Energy saving electric boilers for home

Climatic offers a wide range of electric boilers of various capacities. Read the information or call our consultants to select the required boiler model.

An electric heating boiler consists of a heat exchanger, a block of heating elements, a control unit and control and safety devices. Some electric boilers are equipped with a circulation pump, expansion tank, safety valve and filter. The electrically heated coolant circulates through the system of pipes and radiators, providing heating of the premises, as well as heating the water in the boiler. An electric double-circuit boiler is used for heating and hot water supply, a single-circuit one is used only for heating the house, as well as for underfloor heating.

Compared to boilers using other types of fuel, electric boilers are cheaper, more compact, safe and quiet. Connecting electric boilers is much simpler and more inexpensive than other types of boilers. Due to their compact size and low weight, electric boilers are wall-mounted, do not require a separate boiler room and installation is allowed in utility or utility rooms, storerooms, in the kitchen, in the basement, and even in living rooms.

Electric boilers are easy to operate and do not create harmful emissions and odors, do not require constant maintenance, expensive cleaning and regular purchases of fuel.

Dependence on the stable availability of electricity and high requirements for the quality and reliability of electrical wiring. You should also take into account the rather high cost of electricity. For an informed decision on the purchase of an electric boiler, it is recommended to make a preliminary calculation of the cost of electricity.

240 days X 8 hours a day X boiler power X cost of 1 kW of electricity

Electric boilers with power up to 12 kW are available in single-phase (220 V power supply) and three-phase (380 V power supply), and boilers with a power of more than 12 kW are only three-phase. Most electric boilers with a capacity of more than 6 kW allow multi-stage power regulation.

To select a specific model of an electric boiler, you can contact the consultants of the Thermomir company. Remember that in addition to the boiler itself, it is necessary to purchase other elements of a full-fledged heating and water supply system (radiators, pipes, pumps, thermostats, a boiler and much more), therefore, it is better to entrust the selection of equipment and its complete set to professionals.

Comparison of EOC and gas boilers

For many years, natural gas has been the number one energy source.It was used both for domestic purposes and on an industrial scale. The disadvantages of gas boilers became apparent after the appearance of electric EOS designed for autonomous operation. Gas equipment is inferior to several positions at once:

• lower efficiency value;
• boiler operation is accompanied by emissions of harmful substances;
• high fire hazard;
• dependence on the gas main.

Design features

The role of heating elements is played by two electrodes made of a special heat-resistant alloy. The function of the coolant, most often, is carried out by water. Taking into account the permissible standard heat losses, in order to create a comfortable temperature in a room with a volume of 65 m3, 1 kW of electricity is enough.

The main units of the installation:

• boiler equipped with automation;
• pump for circulation of the coolant (depending on the modification);
• expansion tank to collect excess liquid;
• pressure gauge, outlet valve;
• mud filter;
• automatic machine for current from 1A and an electromagnetic starter.

Power

The main indicator of electric boilers for hot water heating is power. In this dependence, the connection can be carried out both to a 220V source (single-phase circuit), and to a higher 380V (three-phase circuit).

Main technical parameters of energy saving electric boilers

There are several criteria to consider, you do not know which is the most economical electric boiler to choose for your home. Here they are:

• unit dimensions and installation area;
• the boiler must be equipped with an automatic system that saves energy. In this case, as much heat will be produced as required for a particular room;
• the functionality of the device is the rapid heating of the liquid that passes into the chamber. This parameter determines the efficiency of the unit;
• the manufacturer's guarantee is the efficiency and reliability of the equipment. Depending on the manufacturer, this period can last up to 30 years;
• manufacturers can be not only foreign, but also domestic.

Power is an important indicator. Depending on it, the connection can be carried out both to a 220 V source and to 380.

Principle of operation

The EOU is a direct-acting device, that is, there are no intermediate components in it. The operation of a water heating boiler is based on the movement of ions between a pair of electrodes with a frequency of 50 oscillations per second. And since any chaotic movement of electrically charged particles produces thermal energy, the liquid is heated.

A large temperature difference is created at the inlet and outlet of the electrode boiler, which forces the heated liquid to rush up the direct supply pipeline to a height of 25-30 meters (depending on the boiler model).

The units operate in automatic mode, temperature control is carried out by a special sensor connected to the relay. The continuous operating time of the equipment is 2 to 9 hours. The heating chamber of the installation has a small capacity, which contributes to the instant heating of the heat carrier up to 95 ° C.

EOU are designed for closed water heating systems of all types and can serve as both the main and auxiliary heat source.

It is allowed to use rainwater, melt water and frost-resistant liquids as a heat carrier.

The boiler can be operated with or without a water circulation pump. In the first case, electricity consumption will be reduced. The control over the operation of the ECU is carried out by a thermostat, which, as the air temperature changes, disconnects or reconnects the installation. Thus, the room temperature is maintained at the set level.

Energy-saving heating electrical installation EOU

If you don’t have gas or don’t want to spend tens of thousands to supply it just to heat the building, which one should you prefer? An expensive system with a gas boiler or an EOU for several thousand rubles, which can be launched the very next day after the purchase, while gas is unlikely to be carried out in a week?

Summer warmth all year round

Electric hot water heating installation of flow type EOU is designed for heating the coolant in closed water heating systems (autonomous heating) of houses, cottages, apartments, summer cottages, garages, industrial, warehouse and other facilities both without a circulation pump and using forced circulation.

The electrical installation has no analogues. This is an environmentally friendly, modern, autonomous, highly economical, reliable and small-sized heating equipment. EOU makes it possible to heat any room without special costs. The unit crashes into the heating system, connects to the network and, after switching on, works in essence as an instantaneous water heater.

Installations are of two types - single-phase and three-phase. When two or more units of the same power are included in the system, the heated area increases two or more times (two 3/36 modules heat an area of ​​1500 m2, three 3/36 modules, respectively, 2250 m2, etc.), which allows you to heat any room. Moreover, the EOU will fit any heating system with any pipes, radiators or registers. Naturally, the system itself must be installed in compliance with all rules and regulations.

The unit can operate with or without forced circulation. The rise of water in the system without a pump is from 3 to 24 meters (depending on the modification), due to the large temperature difference at the inlet and outlet of the electrical installation, which allows heating one-story and low-rise premises. When using a pump, energy consumption is reduced. And in order to control the operation of the installation, a thermostat is included in the kit, which measures the air temperature in the room and turns on / off the EOU, maintaining the set temperature. The heating element does not fail even if power is supplied to the EOU and there is no coolant in the water heating system.

Special skills are not required to connect the EOC. It will not be difficult for a plumber or an electrician to mount it. In the technical passport, all the processes for the installation and operation of the installation are available and described in detail.

What is important, the ECU can be installed even in every room, as long as it is economically justified. For example, if the optimal temperature in the warehouse is plus 16, then in the office space - plus 21. It makes no sense to heat the warehouse using a single heating system. And already in a season, the second EOO will pay for itself due to the saved energy. At night, you can set a minimum temperature setting, which will affect the payment of energy bills.

The water heating system, mounted on the basis of the EOU, is economical, therefore, heating the premises will cost you two to three times less than when using boilers for liquid and solid fuels (coal, fuel oil, wood), electric boilers and electrical systems for heating the air.

EOC TECHNICAL CHARACTERISTICS

1. The EOC uses a special alloy heating element, which is developed on the basis of the latest technologies, thanks to this, the EOC has a high efficiency - 98%.
2. Working voltage: 220/380 V ± 25%. One kW of power of the EOU heats 20 m2 of area (60 m3 of volume) of a room with a ceiling height of up to 3 meters. When heating an area from 40 to 750 m2, electricity consumption per day ranges from 2 to 288 kW, depending on the modification.
3. The input and output of the EOU is mounted into the water heating system through plumbing couplings, adapters.The input of the EOU is mounted in the return line, and the outlet in the supply line of the water heating system. In the hot water heating system, in which the boiler is already installed, the EOU is mounted in parallel.
4. Working medium (heat carrier): water and non-freezing liquids for heating systems. Temperature at the outlet of the electrical installation: up to 95 ° C.

Registration with the Gostekhnadzor authorities is not required. The warranty period for the operation of the EOU is 10 years. The service life of the EOU is 30 years.

Installation of EOU

To install an energy-saving water heating device, fittings and connecting elements are used, which are traditionally used during plumbing work (pipes, hoses, couplings, adapters, etc.). The installation of an energy-saving electrical installation in the heating system is no different from the installation of other types of boilers:

• outlet temperature is about 95 ° C;
• operating voltage range 220–380 V;
• single-phase installation length 300 mm, diameter 43 mm, weight 2 kg;
• inlet connecting size G1 ″, outlet G1¼ ″;
• installation length of three-phase type 400 mm, diameter 106 mm, weight 7 kg;
• inlet connection size G1¼ ″, outlet G1¼ ″.

Possible mounting options

The inlet of the installation is connected to the return line, while the outlet is mounted to the flow of the heating system. If one or more boilers are already operating in the system, the installation of the energy-saving option is carried out in parallel with the existing devices. There are several options for installing the system:

• two-wire circuit with top wiring (natural water circulation);
• single-wire circuit with bottom wiring (forced water circulation);
• parallel circuit, when the ECU is connected to the heating system, mounted earlier;
• parallel circuit, when two or more EOU are connected to the system.

Mandatory requirements

When installing an energy-saving water heating boiler, it is necessary to provide for the installation of an electricity meter, in relation to the current strength from 1A. The cross-section of the electrical cable must have the same value as indicated in the instructions. The installation of the ground loop is also a mandatory requirement.

What to look for when choosing

During the selection of the installation, it is directed to take into account a number of factors affecting the normal functioning of the equipment. First of all, the calculation of the design capacity of the unit. Classically it is believed that for heating every 10m? a standard living space consumes an average of about 1 kW of energy.

For premises with a non-specialized area of ​​up to 200 m2, a single-phase electrical installation with an operating voltage of 220V is sufficient. In accordance with the above requirements, the total power of the equipment must be at least 20 kW.

Advice: for northern climatic zones or in case of an insufficient level of insulation of buildings, choose the total power with a small margin. So, for all the same 200m?, An installation with a capacity of 24kW would be the perfect option.

Any boiler must be equipped, at a minimum, with a protection system against short circuits or unexpected disconnection from the network, in addition, a pressure gauge is needed, showing the operating pressure in the system. It is perfectly recommended to install a special unit that allows automatic control of temperature and other operating parameters. The price for such a control unit is not so huge, so it is better to install it.

Energy-saving electric boilers for heating a house, in most cases, are small in size. But with the increase in the power of the equipment, in spite of the fact that it is insignificant, its dimensions nevertheless increase.

Wonderful three-phase units can be hung on the wall or installed on the floor. The best solution here would be to place such a unit in a closet.

Permits documentation

If it comes to single-phase, standard electrical installations operating from a 220V network, then no documents need to be drawn up. In addition, in the passports, these units are listed as household electrical appliances and are equated to simple heaters.

As for a three-phase industrial or semi-industrial installation with a voltage of 380V, then there are some subtleties. As a rule, no permission is needed here other than this.

But in some regions of our country, at the local level, certain standards may exist. Based on this, we recommend that you consult with your local Energy Supervision before installation.

Savings from the use of EOC

Energy-saving heating systems comply with all environmental and fire safety standards, operate silently, without emitting substances harmful to human health.

The use of EOU allows you to optimize the consumption of electrical energy, and where rationalism operates, the family budget is saved there. Thermostats installed in each room allow you to regulate the temperature in the range from 5 to 30 ° C. When the temperature drops by only 1-2 degrees, electricity costs are reduced by 5-6%. A more flexible approach to whole-home thermal management will result in 35-50% savings.

If desired, any temperature schedule can be programmed for a heating system with an EOC, according to which the automation will turn off one or a group of rooms.

Benefits of EOU

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

• profitability;
• compactness;
• autonomy;
• reliability;
• durability;
• no harmful waste;
• fire safety.

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

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

Examples of using installations

Energy-saving heating electrical installation - ideal for stalls and pavilions located far from heating mains.

The use of electrical installations will have a beneficial effect on the condition of old buildings in the historical parts of cities, where it is impermissible to carry out expensive and time-consuming work on the laying of heating routes. After all, such mansions and old palace buildings are often surrounded by magnificent parks. In such cases, energy efficient installations can be the optimal solution for protecting historic areas.

In city apartments, EOU can be used as backup equipment. They will provide a comfortable stay on cold days, which are not uncommon in spring and autumn when the heating is turned off. Russian winters are long and harsh, during especially critical periods when the centralized system does not provide adequate heat, the EOC will automatically warm the air to the required temperature.

EOU as a backup heating equipment can be used in large rooms with insufficient thermal insulation, for example, in warehouses, production halls, exhibition pavilions, concert halls and sports halls.
