Only Imagine this: stuck plug into the socket - and not afraid of cold! But if you think about it, nothing unusual here is not - a device and principle of operation of such heating systems are based on immutable physical laws. But it is certainly not the only one pot (it only serves to heat the working fluid). Still require heat transfer elements - the battery, connecting pipes, other details, such as a steam heating system, Yes, and the kettle is strictly speaking - no kettle and the pot of Tan. But in terms of it and in fact almost indistinguishable from a home appliance.
Current model of such a boiler, among other exhibits were presented at the National Exhibition of technical creativity of pupils, held at the XII All-Russia rally of young technicians in the city of Volgodonsk, Rostov region in the summer of 1995. And came up with a boiler Dmitry Governors - member of the circle "Space Simulation" (Settlement, goose Smolensk reg.), Where his project guys and implemented under the leadership of Nikolai Ivanovich Khlebnikov.
As conceived by the founders of the boiler is for use in a heating device and heating systems (see photo). With the use of batteries that are filled with water or oil, it is designed for around the clock to ensure a warm 14 - 16 standard battery of registers.
Power 1 kW heater. But provides automatic boiler economical consumption of electricity, maintains the desired temperature of the liquid with protection against overheating and prevents the inclusion of the boiler at its absence. Simple and reliable design allow you to use and maintain the boiler even unskilled staff on all sites. Yes More than heating, it can be used to heating oil and lubricants.
Designers used a standard boiler heater factory production, calculated at 220 V, mounted it in a makeshift enclosure (Fig. 1). Dimensions of parts of the last arbitrary, because the critical values do not have. However, calculations show that the volume of the chamber of the boiler should be possible to minimize, which will contribute the most rapid exchange of fluid in the heating system. This is especially important to achieve its maximum efficiency and economy - in fact in large boilers much "Extra" water is heated in vain, which leads to waste of energy and therefore reduce efficiency, since heat exchange with the surrounding air occurs in mainly in batteries, and not a boiler.
In fact, in theory, the boiler itself, and can be eliminated altogether from the system, and instead mount a heater directly into the connecting pipe, as shown schematically in Figure 2, this section of the pipe must be, of course, removable - for ease of maintenance, preventive maintenance and service. However, a detailed analysis it is easy to conclude that such a device is some semblance of a boiler, just very very tiny and with its own peculiarities. Shall not discuss them in detail - you'll find them yourself, carefully Having examined the pattern (do not forget that this is just the scheme). A little thought, it is easy to find conclusive advantages and possible disadvantages of this design and see that it does not differ from the boiler Gubernatorova-Klebnikov. And emphasize how this technical solution is close to ideal.
theoretical refinements, however, leave and return to practice. For a boiler connected tightly enough to combine it with a working volume of the heating or a heating system (battery, fuel tank with oil), filled with a liquid volume of the boiler. Then connect the automation unit (Fig. 3) to the network 220, and plug the boiler - to the connector block. If, in the slot of the boiler is not installed board sensors or connector is not connected to the automation unit - the boiler heater turns on. Do not turn on it and in those cases where the cavity is not sufficient liquid level tank when its temperature reached a certain limit or when the adjustment is set potentiometer on too small a value.
With the potentiometer to set the desired temperature of the liquid, which can be controlled by either a user-friendly site heating. Temperature readings can be recorded, for example, electronic thermometer directly deliverers thermostat is required only correction of the adjustment potentiometer temperature of the boiler.
Note that if boiler provides a low temperature, the flow regime is necessary to reduce the intensity of liquid flow in closed mode, adjust the temperature K2 regulator, and if more - to increase the flowage, adjusted R2. And do not forget that the overheating of the liquid to the vapor state is not allowed! When
use of the boiler must, of course, comply with basic safety requirements: before commissioning him to earth for the terminal on handset sensors or drain tube and when repairing or disassembly - unplug.

Cauldron given design tested within winter 1994-1995 year for heating individual house with dwelling premise area 32 sq.m. And only spring internal surfaces were cleaned descaler galvanic way. And to reduce scaling, the system should be completed well boiled, and best of all - with distilled water.
From this cauldron of existing designs favorably differs insignificant consumption electricity opportunity nutrition from household mains, contactless regime preheating fluid small dimensions, stepless and accessibility manufacture.
