Instructions for installation, strapping and connecting to the network of the electric boiler

Having an effective heating system is essential for keeping your house warm and comfortable, especially in the winter. A lot of homeowners are choosing electric boilers because of how simple they are to install and how little maintenance they need. Whether you’re installing a new heating system or looking to upgrade your current one, it’s important to know how to strap, install, and connect an electric boiler to the home network correctly.

Careful planning and consideration of several factors are necessary when installing an electric boiler. You must, first and foremost, decide where your boiler should be placed. This location should allow for adequate ventilation and easy access for repairs and maintenance. You should also make sure that the area is clear of any obstacles and has enough room for the boiler and any pipes that will be required.

Ensure that you have all the required tools and materials before starting the installation process. Pipe wrenches, pipe fittings, electrical wiring, and any other parts that the manufacturer specifies may be included in this. Having everything ready in advance will make installation go more smoothly and without hiccups.

The next step is to get the area ready for installation after you’ve selected a good spot and gathered your supplies. This could entail removing any existing heating apparatus or adjusting the electrical system in your house to make room for the new boiler. Ensuring the safety and legality of your installation requires strict adherence to all local building codes and regulations.

Now that everything is ready, you can start the installation procedure. This usually entails wiring the boiler to your home’s electrical system, mounting the boiler to the wall or floor, and connecting the piping for the water supply and return. This step requires strict adherence to the manufacturer’s instructions in order to guarantee correct installation and prevent any future problems.

Rules and requirements for installation

PUE (7th edition) contains a description of all general requirements. Energy supervision services do not need to be consulted in the case of electric boilers under 10 kW. It is still necessary to arrange for installation if you wish to install a meter that tracks your electricity consumption throughout the day, as we advise you to do in order to save money. Boilers with a capacity greater than 6 kW can operate on a single-phase (220 V) network, but not at maximum power. 8–12 kW models require a three-phase power supply (380 V).

Compared to gas or solid fuel boilers, there are more options when it comes to the installation location of electric boilers. Elektracots can be placed in residential areas, such as the kitchen, hallway, or corridor, but keep in mind that in every situation, pipelines, wiring, grounding, and other communications must be connected to it. It is not permitted to install an electric boiler in the bathroom or restroom.

Minimal requirements also apply to the installation surface; a wooden wall is acceptable in this scenario, but the installation site must be isolated with a layer of non-combustible material (xylolite leaf, basalt cardboard).

Additionally, in order to facilitate maintenance and repairs, the manufacturers specify the amount of space that must surround the electric boiler. The values vary based on the model, so you must identify them in the operating instructions before arranging the installation and strapping location. Typically, this

• from 0.7 m on top of the boiler;
• from 0.5 m on the sides (including to the pipeline) and below;
• from 0.7 m in front of the boiler unit;
• at least 3 cm between the wall and the boiler.

For example, only 0.6 m from the bottom and 0.2 m from the other sides are required for the well-known Bosch Tronic Heat 3500 model. The operating instructions, which are nearly always available in electronic form, always include information on any extra installation requirements.

We’ll walk you through the installation, wiring, and connection of an electric boiler to the electrical network in your house in this article. We’ll go over everything you need to know, including how to ensure adequate insulation and safety precautions as well as the initial setup. This comprehensive guide will make the process of installing a new boiler or replacing an old one easy to follow. You can effectively and safely incorporate an electric boiler into your home’s heating system by following these instructions, guaranteeing warmth and comfort for many years to come.

Detailed step -by -step instructions for installing and connecting

Installation of an electric boiler on the wall

1. Clean the wall of dust and dirt.
2. Installation set: hinged mounting plate, dowels and screws, as a rule, come with the boiler.
3. Make markings on the wall in accordance with the fasteners and drill the holes of the diameter corresponding to dowels (usually Ø 10 mm), insert the dowels into the holes.
4. Piece the boiler into threaded hooks, and then tighten the screws.

Fasteners may vary slightly depending on the model. The Protherm models require you to first adjust the mounting bar before hanging the boiler on it. The instructions always include a detailed algorithm.

Organization of strapping

All that is required to heat electric boilers in monoblock cases, which come with all the components already assembled, is to connect the appropriate pipe and reverse lines. Water must be added to the system in order for it to return through the fuel tap.

All components of basic heating boilers without an expansion tank or circulation pump are connected in line with one of the above schemes.

1. First, the hydropolitan and expansion tank is mounted on special mounts.
2. Further, in accordance with the scheme, pipes are laid with a circulation pump, filter, and a security group installed on them .

Some cut-off shut-off cranes, which should be installed before and after each binding element so that, in the event of a malfunction, it can be replaced without lowering water from the entire heating system, are not shown on the diagrams of the electric boiler’s strapping. Use tans to secure the swinging sections to the wall for structural integrity. For every threaded joint, sealing tape is advised.

Electric wiring and connecting an electric boiler to it

Electric boilers are very powerful, but only low-power models—typically found in apartments—up to 3.5 kW are permitted to be connected to a socket. In other situations, there is only direct communication.

A combination of RCD + circuit breakers (one switch for each phase) or a diphthenial protection machine connects the boiler unit to the electrical grid. A sufficient section of the power cable is required; this can be determined, for instance, by using the electric boiler’s power.

Accordingly, the cross section of an electric boiler with a three-phase network and a capacity of 18 kW should be 10 mm 2 when using a cable with copper cores (the maximum load that can be used, per PUE, is 19 kW). Usually, the electric boiler’s passport contains information on the precise cable cross section and nominal values.

The number of phases is the only variation in the electrical connection diagram shared by all electric ships.

Connecting the phase to any of the contacts (U, V, or W) is sufficient when connecting to a single-phase power supply. An electric boiler must have a jumper (see scheme) removed and the phase connected to each of the three contacts when connected to a three-phase (380 c) power grid. In every scenario, zero and grounding (n and PE, respectively) are connected in the same way.

We also advise connecting an electric boiler via a voltage stabilizer, as automation failure brought on by voltage spikes is a frequent issue in our environment.

Grounding

High-power electrical installations, such as residential electric boilers, need to be properly grounded in accordance with all regulations. If the country house has no grounding, the required cross section wire for the internal distribution shield of grounding should go straight to the electrodes buried in the ground or, if it is already organized, from the boiler housing.

The outer portion of the protection should ideally be no more than one meter from the house’s foundation, but it should be placed somewhere where no one is guaranteed to be at the time of the power grid breakdown.

Order of work:

1. Dig a triangle with a shovel and a supply to it with a depth of 0.5-0.7 m, the length of the sides of the triangle-1.2 m.
2. Puttop with a grinder and beat in the ground along the tops of the triangle vertical grounding electrics-metal corners 50*50 long 2.1-2.2 meters. They should only stick out of the ground a little so that in the future it could be welded to horizontal grounding plates.
3. By forming the sides of the triangle, weld to vertical electrodes 3 strips of metal 1.2 m long, 4 cm wide and at least 4 cm thick.
4. Weld to the nearest top of the triangle and draw a trench to the foundation of the house of the stainless steel strip 4)*4 mm.
5. Connect the grounding wire coming from the distribution shield or electric boiler housing with a bolt connection.
6. Pour the structure of the earth.

The trial launch of the boiler

1. Check the insulation of all wires, reliability of connecting couplings, cranes and joints.
2. Run the water into the heating system through the recharge crane, opening the valve is not completely so that the water is gained under lower pressure.
3. Lower the air through the air vent, in some models there is an automatic air vent.
4. Construct the pressure in the system using a pressure gauge, the exact nominal values are indicated in the electric boiler passport, usually 1.3-2.0 bar in working mode and 1.0-1.3 bar with the boiler is disconnected.

Remember that in order for the warranty to be fully fulfilled, the connection and commissioning must only be done by qualified professionals, per the guidelines provided by the majority of manufacturers.

Installing an electric boiler is a wise decision if you want to heat your house effectively. You can successfully finish the installation process if you have the correct instructions. Never forget that safety comes first. Before starting any work, always turn off the power. If in doubt, seek professional advice.

Choose a good location for your boiler first. It ought to be close to a power source and conveniently accessible for maintenance. Make sure there is adequate room for any required piping and ventilation. Adequate insulation surrounding the boiler can enhance its performance and minimize heat dissipation.

Next, get the installation site ready. This entails building a stable foundation or platform for the boiler. Assemble the boiler and its parts carefully, adhering to the manufacturer’s instructions. Keep a close eye on the wiring and make sure that every connection is safe and insulated.

It’s time to link the boiler to the electrical network after everything is set up. To prevent any safety hazards, precision is required in this step. Verify that your boiler’s voltage and amperage requirements are compatible with your electrical system by checking them twice.

Check the boiler to make sure everything is working properly after connecting it to the network. Make any necessary adjustments and look for any leaks or strange noises. In order to ensure warranty coverage and comply with regulations, don’t forget to register your boiler with the relevant authorities.

In conclusion, installing an electric boiler can minimize your home’s environmental impact while ensuring dependable heating. You can benefit from economical and cozy heating for many years to come if you adhere to these guidelines and put safety first.
