Frequently asked questions

Monthly consumption of the boiler depends on a large number of factors (the location of the building or apartment, size of the building, the interior design temperature, the thermal insulation of the building, the heat transfer through thermal bridge, the ventilation losses, heat losses through carpentry, the surface of the transparent elements and their orientation to certain sides of the world, solar gain, etc.), these factors determine the energy performance of building or apartment (for this reason the energy performance is predominantly different for each object or apartment).

In order to determine the energy performance of the building, it is necessary to analyze all the above mentioned factors, done by the heating designer / engineer in energetics, that is, in order to know in detail the energy performance of your facility, it is necessary to hire a heating design company.

On the home page there is a pdf file describing the estimated consumption of our electric boiler, if you know the energy class of your facility.

The power of the boiler is also determined by the energy performance of the building or apartment. The "Products" page shows an estimate of the extent to which the maximum surface of the building can be heated by the appropriate boilers; this information should be taken with reservation, since the optimum operating conditions of the boiler are considered. This information is usually provided by the heating installers based on their experience, after looking at your facility or apartment.

The fuses can be ejected for several reasons, and the main ones are:

  • Automatic fuses are consumable and after several ejections, they must be replaced with new ones.
  • Poor quality of automatic fuses.
  • Weakened bimetals are ejected at a lower amperage than declared.
  • Incorrectly adjusted electrolyte in the system.
  • Inadequate washing of the central heating system, so it still contains impurities.
  • The system contains tap water, not distilled (when the system is washed out by the contractor, insert the distilled water into the system, and then add the bicarbonate to the boiler according to the technical instructions to achieve sufficient heating power).
  • Distilled water must be in the system, not rainwater, ordinary water, well water, deionized or demineralized water, as well as other types of water or antifreeze.
  • In case of excessive power (too much sodium bicarbonate in the system), all distilled water from the system must be drained, then the system should be washed with tap water, which is replaced with distilled water afterwards. Further, it is necessary to adhere to the technical instructions for installation (adding sodium bicarbonate, if necessary). Sodium bicarbon boosts the power of the boiler. Please note that the boiler does not have a heater in it, but it is an electrolyte itself, that is, water in a system with a certain percentage of sodium bicarbonate, according to the instructions. When adjusting the electrolyte, be sure to monitor the operation of the ammeter and the operating parameters specified in the technical instructions.

This type of ionizing boilers work in the base (pH 8 ÷ 10) and not in the acidic environment and requires exclusively distilled water in the system. Note that poor quality distilled water is sold to a large extent, so it is necessary for the producers to have a guarantee sheet that it is truly distilled water. In the central heating system, you can check if it is really distilled water by turning boiler on when the system is filled with distilled water, if ammeter shows none or very low amperage (0.5 ÷ 1A) then distilled water is valid and can be used. By adding sodium bicarbonate (according to the technical instructions), you generate an electrolyte and, thus, increase the amperage of the boiler.

Generally, distilled water should be contained in all heating systems, but it is mandatory for this system. If you insert tap water of a non-guaranteed chemical composition into the system, this can lead to reduced electrical conductivity of the electrodes (amperage drop). If electrodes get dirty, the boiler should be cleaned of dirt (electrodes and pipes). All metal parts that transfer electricity need to be cleaned, and then return the boiler back to the heating system, completely clean. If the pipes and electrodes are damaged due to impurities or stones of larger volume, so that their degradation has occurred, it is necessary to replace them with new ones (contact us).

Due to the operation of the boiler in the acid environment (in the event that the heating installer inadequately washed and cleaned the heating system with certain chemicals, which he determined on the spot depending on the installation material), oxidation of electrodes, corrosion or even the formation of sludge may occur on the boiler itself or the installation. This can be noticed by the fact that the amperage (power) of the boiler will drop and the boiler will not reach the required temperature. Note that the company "Ekoterm 2001" is not responsible for systems that are not adequately prepared before their use. Only the proper interpretation and installation of the heating installer can provide safe, permanent operation of the boiler and save up to 45% compared to standard electric boilers.

Setting the boiler temperature is done with room and operating thermostats. These are standard thermostats that measure the temperature - room temperature and the operating temperature of the liquid in the central heating system. The operation of the boiler depends to a large extent on the operation of the thermostat. Low quality thermostats can lead to increased power consumption, as they supply the boiler with delayed information. The best are digital thermostats with high accuracy:

  • Room with hysteresis of 1 ⁰C ± 0.1 ÷ 0.2 ⁰C;
  • Operating with the hysteresis 2 ÷ 4 ⁰C ± 0.5 ⁰C;
  • We offer checked and high precision thermostats.

Setting the temperature of the boiler is of great importance for the boiler's electricity consumption and it is very important to handle them properly.

The heat exchanger should be used where it is required to heat the sanitary water, if there are very dirty central heating systems and where the boiler electrodes are intensively collecting impurities, or in systems where the secondary system requires antifreeze or other fluid (cottages and houses that are occasionally heated and need to be protected from low temperatures).

Electronics is necessary. Devices such as contact switches, ammeters and fuses are necessary. All of these components are packed and can be ordered from our company under the name "Electro-cabinets" or "Cabinets with automatic control".
