What is good for hot water at home, and what water heater is good for bathing at home

At present, China's water heaters can be divided into four types: gas water heaters, electric water heaters, instantaneous water heaters and solar water heaters according to the energy used.

Advantages and disadvantages of various types of water heaters:

1. Gas water heater.

The flow rate is large and the temperature rises quickly; Less limescale. It is extremely unsafe to use, toxic gases will be discharged during use, accidents are frequent, and it is inevitable to spill even if it is a strong exhaust type. The starting water pressure is high, and even the users who live in the building cannot start if they do not install the booster pump; The installation is inconvenient, so it is necessary to make holes in the wall, arrange air fans, etc.; Due to non-compliance with environmental protection principles and other reasons, it was finally banned by the people of all countries through legislation and conscious actions.

2. Storage type electric water heater.

The power is small, ordinary families can be directly installed and used, and the power can reach a large flow of hot water for a long time; Adaptable to any weather changes. It is large in size, easy to form scale, and wastes a lot of electricity, often wasting a lot of electricity to increase the temperature of a whole bucket of water and not use it up. With the water temperature increasing for a longer period of time and the family's indefinite bathing time, electricity is often needed for hours to meet the family's needs.

3. Instantaneous electric water heater.

Small size, fast heating, less limescale, can adapt to any weather changes by increasing the power. Its hot water output is small, the power is large, and a special line needs to be installed. If 3 litres per minute is required and the temperature of the water is 5 degrees, at least it is required.

If the water output per minute is 5 long, the water temperature is 40 degrees, when the water inlet temperature is 10 degrees, at least it is required; At least when the inlet water temperature is 5 degrees, it is required. The cost of its dedicated line is often several times the cost of an electric water heater.

4. Isothermal electric water heater.

Small size, fast heating, less scale, only need to be connected to water and electricity, can be used directly; When a large amount of hot water is required, it can be obtained by powering on for only a few minutes, adapting to any weather changes, and has the advantages of instantaneous electric water heaters and storage electric water heaters. Ordinary households can be installed and used directly. If you forget about the power outage, when the water temperature reaches 80 degrees, the power will be automatically cut off and kept warm.

Electric water heaters, or gas water heaters, about the price of about 1500, Midea, Haier, Smith, Ariston electric water heaters Wanhe gas water heaters, don't buy solar energy because the health of solar energy is not up to standard, don't buy air energy technology is not mature.

Hello pro 1Haier water heater, not bad 2When purchasing, you should look at the volume model of the water heater, which refers to the amount of hot water that can raise the water temperature to 25 degrees in one minute.

It depends on the amount of hot water used in the household. The choice of installation site, there are vertical and mandatory horizontal water heaters, but generally vertical water heaters, horizontal installation is only a small space in order to hide the beauty, ** more expensive, not easy to maintain. Showers and baths have different requirements for the function of the water heater, one is the precise control of temperature, and the other is the achievement of thermal efficiency indicators.

The water heaters suitable for home use are as follows:

1. Solar water heater. Solar water heaters are the most primitive and environmentally friendly ecological heating methods, but they are greatly affected by the weather, and cloudy or rainy days will lead to a decrease in the water supply rate of hot water; It is also limited by location and requires a flatter installation position. Nowadays, most homes use a combination of solar and electric water heaters.

2. Gas water heater. Gas water heaters use natural gas or coal gas as raw materials, and the advantage is that they are heated immediately and do not need to wait. When purchasing, it is recommended to choose a gas water heater with an anti-carbon monoxide poisoning system.

3. Air energy water heater. The air energy water heater absorbs the low-temperature heat in the air, vaporizes the fluorine medium, and then pressurizes and heats up through the compressor compression, and then converts the water to heat through the heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature. Its advantages are energy-saving, environmental protection, and power saving in later use.

4. Electric water heater. Electric water heater uses electricity as an energy source for heating, divided into water storage type and instantaneous type, the advantage is that it is safer, simple to install, and more convenient to use, but it has higher requirements for the inner tank.

1. Gas water heater.

Advantages: fast heating (instant washing), small installation footprint.

Disadvantages: poor environmental protection and safety, hollow wall can not be installed normally, high installation requirements, unsightly, unstable water temperature (water pressure fluctuations), limited use (water, gas, electricity, smoke emissions, etc.).

2) Storage electric water heater.

Advantages: convenient, environmentally friendly, comfortable, installation requirements are not high, suitable for mass family use.

Disadvantages: large volume, unsafe installation on the wall, hollow wall can not be installed normally, unsightly, occupies space, and the continuous bathing time is limited.

3. Instantaneous electric water heater.

Advantages: fast heating, small shape does not take up space.

Disadvantages: the installation of the wall is not beautiful, the purchase cost is high, the heating power is large, the installation environment has high requirements, the water output is small (the northern region or low temperature weather can not be bathed), the water temperature is unstable, the technology and process are not very mature, and the failure rate is high.

4) Solar water heater.

Advantages: safety, energy saving, environmental protection.

Disadvantages: outdoor roof installation, in case of strong wind, typhoon, easy to fall, very dangerous, high purchase cost, complex installation and large area of land, use affected by the weather and large waste of water (to drain the cold water in the pipe when using), maintenance is troublesome and maintenance cost is high (solar water heater is installed outdoors, so it is more difficult to maintain than electric water heaters and gas water heaters).

5) Air energy heat pump water heater.

Advantages: thermal efficiency, energy saving, water supply can be realized.

Disadvantages: Outdoor machine wall installation, easy to fall unsafe, large volume indoor unit occupies space, not beautiful, high purchase cost, complex installation, immature technology, noise. 6

6) Integrated water heater.

Advantages: The appearance is the same as the bathroom cabinet, no need to hang on the wall, safe, beautiful, space-saving, simple installation, convenient, environmentally friendly, comfortable, the installation requirements are not high, suitable for public family use. You can take a bath, wash your hands and wash your vegetables.

It integrates five major functions: hot water for bathing, hot water for washing, wash basin, locker and vanity mirror.

Disadvantages: Continuous bathing time is limited.

There are many types of household water heaters, and you can choose the right type according to your actual needs and usage habits, mainly including the following:1Storage Water Heaters:

Storage water heater is one of the most common types on the market today, which heats the water in the tank to produce hot water. The advantage is that it is relatively low and easy to use, and the disadvantage is that it needs to occupy a certain amount of space and is a waste of energy. 2.

Instantaneous water heaters: Instantaneous water heaters do not require a storage tank, and the water flows through the heater to get hot water, which can be turned on and used when needed. The advantage is that there is no need for preheating, which saves energy, and the disadvantage is that it is relatively high and the water temperature is unstable.

3.Solar water heaters: Solar water heaters use solar energy for heating, without the need for electricity or gas, and are an environmentally friendly, energy-saving option.

The advantage is that the cost of use is low, environmental protection, and the disadvantage is that when the weather is bad, the hot water will be affected by a certain amount of sales. 4.Gas Water Heater:

Gas water heaters heat water by burning gas, the water temperature is stable, and it is easy to use. The advantage is that the hot water is stable and the energy consumption is low, and the disadvantage is that gas needs to be used and ventilation needs to be maintained. You need to choose the right water heater according to your actual situation, such as the number of family members, frequency of use, water consumption, economic strength, place of use and other factors need to be considered.

At the same time, it is recommended to choose products with well-known brands and guaranteed quality to ensure safe and reliable use.
