What does the color of the four core wire of the water level temperature sensor of the Nuozhi solar

There are two kinds of two-wire water temperature and water level sensors for solar water heaters, and the principle is as follows:

1. Conductive water level water temperature sensor (probe): there is also a temperature probe in the middle of the sensor, and more than 50% of the sensors of solar water heaters are conductive sensors, which have the advantage of low cost and easy installation; The biggest disadvantage is that it is greatly affected by the quality of water, easy to scale, and has a life span of about one year. Due to their low cost and ease of installation, conductive sensors are currently the most widely used water level temperature devices for solar energy.

2. Float type water level control sensor (probe): the water level and temperature of this sensor are separated. Generally, 4 floats are adopted, in the float type scheme, the installation mode of the float and the temperature probe is separated, so that they are detected in different positions, which is more accurate, the float is separated from the water tank again, and the water level is detected by the principle of the same water level, and the ambient temperature of the sensor is lower than the temperature in the solar water tank, so that the life of the sensor is prolonged.

This kind of sensor is generally made to be detachable, if the float is dirty, or scaled, it can be removed for cleaning, and it can also be used repeatedly, so that the purpose of not replacing the water level sensor during the effective life of solar energy can be achieved. The temperature probe is installed separately, which can be installed near the hot water outlet, and the temperature display is more accurate. The lifespan of temperature sensors is generally more than 10 years.

The disadvantage of the float solution is that the cost is relatively high and the installation is more complicated.

It's too bad, don't be deceived, I myself bought a 5-year free warranty nozi mobile bath machine, less than a year, there are serious quality problems: 1It can't be turned on before and after connecting to the power supply; 2.

It claims to be a stainless steel liner but has severe rust. What's even more odious is that the bad store said that the 5-year free warranty changed and said that it would be sent back for repair, and the maintenance fee would be charged.

1. Electric water heater

Electric water heaters are relatively large, and if the bathroom is already small, it will become crowded if you install an electric water heater. In addition, the water heater tank has limited water storage, so if you have multiple people taking a shower in a row, you may need to wait for time to bring water to heat before cleaning.

1. Convenience:It needs to be heated up, the volume is small, and the bath needs to be staggered, otherwise you have to wait.

2. Security:Nowadays, electric water heaters have the necessary safety measures, but they should be used carefully to avoid leakage. And when in use, the power plug should be plugged in tightly, and when not in use, it is best to unplug it.

3. Energy saving:As the name suggests, electric water heaters can only produce hot water by using electricity, which is more electricity-intensive, and I am afraid that there will be a lot of electricity bills all year round.

2. Solar water heaters

Although the solar water heater ** is expensive, it does not require electricity and gas when it is used, only the balcony can be used, so these costs can be omitted. Moreover, even on rainy days, solar energy can have hot water, because it has the function of electric heating, and is not afraid of cold water.

1. Convenience:It is generally placed on the roof of the building, which does not occupy the space at home, and as long as there is sun, there is hot water coming out, no need to wait, which is very convenient.

2. Security:The solar water heater does not have to worry about leakage and is very safe.

3. Energy saving:Although the solar water heater is high, it does not need to pay electricity and gas bills when it is used, so it is still very energy-saving when it is used as a whole.

I have installed an electric one in my house, and I also installed a solar one, and there are gas pipes in my house, but for some reason, there is no gas water heater in my house.

The electric water heater was used for six years and repaired three times; Solar energy has been used for nearly eight years, and it has only been repaired once, and the sensor has been replaced, which was replaced more than two months ago, and the last time the electric water heater was repaired by a master who repaired solar energy.

My family lives on the fourth floor, a total of seven floors, and I am very satisfied with the combination of my water heater, which uses solar water to wash dishes and vegetables in winter. Sometimes there is no water in the tank, and when the water stops suddenly, the water in the solar energy can still meet the needs of our whole family, and sometimes we also use the water in the solar energy to boil tea and drink.

After all, the life of the electric water heater can only be used for another year or two at most, if there is any problem with my electric water heater, I still consider buying a new one, I think the combination of electricity and solar energy can meet the hot water needs of our whole family. I also hope that the landlord can choose accurately.

From this aspect, it seems that the former will be more suitable, because it uses too much energy and does not need electricity, but in the case of continuous rainy days, electricity needs to be used for auxiliary heating, and the electricity bill will increase a lot, while the latter power is generally 1000 2000W, which consumes a lot of electricity, but solar energy is more troublesome to use in winter, because the temperature cannot be reached, so there is no way to use hot water.

2. Safety.

Relatively speaking, the safety of the former will be higher, because the water temperature is heated by the sun, so there is no danger, and the latter is directly heated with electricity, which may be relatively unsafe, but no matter which style you choose, the quality must be passed, so as to ensure everyone's health.

3. Installation angle.

The former needs to be placed in a high place, can not be covered by shadows, otherwise the heat can not meet the demand, the water will not become hot, so the installation is more troublesome, and the latter installation is more simple, whether it is in the first place, there is no restriction on conditions, so they both have their own advantages, users can choose according to their own situation.

Hope it helps.

It's better to use an electric water heater.

1. Investment analysis: The comparison between them has nothing to do with the cost of water. Taking a family of four as an example, assuming that a 1000w electric water heater costs 1500 yuan (including installation fee), it can be heated for 45 minutes each time, which can be washed by 2 people once, an average of 15 times per person per month.

The monthly bathing cost is 1000w * hour * yuan kWh * 2 * 15 = yuan, and the annual cost is yuan.

Assuming that the solar water heater is 2500 yuan per unit (including the installation fee should be more than 2500 yuan), then you will only see the energy savings that the solar water heater will bring you after (2500-1500) 162 = years. Excuse me: Which solar water heater lasts so long?

If there is, there are very few! Too risky!

2. From the perspective of convenience to use, the solar water heater is not hot when it wants hot water, and it is so much when it is not wanted. For example, if you want hot water in winter, you don't have it; Summer is less, but it's too much!

Answer: Hello, water heaters are relatively practical. Water heaters are generally gas water heaters, natural gas water heaters and electric water heaters, which have no restrictions on their use, and are all heated by gas, natural gas and electricity. Solar energy, on the other hand, is heated by the conversion of the sun's energy.

It is generally used in rural areas and is not suitable in urban areas. Therefore, solar energy has limitations in terms of use. And it's cheaper to have a water heater than solar energy on it.

But in terms of safety, solar energy is a bit safer than water heaters.

1. Investment analysis: The cruel market competition has brought the solar water heater close to the production cost, and now you can buy a solar water heater for more than 1,000 yuan, which is almost the same as buying an electric water heater.

When there is no sunlight, a solar water heater is purely an electric water heater with a large capacity. Many people know that they can't get sunlight (blocked by other buildings), but still install solar energy, and the picture shows the super large capacity electric water heater with enough hot water (no matter how big the bathtub is). The capacity of an electric water heater is usually 50 liters, while the capacity of a solar water heater is generally more than 150 liters, with one top three; If the two are almost the same, fools will know which one is better to buy.

It can be seen that solar water heaters can win without sunlight, not to mention that the sun will always take care of it?

In addition, it has been 6 years since the solar energy was installed in 2006, so which solar water heater cannot be used for 6 years? Even if it is less than 6 years old, it is rare! Will the risk be great!

2. From the perspective of ease of use, this needs to be seriously considered! For example, the solar water heater pulls down the water pipe from the roof of the building is longer, and the hot water downstairs needs to wait for a while, and the cold water in the original water pipe must be discharged first, so the solar water heater is only suitable for bathing and bathtubs that need a large amount of hot water, and the washbasin and vegetable basin that need a small amount of hot water and are used frequently should be provided by a small electric water heater (Chubao); Another example is

It's not easy to use, it's applicable.

The conditions involved in using a solar water heater are as follows:

1. How far is your home from the top floor? If your home is the top or penultimate floor, you can, otherwise it will be too water-intensive.

Before taking a bath, you must put away all the cold water stored in the outlet pipeline, and the hot water from above should be warmed up along the pipeline, so that the sprinkler head will produce hot water, if the pipeline is too long, it will make you very water-consuming. And the interval between putting water when taking a bath should not be too long, otherwise the pipeline water will have to be cooled again. If your home is on the top or penultimate floor, although you also need to have this process, it may still be able to withstand it if the pipe is not too long.

After all, solar energy does not consume electricity, and the electricity saved is enough.

2. The property of the community is not allowed.

3. Whether the load bearing on the roof is allowed.

4. Whether the suitable position on the roof has been occupied.

Relatively speaking, the advantage of an electric water heater is that there is no waste of cold water.

The disadvantage is that it is definitely more expensive than a solar water heater.

Weigh it up for yourself.

The solar water heater is good, and the current solar water heater supports the electric heating function, and the full smart mode is very energy-saving.

Which is better electric water heater or solar water heater? I regret that I made a mistake and suffered a big loss.

My family has just installed Sanglas solar energy, and now the temperature is very low in this season, so you don't have to expect to use it to take a bath, turn on the electric heating function, and the temperature rise is even slower, compared to the original electric water heater, which is far worse, and the temperature rises quickly.

Or you have to weigh it yourself.

Of course, solar energy is easy to use, and there is hot water as soon as you twist it, and you don't have to pay for electricity.

The brother upstairs answered yes It is not recommended to connect to the ground heating, if your solar energy is large enough, you can consider connecting it to the water air conditioner for circulation, of course, the connection method is also very simple, but to ensure that the solar energy of your home is large enough, the water content is at least 200L or more, and the most important thing is to have an electric auxiliary function.

Is your home balcony solar or rooftop solar? Do you want to send solar water to a floor heating boiler? Or do you want to bathe with floor heating on a rainy day?

Don't pick it up. Because come, 1, compared with the heat dissipation of the source home and the heating capacity of your solar bai, it is too little du, not enough for you zhi

We're hot up.

2. If solar energy is connected with heating, if it is central heating, the water in the heating pipeline is soft water, mixed with domestic water, and the consequences are unimaginable.

3. You also need to add another pump to get the system running.

To sum up: it takes a lot of money, it doesn't work, and it brings a lot of trouble, so why bother?

First of all, solar heating is available.

bai to achieve.

Secondly, there are several issues that must be noted at DU:

1.Ordinary household zhi

Solar water heater uses sunlight to generate heat, without consuming electricity, but only uses a small amount of electricity for the control circuit, which can be a lifelong benefit from an investment. However, the water temperature is not high enough on cloudy days, and the heat dissipation is fast due to the low outside temperature in winter, and if it is cloudy again, the water temperature is very low.

The electric water heater is not affected by cloudy days, as long as there is electricity, it has been turned on and has hot water at any time, but it consumes more electricity and costs a lot. There are pros and cons to both, depending on how you use them. If the water consumption is not large, it is more cost-effective to choose a solar water heater.

Of course, both are better, the advantages and disadvantages are complementary, the electric water heater can be used as a backup, only in the cloudy day when the water temperature of the solar water heater is not high enough or when the amount of hot water is large, and then turn on the electric water heater, in the case of saving electricity as much as possible, it can also ensure the hot water.

2. Structure: It consists of collectors, thermal insulation tanks, brackets, connecting pipes, control components and other components.

3. Working principle: the sunlight shines through the first layer of glass of the heat absorber tube to the black heat absorption layer of the second layer of glass, and absorbs the heat of sunlight energy, because the two layers of glass are vacuum insulation, the heat transfer will be greatly reduced (radiation heat transfer still exists, but there is no heat conduction and heat convection), and most of the heat can only be transferred to the water in the glass tube, so that the water in the glass tube is heated.

The heated water enters the thermal insulation storage bucket along the heating surface of the glass tube lightly, and the water with relatively low temperature in the barrel enters the glass tube along the backlit surface of the glass tube to supplement, so that the water in the thermal insulation storage bucket is continuously heated, so as to achieve the purpose of hot water.

Solar water heaters convert sunlight energy into heat energy and heat 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 vacuum tube solar water heaters are the mainstay, accounting for 95% of the domestic market share. The vacuum tube household solar water heater is composed of a collector tube, a water storage tank and a bracket and other related accessories, which mainly rely on the collector tube to convert solar energy into heat energy.

The collector tube uses the principle of floating and cooling water to make the water micro-circulate to achieve the required hot water.

Endothermic process. During the heat absorption of a vacuum tube water heater, the solar radiation passes through the outer tube of the vacuum tube, is absorbed by the heat collection coating, and then transmits the water to the tube along the inner tube wall. After the water in the tube absorbs heat, the temperature increases, and the specific gravity decreases and rises, forming an upward power and constituting a thermosiphon system. As the hot water moves up and is stored in the upper part of the tank, while the cooler water is replenished along the other side of the pipe, and so on, the whole tank of water rises to a certain temperature.

Plate water heater is generally a split water heater, and the medium is naturally circulated in the collector plate due to thermosiphoning, and the heat of solar radiation in the collector plate is transmitted to the water tank in time, and the heat is transmitted to the cold water through heat exchange (jacket or coil) in the water tank. The medium can also be transferred by means of a pump circulation.

Circulating lines. Home solar water heaters usually work in a natural cycle and have no external power. Vacuum tube solar water heaters are in-line structures, and the hot water is powered by gravity. Flat panel solar water heaters are powered by the pressure of tap water, known as top water.

The solar central heating system uses pump circulation. Due to the small collection area of solar water heaters, pipe circulation is generally not used considering the loss of heat energy.

Usage process. The flat panel solar water heater works in the top water mode, and the vacuum tube solar water heater can also work in the top water mode, and the jacket or coil mode can be used in the water tank. The advantage of top water work is that the water supply pressure is the tap water pressure, which is larger than the natural gravity pressure, especially when the installation height is not high, and its characteristics are that the water temperature is high and then low in the process of use, which is easy to grasp and easy for users to adapt, but the tap water is required to maintain the water supply capacity. The cost of solar water heaters with top water working mode is higher than that of heavy power water heaters.
