You can have a warm and cozy home and contribute to environmental preservation at the same time by using electricity for heating.

Calculation of power

To guarantee that the source of thermal energy can support the entire load on heating and DOS, it will first be necessary to compute the power.

Using the enlarged indicator or, for a more precise calculation, the calculation of heat loss through the house’s window openings and external wall structures, you can determine the electric boiler’s heating power for heating on your own. In the first scenario, 1 kW per 10 m2 is the ratio used for calculation.

That is, a 5 kW boiler will be needed for a 50 m2 home, and a 10 kW boiler for a 100 m2 home.

To account for load loading, an additional thirty percent are added. To ensure more precise computations, it is imperative to ascertain the lowest temperature in a frigid five-day period for a specific residential area, as provided by SNiP, and account for heat loss via the exterior walls of the building.

For a house 50 square meters

Estimate the amount of heat loss that will offset the electric boiler for a small, one-story summer cottage with the following specifications: two chambers, double-glazed windows measuring 1 by 1.2 meters each, and a ceiling height of 2.4 meters.

Calculate the electric boiler’s power for a 50 m³ house using your own hands:

• The required internal air temperature in the room, 18 s.
• The average temperature of the cold five days per year, -15 from.
• The need for DHW, 4 people.
• The area of the brick wall in 2 bricks (51 cm), 67.2 m2.
• Square of windows, 4.8 m2.
• Square of walls without windows, 62.4 m2.
• Ceiling and floor area 49 m2.
• Window heat loss, 0.476 kW.
• Walls of the walls, 5.15 kW.
• Ceiling heat loss, 0.43 kW.
• Heat loss of the floor, 0.43 kW.

Therefore, the 50 m2 house’s overall heat loss is 6.486 kW. Since the electric boiler should have a minimum power of 7 kW, this should be sufficient to heat the rooms.

For 100 square meters

The power of an electric boiler unit for a 100 m2 country household is calculated as follows:

• Internal air temperature, 18 s.
• The average negative temperature is -15 from.
• The need for DHW, 4 people.
• The area of the outer wall in 2 bricks (51 cm), 100 m2.
• Square of window openings, 6 m2.
• The area of wall structures without windows, 94 m2.
• Ceiling and floor area 100 m2.
• Heat loss of window structures, 0.714 kW.
• Walls of the walls, 7.33 kW.
• Ceiling heat loss, 0.875 kW.
• Heat loss of the floor, kW: 0.875 kW.

Given that the 100 m2 house loses 9.794 kW of heat overall, a 10 kW boiler is selected for electric heating.

Drawing

Correct execution of the boiler’s heat engineering component is crucial, but it’s also crucial in this design. Therefore, the contractor will require the unit’s assembly drawing and the connection diagram for its electric part in order to perform assembly work.

The boiler’s connection diagram

These nodes should make up the basic boiler design for heating plants:

1. The pipe case will become more reliable if it is made of a steel pipe F219x3 mm and a length of 65 cm.
2. From 3 pipes: input, output and drainage, 2 by 30 mm and 13 mm will be enough.
3. Electrodes are purchased ready -made, by the power of the boiler.
4. In the case, the holes are performed to supply to the expansion tank and inserts of primary sensors.
5. Inside the case arrange a platform for fixing the hets.
6. The prepared pipes according to the drawings are welded to the made holes using an inverter -type welding machine.

Additionally, a plan needs to be equipped with an expansion tank, a thermostat, and an electric boiler system. After that, you will need to put together a polypropylene pipe diagram by hand.

Tools

You will need pliers, an inverter welding machine, a grinder, a set of locksmith tools, and a measuring tool to complete the boiler’s heat engineering portion. You will need an electrician, a tester, and a soldering set for the electrical portion.

Necessary materials

The number of heating elements, the principle of operation, and the design chosen will all influence the list of materials. A minimum of 3 mm thick metal sheet is needed if the case is made of sheet; otherwise, F219x3 pipe will be needed.

About 10 cm of diameter is required for one heating; thus, for the pipe f 219, only two heating plants are feasible. The case should be 500 mm longer than the electrodes in length.

Auxiliary materials: thermometer, pressure gauge, sealing material, welding electrodes, thermocharge, valves, and safety valves are needed.

Electrical equipment is determined solely by boiler power; if the boiler has a capacity greater than 5 kW, special energy supervision measures and the maintenance of independent power for electric boots via separate protection systems will be necessary. Additionally, each heater needs to have an automatic heater.

Every heating element in a home with a three-phase diet is installed on a different phase. Equipment needed to connect the boiler as a whole: contact pads, starter, machine guns, and cable.

How to make an electric boiler for heating a house with your own hands

You can begin assembling an electric boiler for residential heating once the power has been chosen, the housing drawings, power supply, and protection circuit have been located or constructed, and all necessary parts, tools, and blanks have been assembled. Detailed instructions for manufacturing an electric boiler on your own:

4. Carefully process the edges of the holes with a grinder and weld the drainage pipes with the drives, the input/output of the coolant.
5. Further to the hole you need to weld the stacks.
6. They perform the lid of the case with removable so that it is possible to change the heater during operation.
7. At the bottom of the case, a plate of 5 mm is installed with the function of flanges for the heating elements.
8. A grounded hairpin and wall or floor attachment system are welded to the body.
9. After welding the structure, check its tightness, having previously closed the pipes with the valves.
10. Install the thermostat.

Installation and connection

Following the assembly of the heating circuit, hydraulic heading, temperature sensor, locking reinforcement, check valve, safety valve, expansion tank, and heating devices, a hydraulic test of the entire system is carried out using the density of the assembled circuit and the pump’s working pressure.

Water is poured into the network, the circulation pump generates pressure, and every joint is carefully inspected for leaks or swimming. After removing every issue, the collected power supply scheme is tested.

An experienced electrician should put together the electric circuit, ensure that it is grounded, check that the heating elements are operating, and safeguard the boiler from overload. In order to prevent this, install a protective shutdown mechanism.
