Is it good to have solar energy at home or an electric water heater?

In life, many people ask whether it is better to install a solar water heater or install an electric water heater. The answer to this question can be said to be different, which makes the friends who see it more hesitant and confused. Today, Xiaobian, as a person who came over, said something to everyone.

1, first of all we have to solve the water pressure problem, if the water tank is lower than the solar water heater, that is, if the water pressure is very low, then there is no water supply, the pressure is not enough to install a booster pump to solve! 2, the water in the solar water heater tank will not Frozen, the inlet and outlet pipes will freeze! Need to do insulation measures! As for the winter without the sun, you can use the electric heating tube to heat! The difference between the two is as follows, for your reference!

Advantages and Disadvantages of Solar Water Heaters: At present, the solar water heater with the highest level of technology is a vacuum collector solar water heater. The water in the vacuum tube uses the principle of hot water floating and cold water sinking. After absorbing the solar heat energy, the water in the water storage tank is heated by the temperature difference cycle.

Advantages: safety, energy saving, environmental protection, and economy. In particular, solar water heaters with auxiliary electric heating function, which is based on solar energy and supplemented by electric energy, enables solar water heaters to be used throughout the year.

Disadvantages: complicated installation, such as improper installation, will affect the appearance, quality and city appearance of the city; maintenance is more troublesome, because solar water heaters are installed outdoors, mostly on the roof and roof, so compared to electric water heaters and gas water heaters More difficult to maintain. water heater:

The storage type electric water heater is divided into two types: closed type and open type. The storage type electric water heater is clean and hygienic, does not need to be installed in a compartment, does not generate harmful gas, and can be easily adjusted in temperature. The open type water heater liner is not resistant to pressure and cannot supply multiple waters at the same time; the enclosed electric water heater liner can withstand pressure and can supply multiple waters at the same time. Advantages: It can adapt to any weather changes. Ordinary households can be installed and used directly. Most of the electric water heaters currently on the market also have anti-shock devices.

Disadvantages: It is bulky, takes up large indoor space, is easy to scale, and wastes a lot of energy. The latest electric water heater has built-in anode magnesium rod descaling device, which solves the problem that the product is easy to scale. However, the anode magnesium rod has to be replaced once every two years, causing trouble for maintenance. The electric water heater selects the material and thickness of the inner tank of the inner electric water heater, and the welding process determines its life. Although the stainless steel liner is corrosion resistant, it is difficult to weld and has the shortest life (generally 2 years). It is basically eliminated at present; the enamel liner and titanium liner have high technical content and are widely used by professional water heater manufacturers.

Is the electric water heater round or square? Because only the design of the round pot is the most uniform and most resistant to high pressure, and the square or other shapes are not evenly stressed and can not withstand high pressure, so if you want electric water heater The pressure resistance is the strongest, and it is best to choose a round design. If the long-term calculation, solar water heaters are not economical water heaters! Because its heating is mainly solar energy! (Long-term electricity costs will save a good) Only the initial investment of solar water heaters is more expensive than electric water heaters! Some friends say solar water heaters It can't be used during cloudy days, but nowadays solar water heaters can be equipped with auxiliary electric heating function. It is mainly based on solar energy and supplemented by electric energy, so that solar water heaters can be used all day round. The products manufactured by regular manufacturers are generally safe in terms of safety! You can choose some of the more common brands of water heaters! As long as they are not produced by small workshops! If you use long-term calculations, it is more cost-effective to use solar water heaters than electric water heaters! Most of the time is heated by solar energy, and the electricity bill is left! Only the initial investment is slightly more expensive! If it is cloudy or without the sun, it can also be heated by auxiliary electric heating (the working principle is the same as that of the electric water heater)! So in comparison , solar water heaters are more cost-effective and practical!
