disassembly and assembly.

How to remove scale from solar water heaters

Yes, solar water heaters need to be cleaned every two to three years

External cleaning: Solar water heaters should be cleaned according to the instructions. If they are dirty, wipe off the dust on the surface and keep them clean to maintain high heat collection efficiency. At the faucet filter, scale in the water pipes will accumulate here, so you need to remove and clean it regularly.

When cleaning the interior: open the water inlet of the solar water heater, pour white vinegar into the water storage tank, let the water heater cycle automatically for 20-30 minutes, then open the drain outlet, discharge the white vinegar which cleaned the scale, and finally add water into the water tank. After filling with water, circulate it for 2 minutes then drain it.When cleaning, be sure to unplug the plug, close the cold and hot water angle valves under the electric water heater, and wait for the water in the cylinder to cool before cleaning.

Detailed information

Several risks of not cleaning solar water heaters for a long time

1. The thermal conductivity of scale is much lower than that of metal. is 6 to 1,000 times greater than that of scale in vacuum tubes. Scale will seriously affect the hot water temperature and may reduce the thermal energy conversion rate of solar energy or even make it inefficient. This is the reason why the water temperature of the solar water heater decreases and the water supply decreases.

2. Scale contains a variety of chemical components. Long-term precipitation and accumulation will increase the number of harmful substances in the water, which can lead toskin allergies.

3. Sludge, microorganisms and bacteria also generate many harmful substances during continuous renewal and alternating reactions over a long period of time. This can cause various skin diseases. Some women and children sometimes experience itching and red spots on the skin after taking a bath.

People's Daily Online - Water heaters require regular bathing

Solar water heaters are energy-saving and environmentally friendly water heaters environment that can make full use of solar energy. for heating, heating and water supply. However, during use, due to the large amount of impurities and salts contained in water, scale will form over time. Scale will reduce the heat conduction efficiency of the water heater, resulting in heat loss, pressure reduction and other problems.problems. If it is not cleaned in time, it will affect the life of the solar water heater.

So how do you descale solar water heaters?

Method 1. Cleaning with acetic acid

Acetic acid has a good cleaning effect and can effectively remove scale in water. The method is to mix acetic acid and clean water in a ratio of 1:1, then pour the mixed liquid into the solar water heater, let it stand for 30 minutes after filling, and then pour drain the mixed liquid and clean it.

Method 2: Cleaning with citric acid

Citric acid contains strong acidity and has a strong ability to react with scale and can completely remove scale. Mix citric acid and water in a ratio of 1:10, pour the mixture into the solar water heater, let it react naturally for 5-10 minutes, then rinse it with clean water.

Method 3: Cleaning with oxalic acid

Oxalic acid is very effective at cleaning scale, but oxalic acid is corrosive, so you need to be careful when using it. Mix oxalic acid and clean water in a ratio of 1:10, pour the mixture into the solar water heater, let it react naturally for 5-10 minutes, then rinse it with clean water.

Method 4. Machine cleaning

If the above methods cannot meet the cleaning requirements, you can consider using professional cleaning equipment for cleaning. These devices use high pressure water flow and cleaning products to completely remove scale from solar water heaters.

In short, cleaning the scale from the solar water heater is a necessary task to ensure its normal use and extend its lifespan. In order to avoid the formation of tartar, we must drink more pure water and avoid using water containing a large quantityity of impurities and salts.
