Generally, how many milliliters of household water heater is good

It mainly depends on the use and disposable dosage. If it is only used for washing the face in the washbasin, 5 6 liters will do; If you want to use it for bathing, you have to choose more than 50 liters.

There are two kinds of electric water heaters, I don't know which one you want?! ~

One is a traditional tub type water heater!

One is an instantaneous electric water heater!

There are also solar water heaters and gas water heaters!

Let's talk about electricity!

Let's analyze it for you!

Big Bucket Electric Water Heater:

Advantages: 1: Easy to install.

2: Simple structure.

3: Cheap!

Disadvantages: 1: It is a waste of electricity, because it needs to be constantly replenished with cold water, so you can use half bile water after boiling it once!

2: The volume is relatively large and takes up space!

3: The service life is limited, for example, his inner tank is like a thermos gall, and it can't be repaired if it leaks!

Instantaneous electric water heater!

Advantages: 1: Ultra-small size, space-saving.

2: The pipeline is simple and easy to install.

3: Easy to use, hot when opened!

Disadvantages: 1 General home can not be safe! Generally, the power is around 7000-8500W.

Generally, the wire into the house is only 4 flat, and each flat is 2200w, in other words, without other electrical appliances, it can be 8800w at most!

2: In case of danger, there is definitely no help! Because the power is too much!

If you want to buy a barrel-type Haier, ao has a good one!

Haier has a long warranty period, of course, the quality goes without saying, there is a mechanical version below 1000 yuan! You can go to the big mall to see, 40L!

AO Smith: The inner tank is made of American gold silicon liners, the quality is also good, and there is a mechanical version of 40L below 1000 yuan!

I'm so tired that I don't write much, and I want to know what can be directed to me for a Q&A!

Hope my answer will be helpful to you!

Original answer, declined**)))).

Choose the right capacity size based on your family members and the size of your house.

For example, if you have a family of 3 or 4 people and two bathrooms, then choosing a 16-liter gas water heater is a must.

If the capacity is small, it will lead to the phenomenon of small water output, slow water output and insufficient hot water.

The rated volume is 30 40 liters electric water heater, suitable for 3 4 people continuous bathing use.

The 40 50 liter electric water heater is suitable for 4 to 5 people for continuous bathing.

The 70 90 liter electric water heater is suitable for 5 to 6 people for continuous bathing.

How to buy an electric water heater

1. Select capacity.

The choice of capacity is mainly determined by the number of people in the household and the amount of hot water used. Usually, if one person is taking a bath, you can buy an electric water heater with a capacity of 30-40 liters; 2 to 3 people should buy a 40-50 liter electric water heater for continuous bathing; If 3 to 5 people are used for continuous bathing, a 70-100 liter electric water heater should be purchased.

2. Look at the inner tank.

The inner tank is one of the important parts of the electric water heater, which is equivalent to its "heart", and the function and quality of the inner tank directly depend on the service time of the storage electric water heater. At present, the focus of the first electric water heater liner is 3 kinds: galvanized liner, stainless steel liner, and enamel liner.

Considering the aspects of anti-corrosion, heat retention, and service life, the enamel liner has more advantages.

3. Check security.

Electric water heaters are electrical products, and their safety directly determines people's personal safety. Generally, storage electric water heaters have four conventional protections: grounding protection, anti-dry boiling, anti-high temperature, and anti-pressure device. Now people's awareness of electricity still needs to be strengthened, and there are often dangerous accidents of electric water heater leakage, so leakage protection is quite important.

So how many liters of water heater is suitable for your needs? Listen to what a water heater shopping guide with many years of experience has to say.

How large capacity water heater to buy depends mainly on how many people in the family use it.

At present, there are three types of conventional water heaters, gas water heaters, storage electric water heaters, and solar water heaters.

The outdoor unit of the solar water heater is hung on the roof of the building, and it is really something that depends on the sky to eat. All year round, there is nothing to say about hot water when it is turned on in summer, but it depends on the weather in spring and autumn, if it is cloudy and rainy.

Therefore, now homes are generally installed with electric water heaters and gas water heaters.

First of all, the capacity of the electric water heater, after the installation of the big bucket on the wall, how many liters of water can be filled in it.

The number of liters of a gas water heater indicates how much hot water can be heated per minute with a 25° increase in temperature.

In layman's terms, it is

The inlet water temperature is 10, then when the outlet water temperature is 35, 10L of water flows out every minute, which means that the water heater is 10L

If you want an electric water heater, you can choose according to the amount of water consumed by about 20-30L per person. That is, a family of three chooses an electric water heater of 60-90L. If you choose a smaller one, two people will need to wait for hot water after taking a shower and the third person will need to wait for hot water, which will take about 30-60 minutes to heat up.

The gas water heater is generally 12-13L for a family of three, in fact, as long as there are not multiple faucets at the same time, a few more people can use 13L. The reason is very simple, the gas water heater is ready to heat and use, if one person takes a bath and one person washes dishes in the kitchen, the equivalent of a 12L water heater becomes two 6L water output.

Reference diagram for the selection of the liters of the gas water heater.

So is the above ** correct in actual practice?

For this reason, when I got a haircut at the barber shop in the community, I asked the boss how big a liter of water heater he had installed, and he said that he installed a Rinnai 13L, plus a small kitchen treasure.

How to calculate if you install a bathtub at home?

If you want to make the most of your bathtub function, give priority to an air water heater.

If you have solar energy, you can do it in summer, but some owners say that 100L works well for electric water heaters, and some say that 100L doesn't work at all.

I don't think the utilization rate of the bathtub is high, if you really have to take a bath every day, you have to buy a large number of liters.

Usually the electric water heater below 15 liters is used in the kitchen to wash dishes, vegetables or washing, if it is a water heater used for bathing, you should choose a capacity greater than 40 liters, a person is best to choose a capacity of 40 to 50 liters, two people are recommended to choose 50 to 60 liters, a family of three can choose 80 to 100 liters, more than three people can choose more than 120 liters and so on.

How to choose depends on your actual situation.

5 10L water heater is generally used for washing dishes, washing vegetables in the kitchen or washing face and brushing teeth in the washroom.

The water heater used for bathing should choose a capacity of more than 40L, and the water heater with a capacity of 40 or 50L should be used by 1 person. For 2 people, a water heater with a capacity of 50 to 60L is suitable. A family of 3 is suitable for a water heater with a capacity of 80 100 liters.

Families with more than 3 people are suitable for water heaters of 120L or more. If you are used to bathing in a bathtub, it is best to choose a water heater above 150L.

It should be determined according to the water consumption of the family, such as the number of family members, water habits, the number of liters of household electric water heaters is 50L, 60L, 80L, 100L, etc., for ordinary families of three, you can choose water heaters above 60L.

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 size and more powerful than the storage electric water heater, so the heating speed is indeed faster than that of the storage electric water heater;

However, it can not achieve instant heating in spring and autumn, and it needs to be preheated, that is, it needs to wait, while the dual-mode electric water heater can be used in the three seasons of spring, summer and autumn, and it can be heated when it is turned on.

Generally, choose a 60-liter or 80-liter water heater for household electric water heaters.

The liters of a domestic water heater should be determined according to the amount of water used by the household. Such as the number of family members and water consumption habits. For an average family of three, you can choose a water heater of more than 60 liters, and a family of four generally chooses an 80-liter water heater. Good Dan.

Ways to buy a water heater:

1. Capacity. When buying a storage electric water heater, the first thing to do is to decide the capacity of the water heater. The choice of water heater capacity mainly depends on factors such as household size and hot water usage.

Generally speaking, if 1 person is used for bathing, you can choose an electric water heater with a volume of 30-40 liters; 2-3 people should buy a 40-50 liter electric water heater for continuous bathing; If 3-5 people bathe continuously, you need to buy a 70-100 liter electric water heater. In addition, the larger capacity of the external size is generally larger, therefore, it is also necessary to consider the size of the installation space, the general storage water heater is a round barrel body.

2. The inner tank of the electric water heater.

The inner tank is the most critical part of the storage electric water heater, which can be said to be its "heart", and the performance and quality of the inner tank directly determine the service life of the storage electric water heater. At present, there are three main types of electric water heater liners on the market: galvanized liners, stainless steel liners, and enamel liners.

From the aspects of anti-corrosion, heat retention, service life, etc., the enamel liner is the best.

3. The safety of electric water heaters.

As an electrical product, the safety of electric water heater directly determines the personal safety of users. At present, our electricity environment is not very ideal, and there are often accidents caused by electric water heater leakage and injury, and the leakage protection of electric water heater is extremely important. At present, the anti-electric wall technology is a relatively reliable anti-leakage protection measure, and this technology has been included in the new national standard for electric water heaters, among which the built-in anti-electric wall patent is owned by Haier, and the external anti-electric wall patent is owned by Jiangnan Electric.

When purchasing, check whether the product has safety technologies such as electric walls.

4. Choose energy-saving products.

The energy efficiency level of storage electric water heater is divided into 1-5 grades, of which level 1 is the highest, level 2 is second, and level 5 is the lowest, which is the energy efficiency limit value and the threshold for market access, and products below level 5 will not be sold in the market. <>

60-100l。

It has many selection factors, such as: number of family members, household usage habits, use in different regions, etc. When we choose, it is best to choose a liter that is slightly larger than the actual water consumption, so as to avoid the problem of insufficient water in the future, especially storage type electric water heaters.

Generally speaking, its liters are 50L, 60L, 80L, 100L, etc., if you are a family of three, it is recommended to choose 60L, if you are a family of four, it is recommended to choose 80L-100L electric water heater.

Pay attention to buying an electric water heater for your homeMatters:

Although electric water heaters save electricity and the water temperature is stable, traditional electric water heaters still have hidden dangers of leakage in terms of safety. Therefore, it is best to go to a regular store to buy products with guaranteed quality, so that even if there is a failure, it can be repaired in time! Or choose a new generation of magnetic energy water heaters that are safe and leak-free.

Each type of electric water heater has its own features and disadvantages. We then choose the right household electric water heater according to our own needs, so that it will be more convenient and comfortable to use!

The purchase of gas water heaters has nothing to do with the size of the family. However, it has to do with the water points at home such as toilets, wash basins, balcony sinks, etc., and the distance between the water points. Generally, it is necessary to consider whether it is required to "use multiple water points at the same time", and choose 10L for one bathroom; Choose 12L for a bathroom and a kitchen; Two bathrooms and a kitchen are available for 16L; For 4 bathrooms, choose 24L.

Answer: Hello electric water heaters are generally water storage type, when purchasing, you need to look at the size of the water tank capacity, generally 60L, 80L, 100L, etc., when we buy, we need to choose 1-2 people reasonably according to the number of people: if the home is using an ordinary shower, generally 50-60L is about the same; Large showers use 60-70l. In the case of 3 people:

60-80L electric water heater for ordinary showers; Large showers use 80-100L. More than 3 people: 80-100L for ordinary showers; Use large showers of 100 liters or more.

If you use a bathtub at home, then you must choose more than 100L; If you also need hot water from an electric water heater in your kitchen, you should choose an electric water heater with a larger capacity as appropriate
