How to connect the boiler to the mains ?

Scope

cylinder about to use an electric boiler for heating, say very rarely, but still an option there.Its use is recommended in the case if the room does not have a complicated heating system and the power unit is sufficient for normal operation (typically 1 kW can serve 10 sqm).So he warms a small house you need to install a circulation pump, or hot water will not be able to effectively spread heat sinks (not enough pressure).

draw your attention to the fact that there are devices such as the storage and flow.The first option el.boylera expends less energy for heating, but require a certain space for capacity allocation.The second option is more compact, but due to its high power consumption on the order of more electricity.

to electrical work

Requirements To readers of "Sam electrician" is not subjected to a life of danger and were able to connect the electric heater to the network without any problems, give a few simple rules that you should consider:

1. sure to turn off electricitythe main panel for assembly work.
2. Connect wires only through the terminal blocks or soldering.There are no "grandfather" twists should not be.
3. Protect the RCD and ground water heater.If the home is a two-wire network, make sure the grounding system on the site.As for the old types of apartments - Khrushchev, in which there is no ground very often, then you can get out of the situation by connecting the boiler through the RCD and the machine.It is also possible to connect to a power supply via the Emergency circuit breakers, which combines the two types of protection.In that case, if there is no "ground" in the country, difficulties should arise, becausePE-defense is not difficult to do by hand.
4. Since water will pass close to electrical appliances, take care of the quality of wiring protection from moisture.Get the outlet with a degree of protection not less than IP44, the circuit breaker and the RCD should be in a waterproof housing.
5. If the unit is connected directly to a network (not a plug), use non-combustible cable VVGng or its better execution - NYM.
6. Mounts to the wall must be reliable.Typically, the tank capacity can be up to 100 liters.The thickness of the anchor in this case must be at least 8 mm.On the wall of the boiler installation is not recommended to produce plasterboard.In this case it is better to place the water heater on the floor.

basic process

Instructions for connecting the boiler will be provided at the point when the whole heating system have been placed to the installation site.All you need is - hang the heater on the wall and connect it to the power supply.

Fixing to the wall

consider more sophisticated option when installing the storage-type water heater will be applied, asinstallation of a water heater less laborious passage (due to the lower weight and size of the product).First you need to mark the wall in accordance with the placement of fixtures.To do this, measure the distance, you need to install the mounting ears, and move it to the wall.Be sure to use the building level to the ears were placed horizontally.

Any misalignment will affect the performance of the unit, and hence its service life and efficiency.The tank must be placed perfectly straight in both the horizontal and vertical plane.After marking

take drill zasverlivaem holes in the wall and trying to drive them dowels.Then they are screwed into the anchor hooks and hang the boiler on the wall, as shown in the photo below.

not worry about the decoration of the walls.Even if we have already made repairs in the apartment, with careful installation you do not damage the surface.For detailed instructions on installing and connecting the wall type water heater, you can also see in the video example:

Wiring

When the product is securely anchored in the wall requires to bring to it the wiring.Consider two variants of the existing wiring connection of the meter.

Option 1 - Power sockets

This option is used if the capacity of the unit is less than 3.5 kW.In this case it is necessary to bring the outlet to a place to connect the boiler to the electricity network, as shown above.The minimum cable cross section should be 2.5 mm.kv.(Copper conductor).It is recommended to carry out in advance of the cable cross-section calculation, so he was able to withstand the stresses arising.

Option 2 - Power panel

If you have purchased more than 3.5 kW device, use the power from the outlet is prohibited, because it simply does not withstand such loads.In this case, you need to take to the water heater cable directly from the distribution switch board installed in the apartment or house.

should draw your attention to the fact that the connection of the boiler to a single-phase network can be carried out if its power is no more than 4 kW.If the nominal capacity of the above, make sure the network must be a three-phase (380 volt).

Once you decide the method to connect the boiler to the electricity needed to power the device and move on to the next step.

Setting protection

Since the establishment of heating system you will have to deal with powerful equipment, as well as the close proximity of the water and the current need to take care of the protection of the boiler and of itself.

The first thing to realize connection of the RCD and circuit breaker to the line, which will maintain the unit.If the power will come from the power outlet, install protective equipment is recommended at the distribution board.In that case the power will occur directly from the panel, the protection device must be near the object to be able to conveniently and safely perform maintenance.Do not forget that at the close placement of the RCD and AB should be protected from moisture devices.It is recommended to place the product in a sealed box.

The network 220 must always be connected elektroboyler through a two-pole circuit breaker.Remember the important rule - Automatic connection is established with the top run-in phase and zero.

first launch

When all the electrical work will be finished, you should move on to the start-up of equipment.The first thing you need to check all wiring and tubing and the integrity of the seal.If no abnormalities are found, you are ready to power up.To do this, first open the valve on the pipes (cold and hot circuit), then you can include a gun and RCD.We strongly recommend that you review the instructions in the video, in which the entire process is described clearly:

In conclusion

installation of electric boiler for heating is recommended for small houses and apartments.The cottages are spacious and private homes is better to carry out the connection of the electric boiler, asit is more powerful and is able to more efficiently heat the room.If you are still configured to use this type of water heater, be sure to add in the circulation pump, the hot water under pressure into the cooler, thereby effectively warmed up the room.
