Electrode boilers – energy-saving heating boilers

If we compare various engineering systems of buildings and structures, heating is technically one of the most complex, and operationally one of the most important elements of support.

What criteria are decisive when choosing a heating system?

This:

• engineering and construction solutions related to the building design;
• volume of space for heating;
• price and availability of fuel or electricity;
• budget.

General view of the connected EOU to the heating system

Currently, there is a clear trend towards replacing central heating with autonomous units that run on the following types of fuel:

• diesel;
• fuel oil;
• pellets or firewood;
• coal;
• gas.

The high cost of traditional heating plus the poor performance of heating plants are the main reasons why stand-alone installations are becoming increasingly popular.

If we take into account the trend of rising prices for all types of fuel, it becomes clear why energy-saving electric heating boilers are becoming increasingly popular heating equipment (see photo below).

Electrode boilers for heating a private home are used for installation in closed-type heating systems in which a coolant (usually water) circulates. In such networks, the presence of a pump is not necessary.

An energy-saving heating system can be an element of various types of heating systems, and also serve as both a main and auxiliary heating solution.

When using several electrode boilers, they can serve as an autonomous boiler room even for heating fairly large rooms.

Advantages of EOU

The energy-saving heating installation EOU has the following advantages:

• efficiency;
• compactness;
• autonomy;
• reliability;
• durability;
• no hazardous waste;
• fire safety.

Arguments in favor of EOU boilers (compared to gas installations)

1. The growth rate of the price of natural gas is higher than the growth rate of the cost of electricity;
2. At peak loads, the pressure in gas networks does not allow high-quality heating of the premises;
3. Lack of permitting procedures for equipment installation.

EOU design and heating element power calculation

To heat the coolant in the EOU, an element made of a special alloy is used, which has a heat transfer coefficient of 96-98%. If we take into account standard heat losses (within the standards), then the average power of an EOU for heating a room with a volume of 70 m3 is 1 kW.

Important! To increase the electrical conductivity of water, you can add baking soda (sodium bicarbonate) to it at the rate of 30 g per 100 liters of water.

When the EOU is included in the water heating system, its active operation time ranges from 2 to 9 hours a day. The operating mode is automatic and is regulated by a special temperature sensor, which is connected to a relay.

The operation of an EOU in a closed heating system improves the circulation of the coolant due to its heating. Thus, the use of the installation allows you to raise heated water to a height of up to 25 m (depending on the useful power of the installation)

We offer an electric boiler with unique properties that are superior in energy savings to any heating element and induction boilers by at least 30-40% and are close in their economic and operational indicators to the use of gas equipment. 2. An ideal solution for those who do not have gas supply - at the moment the most relatively inexpensive way to heat houses is to use gas. However, if you look at it, this method also has its disadvantages:

– high cost of gas equipment;

– high cost of connecting to the gas main;

– mandatory approval of installation and connection is required;

– fire hazard;

In addition, gas is becoming more expensive every year and, according to some experts, prices for gas and electricity may become equal as early as 2020. These factors make the installation of gas equipment unprofitable.

3. Electrode technology allows you to set the power consumption depending on the set temperature - The boiler reaches its maximum power consumption power only when the highest recommended temperature is set at 55 degrees Celsius on the thermostat. Up to this value, the boiler will consume significantly less electricity - in proportion to the set temperature.

4. Compact and easy to use and install - due to its small size, there is no need for a separate technical room. For example: can be installed under a sink or stairs. Installing the boiler requires minimal labor (See installation instructions).

5. Inexpensive – due to its unique structure and the use of polymer materials, the boiler has a relatively low cost in comparison with similar boilers on the market.

6. Durability of the boiler operation and minimum maintenance – Preventive maintenance of the boiler operation and replacement of the coolant in the heating system must be carried out no more than every 3 years of operation. Before the start of the season, if necessary (in case of leaks), it is necessary to fill the system with coolant.

7. Coolant (Antifreeze) KOTERM ECO prevents defrosting of the heating system

– all seasonal, environmentally friendly coolant KOTERM ECO containing special components that protect your heating system from corrosion and freezing in winter, and will also ensure long and stable operation of the electric boiler.

8.

Installation and installation of EOU

For installation of equipment, standard pipeline and plumbing elements are used: couplings, adapters, hoses. The input is connected to the return line, the output to the direct line of the heating system.

General connection diagram

If the EOU is used as backup or auxiliary heating equipment, this means that the system already has a heating boiler. In this case, the EOU is connected in parallel to the heating boiler (or boilers, if there are several of them).

If there is a circulation pump in the system, the EOU is connected to the return line of the heating system. The electrical installation is installed after it.

The principle of installation work associated with installing an EOU in a heating system is the same as when working with heating boilers (gas or electric), various convector stoves, AGV, etc.

Heating with the installation of an electrode boiler can be done with your own hands (see video).

Installation of electric boiler EOU in the heating system

Guide for informational purposes

Before connecting an electric boiler to your home heating system, you must carefully read the instructions!

Before installing an electric boiler, it is necessary to flush the heating system with clean tap water to remove possible installation debris.

Installation

The boiler must be installed vertically, out of the reach of children. There should be free space above the boiler for maintenance work.

Connection diagram of an electric boiler "EOU" to a radiator heating system at home

We recommend this scheme as the most efficient and energy-saving.

1. Boiler.
2. Control panel + thermostat.
3. Circulation pump.
4. Expansion tank + safety group.
5. Shut-off valves.
6. Radiator.
7. Drain tap.
8. Pipe 20 mm (outer diameter).
9. Pipe 25 mm (outer diameter).

Thermostat

To control the heating temperature of the boiler (up to 60 degrees Celsius with the ability to program the boiler for every day, sold separately.

Important

To control the boiler, it is necessary to set the Thermoregulator settings to work only with the coolant temperature sensor. Turn off the air sensor!

Prohibited

Install taps, shut-off or control valves in the area from the boiler outlet to the expansion tank (without an additionally installed pressure relief valve or safety group). There is no need to install a coarse filter on the system, because if it becomes dirty, the circulation of the coolant is reduced, which will lead to overheating of the coolant.

Not recommended

Installation of the boiler in a system with large-volume radiator batteries (such as Soviet cast iron) with a total system capacity of more than 70 liters and aluminum radiators (over time they release aluminum oxide, which negatively affects the stable operation of the boiler).

We recommend

Use ordinary bimetallic radiators, plastic pipes reinforced with fiberglass, with a diameter corresponding to the connection diagram, fill the system only with standard Coterm Eco antifreeze.

Power connection

To connect the boiler from the power supply input, a cable with a cross-section of at least 4 mm2 is required, connected through a separate input circuit breaker with a nominal value of 30A (the use of an RCD is not permitted). Check that the supply cables are correctly marked and follow them when connecting the boiler. Protective grounding with a resistance of no more than 4 Ohms from a copper wire with a cross-section of 4-6 mm2 must be performed. The boiler must be connected in compliance with all PUE and fire safety rules.

Turning on the boiler and selecting the operating mode

1. Turn on the automatic switch on the boiler control panel.
2. Set the required temperature on the thermostat. After reaching the set temperature, the boiler will turn off automatically and turn on when the temperature in the system drops 4 degrees below the value set on the thermostat.
3. Electricity consumption directly depends on the set temperature value; the higher the set temperature, the greater the consumption. The boiler will reach its declared power rating when the coolant temperature reaches 50 degrees Celsius.

For example, a 6 kW boiler will reach a consumption power of 6 kW when the coolant temperature in the system reaches 50-55 degrees Celsius. Electricity consumption at a given 30 degrees of heating on the thermostat will be approximately 3 kW.
