How many liters of water can a normal solar water heater hold?

Ordinary solar energy can generally store 100 to 350 liters of water.

Solar water heaters are heating devices that convert sunlight into heat energy, heating water from low temperature to high temperature to meet people's hot water needs in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural form, with vacuum tube solar water heaters being the main type, accounting for 95% of the domestic market share.

The vacuum tube household solar water heater is composed of related parts and components such as collector tubes, water storage tanks and brackets. The conversion of solar energy into thermal energy mainly relies on vacuum collector tubes. The vacuum collector tubes use the principle that hot water floats and cold water sinks to create microcirculation of water and obtain the required hot water.

How to clean a solar water heater

To clean a solar water heater, you can remove the solar vacuum tube, soak it in white vinegar for 10 minutes and scrub it directly with a brush, or you can pour white vinegar into the water tank for cleaning, let the water heater circulate automatically for 20 to 30 minutes, open the drain to drain the white vinegar, then fill the water tank with water and circulate it for 2 minutes. After draining the water, it is clean.

1. Remove the solar vacuum tube, pour a proper amount of white vinegar into it and soak it for 10 minutes, use a brush to scrub the scale on the tube back and forth, then pour water into the tube, shake it several times and then pour out the water, and rinse it repeatedly. Be sure to handle it with care when cleaning, as the vacuum tube is very easy to break.

2. If the vacuum tube is difficult to remove, open the water inlet of the solar water heater and pour white vinegar into the water tank. Let the water heater circulate automatically for 20 to 30 minutes so that the white vinegar can fully contact all parts and clean them more thoroughly. Then open the drain and drain the white vinegar. Finally, fill the water tank with water again and circulate for 2 minutes, then drain the water.

3. Buy a special solar descaling agent, mix it with water in a ratio of 1:10, and pour it into the water storage tank. Let it circulate automatically for 20 to 30 minutes, then drain the descaling agent directly from the drain. Fill the water tank with water and circulate it for two minutes, drain the circulating water, and the dirt removal work is complete. If it has not been cleaned for a long time, you can directly pour in the descaling agent.

Disadvantages of solar water heaters

The installation requirements of solar water heaters are very strict. They need to be installed on the roof, which can easily damage the waterproof layer of the roof. Solar water heaters need sunlight to heat the water. When the weather is bad, it is difficult to use hot water. Solar water heaters need to drain the hot water frequently and then refill with cold water, which is very troublesome.

The installation requirements for solar water heaters are very strict. They need to be installed on the roof, which can easily damage the roof's waterproof layer. If the installation is unstable, there will be safety hazards, and daily cleaning and maintenance will be very troublesome.

Solar water heaters need sunlight to heat the water. When the weather is good, hot water is only available at night, and there is no guarantee of hot water supply throughout the day. If the weather is bad, it is difficult to use hot water.

Solar water heaters require the hot water to be drained frequently and then refilled with cold water to avoid the water tank being in a state of high temperature and high pressure for a long time, which will lead to aging of the sealing ring. Excessive pressure will cause the water tank to swell and shorten the life of the water tank.
