Reasonable approaches and key schemes of electric heat energy generators explain the variety of power options for this type of heating equipment. In addition to the classification according to the type of power supply network for 1-phase equipment and 3-phase boilers, thermal transformers are divided into the following varieties:
- TENOVye. The circulating carrier of thermal energy is heated using the interaction of a liquid substance with thermoelectric glow components in the unit compartment.
- Electrode The resistance of the saline solution (plays the role of an electrolyte) when conducting alternating electricity through it is accompanied by the formation of heat, which is transmitted to heating batteries (insulated flooring).
- Induction. The selection of thermal energy is carried out from a kind of converter with a primary and squirrel-cage (secondary) winding.
Energy Direction Conditions
The declared capacity of electric heating equipment for private sector housing varies between 1,500 - 36,000 watts. Such a consumable load on the electric network requires a special separate line for connecting the transformer. Supply wires to it are laid directly from the reading device - an electric meter. For emergency or planned disconnection of the energy source, circuit breakers are used, which simultaneously play the role of a fuse in case of short circuit. It is allowed to connect to the electric network with one phase of electric boilers with a capacity of up to 9,000 watts. Stronger selection devices operate on 3 phases. It should be borne in mind that the unit must be connected to the mains that has grounding.
How to prevent excessive temperature changes of the media
The use of electrical sources of thermal energy in water heating circuits is fraught with the threat of boiling coolant. In this regard, the equipment almost does not integrate into the gravitational structures of heating private housing, but is installed together with circulation pumps that promote circulation of the thermal energy carrier. During installation, the eyes on the thermostatic device responsible for the activation / deactivation of the heating device in automatic mode are especially sharpened. The thermostat switch is also able to function as a guard against excessive temperature drop in the unit in the situation when the energy source is used as spare technical equipment.
Water heating safety
Uninterrupted circulation of the functioning of electric boilers, safe use requires installation of special security structures in the heating circuit. Such devices are installed separately or are combined into a security category represented by the following components:
- Automatic damper for discharging air flows from the water circuit.
- A protective (safety) shutter in the form of a membrane to remove excessive pressure from the structure in case of failure of the thermal energy regulator or the occurrence of congestion in the pipes.
- Pressure gauge. Regulating measuring device necessary for external inspection and observation of the position of the functional environment in the circuit. In some cases, instead of this device, a combined device is used that reflects, in addition to pressure and temperature, the carrier of thermal energy.In the scheme of isolated (closed) heating, it is mandatory to install an expansion tank with a volume that helps to compensate for a linear increase in the total size of the thermal energy carrier in the structure.
Connection to the water supply of the technical equipment of the heater
Long-term (seasonal) use of heating, one way or another, contributes to a decrease in the number of liquid substances in the circuit. To eliminate this phenomenon, the water supply should be connected to the structure of the room heating. The connecting pipeline is usually equipped with a pair of ball valves. Between them mount devices for the preparation of water (for example, a filter device filled with polyphosphate salt). The filler chemically prevents the formation of salt deposits on the glowing components of the heating device. It should be noted that the efficiency of electrode heating units is determined by the amount of salts in the mixture for electrolysis. In such a situation, the preparation of water is accompanied by a procedure for enriching a liquid substance with salt. The installation procedure for electrical equipment for heating is not signed by the monitoring institutions. It is only necessary to agree on the provision of facilities for technical equipment if its consumption exceeds the limit specified in the agreement.
Optimization of payments for electric current, the price of which varies day and night, explains the improvement of the node for tracking consumed electricity. Mount a meter with 2 or more gradations of payments for electricity. Every 30 days, the cost of heating with electrical equipment when applying urgent tariffing is significantly reduced. The connection of an electric boiler to the heating structure can be done with your own hands, but if you want to connect correctly, you have doubts about your own abilities or you simply don’t have enough time for this, then this work should be placed on the shoulders of installation companies that specialize in this kind of activity for a long time . To be sure of the efficiency of the device itself, electric boilers should be purchased only from trusted manufacturers.
