How to choose a water heater, how to choose a water heater for a water heater

How to choose an electric water heater:

1. When choosing an electric water heater, consumers should choose a brand electric water heater. Choosing a brand electric water heater can better solve the "safety" point, the general brand electric water heater will have a built-in patented anti-electric wall technology, real-time safety protection, not only to solve the problem of leakage of the product itself, but also to completely eliminate all the hidden dangers of electric shock caused by the live ground wire, and cut off the hidden danger of electric shock.

2. The key to whether the electric water heater is good lies in the inner tank. The inner tank is like a human brain, and its quality and operating life are all related to the safety of an electric water heater. A good liner must withstand many pressure tests.

The high-quality liner has anti-solvent, anti-riot, anti-acid, strong quality, and strong guarantee. Generally, brands of instantaneous electric water heaters will illustrate this.

3. Whether the electric water heater is good depends on the installation, and sometimes the safety accident of the water heater may also be caused by the wrong installation.

Extended Information: An electric water heater is a water heater that uses electricity as an energy source for heating. It is one of the three major water heaters alongside gas water heaters and solar water heaters.

Electric water heaters can be divided into three types: water storage type (also known as volumetric type or heat storage type), instant heating type, and rapid heat type (also known as semi-water storage type) according to the heating power.

Although the volume of ordinary quick-heating electric water heater and dual-mode electric water heater is about the same, the internal structure is very different, and the quick-heating electric water heater is only smaller in volume and more powerful than the storage electric water heater, so it is indeed faster than the storage electric water heater in terms of heating speed, but it can not achieve instant heating in spring and autumn, and it needs to be preheated, that is, it needs to wait, and the dual-mode electric water heater can be used in the three seasons of spring, summer and autumn.

With the development of society and the continuous innovation of science and technology, the upgrading of water heaters is also quietly carried out. As a daily electrical appliance, the water heater has been updated several times. Every update means a step forward in artificial intelligence.

At present, there are two types of water heaters that we often see in the market, which are gas water heaters and electric water heaters. Because gas water heaters need oxygen to support combustion when in use, they also produce a lot of exhaust gases. If you buy a gas water heater, the installation location should have a power supply, air source, exhaust holes and a good ventilation environment.

If these conditions cannot be met, you can only buy an electric water heater, let's take a look at the difference between an electric water heater and a gas water heater. 1. Advantages and disadvantages of gas water heaters and electric water heaters 1The advantage of gas water heater is that it heats up quickly, is ready to use, is not controlled by water volume, even if it is used by multiple people, there is no need to wait, and the temperature is constant during use, which is very convenient and fast.

The disadvantage is that harmful gases will be produced due to insufficient combustion in the process of use, and there are potential safety hazards. 2.The advantage of electric water heaters is that they are not limited by the installation environment, and the electric water heaters sold on the market have a "safety anti-electric wall" device, which is clean and environmentally friendly.

The disadvantage is that the volume is large and occupies space, and it needs to be preheated before use, such as after washing, the remaining hot water in the inner tank of the water heater is not used up, and it will be slowly cooled and wasted. 2. Life comparison If the gas water heater is gas, it can generally be used for more than 5 years. Electric water heaters can be used for more than 4 years if the scale is cleaned on time.

From this point of view, electric water heaters and gas water heaters have their own merits, regardless of whether they are up or down. 3. Comparison of hot water production Gas water heaters mainly include 5 liters, 7 liters, 8 liters, 10 liters, etc. This figure refers to the amount of hot water produced when the water temperature is raised by 25 in 1 minute.

There are three types of electric water heaters: instantaneous, storage and quick-heating. The water output of instantaneous electric water heaters is affected by power, and the general water output of 7500 watts is equivalent to 5 liters of gas water heater. Storage type electric water heaters generally have 30 90 litres or larger, and this figure refers to the water capacity of the electric water heater.

4. Comparison of hot water temperature stability Gas water heater is heated rapidly, and the temperature is adjusted through the device, and the hot water will always maintain this temperature in the future. Instantaneous electric water heaters are divided into constant temperature type and mechanical type, the mechanical type is adjusted to the appropriate gear, the human body feels more comfortable, and the hot water in the future has been maintained at this temperature. The thermostatic electric water heater can accurately select the temperature of the outlet, such as 42, and the hot water will always maintain this temperature.

Hello! About the purchase of water heaters:

1. Select a type.

Water heaters are divided into electric water heaters and gas water heaters, gas water heaters are more economical, but they are noisy when used, and for some houses with large distances between kitchens and bathrooms, it is also a troublesome ...... to take pipes

2. Capacity selection.

To choose the size of the capacity according to the number of people in your family, if it is an electric water heater, a family of three can choose 60 liters, if there are many people, you must choose a larger one.

3. Brand selection.

It is recommended to choose Midea, Haier, Smith, Wanhe, etc.

First of all, look at the electric water heater, which is a water heater that heats the inner tank with electricity, so that the water temperature rises, which is divided into two types: water storage type and instant heating type.

Storage electric water heaters use electricity directly for heating, with less heat loss, and are not affected by water pressure and weather. The instantaneous electric water heater produces water quickly, is ready to use, and the amount of hot water is not limited, and it can continuously produce hot water, but the power is large and requires special wiring.

The gas water heater heats up quickly, is ready to use, can be used continuously and uninterruptedly, and has a low cost of use, but the water temperature may be hot and cold, and it is greatly affected by air pressure, water pressure, and floor height, and low air pressure may be difficult to start.

Q: How to choose a water heater.

Answer: Key points for choosing a water heater:

1. Energy choice;

At present, the domestic water heaters on the market can be divided into gas water heaters, electric water heaters, solar water heaters and air energy water heaters according to energy. Solar water heaters and air energy water heaters have not been widely used because of their shortcomings such as inconvenient installation, limited use area, and inability to guarantee hot water at all times. Urban homes are more suitable for choosing electric water heaters and gas water heaters.

2. Capacity selection.

Nowadays, many houses are designed with double bathrooms, and the householder will connect hot water pipes in the basin, laundry basin, vegetable basin and other places in order to use comfortably, if all the hot water valves are connected by the same water heater**, then the possibility of using hot water at the same time must be considered. Generally speaking, if the home has two bathrooms, is often used, and other hot water valves are installed, when choosing the capacity of the water heater, it is necessary to choose a slightly larger water heater to leave a margin.

3. Air source selection;

The gas source of gas water heater can be divided into natural gas, liquefied gas and artificial gas. If you choose a gas water heater that does not correspond to the gas source, it is easy to cause serious consequences, such as damage to the internal heat exchanger, and even carbon monoxide poisoning due to incomplete combustion. Before buying a gas water heater, it is essential to fully understand the gas source at home.

Some gas water heaters are only suitable for one kind of gas, and the gas water heater corresponding to the gas source cannot be mixed with other gas sources, so be sure to choose matching products according to the gas source.

4. Energy efficiency selection;

Energy consumption signs are affixed to the surface of all home appliances, and the same needs to be paid attention to when purchasing. Level 1 energy consumption is the highest level, which means that the energy conversion rate is the highest, that is, the most gas-saving (most energy-saving).

5. Brand selection;

Before deciding to buy a water heater, it's a good idea to look at the brand. The mainstream brands mainly include: Haier water heater, C yq annray, Vantage water heater (VATTI), Rinnai water heater (rinnai), Wanhe water heater (vanward) and so on.

6. Product selection;

Constant temperature is the main choice of the product, Anerrui water heater zero cold water series adopts a fully intelligent digital constant temperature system, so that the water temperature is not hot and cold, so that the bathing is more comfortable;

In fact, the internal design principle of the water heater, whether imported or domestic, is almost the same, as long as you choose a beautiful appearance when buying, it is acceptable.

There are four main types of water heaters on the market, gas water heaters, electric water heaters, solar water heaters, and air energy water heaters.
