9 electric heaters, several circuits are required for electricity distribution

The simplest and most common is that each electric heater corresponds to a separate circuit.

A little more complicated to consider, it depends on whether you need several electric heaters to be turned on and powered on at the same time. The method of synchronization is very simple, and several units need to be synchronized to go through a loop. But in this case, you need to make sure that the stringing specifications reach a sufficient current carrying capacity.

Take, for example, the most expensive electric heater in Enstor, Finland. Each electric heater is a fixed power intermittent working constant temperature, that is, when the temperature of your room reaches the expected value you set, it will automatically turn off the power and save energy; If the temperature drops below your setting, the room will be automatically heated with electricity to keep the room at a constant temperature. In other words, this high-end electric heater is different from the low-end electric heater that has some power levels regardless of the cold and heating conditions of the room, and the working power of this high-end electric heater is constant, and it can be calculated very concisely when wiring the power supply.

For example, the minimum power of the Ensto electric heater is 500 watts, the maximum is 2000 watts, if the power cord embedded in the wall is 4 squares, and your 9 electric heaters are 2000 watts, then you want to use a circuit belt is definitely not possible, the current has already exceeded. If all 9 of you are 500 watts, that's okay.

Depending on maintenance and heating needs. If 9 electric heaters are distributed in one room, one circuit can be distributed, but if they are distributed in 3 rooms, there are no three circuits. Of course, in order to facilitate maintenance and not affect the heating, 9 circuits can also be arranged.

An electric heating arrangement requires about the entire circuit, so that it can be controlled separately and is not afraid of damage and repair.

It depends on how many rooms you are in, and you need a circuit in each room.

It is better to deploy 3 channels of power for 3-phase 4-wire power supply.

According to the demand factor k1 of each circuit load, and the simultaneous coefficient k2 of the 9 circuit loads, the total calculated load is calculated, and the total tank capacity is selected. Total capacity p=k1 k2 9 9kw

Depending on the electricity consumption, please refer to the following scheme.

1. There is a lot of electricity in the kitchen, a special circuit for the kitchen is set up, and a leakage protector is used, which can also include kitchen lighting;

2. Special circuit for air conditioner;

3. Lighting circuit, if it is a multi-storey building, two lighting channels can be arranged.

4. Other wall socket circuits, (leakage protectors should be connected) 5. If there are courtyards, garages, etc., their electricity should be arranged separately.

Concealed pipe laying, pay attention to the location of the distribution box, sockets and distribution boxes away from places with water, away from heating pipes. It is best to ask an electrician to help with the wiring, and do not connect it yourself. Also pay attention to the layout of the room, such as the place where you want to put the TV, the place where you put the refrigerator to arrange the socket, these ground clearance 300mm-500mm, when the switch is arranged, it is generally convenient.

Of course, each room leaves the air conditioning socket wiring, and the socket is reserved in the appropriate position, and what is not used at this time may not be used in the future. Cabling is as safe as possible.

In order to be beautiful and easy to inspect and replace, it is generally used to bury slotted wires and lay hidden pipes, and it is necessary in the wiring process.

Follow the principle of "live wire into the switch, zero line into the lamp head".

The electrical stage is a very important part of the house decoration, if the random transformation may cause great safety hazards, so it must be completed cautiously. The selection and wiring of wires are extremely demanding.

(1) It is best to have no connector in the middle of the home wiring. There must be connectors that should be firmly in contact and wrapped with insulating tape, or with a porcelain junction box. It is forbidden to use medical tape instead of electrical tape to wrap joints.

2) The connection between the wire and the switch, knife switch, fuse box, lamp head, etc. should be firm and reliable, and the contact should be good. The multi-strand soft copper wire joints should be twisted together and then placed under the joint screw gasket to prevent the thin strands from spreading out and hitting the other joint and causing a short circuit.

3) The household wiring shall not be directly laid on the flammable building materials, and porcelain beads or porcelain clips must be used if the wiring is needed on the wood; Porcelain sleeves must be used to cross the planks. Do not use flammable plastics and other flammable materials as decorative materials.

4) Although the grounding or neutral wire is not charged under normal circumstances, if there is leakage after the wire is broken, the electrical shell will be electrified; In case of a short circuit, the ground wire will also pass through a high current. For the sake of safety, the specification of the grounding (zero) wire should not be less than the phase wire, and no switch or fuse should be installed on it, and there should be no joint.

5) The grounding wire shall not be connected to the ground wire of the water pipe, gas pipe and ** line; It must also not be connected to the lightning cable.

6) All switches, switches, and fuses must have covers. Bakelite covers must be replaced if they are aged or incomplete. Those who are dirty and damp must be wiped clean after the power is off before use.

7) Do not drag and drop the power cord on the ground to prevent the power cord from tripping people and to prevent damage to the insulation.

Your electric heating voltage should be 220V, if you can lead to three-phase electricity, the load is evenly divided into about 12kw per phase, 4 square copper wire should be just right, it depends on your use, if the radiator is fully open, it is recommended to replace it with 6 square copper wire, if the usage rate is about 70%, the original line should be able to meet (provided that there are no other high-power electrical appliances at home). If you press the switch, you must choose one with leakage protection, which will be safer. Recommended:

DZ47LE-100, leakage current 30mA. The wiring method is recommended to use the method described above.

4 square millimeters of wires, series connection is not enough, copper core wires are not enough. The total load is ah, the line on the drawing is not clear, it is recommended that you take a wire circuit for the electric heater in each room, and control the electric heater by a corresponding air switch, or a circuit of a similar electric heater, but the power of the total electric heater is not too large, and each circuit is laid with a square millimeter or 4 square millimeters of copper core wire, and then you can determine the specification of the wire according to the actual situation. This kind of wiring is safer, convenient for maintenance in the event of a failure during future use, radioactive wiring is better, but there will be more wires to be used, home use, more wires are still more practical, safety is important.

If you use a three-phase meter, you can buy a three-phase meter, the working current of the electric heater is about 60A, plus other electrical appliances at home, you can calculate the capacity of the meter yourself. The choice of air switch should also be appropriate.

The longest length of each circuit of the floor heating coil should not exceed 120 meters, and about 80 meters is the most suitable, and the length difference between each circuit should not exceed 10 meters.

First, the energy saving is outstanding.

Floor heating is a radiant heating method, which has higher thermal efficiency than convection heating, and floor heating can concentrate heat in the height of the human body; Small heat loss during transfer; At the same time, users can also flexibly adjust according to their own use to further effectively save energy.

2. Scientific, healthy, comfortable and has a health care effect.

The full name of floor heating is low-temperature radiant floor heating, which is by far the most comfortable heating method for human beings, the indoor surface temperature is uniform, and the room temperature gradually decreases from bottom to top, giving people a comfortable feeling of warm feet and cold heads.

3. Floor heating does not take up space, and the use of the living room is more flexible.

Floor heating is a concealed project, there is no radiator and branch pipe to occupy space, from the side to increase the use of the living area, can expand part of the indoor space.

Fourth, the service life is relatively long.

The plastic pipes or heating cables used in floor heating are buried in the ground, with good stability, no corrosion, no human damage, and the service life is synchronized with the building. The price reduces the user's maintenance cost.

The disadvantages of underfloor heating are:

1. The rehabilitation period is short.

When the floor heating system is in operation for 2 to 4 years, the floor heating pipeline produces scale, which needs to be cleaned by professional equipment, otherwise it will directly affect the heating effect.

2. The use of toilets is restricted.

Due to the complexity of the heating pipes of floor heating, for the sake of waterproofing, the floor heating coil should be waterproof before and after, due to the small laying range of the bathroom (such as to reserve the toilet, bathtub, drain, etc.), the room temperature often does not reach the heating standard, and it needs to be supplemented by radiators.

Third, it is not easy to maintain.

Floor heating is a concealed project, and materials with good pressure resistance, temperature resistance, corrosion resistance, and good thermal stability should be selected for decoration. It is not convenient for secondary decoration, because the pipeline is laid underground, and when the ground is transformed, it is easy to damage the underground pipeline. And it is not suitable to lay decorations on the floor, which is easy to affect the heat dissipation effect.

There is no scientific basis for the six hazards of floor heating, strictly speaking, the research that can prove that there is a direct relationship between floor heating and disease must go through randomized, controlled, double-blind, multi-center clinical trials, and be certified by authoritative medical institutions, but at present, there is no conclusive research evidence.

To ensure that the temperature of the floor heating reaches a comfortable effect, the floor heating pipes should be laid in strict accordance with the standards, such as 16 pipe spacing should be equal to 150mm, 20 pipe spacing 200mm pipe layout, the use of hollow pipe layout, so that the temperature is uniform. The floor heating pipes are designed according to the circuit, according to a circuit of 80 meters to 100 meters, the temperature is controlled by the electric heating actuator alone, and the temperature control panel of each functional area is used to accurately control the temperature of each area.

When installing, a layer of insulation mat is laid on the ground, and then a layer of aluminum foil reflective film is laid to prevent the heat from running downstairs. In addition, a layer of barbed wire must be erected on the reflective film, and when the cement is covered, this layer of barbed wire acts as a reinforcing bar. Then, according to the design drawings of the heating company, the heating water pipes are connected to each room, and the heating water pipes are evenly distributed in every corner of the room by rotating circles, and the spacing around the pipes is specified and cannot be too wide or too narrow.

It is known that the room area s=a*b and the spacing of the floor heating pipe is 20, and the length of the floor heating pipe is found l l=a 20*b=s 20, which is roughly like this, which is related to the actual laying method.

First of all, according to the type of room to divide the heating area, such as the living room, dining room, aisle can be divided into a region to place a thermostat independent control, the area is divided into a good area (preferably a floor plan), the place that does not need to do floor heating is removed, such as cabinets, toilets, basins, fixed wardrobes below these places can not do floor heating, according to the heating area and heating area to calculate the pipe length, water collector circuit and thermostat, Shanghai side of the floor heating pipe length is calculated according to each square 6 meters, the pipe core distance is 20 cm, Close to the balcony place, the bathroom is laid to 15 cm, the water separator is calculated according to the area and the length of the pipe, the general loop pipe length can not exceed 120 meters should be controlled within 90 meters, so 90 meters for a circuit of about 15 square a circuit, the thermostat is a heating area a thermostat, the main pipeline is calculated according to the length of the boiler connected to the water separator, the pressure difference bypass one, if it is multi-layer, it should be equipped with a floor heating return pump, as for some valves and valves to be determined according to the situation.

This is not necessarily, according to the area pattern of your room, and the habits of each installer are different, Rising Sun suggests that this circuit is as few as possible, so try to be as little as possible when installing.

The floor area is multiplied by the floor heating area and the water separator is 17 square meters for a circuit.

Generally, one room is one way, if the master bedroom area is large, you can use two roads, two ways in the living room, and five to six roads in the case of three bedrooms and two living rooms. Generally, one road should not exceed 15 square meters.

It can be seen that you are a person with a heart, but the circuit diagram of the electric heater is very simple, and most of them are purchased. Generally, manufacturers of electric heaters do not produce circuit diagrams. But there is one thing,The principle is very simple,You can find a TV repair to ask for it。

The problem is not comprehensive, are you asking for or supplying!

Hey, there are so many people who want to get something for nothing.

The total air opening is a switch with leakage protection, and it is a whole, how can it be said that it accounts for four, it is not right. The main switch controls the eight single switches at the back.
