How to choose a domestic water heater? As people's environmental consciousness continues to be strengthened, more and more consumers tend to choose solar water heaters and air-energy water heaters, but many people don't know much about the use of this product. Here the editor will make a rough comparison of the advantages and disadvantages of electric storage water heaters and solar water heaters.
Electric storage water heater:
Advantages: simple and practical installation; can provide water; multiple channels, that is, it can be used for bathing, washing hands and vegetables.
Disadvantages: Bringing a large capacity water tank requires a load-bearing wall to install it, which also affects the appearance of an open bathroom. It must be preheated before use, and the water exceeding the capacity nominale cannot be used continuously. If there are many people in the family, you will have to wait in the middle of a bath. Additionally, unused hot water after washing will slowly cool, causing waste. When the water temperature is high, it is easy to scale and it is difficult to clean the dirt. If it is not clear, it will affect the life of the radiator.
Solar water heater:
Advantages: safe, energy-saving and environmentally friendly; can supply water to multiple channels.
Disadvantages: Installation is complex. If it is installed incorrectly, it will affect the appearance and quality of the house and the maintenance of the city is more troublesome, because the solar water heater; is installed outdoors, most of which are indoors. Roofs and roofs are therefore more difficult to maintain than electric water heaters and gas water heaters, wateris not warm enough on cloudy days, they are sensitive to lightning;
Bathroom safety tips: How to install a “safety airbag” for your bathroom
Terminal box bathroom equipotential, that is, in the bathroom, flat hot-dip galvanized steel or copper wires are used to interconnect various metal pipes, steel bars in the ground and wires protection entering the bathroom and the casings of electrical equipment. Making a “local equipotential bond” in the bathroom can keep the bathroom at the same potential, which helps reduce the potential difference and avoid dangerous contact voltages.
Nowadays, when families renovate their bathroom, they often have only two options: one is to choose a water heater and the other is energy solar. In fact, both have their own advantages.ages and disadvantages. There is no one better than the other. It all depends on the choice of each family.
Let’s talk about the water heater first. Most water heaters come in the form of water storage tanks. Easy to use, large water production, rapid heating and stable water temperature. Many ordinary households choose to install it. It is light, relatively inexpensive and takes up little space. There are many types of water heaters, and the hot water comes out very quickly and only takes a few minutes to heat up. ?
But in the same way, water heaters use electricity to maintain water temperature It uses a lot of electricity. Without electricity, heating is relatively slow; and it is prone to scale and must be kept clean and hygienic for a certain period of time. Maintenance will be relatively frequent.
Let's talk about solar energy. Apart from the first installation, solar energy rarely causes problems in the future and electricity is no longer needed in subsequent periodsThus saving energy and money compared to water heaters . It is very environmentally friendly and has a long lifespan. It is very safe to use and will not cause poisoning or electric shock. The hot water in the water tank has a good temperature and is comfortable to use.
However, the disadvantages of solar energy are also obvious. The cost of the first installation is very high, and the water temperature after collecting the heat is always maintained at a constant temperature. If it is hot, the water tank will be in a state of high temperature and pressure for a long time, which will promote aging and stripping of the seal ring and shorten the life of the water tank. water. So if you don't use it for a long time, you should find someone to drain it regularly or cover the solar. Another problem is that in winter, if the sun is not obvious, the water heater will easily run out of hot water.
