How to connect an electric boiler heating ?

advantage and scope of products

electrocoppers most often used when installing heating in the country and in a private home.This is due to the fact that the equipment cost is low and thus it can be set independently, without calling the master.

The main advantages of electric boilers emit:

• products are safe (the design does not include the presence of an open flame or flammable fuels);
• water heaters may be in the open position up to six months, with no harm to your health (important for summer cottages and country houses, which are rarely visited);
• equipment dimensions are relatively small, so you can place it in any room;
• today there is a huge variety of electric boilers of different capacities, a method of installing and operating principle;
• by heating the water there is no soot, dangerous for both man and the environment.

safety rules

Before we get to the main part of the heating installation, it would be desirable to pay attention to the safety of electrical work.

First , connect an electric boiler heating must be switched off at the power.

Second , it is necessary to establish a certain distance from other objects, namely:

• between the housing and the walls should be at least 5 cm of free space;
• front cover should be accessible for maintenance, 70 cm of free space is enough;
• distance to the ceiling is not less than 80 cm;
• distance to floor at least 50 cm (if the electric boiler is suspended type);
• distance to the next pipe is not less than 50 cm.

Third , should be a three-phase network (380 B) to reduce the current load on the wiring.When using a single-phase network to a powerful boiler wiring can not survive, so that its spontaneous ignition occurs and short circuiting.

Fourth , all wiring connections should be sealed and protected from water.Water entering a contact can occur when damage to the pipeline (for example, burst coupling, supplied to the unit) and condensate runoff from the ceiling (in unheated rooms).It is also recommended to protect the flexi hose cable, or from self-extinguishing cable channel.When wiring fire these products will prevent flame spread.

Electrical installation scheme

So, to bring to your attention some typical circuits connecting electric boiler in the house with his own hands:

As you can see, the projects are fairly simple and consists of the water heater, the shipping line (tubes), the circulation pump and radiators.Your task - to properly connect all the elements together, and then make a power-up.

basic process

Set unit

First we need to establish an electric kettle in the room.As we have said, the unit can be wall-mounted and floor.In the first case, the bundle includes a special stand, which is produced and "landing".

To hang on the wall of the boiler, it is necessary to prepare the anchor with dowel and drill with a suitable drill.First, mark up the wall with a tape and a marker.The holes should be placed perfectly straight in the horizontal plane.Next, drill the marked place, hammering them dowel and screw-anchor.Once the anchor is firmly zasyadet inside the wall, you can hang the electric boiler.

draw your attention to the fact that the electric boiler must be installed perfectly flat and horizontal and vertical plane.Any misalignment can affect the performance and service life of equipment.

Summing wiring

Since electric water heater has a large capacity, it is not necessary to connect from the outlet, and directly from the mains.To do this, the junction box in a separate room is necessary to bring a line extending to the point of connection of the boiler.Better to use cabling hide a way asin this case the line will be protected from mechanical damage and at the same time the appearance of the premises does not spoil.

should be noted that for the boiler power is necessary to use a large section of cable that can withstand the relatively high current loads.About how to properly carry out the calculation of the cable cross-section, we discussed in the corresponding article, which strongly recommend that you read.

So draw your attention to the fact that small-capacity water heaters (up to 7 kW) can be connected to single-phase network, which is often found in the Khrushchev and apartments of the old model.Well, the last nuance, at this stage, which you should know - electric boilers up to 3.5 kW can be operated from the electrical outlet, and not on a separate line from the junction box.Low-power boilers are ideal for connection in the apartment, because in this case, the wiring, as a rule, single-phase and make a new cable wiring is not always a viable solution.

Install protective equipment

When all input wires are connected to the electric boiler will be necessary to further protect its circuit breaker and RCD installed on the main board.Purpose of the first device - to protect equipment from short circuit and overload wiring.Connecting the electric boiler through the RCD will protect you from leakage currents.

also recommended to connect the voltage regulator, becauseEven small surges can bring the unit out of operation.

That must be grounded electric boiler, I think, not worth talking about.The main requirement is that the ground wire was carried directly to the body of the bus hardware.

produce start

When all wiring elements are connected, check all connection points.Bare contacts should not be, in fact, as the damaged insulation.

is also necessary to check all joints, valves and pipe joints.Only after a quality inspection of the heating system, you can continue to launch it.First, open the gate to let down equipment, then turn on the electric boiler.

Note the operation temperature and pressure sensors.Nominal values ​​are specified in the instructions that are provided.When obvious deviations better call the master.

also provide to you a clear example of installation work:

On what can you save?

Electric heating is quite expensive compared to gas.To make it cost-effective, consider the following tips:

1. Purchase a two-tariff electricity meter and turn on the heating at night.Day usually all at work and the need for operation of the boiler is absent.Better a good heat their premises at night, because at that time the price of 1 kWh of electricity will be much less.
2. Use automation, which will include heating at a certain time or only when the temperature is lowered to the set value.In this case the machine will operate only in emergency.
3. highest radiator heating is achieved by placing the boiler at the lowest point of the heating system.
4. Add a modern solution to the heating system - a warm floor, it will allow more efficient use of consumable heat throughout the room.
5. return to the use of dual-rate counters.Another version of their rational use for heating - heat accumulators buy.These containers with water can warm up the room during the day, while the liquid will heat up during the night (when the electricity will cost much less).

That's all that I wanted to tell you how to install and connect the electric heating boiler with his hands.Finally we recommend you to buy the device only on high-quality manufacturers to heating the house has served as long as possible.Among the leaders in the production of water heaters can be divided into three optimal price and quality: Protherm (proterm), Nevsky (of its connection, we have considered in the video) and Galan.
