In the current environment, when technological progress does not stand still, and the traditional heating methods come to the fore. Many of us who have a private house or holiday house out of town, try to choose the most convenient, most efficient and economical way of heating. Gas water heating is now considered the cheapest. However, not always for some reason, you can connect to a central gas supply. A great alternative to gas heating solid fuel boiler will be working in tandem with elektrotenami. This combination of fundamentally different heat sources caused by technological necessity.
Modern radiators for solid fuels are high-precision device. Solid fuel boilers are powerful, economical, able to simultaneously solve several technological problems. Despite a lot of obvious advantages, even the most advanced models of boilers for solid fuels are not without drawbacks. We consider in detail, why and for what purpose are available with solid aggregates elektrotenom.
Solid fuel and electricity - the background of such a combination
All of us are very familiar situations that arise in the operation of boilers in a private home. In centralized gas supplying human factor is reduced to almost zero, while the operation of heating equipment for solid fuels requires constant attention. Solve the problem of installing a single automation, will not succeed.
Excellent technological capabilities, cost-effectiveness and practicality of use, features that are now deservedly can give solid fuel heating units. All anything. However, there is one major drawback that can cloud idyll and comfort in your home. Run out of fuel, burned wood in the firebox, so what? The boiler is forced to involuntarily stop. If there is a heat accumulator, the situation is not as catastrophic. Stored in the hot water tank will disperse to the heating system, maintaining for some time, the desired temperature in the building.
And if we are talking about the suburban home where the visit took place between the owners a lot of time. Stopped boiler dissipated heat transfer fluid from the storage tank will put the entire system in a technological collapse. In winter, this situation is fraught with the unfreezing of the entire heating system - emergency, whose consequences are eliminated in a short time will not work. What would you like whatever happens, use a fallback heating the coolant in the system. The role of a fuse in this case it is best to entrust the electric heater. Electricity network is almost always, regardless of whether there are home owners or not.
Important! Boiler for solid fuels carries out the bulk of the coolant heater, providing hot water the inhabitants of the house. The results are achieved by high-power equipment and features solid strapping units. Electricity in this case assigned support role. Electric part has a limited capacity.
Electric heating elements are able to maintain operability of the heating system at the optimum level. Ended in the furnace of firewood, the system switches to the power supply. There are cases when both the heat source working in tandem, in turn, replacing each other. We are well familiar with the situation when the night burns firewood next tab, and in the morning the house begins to cool and hot tap water lukewarm.
What is a solid fuel boiler, equipped with electric heating elements
Faced with the phenomenon of defrost heating systems, with reasonable've found a technical point of view, an engineering solution. Producers have decided to equip a conventional heating device running on coal or wood burning, electric heating elements. This upgrade was made possible thanks to the peculiarities of the heater design.
The basic operation of the boiler is carried out by burning the fuel that is embedded into the combustion chamber. Due to the combustion boiler is in operation, supplying heat and house providing operation MAN system. Above the combustion chamber a heat exchanger, being a basic element of the whole structure. Unlike conventional solid vehicles, this technique has one, usually two or three thermoelectric heating elements - electric heaters. Such devices can be installed directly in the heat exchanger.
In normal circulation of coolant through conduit carried by gravity or forced by a circulating pump. Once the intensity of the combustion in the furnace is reduced, decreasing temperature of the coolant in the system, which is signaled by the temperature sensor. Included in the work electric heaters, reporting is necessary to cool the heat transfer agent. Accordingly, in view of reducing the intensity of heating, boiler water circulation system is slowed down.
Thus, in a nutshell you can describe the working principle coal-fired boiler with electric heaters.
On a note: Many options for installing electric heaters. In each case, the manufacturer itself determines the optimal version of the heater structure. From electric heaters location depends directly on the end result.
The advantages of solid-fuel units with electric heaters and disadvantages
Conventional boiler with wood or coal, installed in your home or at the cottage all is well. There is only negative, which the owners have to hold back. The problem is the continuing need to feed the heater fuel. Electric heaters installed in the boiler, can dramatically improve the situation by taking over part of the work in an infinite process. With these devices you do not have to regularly go and see the boiler room and control the combustion process.
Important! Count on the full heating of residential buildings and provide hot water at a working electrical heating elements, it is not necessary. Electricity in this case a temporary heat source. Allow big breaks in the main part of the boiler, then put yourself before the fact of the high costs for the consumed electricity.
What are the benefits you get by installing at home a combined solid fuel boiler:
- autonomous work throughout the home heating system;
- increased time interval between loading fuel into the combustion chamber;
- water heating systems protection from freezing at low temperatures.
With regard to the technological advantages, the solid units equipped with electric heaters, have the following features:
- no formation of condensation on the internal walls of the combustion chamber due to constant heating coil electric heaters;
- with the continued support of necessary temperature of the coolant, it is not necessary to mount a spare circuit and put termosmesitelny valve;
- by operating the electrical appliance, the heating efficiency of coal-fired boiler rises to 95%.
Universality is the main advantage of such a technique, however, such benefits have a downside. A combination of both types of heating elements in a single device leads to a significant increase in the cost model. Compared with traditional solid-fuel units, such boilers are much more expensive. However, if you want to get peace of mind and comfort, the price will not be a deterrent.
A second aspect that may deter consumers from such boilers consists in device manufacturability. Large inertia of the boiler is characteristic for both the solid aggregate, and for its electrical part. Low power electric resistance is the main factor hindering your choice. Typically, when the main power of 50 kW or more, electric heaters give all 6-24kVt. As a rule, the total power of the electric thermoheater no more than 1/3 of the maximum capacity of coal-fired boiler.
On a note: Boilers equipped with more powerful electric heaters, are more expensive, and power consumption in this case is significant. Such combination boilers are convenient to use, but it is not cost-effective as a heat source for heating the system.
Conclusion. Hook Up Special Features
The acquisition of the solid fuel boiler, equipped with electric heaters allows you to immediately solve almost all the existing problems with the heating system.
The main thing! To supply electricity such units do not require a conversion of a home electrical outlet into three phases. The only condition for the proper operation, compliance and connectivity standards. The boiler at the time of operation of the electrical part works as a normal storage heater from the home network 220.
This technical possibility does not give the right to relax. When connecting the boiler to the system should be a separate line with a cut-off machine that boiler protection against unauthorized connections to the lines of other electrical appliances. All additional manipulation during the installation of the boiler on solid fuel with an electric part, consist in the laying of a new cable and connection.
The special features of the operation of such heating technology relates arrangement chimney. Good traction allow the boiler to operate normally in the combustion regime without provoking unauthorized switching electric heaters. The quality of ventilation and extraction determines the operation of the entire heating system. Have a craving, burning fuel, there is no draft, there is incomplete combustion wood heater starts to work.
By its dimensions heating technology of this class is not much different from conventional counterparts. The same size of the combustion chamber, the same volume of the heat exchanger. The heating system with the solid-aggregate in the construction of which electric resistance are present, also implies the presence of heat storage, and other security devices.
