Is it better to buy a solar or electric water heater for my family?

Solar water heater is a one-time investment, energy saving and environmental protection, Shanxi where the sun intensity is very good, the installation of solar energy is indeed good, and the solar water heater itself has an auxiliary electric heater, if the weather is not good when the water temperature is not enough, the water temperature in the tank can be raised through the auxiliary electric heater, which is convenient for users to use, but your floor is too low, you need to put a lot of cold water hot water to come out.

The storage electric water heater is really expensive to use in winter, but in summer, you can take a bath after about 20 minutes of electric heating, but even if you take a bath alone in winter, you must buy a 50-liter electric water heater, otherwise the hot water is not enough.

Since it is not commonly used, then buy an electric water heater because your home is on the first floor and it is still six floors If you use solar energy, you will put too much cold water in terms of water saving, and it is not cost-effective in terms of water saving Is there still the north In winter, the amount of sunshine and solar heat are not very good Three people take a bath, and it is not much power about 2000 to 3000 It is OK At most two kilowatt-hours of electricity at a time.

To put it mildly, we do decoration, and generally do not recommend users to use solar water heaters. Because there are many requirements for the use of solar water heaters. Affecting the appearance, many cities are not allowed to install it.

The only benefit is that it is more energy-efficient. Use It is generally not allowed to use very hot water for bathing, and it is enough to buy a 40-50 liter storage type electric water heater. For ease of use, if possible, it is best to use a mix-and-match:

Storage Electric Water Heater + Gas Water Heater, Storage Water Heater + Air Energy Water Heater, Gas Water Heater + Air Energy Water Heater.

I think it's better than an electric water heater. Because your home is on the first floor, it is not convenient to install solar energy. And there are not many people who use it, and the number of times it is used is also small, so you should use the electric water heater first. Convenient, fast and cost-effective. Electric water heaters won't be unaffordable, they are more than solar-powered ones!

Buy an electric water heater, the solar water heater is too affected by the weather, and it can't be used for 5 months a year, even if there is electricity to assist heating, it is still practical to install an electric water heater, and the cost accounting is still the accounting of electricity.

I'm from Taiyuan.

I suggest you buy an electric water heater because you don't take a shower every day, how much electricity is used in the electric water heater, and the solar water heater depends on the weather.

There should be a mix of the two, solar energy when there is sun, and no water heater is used.

Solar water heaters are more practical than electric water heaters and have many advantages. Most of the solar energy is heated by sunlight, the danger is very small, the danger of the electric water heater is relatively large, you need to unplug the power supply when taking a bath, and also install protection functions such as anti-electric walls, the maximum service life of the electric water heater is 8 years, if you don't maintain it well, it is easy to age and burn the land will have great potential safety hazards. Although the electric water heater is convenient to install in the early stage, it needs to be cleaned and maintained regularly in the later stage to prolong its life.

Tips for choosing a solar water heater:

1. Look at the quality of the vacuum tube. The vacuum tube is a key component of the water heater, and the amount of heat obtained by the vacuum tube under the same external conditions directly affects the water temperature. When purchasing, carefully observe the coating on the glass tube in the vacuum tube, its color is generally black, dark blue or dark gray, the coating color is uniform, the film layer has no scratches, no peeling or peeling, there are no stones on the glass, and the support is placed upright and not loose.

2. Look at the material selection and process technology of the insulation layer and the inner tank. There is a layer of insulation material between the shell and the inner tank of the solar water heater tank, which plays a very key role in hot water insulation, and the service life of polyurethane insulation materials can reach more than 15 years. The inner tank is the place where hot water is stored, preferably with a stainless steel plate, with a thickness of about 0 5 mm.

In short, consumers should choose imported polyurethane and water tanks with thick insulation layer. Because the insulation layer and inner tank of the water heater are inside, it is not easy for consumers to see, so it is better to buy products with a good reputation in the market and guaranteed in terms of product quality, performance, and service.

3. Look at the thermal performance index. It is not that the higher the temperature of the water in the tank, the better the thermal performance, but the higher the average daily efficiency, the better, and the lower the average heat loss coefficient, the better. The second is to see whether the pressure test of the water heater is qualified, and if the pressure test does not meet the standard, it will easily lead to the leakage of the water heater, which will waste hot water and cannot be used.

The current status of energy-saving technology of my water heater:

1.The solar water heater is an energy-saving product, but it is also equipped with an electric heater, which is more than 15% likely to be used when using hot water in rainy and cold weather or in the morning.

2.The advantage of gas water heater is that its heating power is large, about 5 kilowatts, and hot water can be used at any time, but the installation is troublesome, and it is dangerous to use it improperly.

3.In the area where the peak-to-valley electricity price difference is implemented in Liangtuanqin, the electric heating hot water with low electricity prices at night is used, that is, the storage electric water heater technology, which is a commonly used technology in foreign countries, and almost every household is equipped with hundreds of liters of thermal storage water heater; Nowadays, the electricity consumption in various places is very tight, and energy is very scarce, and the use of solar water heaters can save a lot of energy and prevent pollution. Using a solar water heater** is much cheaper than using an electric water heater, saving at least two-thirds of the electricity and gas used.

Therefore, it is recommended to choose a solar water heater.

Cost-effective: black porcelain, old or nuclear, ceramic, solar.

1) The vertical 90° is easy to install, making the façade of the building more safe and reliable.

2) The heat-absorbing coating adopts ceramic technology, so that the heat-absorbing coating does not decay for a hundred years and is resistant to air exposure.

3) The physical connection method is adopted to solve the problem of electrolytic corrosion caused by heterogeneous metal welding, and the effective life is as long as 50 years.

4) It can realize building integration, replace building construction, and save civil construction costs.

Each has its pros and cons: solar energy Fengzen saves money, environmental protection and energy saving, but it is easy to freeze if it is not well kept in winter, and silver dust must be used to assist heating on rainy days; The electric water heater is convenient, the hot water is fast, and it is not affected by the environment, but it consumes electricity, and you need to wait if you need hot water to boil.

Solar energy is practical.

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.

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

Safety: The solar water heater does not have to worry about leakage, it is very safe.

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

Most of the solar energy is heated by sunlight, the danger is very small, the danger of the electric water heater is relatively large, you need to unplug the power supply when taking a bath, in addition to installing the protection function of the electric wall, the maximum service life of the electric water heater is 8 years, if you do not maintain it well, it is easy to age and there will be great safety hazards.

Solar water heaters do not need gas and electricity to add, which is energy-saving and environmentally friendly, and is safer to use. However, modern solar water heaters are equipped with electricity-assisted heating, solar heating is the mainstay, supplemented by electric heating, in short, you can take a hot bath all year round.

1. If it is from the aspect of power saving, of course, it is better to use solar energy to heat up, it will rarely use electricity, usually only in the case of consecutive rainy days, will use electricity to assist heating, electricity will increase to a certain extent, and then the power of the electric water heater is generally 1000 2000w, power consumption is large, but solar energy is more troublesome to use in winter, because the temperature can not be reached, so there is no way to use hot water.

2. Which one is more suitable for safety: relatively speaking, the safety of solar energy will be higher, because the water temperature is heated by the sun, so there is no danger, and electric heating is to directly heat water with electricity, which may be relatively unsafe, but no matter which style is chosen, the quality must be passed, so as to ensure everyone's health.

3. How to choose the 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 installation of the latter is more simple, whether it is in the first place, there is no restriction of conditions, so they both have their own advantages, and the user beam can be selected according to their own situation.

Solar water heaters and electric water heaters have their own advantages and disadvantages. Solar water heaters are energy-efficient, but they are more troublesome to use in winter, and it is not easy to control the water temperature; Electric water heaters are easy to use, but they consume a lot of electricity and need to pay an electricity bill. In terms of safety, solar energy is safer, while electric water heaters can be dangerous.

In terms of installation, electric water heaters are more convenient, while solar thermal water heaters need to be installed in a high place and cannot be covered by shadows. In general, the choice of which type of water heater to choose should be decided according to your actual situation and needs.

Which is better, solar water heater or electric water heater? What is the reason why the solar water heater does not produce hot water? In fact, all kinds of water heaters have their own advantages and disadvantages, and consumers should choose water heaters according to their actual life needs.

Let's take a closer look at the relevant knowledge content today.

1. The solar water heater is a device that converts sunlight energy into heat energy, and its main structural forms are vacuum source tubular type and flat plate type. Another example of the outside solar water heater electric water heater is safer, too it uses sunlight to heat the water temperature, there is no danger.

2. The heating method of electric water heater is mainly conductive heating. If it is not cleaned for a long time, it will increase the thickness of the dirt and affect the heating efficiency. At the same time, thick scale will make it impossible to conduct heat, bringing potential safety hazards.

3. In contrast, solar energy, as a renewable energy source, has the characteristics of environmental protection and pollution-free, so it has a good effect of sewage purification and makes the water source cleaner.

4. In terms of power consumption, the power consumption of general household electric water heaters is usually about 1500-2000W a day, and the power consumption is relatively moderate. Solar energy is slightly smaller than ordinary electric water heaters, but on cloudy or rainy days, its power consumption will increase significantly, which brings a lot of trouble to users.

5. In terms of service life, solar water heaters can be used for 12-15 years under normal circumstances, while electric water heaters can be used for 8-10 years. It can be seen that solar water heaters are more worth buying.

What is the reason why the solar water heater does not produce hot water.

1. Insufficient water pressure.

Too little water pressure can cause water heaters to fail to produce water, especially in remote rural areas, which is a common occurrence.

2. String water. The situation of stringing water will also cause the solar water heater to not produce water. In the event of a string of water, the water heater is unable to heat up, resulting in ice water or no water coming out most of the time.

3. The water valve is faulty.

A problem with the water valve can also cause the water heater to come out of the water. The water valve is the key device to control the water source outlet, once there is any problem with the water valve, it will affect the water heater water outlet effect, in other words, the water valve failure, it is easy to lose control of the water, and eventually cause an accident.

Therefore, the user needs to install an independent water valve, and the valve should be tightly closed, which can effectively reduce the hail of water strings, and at the same time, it is necessary to do timely inspection and maintenance.
