Autonomous heatedthe artel mounted on the engine reduces the warm-up time to a few minutes. Many car owners will be skeptical to such a perspective. However, in practice, install the heater is much easier and more efficient than waiting for 10-15 minutes in a cold car.
Installing the heater for the engine 220V is not affected by the engine itself, but on antifreeze, significantly increasing its temperature. This is due to a tungsten spiral and a special block.
Preheater The engine 220V, connected under the engine, does not work constantly, but only until the engine is dropping its operating temperature. Then, with the help of the sensor, it turns off, and the motor continues to work in the usual mode.
Owners diesel engine Understanding the installation of the engine heating from 220V, since this type of motor is much more complicated at low temperatures. But on gasoline car Put heated can be as comfortable as for a diesel engine.
Another significant plus, for which it is worth connecting the heater, is saving gasoline and diesel fuel, as well as the fastest heating of the entire cabin, which is very relevant for the owners of leather seats.
Famous types of devices
Make an engine preheater with your own hands is quite possible if there are some skills and skills. But for a start, it is necessary to figure out what they are in serial production.
Fuel heater There are two types:
- autonomous;
- electric.
Installation of the electrical heater is considered simpler. It has a small cost, and its installation is very simple. It is based on a special block that heats the unit. It works properly connected engine heating from 220 V. Complete with it often:
- battery;
- system remote control;
- thermal sensor and timer.
The installation circuit of the electrical engine heater is very simple, so it can use it every car owner. The main minus can be considered only the amount of energy consumed, which is quite high for such a device.
Autonomous preheating of the engine, made with their own hands to set much harder. Its system is more difficult, the cost is higher. They are included using the button, do not require the presence of a power supply network. Autonomous heating installed from fuel system or from a special gasoline tank.
The basis of the work is based on the principle of air recycling, which allows the engine to start and quickly start moving regardless of weather conditions and the power supply network. The device warms the antifreeze, which then rises, enters the radiator, cooled and returns to the heater.
So the fluid circulates to the rees until he warms the entire system, and it will not reach the operating temperature. Autonomous heating connected to the cooling system can be installed in any place that freely under the hood of the car. And also he quickly carries out the salon heating.
Installation and installation of the device
Perspective does not wait for frosty in the morning. Extra minutes while the engine will warm, it seems very tempting for car enthusiasts. Many motorists at this stage will create a question, there is a homemade heating. And how to install the heating of the engine on their own?
To understand how to make the engine preheater, first will have to come to terms that it will work from electricity. Therefore, the presence of outlets in the parking lot will be one of the operating conditions.
So, the engine heater 220V assembled with their own hands will consist of a tan, reinforcement and several fittings. The TEN must be connected to a small circle of the cooling system and supply it to the pump so that the liquid can be circulated when the engine is turned off.
Installing the engine preheater has a fairly simple instruction, and for more convenience on the Internet there are videos, step by step explaning the course of action.
The first thing that will be required to collect and install the heater is a tee for an inch tube of a standard sample. It can be purchased at any store for the sale of plumbing, you can also buy a TEN, which will also need to collect your assembly. The best option will be a TEN with an already built-in thermostat for 1.5 kW.
The TEN is installed in the end of the tee, and a decade-cated tube is mounted on the other end. It is necessary for a faster heating system. On the free output and end of the pipe, plugs are installed for further hoses.
Now the resulting part is connected to the circulation system of coolant in the car. To do this, it is necessary to find the place of the hose break from the bottom, where the output to the stove is carried out, and to embed homemade device. The cable cross section is connected to the TEN contacts, and this first step can be considered successfully completed.
This is followed by connecting the pump with which the liquid will circulate. The easiest way will be used by the pump from the gazelle, as it is universal and has a fairly affordable cost. It is connected before the heater using an open relay to the network of a car or a regular outlet.
These are the main items for which the engine heating is made.
Danger of unverified systems
If you do not have absolutely no skills to perform such work, the best option It will be the purchase of a ready-made device. How to connect heated in this case will tell the instruction that is attached to the aggregate.
With independent intervention in the engine system internal combustion And the cycle of its cooling, there is a risk of damageing some elements in the event that you know the internal structure of the car.
If the desire to figure out and independently perform all the work too large, then you should enlist the help. Usually experienced motorist It may understand that part of the system where the heating is made and prompt the location of the necessary parts.
The easiest to use, but the most functional is the device for diesel engines of PZD. It is modest, but it works efficiently. Supports manual I. automatic startWorking with Tosol and antifreeze, on average power mode consumes less fuel liter per hour of work.
Pospz is able to withstand temperatures up to -45 degrees. You can install it yourself using the instruction or by contacting the nearest car service where this work will be performed in a few minutes.
Remember that any interference in the inner structure of the car must be qualified.
Before wondering how to establish an engine preheater in winter season, Consult the master. An experienced specialist will help determine which model is best suited for your car, model, year of issue and run, or it is not at all heated.
Each car is unique. And it's not a fact that the heater that is wonderful to the neighbor's car will also well reduce the time of warming the engine of another vehicle. Always relying only on the authoritative opinion of the specialist.
The climatic conditions of most territory of our country are distinguished by a very large range of temperatures: from heat in summer to chilling frosts in winter. In the summer, the operation of the car is quite simple, although it has its own specific features. And in the cold season, the car engine needs considerable time after starting so that its temperature reaches workers. And to facilitate the cold start and saving time, when you warmer the machine, there is an electrical heater of the engine, which for a rather short period of time is able to bring its temperature to acceptable values.
Engine launch features in the cold season
The internal combustion engine due to the characteristics of its design is able to develop the maximum of its power and torque in a rather narrow television range. That is why the cold start, especially in winter time year, so harmful to engines. Before, before the appearance of preheaters, single way It was considered to start and warm out at idle or increased turns. Now, with the advent of a variety of means and methods of warming up, it is possible to neglected. Especially since modern motors Very effectively distribute heat from the combustion chambers and quickly warmed up, thanks to which you can start moving almost immediately after launch. But this can be done under the conditions of the usual winter, and if at night the temperature reaches 40-45 degrees below zero? Here the additional heated engine is simply necessary in winter.
What is the engine heater
In the general case, the engine heating is carried out by artificially improving the coolant temperature so that it heats the engine parts (block and cylinder head, as well as the heater radiator). This makes it possible to significantly reduce the negative impact of increased friction force at start-up and local (uneven) heating of its parts.
Types of engine heaters
Actually, the types of heaters are only two - autonomous and electric. Autonomous heating, as follows from the name, does not depend on external conditions and is part of the automotive power plant: For its work, fuel from the tank is used. The most famous example is the autonomous heater of the Webasto engine. Special boilers with fuel combustion are heated by coolant, which circulates on the system - and all this without starting the engine.
The electric auto-heater is also embedded in the engine cooling system and with a special heating element, like a boiler, heats the coolant.
Electric heater as an alternative to standalone devices
The installation of a 220V engine heater is much easier (as it has, in fact, only one element and wires for connecting) and much cheaper, while it does not use gasoline as a heat source, bypassed electricity.
Varieties of electrical heaters
Block
The simplest type of heaters that are installed in the cylinder block instead of a block of side. They are an electric heating element in the housing and connector. Such models do not have a high power consumed (500-700W), but due to the fact that they are directly in the engine, it warms it almost in the center. More complex engine heating systems can be equipped with salon fan heaters, timer launch with remote control. The only problem in the installation can be the engine (crankcase ventilation hose), since it is often set so that overlaps the plug in the block.
Pipes
Such devices are installed in the incision of the main sockets of the cooling system. The heater itself is equipped with a special adapter body, which is installed directly on the hoses. The disadvantage is that most of these devices are designed for the standard diameter of the hoses. Such devices have a power may be higher (up to 2-3 kW), the functionality and the equipment is about the same as the previous group.
Remote
This is a special group of devices that are also embedded in the cooling system, but more complex in its design and installation. Such models are more similar to the "Webasto" heaters, only work on electricity, and not gasoline. Such models most effectively warm the coolant and the cylinder block. In the remote heater also exists forced circulation Coolant, which better contributes to the uniform warming of the cylinder block and reduces the discreet operation of the cold start to a minimum. The cost of such aggregates varies more than an order of magnitude (from 1.5 thousand rubles for ordinary Chinese models up to 23 thousand rubles for a really good American hotstart). The power of the heating element will also differ much and depends on the litter.
Advantages of engine heating 220V:
- Low cost Installation kit and installation itself (from 1 thousand rubles).
- Wide the lineup Compatible with almost all motors, simplicity of design and high efficiency.
Disadvantages of the electric heater:
- In the nearest accessibility there should be a household outlet for 220V.
- Outdoor hood during heating. On modern models, this is not so relevant because they are equipped with a special connector embedded in the front bumper.
- Reliability of some modelsWhich over time begin to skip the coolant coolant at the place of the joint.
How to put the heated engine
Installing the engine heating with their own hands - a relatively simple task. It will not require special tools and special knowledge. Only a general understanding of the principles of operation of automotive engines and an idea of \u200b\u200bthe location of nodes and aggregates under the hood is.
To understand how to install the heated engine, it is enough to look into the installation instructions attached to the kit. The overall sequence of installation is as follows.
- Since the heater is installed in the cooling system, it is necessary to merge part of the antifreeze (at least 2 liters to lower its level and prevent leakage during depressurization)
- In case of installation of a block heater, a plug from the cylinder block is removed And the heating element is installed. For remote or pipes, hoses leading to the heater radiator are removed. It is better to use hoses included in the installation kit so as not to cut the factory. When installing new connections, all compounds are fixed with the help of clamps, and the fittings are preferably wrapped with a sealant to avoid leaks.
- The case of the device is attached using a bracketcoming in the kit.
- All necessary connections are held.The rest of the assembly is carried out in the reverse order.
- Antifreeze poured back to the desired level. When filling, it is advisable to avoid the appearance aerial traffic (popping antifreeze in expansion tank Caution, fine trickle!).
Installing the engine heating is the task, quite satisfying almost everyone. And which type to choose, depends on the specific operating conditions and constructive features car.
The device specified in the title of the article allows the car engine or other vehicle without launching it. This device is used to preheat the engine, facilitating the engine start, and in some cases - and to warm the air in the cabin of the vehicle.
The importance of the engine heater in russian conditions It is difficult to overestimate. Especially relevant device for car owners with diesel engine. On numerous forums, it is often possible to read about the fact that the "wasolar". However, the owners of the car with gasoline engine Such a device also does not prevent in the context of the Russian winter. The heater brings the temperature of the oil to acceptable, and the car is easy to start.
Electric heaters
This type of heater is non-autonomous. This type of device invented in 1949 by A. Freimen. The invention is patented. The heater is screwed instead of one of the engine cylinders block bolts, it is powered by 220 volts. In some machines, such devices are included in the package.
It is clear that the electrical heaters are popular in the Northern countries: Canada, Scandinavia countries. In Russia, they are also used.
This type of heater is quite difficult. It has the following components:
- heating element. Usually, the power varies from 500 to 5000 W. The heating element is placed in a sealed heat exchanger, which is mounted in the technological holes of the engine cooling system, or is connected to the cooling jacket with the help of nozzles.
- Ecu with a timer. The timer is necessary to control the power on and off the heater.
- battery recharge unit, if provided for by the preheater design.
- the fan required for heating the cabin or open space Auto.
- there are models with POMPA, which contributes to uniform engine warming.
The principle of operation of the electrical heater is simple and based on the most famous laws of physics.
The heating element affects the coolant. She begins to circulate until completely warmed. The heating element must be installed at the bottom of the cooling system, since, according to the same physics laws, the warm liquid rises upwards, and the cold - lowers down. If the heater is equipped with a pump, then the placement of the heating element is not fundamentally.
Autonomous heaters
Autonomous liquid heaters are installed under the hood of the car and operate on one of the types of fuel: gasoline, DT, gas.
Composite elements of the liquid heater:
- a sufficiently complex control unit that controls a number of parameters: temperature, fuel supply, air supply;
- the pump that is responsible for fuel supply;
- air blower;
- boiler with fuel combustion chamber placed in it;
- a pump that is responsible for circulating the coolant;
- also, the system can be equipped with a relay that includes the cabin fan stove. In this case, not only the engine is heated, but also the interior, which is very convenient;
- timer, remote control or other heater control module.
The principle of operation of this type of heater is also sufficiently understood. The system starts remotely or with a timer. In motion comes fuel pump, pumping into the combustion chamber fuel from the car's tank, the other pump pumps air. With the help of spark plug, fuel is combined. The heat is transmitted to the coolant, which begins to circulate, thanks to the third pump. As soon as the liquid heats up to a certain temperature, the cabin fan is turned on. Begins to warm the car's interior. If the coolant is heated to a high temperature, the system is turned off.
The average fuel consumption for the use of such a heater is 0.5 liters of gasoline per hour. It is better to spend money on gasoline than in the morning "conclusion" from the car with a soldering lamp and other handicrafts, trying to start the car.
The disadvantages of liquid heaters include the following: in its work the system uses the energy of the battery installed on the car. If the battery is weak, then the liquid heater can "plant" it completely, and the car is not started in the morning.
In general, this type of heaters does not have serious shortcomings, but has great advantages.
Heat batteries
Toyota Prius is equipped with such devices. What do they imagine? The thermal battery is a thermos in which a certain amount of warm coolant is assembled. When the engine starts, the collected liquid is injected into the cooling system from the heat battery. On average, the temperature of the entire cooling system fluid rises by 10-15 degrees, which makes it possible to operate the engine without a special load. By the way, thermal batteries can maintain a cooling fluid in a warm state up to 2 days.
Obviously, the method has the right to life. Moreover, when using such batteries, it is not necessary to additionally spend electricity or fuel.
Heaters diesel fuel
As mentioned at the beginning of the article, diesel fuel is not very good friendly low temperatures. Therefore, for dissolving paraffins formed in Dt, heaters also use.
Diesel fuel is heated by two types of devices: some of them are attached to the filter of DT cleaning, while others are on the fuel system highway, or they are cracked into it.
Popular model of preheater
Webasto Thermo Top E
People who are even a little interested in cars, probably heard the name of Webasto. Yes, this is perhaps the most popular brand of heaters.
The thermo top E model is an preheater heater, that is, it warms the coolant, engine and air in the cabin. Produced in Germany, like other products Webasto.
Thermo top E is a classic example of liquid heaters that have already been discussed. The device is relatively compact, suitable for installation even in small classes in cars. It is important that even at the time of its start, the heater consumes a very small amount of electricity. Thus, for the charge level of the car battery does not have to worry.
The upgraded version of the heater timer allows you to turn on the heating device at a time from 10 minutes to 1 hour. When frost at 10-15 degrees, the heater may well cope with its task in 15 minutes.
In the hot season, the heater is able to air the car's salon, which is also very nice, especially for owners of those cars in which air conditioning is not installed.
Everything is good in Webasto, except for the price. Not every Russian car owner will decide to spend on the heater of this company.
Teplostar 04TS
Teplostar is a domestic heater, which is produced in Samara. The model, in general, is very good. With the help of 04tes, the coolant and the interior is heated, there is a remote control that operates at a distance of 150 meters. That is, if the car stands under the windows at home, then it is not difficult to start the heater with the remote control. The console has only one minus: it is not equipped with a system feedback. There is a danger that, if the heater gives a failure, the owner of the car learns about it only in the morning, sitting in a cold car.
It is gratifying that Samara manufacturers of heaters were given special attention security device. Before starting the ECU checks the performance of all systems. If something works incorrectly, error codes are displayed on a special display. If for some reason burning in the chamber ceases, then the fuel supply is stopped. This is very important and valuable.
Severst 103.3741
Severste is a heater, which is also produced in Russia, but it is non-autonomous and runs from a voltage with a voltage of 220 V. The device has a thermostat that protects against engine overheating. Heating up to 60 degrees is carried out in 1-1.5 hours. At a temperature of 85 degrees, the system stops working. If the coolant temperature drops to 50 degrees, the heater again starts its work.
It is noteworthy that the heater has protection against moisture and from electric shock.
The disadvantage of Severse is just that he needs a socket. For car owners having their own garage, the device is suitable very well. But for the rest it is unlikely.
Defa Warm Up.
Nonavonomous heater, which is produced in Norway. Heats the engine, interior and, attention, can recharge rechargeable battery. The latter is very important, since in the cold the car battery significantly loses its power.
It has basic and universal sets that can be combined at their discretion.
Compared to the above-described heater, Severs, Defa, of course expensive. But the price justifies the functional set.
Autoplus Madi USD -0.2-2
The device from the firm autoplus is a thermal battery. It is easily installed on the car of any size. All the operation of the device is automated. The driver does not need to make any manipulations. It is noteworthy that installing a thermal battery on a car any car owner can independently. No special skills are required here.
Nomacon PB.
Nomacon is an preheater diesel fuel. It is mounted on the filter thin cleaning. In fact, there are no competitors to this heater in the domestic market. But Belarusians hold enough low prices On the device, while maintaining and high quality equipment.
RESULTS
Having considered the types of preheaters, having familiarized themselves with their basic models using popularity, one simple conclusion can be made: in Russia, it is possible to use the pre-heaters. What exactly? Solve each, based on preferences, such as a car and budget.
Often in winter drivers face a lot of difficulties. And the main one is not always the perfect launch power aggregate. To solve this task, a special device was created - the engine preheater 220V with POMPE. Such a device is not easy guarantee a stable motor start under all weather conditions, but also to reduce exhaust harmful emissions in environment. Some of the models of electrical heaters due to their action allow you to save a decent amount of fuel. In addition, friction between the elements of the engine is significantly reduced, and therefore the most gentle details wear much slower. And this is the best way to affect the working qualities of all auto units.
Such a device is an ideal option for motorists living and operating vehicle in cold climatic regions where engine launch problems in frosts are always relevant. But the car owners living in the regions with a softer climate often install the heated engine 220V with a pump for use in frost.
Auto-heaterIn the 80s of the last century, the release of such devices at the industrial level was not yet so actively established. Therefore, many motorists have attempted to make electric heating on their own. At that time, in special stores it was possible to purchase a pallet of the Carter to the Moskvich car, which was equipped with an electric heater, mounted directly into it.
If in the past it is possible to talk about single attempts to manufacture electrical heaters, then in this many manufacturers an industrial production of such devices has been established.
The number of cars every year significantly increases and most of them remain "spending the night" in the open air - parking lots, parking in the courtyard at home and other not adapted for this place. Therefore, it can be argued that the relevance of the use of the engine preheater for them is not lost, especially in frost.
Important! Apply an open source of fire or household heating devices for heating and further starting the engine in the frost is unsafe, as it can lead to a fire.
Details about car heaters
Device and scheme
The device of the auto-electro-heater
The electrical heater is a tubular heater placed in a metal housing. It consists of the following elements:
- At the bottom of the design and the top cover of the device are located gaskets-compactors.
- Special temoregulator The temperature mode is monitored inside the system.
- Electromagnetic pump (pump)operating from the electric drive.
- Rubber ring Under the base of the pump.
- Impeller At the bottom of the electric heater, with the flange attached to it.
In addition, there are 2 removal in the housing, with which the connection to the cooling system of the power unit is connected. Due to reliable sealing gaskets in the device, all sorts of leaks are excluded. And, as mentioned above, the work of such a device does not throw in the environment of harmful substances.
The principle of operation of the electrical heater
Typically, auto-heaters are put in the cooling system of the engine. At the same time, a coercive circulation of the cooling composition with its simultaneous heating is carried out. Thanks to this process noticeably Engine heating is accelerated to optimal operating temperatures..
Scheme of heater The electrical heater begins to work when connected to the power supply with a voltage of 220V. That is why it is advisable to leave the car where it is possible to connect the device to power (with the help of extension cord or other means). After connecting the device, a tubular electric heater starts to work, the main task of which is to increase the temperature of the coolant. Heated toosol / antifreeze with pumps is supplied to the cooling system. In addition, the impeller is also involved in the supply of heated fluid.
This ensures continuous circulation of the coolant inside the system. At the same time, the warming of the power unit is uniformly, but not fast. The thermostat controls the permanent maintenance of optimal temperatures and, if necessary, they open the contacts, which leads to the termination of the supply of electricity to the device.
Package device
Standard the preheater preheater kit contains Special bracket (1 piece) and fasteners (bolts, nuts, engraving and ordinary washers). To improve fixation, the device is also equipped with an intermediate sleeve. To connect the tee to the cooling system, fittings are attached with marking (for example, in a modification designed for voltage 220V, the Marking of K14 is the diameter). To protect the device when installing installation work, nylon elastic homethers ("worm" and for a screed) are supplied to the preheater. In addition, some models of electrical heaters are equipped with a sleeve of small sizes.
Grade heater What affects the power of the electrical heater
Power this device directly depends on the limit frequency of the device. As a rule, this value is 50Hz, although there are some deviations. In addition, in the calculation you need to take the diametrical size of the piston, which directly affects the circulation rate of the heated fluid.
In this case, the operating power indicator determines the optimal temperature set time: the higher it is, the faster the heating process occurs. As a rule, the coolant is heated to a temperature of 60 ° C per 3 min.
And yet, at the power of the preheater, which should be well strengthened and not exposed to blowout, affects its location.
Installing the preheater
Before starting to install it is necessary to carefully examine the scheme and device cooling system His car. Since it affects the method of mounting the electrical heater. In addition, much will depend on the modification of the device itself, but there are general rules for installation.
Scheme installation of heater First, it is important to understand that the device must be connected to a single-phase network.. And be sure to ground contact. This is done using an automatic shutcher having protection against electric current. Some recommended when installing the device to use the shutdown system. This device makes the process as safe as possible and reduces the risks of lesions by the current when performing work.
Remember! Any closure of wiring often becomes a cause of fire. Knowing this, during the work should not be touched by uninsulated equipment.
Starting the installation of the electrical heater, it is necessary to inspect the cooling system. The device is practical always connected from cylinderswhere it is provided with a pipe with a diameter of 20mm. Place the device in a horizontal position. As a result, it should be lower than the level of the radiator. This must be done to exclude the enclosure of the device. We clarify that if necessary, the installation site of the electrical heater can be changed, but this will require an additional hose (usually included to the device it includes). After joining the device, it must be secure on the housing. Although, sometimes, it is quite difficult to implement it.
A gross mistake is considered to fix the preheating on the silencer collector. Since it is unsafe and leads to the fire of the vehicle.
In principle, installing this device is not too complicated, but, having even minimal doubts about the correct implementation of all actions own forces, it is advisable to contact the masters of the car servicethat will make all the work quickly and efficiently.
Automotive electric heater Key features of the electrically heater
TO the most important characteristics Preheater the following indicators include:
- Power - Unit of measurement of this value of kW. For example, a modification with an indicator of 1.5 kW will heat the coolant for 3.5 minutes. And the increase in power up to 2kW allows you to get the necessary temperature for 3min.
- Another one an important indicator is an type of electric current and its maximum frequencymeasured in Hz. The temperature value of the thermostat is depends on this indicator.
- The value of the circulated flow measured in l / s. It depends on the diameters of the input and outlet holes. Usually nozzles have diametrical size 12mm.
- But in the sizes of the device itself strong differences are allowed. On average, the device has a length of 15 cm, width and height of 9cm.
It is advisable to mention the classification of the degrees of the system protection system for the preheating device. For example, the most common models have label "IP 34". This indicates that the device is safe when operating, and short circuits in the network are excluded.
When buying an electric heater for a car, you must pay attention to the forks. Today almost everyone russian manufacturers Such devices equip their products with an element made according to the Eurostandard. The average mass of the device is 1kg. Note that a good preservation device with a pump running from a 220V network has a price of 4000 rubles.
Preheater In addition, the device can be added a variety of highly useful equipment. Suppose you can put the start timer, remote control, recharging the battery, fan heater to the cabin, etc. But it will cost more than 25,000 rubles, not counting the installation costs.
About advantages and disadvantages
Benefits of electrical heaters
- for a long time - Due to low power, the device does not need constant control (it does not harm it, so it can work without a break and 8, and 12 hours);
- operating safety - Usually, a special thermal insulation material is included in the device, which protects insulation and located near the wires from melting, in addition, it prevents the spread of energy, increasing the efficiency of the device;
- easy when installing.
Preparation electric heating Disadvantages of electrical heaters
The main minuses of such a device is for a long time of heating and dependence on stationary power supply in 220V. For example, at a temperature of 0 ° C overboard the car, the device having a power of 600W will warm up the engine approximately an hour, and if the temperature drops to -8-10 ° C, the heating time increases to 2 hours. At the same time, buying a budget device with a capacity of no more than 500 kW, the motorist should be ready for a longer heating time.
The electrical engine preheater is a mechanism that allows you to warm up the car engine without launch.
Such a need arises in cold weather. The operation of the heater simplifies the subsequent launch. Sometimes this device is used to heat the cabin.
The principle of operation of the electrical preheater
In contrast to autonomous heaters, electric work directly from the 220 V network (from outlets in parkingons, in parking lots).
The heating element warms the coolant. The temperature distribution occurs when the warmed liquid rises upwards.
The device is automatically shut off when the specified temperature is reached, i.e. It can be left included in the parking lot overnight without hazard overheating.
