Consumers often believe that the more power an appliance has, the higher the power consumption. With the progress of society, there are more and more types of water heaters. We usually see instantaneous electric water heaters and storage electric water heaters, and many homeowners don't know how to choose which one is better. Now let me give you a detailed introduction to these two types of electric water heaters!
1. Instantaneous electric water heater.
Instantaneous electric water heaters do not require a large capacity water storage tank, hot water can be used at any time, the heating time is short, and hot water can be obtained in just a few seconds. This kind of water heater is very suitable for families, hotels, schools and other places that need to use hot water at any time, avoiding the embarrassment and trouble of waiting for subsequent users, and can continue to use hot water. Since it is ready-to-use and does not require water storage, it is very small in size and suitable for bathrooms with limited space.
2. Storage type electric water heater.
The storage type electric water heater is our common traditional electric water heater, it has a large water storage tank, and the capacity of the water storage tank should be selected according to the number of people who use it at the same time, so as to avoid the water storage tank capacity is too small and the hot water is not enough. The larger the volume of the storage type electric water heater, the more space it occupies, the heating power is about 3000 watts, the requirements for the circuit are not high, and ordinary household wires can be used 25 square line dedicated line. However, the load-bearing capacity of the wall needs to be considered when installing, because storage type electric water heaters are heavy when filled with water, and if the wall cannot bear the weight, there is a risk of falling. Due to the long-term storage of water in the water storage tank, the tank and pipes are prone to fouling, and the magnesium strips need to be cleaned and replaced regularly.
3. Comparison of instantaneous electric water heaters and storage electric water heaters.
1.Comparison of heating times.
Storage water heaters have a small amount of power, but depending on the capacity, they can heat up for anywhere from 30 minutes to 2 hours. Whereas, the heating time of an instantaneous electric water heater depends on the length of the bath. In spring, summer and autumn, only 1-2 kilowatts of power are needed to meet the demand, and the average power throughout the year is about 4 kilowatts. If the bath time is about 10 minutes per person, the bath cost is only 0About 5 yuan.
2.Energy Saving Comparison.
As we all know, energy savings mainly depend on the degree of waste of electrical energy. Instantaneous electric water heaters do not need to be preheated and do not need to store hot water;With a thermal efficiency of more than 95%, it consumes as much electricity as much hot water is used, and there is almost no waste. Traditional storage electric water heaters need to store hot water for 24 hours and continuously dissipate heat and heat preservation, which consumes nearly 2 kilowatt-hours of electricity per day.
In addition, if you use a conventional water heater to take a bath, when the water temperature drops to 40 degrees Celsius, if you add cold water, the water temperature will continue to drop and you will not be able to continue bathing (generally the optimal bathing temperature is about 40-45 degrees Celsius). Instantaneous electric water heaters, on the other hand, can be heated as often as needed to ensure stable hot water**.
3.Comparison of bathroom decoration space.
There is a huge water storage tank inside the storage electric water heater, which occupies valuable indoor space and affects the aesthetics of the interior decoration. The instantaneous electric water heater is small and exquisite, easy to install, and is very suitable for the decoration of small toilets in the city. Storage water heaters are prone to fall off the wall after being filled with water, causing injury accidents, while tankless water heaters do not have this problem.
4.Installation comparison.
Instantaneous electric water heaters are small in size and flexible and easy to install. Whether it's a toilet or a hallway, you only need to pre-arrange the hot and cold water pipes to install it. Traditional storage electric water heaters, on the other hand, have a large tank, which is bulky and heavy, and needs to be installed on a load-bearing wall. This will not only affect the decoration effect, but also have certain safety hazards.
5.Cleaning comparison.
Tankless electric water heaters are heated by passing water and do not produce limescale, so they do not require special maintenance. However, the traditional storage type electric water heater is prone to scale due to the static water being placed in the inner tank for heating. The process of removing limescale is cumbersome and expensive, and maintenance is inconvenient. In addition to regular circuit security checks, instantaneous electric water heaters basically do not need to be maintained and cleaned, which is very worry-free.
6.Volume comparison.
Instantaneous water heaters are small in size and perfect for small bathrooms in Chinese homes. It solves the bulky and space-consuming problem of traditional storage electric water heaters.
Fourth, the purchase skills of instantaneous electric water heaters.
1.Consider energy efficiency:
Research different brands and models of instantaneous electric water heaters to see how they perform in terms of energy efficiency. You can get more information about the energy efficiency of each product by browsing the official website**, reading product brochures, and comparing user reviews. Choosing products with higher energy efficiency can reduce energy consumption and save on electricity costs.
2.Read product reviews and user reviews:
See what other consumers are saying about your product's performance, experience, and safety. This allows for a better understanding of the product's strengths and weaknesses so that you can make more informed purchasing decisions. You can refer to professional product reviews** or **user reviews of your store.
3.Seek professional advice and advice:
Consult the advice and advice of a professional, such as an appliance salesperson or repairman. They may have a deeper understanding of different brands and models of instantaneous electric water heaters and can provide more targeted recommendations based on your needs and budget. Their expertise can provide you with a more valuable reference.
4.Refer to the safety certifications and related standards of the product:
Check if the product is certified for safety and complies with the relevant standards. For example, you can pay attention to whether the product has obtained national or international safety certification marks, such as 3C certification. These certifications and standards prove that the product complies with the regulations in terms of safety and has been inspected and verified by the relevant authorities. Choosing a product that has passed the safety certification can improve the safety of use.
5.Compare ** and Warranty:
When considering buying a certain instantaneous electric water heater, compare the different brands and models** and warranty policies. In addition to focusing on the performance and quality of the product, it is also necessary to consider the matching with the budget and the quality of after-sales service. Choosing a product that is reasonable and offers a long warranty period can get a better buying experience and after-sales support.
