I want to buy a tankless water heater, but I don t know what to do with the square millimeter line i

Very simply, the capacity of the meter can be viewed on the meter; The size of the power cord can also be measured by yourself, the square power cord, the diameter of the wire (bare wire) inside is millimeters, the diameter of the power cord of 4 square is millimeters, and the diameter of 6 square meters is millimeters. If the main line of the power cord is less than 4 square meters, do not consider buying an instantaneous electric water heater, you can use a gas water heater or a storage electric water heater, and it is best to install a solar water heater if possible. If the main line of the power cord is 6 square or thicker, you can consider purchasing an instantaneous electric water heater.

The purchase of instantaneous electric heaters depends on your geographical location, the southern region can buy a small power (more than 5000 watts), and the northern region must buy a large power (more than 7000 watts), otherwise the amount of hot water in winter is too small or the water temperature is not enough.

The advantage of instantaneous water heater is that it heats up quickly, but it consumes a lot of electricity If you have 4 people in your family to take a bath, you need at least 5 kWh of electricity once, so it is recommended that you buy an air energy water heater (the most energy-saving, but it depends on whether there are buried pipes on the balcony when you decorate your home) and electric water heaters. If it's in Guangzhou, I sell it here.

The quality of the instantaneous type is not yet able to catch up with the water storage type. It feels like it's easy to burn out of the old age.

There is nothing to do with the 4 square copper wire, don't worry about anything else, just connect the socket directly

Summary. Pro, it depends on how much power the water heater is. If it is an electric water heater of about 3 kilowatts, it usually uses 4 square meters of wires, and if the power is higher, the more wires will be used.

2. If a 1500-watt electric water heater is used, the wires used are square meters, so there is no problem with the power load. When installing an electric heater, the electrician will advise you on which wire is better.

Pro, it depends on how much power the water heater is. If it is a 3 kilowatt electric pre-infiltration water heater, it usually uses 4 square meters of wires, and if the power is large, the more wires will be used. 2. If a 1500-watt electric water heater is used, the wires used are square meters, so there is no problem with the power load.

When installing an electric heater, the electrician will be sensitive to advise you on which wire is better.

Smart instantaneous water heaters, which require thick wires.

Square pro. Cooking at home, bathing consumes a lot of electricity, is 2,5 enough?

Enough pro. You take a bath, and you're not alone and run out of water.

He'll heat it up when he's using it.

<> "There are many types of electric water heaters on the market today, and instantaneous electric water heaters are loved by many users. So how many square wires do instantaneous electric water heaters use?

1. 8000w instantaneous electric water heater with a few square wires

Just use a square copper core wire. This kind of water heater uses direct heating to work poorly, because it has a groove plate inside, so when the cold water passes through the groove plate, it will be directly transferred to the electric heating element, and the electric heating element belongs to the special heating accessories, so it can quickly form a heating working state.

2. How to use instantaneous electric water heater

1. The water valve of the instantaneous electric water heater should be opened first, and the power of the water heater should be turned on after the water pressure is completely stable, and then the water temperature can be set. This can effectively avoid the problem of dry heating of the electric water heater and better protect the internal heating pipes. It can be adjusted by using the control panel on the screen, which can be raised or lowered, and can be used after the adjustment is ready.

3. Advantages and disadvantages of instantaneous electric water heaters

Advantages: 1. The important advantage of this electric water heater is that it is very convenient to use, it is immediately heated up, and it is not necessary to preheat it in advance, and at the same time, you can put as much water as you want, which can really save water and electricity.

2. It is also particularly environmentally friendly, so it is very safe to use, and it has a smooth over-temperature power-off function.

Disadvantages: 1. Its power will be very large, so the requirements for the line are very high, and if you want to install this electric water heater indoors, the requirements for the power cord will be very strict.

2. In addition, the requirements for installing this kind of water heater will also be very high, and a separate line should be set up.

It can be used for sure, but because the power of the water heater is relatively high, the current passing through it at the same time will be relatively large, and if the current is large, there will be heat generation, and if it is used for a long time and many times, it may cause the same sex to burn out, so it can be used, but pay attention to the frequency of use.

Square copper wire, with 6000 watts of instantaneous water heater is not allowed, because there are great safety hazards. The minimum requirement for the use of a 6kw instantaneous water heater is to use 4 square copper wires. The safest wire is to use six squares.

I have a 6kw instantaneous water heater at home, with square copper wires, which can be used normally.

But if conditions permit, it is safer to use a 4 square or 6 square line.

It can definitely be used. Because the bearing strength of the square meter copper wire is very high, it can also be used in a 6 kilowatt water heater.

Summary. The power of the instant electric water heater is generally between 2 kilowatts and 3 kilowatts, so it is necessary to use wires that meet the requirements. Generally speaking, it is recommended to use square millimeter wires for the use of fast heating electric water heaters, which can meet the safety requirements of current transmission and wires.

However, the specific size of the wire needs to be determined according to the actual situation, such as the length of the wire, the load of the wire and other factors will affect the choice of wire. If you are unsure of the size of wire you should use, it is advisable to consult a professional electrician or consult the relevant electrical manufacturer.

I'm going to renovate my house and need to remodel the wires.

The power of the instant electric water heater is generally between 2 kilowatts and 3 kilowatts, so it is necessary to use wires that meet the requirements. Generally speaking, it is recommended to use square millimeter wires for the wires of the instant thermoelectric water heater, which can meet the safety requirements of the current transmission and wires. However, the size of the wire used by the backup body needs to be determined according to the actual situation, such as the length of the wire, the load of the wire and other factors will affect the choice of electrical and disadvantageous wire.

If you are unsure of the size of wire you should use, it is advisable to consult a professional electrician or consult the relevant electrical manufacturer.
