Electrode boilers for heating a private house of direct

Heating

If you have not yet decided which boiler you need to heat a summer house or a small country house, you need to be guided by a simple condition - the availability of fuel. In most cases, it is traditional electricity, which is almost always supplied to the site. Therefore, we suggest today to consider as the main source of heat - the electrode boiler, which will save up to 40% of the cost of electricity.

Special features

Although electrode boilers work on electricity, their principle of operation is somewhat different from conventional electric boilers. They are referred to as direct heating heating devices, when heat is immediately transferred to the energy carrier, therefore their price is lower than conventional conventional devices.

So it is possible to increase the capacity of the unit, because there is no barrier in the process of its transfer.

  1. Heating occurs due to electrodes immersed in a tank with coolant.
  2. Electric current is conducted through it with a frequency of 50 Hertz, therefore, the phenomenon of electrolysis is eliminated, and scale will not form on the inner surface of the boiler.
Work cost-effective electrode boiler
  1. The heating of the coolant occurs due to the resulting resistance, and almost instantly.
  2. Therefore, the capacity may be small, as there is no need to wait for the element to heat the water.
  3. This feature of the design of the electrode boiler significantly reduces the energy required for the operation of the heating system.

Tip: proper use of equipment makes it possible to save up to 40% of electricity without loss of power and heating temperature.

  1. The unit is quite sensitive to the composition of the water. In this case, ordinary plumbing can not be used directly, but must first undergo special training.

Tip: It is considered ideal to use antifreeze, which manufacturers recommend.

You should also be prepared for the electrodes to dissolve over time. This process is natural, and its speed or slowdown depends only on the intensity of the heating system.

Benefits

Before you talk about the benefits of the equipment, you must be warned that it needs reliable electrical wiring and stable voltage. We do not recommend purchasing equipment for summer houses, where the last drops often occur or there are altogether power outages. The device will not be able to function normally.

Tip: You can use an uninterruptible power supply or diesel generator.

We also recommend that you ask the administration about quotas for electricity, if any.

How electrode household boilers are installed in the heating system

If the problems described above do not concern you, below we suggest to get acquainted with the advantages of the electrode boiler:

Security
  1. The device is designed so that any possibility of leakage of electricity is excluded. Therefore, there are no sparks and other similar phenomena.
  2. During operation, it is impossible to create a dangerous fire situation, so you can leave the device unattended to maintain the minimum temperature.
The size The device has compact dimensions, so it can be embedded in a gas-fired heating system. When the electrode boiler is turned on, the gas supply stops.
Heat
  1. The heating system heats up in a very short time.
  2. The unit runs silently.
  3. It is possible to replace heating elements without dismantling the entire device.
Installation The instruction allows to install the unit in a residential area without installing a chimney and boiler room. Installation is not difficult, so it can be done independently.
Performance
  1. Device efficiency up to 96%.
  2. Energy savings when heated to 40%.
  3. During operation there is no pollution - soot, burning, ash or smoke.

Minuses

  1. The high cost of electricity. Although if you use the boiler from time to time, arriving at the cottage or in the house on the weekends, the device will be a good solution for creating a heating system.
  1. Electrode-type devices do not fit well with cast-iron radiators and metal-plastic pipes. It is better to use aluminum or bimetal batteries, and polypropylene pipes.
  1. It is necessary to maintain the specified parameter of coolant resistance. To do this, use special additives, precluding the formation of scale. We do not recommend using soda, as this will only make things worse.

Installation and use

  1. A prerequisite for the installation of the electrode boiler - automatic air vent, safety valve and pressure gauge.
  2. Valves should be placed near the expansion tank.
  3. The boiler must be installed strictly vertically, for this purpose special fastenings to the surface are provided.
  4. The first 1200 mm pipes of the heating system must be metal, the rest of the pipes of other materials.

Tip: Install the climate sensor sensor as well as the system of temperature controllers to the masters from the service center.

  1. The system must be pre-rinsed with water to which the special equipment required by the manufacturer has been added. Otherwise, the efficiency of the boiler will decrease significantly.

Tip: the best coolant, according to many manufacturers, is distilled water.

  1. When choosing radiators, it is necessary to consider the total displacement, which must correspond to - 8 l / 1 kW.

Conclusion

Electrode heating equipment - reliable and energy-saving, allows you to create comfort in the house and has a number of advantages. It is only necessary to adhere to the rules of installation and operation of equipment.
