How small liters should be for home solar water heaters!! 15

Depending on the size of the family, it is decided:

I am a family of 3 and use 50 litres of solar energy, which is well used and meets the needs.

It is calculated according to the amount of water used in winter. For 4 people, each person can be calculated according to 40 80 liters, it is more appropriate to buy more than 200 liters, it does not matter in summer, but it is appropriate to be larger in winter.

The current brand of solar water heaters, the quality is the same, there is not much difference, the highlight is Huangming and Yijianeng, but the ** is too high. It can be purchased according to its own situation, but it should be noted that when purchasing and installing, other accessories must be produced by the original factory, such as connecting water pipes, water valves, electric heaters, etc., and should have the original factory mark.

Specifically, ask me: Are there any elderly or children in the family of four you are talking about?

Generally speaking, 50 litres of bathing water for adults and 25 litres for the elderly or children.

Therefore, it is recommended that you buy a 120-liter one.

You use less hot water in the summer, more hot water in the winter, and if you don't use solar energy in the winter, you can make it smaller.

As for the advantages and disadvantages of solar energy, I will summarize it roughly: the advantage of solar energy is that it is a one-time investment and long-term benefits; clean energy; It is convenient to have the sun that is hot.

There are also disadvantages: electric heating must be turned on on rainy days (power consumption); Not available in special weather such as thunder (for safety reasons); The longer you use it, the more likely it is to need repairs. So you need to pay attention to how to use it.

Random, please forgive me if I don't get it.

58*180 to buy 18 tubes is enough for about 2000.

The capacity is large and small, generally about 120 liters, almost enough for a family of three, of course, try to buy a larger one, buy a small one, you will regret it!

The capacity of solar water heaters can vary depending on the size of your household and the use of hot water.

From 135 liters to more than 300 liters.

<> solar water heaters.

The volume is generally 80 liters to 620 liters. Solar water heaters are liters of silver that will be sunlight.

The device that can be converted into heat energy heats water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube type Taiyou non-yang energy water heater and flat plate type solar water heater according to the structural form.

This answer is applicable to Haier and Wanjiale Shenxiaona.

Most brands of water heater models such as Midea.

Generally, the hot water temperature reaches 38 degrees in summer, and it takes about 6 or 7 minutes to rise one degree, and the hot water temperature reaches more than 45 degrees in winter, and it takes about 10-12 minutes to rise one degree.

The heat of electricity per kilowatt-hour is 860k, the conversion rate is 92%, 200 liters of water are heated from 20 degrees to 70 degrees Celsius and 50 degrees, and the electricity consumption is 200 * 50 (860 * 92%) = kilowatt-hour electricity, and it takes time to heat with electricity: hours.

It takes time to heat with electricity: hours, if the water at 70 degrees is exposed indoors at 10 degrees, it will get cool in about 20 minutes, if it is inside the tank, the temperature drop of a good water tank in general will not exceed 10 degrees in 24 hours a day, and the best will not exceed 5 degrees.

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

Solar water heater is a heating device that converts sunlight energy into heat energy, heating water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, and the company is mainly based on vacuum tube solar water heaters, accounting for 95% of the domestic market share.

Vacuum tube household solar water heater is a fibrous cover is composed of heat collector tube, water storage tank and bracket and other related spare parts, the conversion of solar energy into heat mainly relies on vacuum collector tube, vacuum collector tube uses the principle of hot water floating and cold water sinking, so that the water produces microcirculation and gets the required hot water.

<> The capacity of solar water heater is generally how many liters: 80 liters swim 620 liters, solar water heater is a device that converts sunlight energy into heat energy, heating water from low temperature to high temperature, so as to meet the use of hot water in people's life and life; Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form.

This answer is applicable to most brands of water heater models such as Wanhe, Haier, Wanjiale Shengyin, etc.

Dear, hello, I am happy to answer for you: how to calculate how many liters of solar water heater A, dear Hello Five thin pipes are multiplied by about 8 liters of water, and eight are multiplied by about 10 liters, if you look at my water consumption, I recommend that you buy a larger solar water heater to ensure that the hot water is enough, it depends on which style of solar water heater you have, and the five thin pipes are multiplied by about 8 liters of water, and eight are multiplied by about 10 liters, which can know the approximate water storage capacity. Whether the amount of hot water is enough or not depends on the living habits of each person's family, some people, the bath time is longer, it is more water-consuming, and some people take a bath for a short time, so it can not be generalized.

If you follow my method of using a solar water heater, I recommend buying a larger one. If the solar water heater is normally used by the slow burial method, the temperature will be very high most of the year, and it is necessary to add cold water to the top of the hot water to use, then if there is 180 liters of hot water in the water tank, it may be equivalent to 360 liters of water when actually used. However, in this process of cold water topping hot water, because the cold water pressure is unstable, the water temperature will fluctuate from cold to hot, so I suggest that it is better to buy a solar water heater with a larger capacity.
