Preheater - the best engine protection from frost. Preheating: three methods of the engine preheater 220V which to choose

Many manufacturers of foreign cars, orienting the sale of their cars on the Russian market, offer models with an installed autonomous preheater engine and a cabin. This option is especially valuable in the regions with a long winter season. It is not necessary to defeat those motorists who, who do not have machines are not equipped with the engine's factory preheater. Buy it and establish on any brand of the car currently does not represent problems in any region of the country. The question is more important here about how effective is the equipment and whether it is worth the costs that are necessary for its acquisition and installation.

For this, the engine preheater is needed in winter

What does the preheater consist of and what

Depending on the purpose and principle of operation, the preheater may be a device of various dimensions and power used to heat the engine without its cold start. In addition, it can be used to heat the cabin, windshield and janitors. Offline equipment includes a boiler with a combustion chamber and a radiator, a pipeline system for transmitting fuel, pumps that swing fuel and coolant. It also includes a thermoster, controlling the climate-system fan, an electronic control unit and a device for starting the heater.

Liquid Preheater Thermo Top

Types of automotive preheaters

1. Autonomous engine preheater

For purpose and device Autonomous Preheaters divided into liquid and air types.

Autonomous Liquid Preheaters

Video: Webasto or Hydronic (Webasto or Hydronic) What is better

Designed for heating both the engine and the cabin. They are called so because they work through the burning of gasoline or diesel fuel from the car's tank. They are mounted in the engine compartment and connect to the liquid cooling system of the motor. Heated air applies to internal car ducts. The system is economical on fuel and electricity consumption, during operation does not produce strong noise. It is used for heating all types of internal combustion engines - gasoline, diesel, gas and combined.

Autonomous airborne prehea heaters

Designed for an accelerated increase in air temperature only in the cabin. They are installed in the car's cabin and are used mainly in passenger minibuses, wrappers and kungahs, freight "long-range" machines. They can heat the air in the cabin to a predetermined temperature. Also working silently and consume some electricity. Unlike liquid devices, air devices have large dimensions and performance, so the fuel consumption is somewhat higher. The most popular in the country such brands of German production heaters like Webasto Thermo Top Evo 5 and Eberspasher Hydronic.

The principle of operation of the liquid preheater engine

This works autonomous liquid engine heater

The device is turned on to work from a remote control, timer or cell phone. Startup pulse, falling onto an electronic unit, produces a control signal that feeds the supply voltage to the actuator engine. Motor, rotating, leads to a movement of the heater and fan fuel pump. The pump begins to swing fuel in the burner, where the fuel-air mixture is created using the evaporator and the stubble pin.

The combustible mixture is injected with a fan flammable in the combustion chamber of the spark spark plug. The heat formed during the combustion of fuel, through the heat exchanger is transmitted to the working fluid of the engine cooling system. The liquid circulates in the cooling circuit under the action of the puming pump of the preheater included in this circuit. The heated liquid in the circulation process transmits the engine the heated housing.

When the coolant temperature is reached, 30 degrees with automatically triggered the car cooling radiator fan. Begins to enter the salon. When the toosol or antifreeze is heated to 72 degrees with a reduction in fuel supply to the burner half, and the system goes to a reduced operation mode. The liquid is cooled to 56 degrees and the entire process is cyclically repeated.

By design, the liquid autonomous engine preheater is similar to the cabin automotive heater and is a burner on liquid fuel (gasoline or diesel engine). Even in terms of cost, they differ slightly, not to mention the principle of work. However, at the place of installation and the principle of heating, they are fundamentally different.

In heaters, the burner heats directly the air supplied to the car's salon, and in the preheater, it warms the coolant, which, in turn heats the engine and the standard stove. In order to effectively work the heating of the cabin, it is not necessary to forget the installation of the handle of the stove control on the minimum mode "heat". In this case, the control circuit of the heater at the desired moment will automatically turn on the fan, pumping the warm air into the cabin on the standard air duct system. The result of this work will be noticeable from published, the car's windows in the frost morning will be dry and transparent. In the cockpit, it will be warm and cozy, the wipers can not be removed overnight, it is possible to sit down and immediately go to the road.

A convenient function is remote control of the operation of the pre-heater of the internal combustion engine. It can be enabled using the key on the keychain with the keys from the machine while at home. It is necessary to do this at least half an hour before departure (depending on the frost on the street) so that the cooling fluid and the motor do to warm up to the desired temperature, and the engine start process has passed without complications. There are systems with automatic starting from the built-in timer, on which you need to set the desired inclusion time before locking the machine.

2. Electric Preheater HEAT

Device and diagram of the electric heater engine

An alternative to the autonomous system is an electric heater, which is a spiral electric heater inserted into a power unit cylinder block and operating from an external power supply 220V. The executive element in this system is a small electrical spiral, installed in the cylinder block.

From the block of cylinders when installing the spiral, the silt-made plug is removed, the helix instead and is mounted. Under the action of high voltage through the spiral flows, and it heats the antifreeze. The circulation of fluid in the cooling system is due to the natural convection. It is less productive than with the artificial handling of the pump, and takes a much longer time. The most vivid representatives of the electric heater are the Defa Warmup models and the Severste leader.

The most acceptable is this installation when parking cars in garages and parking, equipped with electrical outlets. If you leave the car on the street or in the courtyard, then you will not need such a heater, as there will be no place to connect it. The disadvantage is that it consumes a lot of electricity. To ensure economical operation of the device, it is equipped with a timer that allows you to establish the required fluid temperature.

When you go to the installed, the helix is \u200b\u200bautomatically turned off or turns on to work. Accordingly, it occurs cooling or heating the working fluid, which in the process of convection supports the motor in warm condition. The standard options of the motor electrical heater are:

• heating the working fluid in the cooling system of the motor;
• salon heating due to the supply of warm air through a standard stove;
• battery charge.

The principle of heating the motor in the electrical heater is the same as in the autonomous system. Heat transmission is also carried out by heating the working fluid in the cooling system. The difference lies in the method of heating using an external power source. This makes it possible to apply an additional option -, which is particularly in demand in winter conditions, when low temperatures contribute to its discharge and lowering the capacity.

3. Thermal batteries

The principle of operation of thermal batteries is based on the accumulation of hot working fluid in the cooling system and preserving its temperature unchanged for a long time (2 days). In such a system, when you start a motor, hot antifreeze or antifreeze performs a short circulation along the abbreviated circuit, quickly warming the engine. Classical representatives of such systems - "AVTOTERM", "GOLFRIM", UOPD-0.8.

What gives the use of preheaters

Professional drivers recognize the presence of an autonomous or electrical preheater of the motor with a prerequisite for the configuration of a modern car that guarantees the necessary healthy working conditions in the winter period of operation. For trucks operated in Europe, this principle has been respected for a long time. From the point of view of security management, their use contributes to the improvement of comfort and reduce the driver's fatigue. Among other things, the heaters contribute to improving the economy and durability of motors. This is achieved at the expense:

Video: Engine Preheater

1. Reducing the number of "cold" engines. It is estimated that on average, each driver produces from 300 to 500 "cold" launches. At the same time, special studies in this area, produced by famous European companies, it was found that in recalculating one "cold" launch, the use of preheating of the motor reduces fuel consumption from 100 to 500 ml. The value of savings depends on the temperature of the outer air and the duration of the heating. Thus, by rough calculations, the use of preheating from autonomous heaters allows saving in one winter season from 90 to 150 liters of gasoline or diesel fuel.

2. Reducing heavy operation modes that increase engine wear. The overwhelming proportion of the engine wear falls on the period of its launch. This is due to the fact that at the moment of "cold" launch the viscosity of the engine oil is increased and lubricating properties are lowered. At the same time, the friction of the surfaces of moving parts increased and increased wear in connecting rod crank and piston nodes. One "cold" launch reduces the resource of the power unit by 3-6 hundred kilometers of the mileage. Russian climate with 100 days in the year of minus temperatures can give a reduction in the engine resource in one season for 80 thousand km.

3. Enhance security and comfort in driving. The cold contributes to the increased heat transfer and fast fatigue. Driving and lethargy increases, the driver's care is reduced. Driving mode becomes more irrational. In addition, the risk of diseases by such professional diseases as cervical, lumbar osteochondrosis, ORZ is increasing.

On various types of passenger cars, heavy trucks, special machines are installed in the engine preheater. Equipping this device, facilitates the launch of the internal combustion engine, increases the resource of the power unit, and also improves comfort when using the winter machine.

On the model of cars that are not equipped with a regular engine heating system, it is possible to install this device. However, when installing, you need to correctly pick up the appropriate heater for the motor, and correctly install.

Why do you need an preheater?

Cold launch of the power unit reduces its resource at 400-500 kilometers. In addition, not every attempt to start auto in the winter, ends successfully. It is most difficult to launch the engine in the northern latitudes of Russia, there are drivers of heavy vehicles, do not devour the motor overnight, thereby do not give it to cool. This affects fuel consumption, and the resource of the power unit.

Previously, soldering lamps used to warm the motor. The lack of such a method was that the flame could damage the car, in addition, certain knowledge and skills were needed to work with this device.

To solve the problems of winter launch, you need to purchase an preheater - a device that warms the motor and the interior before starting the car. It significantly increases the service life of the power unit, increases the comfort of travel in a heated cabin and reduces fuel consumption.

Types of automotive preheaters

Preparation automotive heaters depending on the type of power, and the application area are divided into:

• Electric.
• Autonomous.

In turn, autonomous heaters are divided into:

• Air.
• Liquid.

The engine preheating systems are divided into the type of fuel used by the car used. For gasoline and diesel engines use different types of heaters.

Installation takes into account the type of vehicle, and the type of heater. If the device is selected incorrectly, heating the motor before launch, will be ineffective or lead to the booster of the brake fluid.

220 volt electric heaters

The electrical heater has a simple device. Cooling fluid is exposed - subsequently, it is flowing across the cooling system tubes, the machine engine warms. Most often, the electrical heater has a cord connected to a 220 volt socket and a heating element.

Device, depending on the configuration, is equipped with a device, to recharge the battery of the machine, a timer with a thermostat, a fan, a remote control.

The installation of such a device is quite simple, and does not require a visit to a specialized service center. To perform it, you will need to implement the following procedure:

1. Dry not less than 2 liters of antifreeze.
2. Disable the nozzle from the stove.
3. Hover the heater. To do this, use a complete heater bracket.
4. Connect the automotive heater to the stove using hoses.
5. Attach the nozzles to the stove, to build the entire system.
6. Pour Tosol either antifreeze.

As for the nuances of use, then, in most cases, for a complete warming up of the motor, you need not more than 30 minutes. However, with overly low temperatures, time will increase to 1-2 hours. The warm-up device that is connected to the car oven, warms the motor connected to the system to it, and the vehicle salon. The heater must be used only if the air temperature does not exceed -5 degrees. In other cases, the use of a vehicle heating system is not needed.

It is impossible to exceed the heating time of the motor, it can lead to boiling coolant. In addition, due to overheating, fire may occur.

The average cost of the electrical heater varies in the range from 1000-5000 rubles, depending on the brand, the producer and functional country.

In the Scandinavian countries, there are columns equipped with 220V sockets installed on the parking lots, which allows you to put the car for heating at any time.

Autonomous engine preheating system

Autonomous heaters are much more convenient electrical, as they can function without connecting to the network 220 volts. However, such devices are more expensive, and complex in the installation. The device is a small chamber, inside which the capal pin is placed, and the fuel-air mixture. Chamber walls have a constantly circulating cooling fluid that warms up, heats the motor, the interior and promotes the thawing of glasses.

The heater of the autonomous type is mounted or in the cooling system of the car, or in the electrical power system. Equally applicable both on gasoline and diesel engines.

Autonomous heaters are divided into:

• Liquid.
• Air.

Liquid autonomous heating devices are intended for SUVs, minivans and compact cars. The device of the preheating, intended for small cars, is installed on machines whose engine volume does not exceed 2.0 liters. Differs high economy. Heaters that are intended to use on SUVs and minivans have a large size and efficiency. However, they consume a much larger amount of fuel. You can also find universal heating systems, which can be used both on large cars and small machines with the same success.

Air have much larger dimensions, compared with liquid, but also allocate more heat. They are used on ships, airplanes, special techniques and large trucks.

Heat batteries

Thermal accumulators belong to the liquid type of automotive heater. The essence of the work is that through such a battery there are tubes of the car cooling system. During the engine operation, the heat is superfluous in the battery and saved there up to 48 hours. When the cooled engine is started, the pump and when pumping antifreeze or antiflower, the heat is transferred to the cooling system.

The main advantage of such a device is the high heating efficiency, and long maintaining heat. The disadvantages include the complexity of the installation, and the need to replace the components. Over time, valves, tubes and control levers wear. Also a minus operation is its cost. On average, the car enthusiast of the thermal battery will cost 7-8 thousand rubles.

When buying a thermal battery, the models produced in China or Russia should not be purchased. It is best to pay attention to devices created in Scandinavian countries. Such heaters can boast high quality, good heat conservation and efficiency.

Heaters diesel fuel

Under the influence of low temperatures, diesel fuel loses its fluidity. The wasolar becomes muddy, crystallizes and paraffinization occurs. As a result, the fuel becomes dense, which makes it difficult to pump through the filters, or completely makes it impossible.

One of the devices that allows to protect diesel fuel from freezing is the preheater. Thanks to its use, the fuel in the tank and the filter separator is heated. For these purposes, preheaters of the following types are used:

• Heated tankers, and heaters in the tank.

One of the most common options. After the warming is completed, the dieselgery falls into the fuel line. The heat is maintained due to the arrival of heated diesel fuel from the "return".

• Bandage heaters (have a flexible tape form).

Heat the fine cleaning filter, the control button is displayed in the car interior. After reaching the operating temperature, the heater turns off automatically.

Popular model of preheater

Among the models of preheater, the following devices are particularly popular:

The device produced in Germany. Refers to compact heaters, economically in electricity consumption. Works from the car battery. In the cold season, the motor quickly and effectively warms. In the summer, a vehicle salon can air.

• Teplostar 04ts.

Domestic heater produced in Samara. It works from the outlet 220V, simple and efficient in operation and maintenance. Many motorists will delight the relatively low cost of this device. A special chip can be called a remote control device. Also, in the event of a failure, the functioning of the preheater is terminated.

Norwegian non-autonomic heater. In addition to the main function - the engine warming, can recharge the battery (this option is useful, since in the cold the battery significantly loses its power). The buyer has the opportunity to purchase basic and advanced sets, and combine them at their own discretion.

When buying an preheater, you should not save. Diesel heaters or heat accumulators, with poor quality assembly, can quickly fail, and technical fluids get into the operating room of the car. This will lead to smoke or fire.

In summing up, it is worth saying that the use of the heater significantly accelerates the process of starting the car, saves fuel, and also makes the journey in the car more comfortable, due to air heating in the vehicle cabin.

Below is a video about automotive preheaters

When coldly occurs (usually for any of us, "sudden") every car owner thinks whether his car will be charged or not. And even if the battery coped with a difficult task and the "cold start" was safely implemented, with such a method of exploitation arises a number of negative consequences:

• engine details are faster wear out;
• the load on the battery increases: as a result, the service life is significantly reduced;
• the engine works quite a long time at idle (and, it's not the most "useful" mode for it).

The engine heating will not only extend the "life" of the motor without repair, but also to largely increase the comfort of the use of the car in winter.

Principle of operation and varieties of preheating engine

All systems, regardless of the design, installed in cars to facilitate the start of the motor in the cold season, are heated not to the engine itself, and increase the temperature of its ambient coolant (abbreviated it is called PP). Therefore, the toosol, saving engine from overheating while driving, is heated with the preservation device, heats the engine elements, which contributes to the implementation of its easy launch (even at very low temperatures).

According to the principle of operation, all the preheaters of engines (both gasoline and diesel) are divided into two main groups:

• autonomous;
• electric.

The first as a source of energy use car fuel. To operate the second, it is necessary to connect to 220 volts to the power supply.

Autonomous preheating heaters

This type of engine preheaters is most functional, as it does not depend on the connection to external energy sources (therefore, they are called autonomous). However, their cost is higher than electric. Install such a heated engine with their own hands, not possessing the necessary technical skills and sufficient experience, is quite difficult. In addition, the independent installation of such high-tech devices leads to a loss of a warranty on the car.

On a note! If you install a heater in an authorized center, then all warranty obligations are preserved.

And despite the fairly high cost, such devices are widely popular. By analogy with autonomous systems of building heating, such devices are sometimes called boilers. Until recently, the most famous manufacturers of these products were German "Webasto" and "Eberspacher (Hydronic). But now, Russian firms are worthy of a worthy competition: "Binar" and "Teplostar"; as well as the Chinese "Belief".

Autonomous heating consists of:

• fuel pump;
• the rigid candle or the incandescent pin (from tungsten or cobalt);
• evaporative burner;
• combustion chambers;
• heat exchanger;
• supercharger motor;
• input and cooling fluid outputs;
• control unit.

The boiler is installed in the engine compartment and embed into the fuel and cooling system of the car. The scheme presented below helps to understand how the autonomous heater works.

When the device is turned on (with a button, signal from the timer, the remote control unit, or the GSM module), the air-fuel mixture enters the combustion chamber and is set on its plane candles (or incandescent pins). When combustion, the heat exchanger is heated, which leads to the heating of the coolant. Pump pumps toosol through the engine and radiator of the standard interior heating system. When the fluid temperature is reached, about 60 ° C automation unit turns on the cabin fan.

The "Webasto Thermo Top Evo Start" heater (5 kW), designed to install on cars with an engine capacity of up to 5 liters, with a programmable weekly timer and installation items costs about 25,000 rubles. The remote control unit (range of about 1 km) and the GSM unit (for the possibility of managing a mobile phone) are purchased separately. The installation of the certified dealer will cost no more than 8000 ÷ 10,000 rubles.

Passive electrical heaters

In Canada and all Scandinavian countries, outlets where you can connect such heater, equipped, practically all parking spaces.

We still have such a service only a few paid car parkings. And, so if you live in a private house or keep the car in the garage, then, undoubtedly, this device will greatly facilitate your life in the cold time.

The easiest technical plan and the most economically available way to perform a pre-heating of a diesel or gasoline engine before starting the winter - installing an electric heater to place one of the engine cylinder block plugs. Technologically, it is a conventional boiler for certain sizes and power. The circulation of the fluid is carried out by gravity (the fitting rises upstairs, and the cold drops down). The product selection depends on the specific engine model. The market is widely represented by devices, practically, for all car brands from a wide variety of manufacturers.

For example, the electric preheating of the engine from "DEFA" for the VAZ-oskov "dozen" with a capacity of 550 W with additional spacers (for better fixation from the inside of the cylinder block) and a sealing sealing ring costs 1,700 ÷ 1800 rubles. And for the "Subaru Forester" a similar device (with a threaded fastening) with a capacity of 600 W on the same manufacturer will cost already at 2600 ÷ 2800 rubles.

Depending on the type of plugs, manufacturers produce such devices for both the threaded installation and pressing. The model is chosen depending on the variety of engine itself.

Possessing even minimal technical skills, install such a device for engine heating from 220 in your own hands (with cable and connections for connection) is quite simple:

• partially merge the cooling fluid (usually enough 2 ÷ 2.5 liters);
• we dismantle the plug on the cylinder block (the most closely located to the central part of the engine to ensure better warming up);
• insert the heating element instead;
• we connect the electrical cable;

• a socket for connecting the power grid either to outward through the radiator grille (for those who are not very worried about the appearance of the car), or fastened in a convenient location on the front bumper (or under it).

To make it convenient to use a similar device, you can additionally set the on / off timer.

Electric heaters with coolant circulation

Electric heaters with pumps (to ensure the circulation of heated fluid through the engine and the cabin stove radiator) allow you to evenly warm the entire engine. Although such devices are more expensive than passive electrical systems, the effectiveness of their work is much higher. The thermostat built into the case automatically turns off the heating when the fluid temperature is reached 80 ° C.

Installation of such a device is quite simple:

• merge the cooling fluid;
• krepim device body;
• we carry out the insertion into the standard cooling system (between the output from the cylinder block and the inlet nozzle of the cabin radiator);
• fill the coolant.

The Russian engine heater from 220 V "NEXT satellite" (with a capacity of 1.5 to 3 kW, which is chosen depending on the climatic operating conditions and volume of the engine) with pump and automatic power outage costs from 2200 to 3200 rubles.

Supplementing such a device relay with a thermal sensor to turn on the stove fan, we can count on not only the easy engine start, but also breathed to a comfortable temperature of the car.

Flexible thermoplasties

The above-considered devices embedded in the cooling system do not provide heated oil in engines. This is their significant disadvantage. With severe frosts, even a good warm engine, the thickened oil is quite problematic. Flexible wrapping plates for the preheating of the engine make it possible to make a self-made device without much difficulty (in just 20 ÷ 30 minutes) an increase in oil temperature. Technologically, they are a heating element pressed between two layers of silicone. On the one hand, the plates are adhesive composition (3m), with another porous material with good thermal insulation. The power of one heating element ranges from 60 to 400 W. Such devices are released to connect to the on-board network of a car with a voltage of 12 or 24 V, or to household electrical power grid by 220 V. The cost of these products from "Hotstart" or "Keenovo" depending on the size and power is 2000 ÷ 8000 rubles per piece.

Using such devices, you can easily warm up the engine crankcase or automatic transmission. One plate with a size of 127 x 152 mm and a power of 100 W is enough for a car with a motor with a volume of up to 3 liters.

Installation of such products is quite simple:

• clean the place of installation from dirt and paint;
• then remove the protective film and do not forget to glue the plate;
• at the edges we apply a layer of sealant;
• we fix the electrical wires and drag them to the location of the connection.

By installing such plates (with a built-in thermal sensor) to the car tank and fuel filter, you can create a device for heating the diesel engine fuel system.

The main advantages of such devices are:

• Low power consumption.
• Ability to use for heating a variety of components and car mechanisms.
• Easy installation (regular systems of the car remain unaffected).
• Autonomy (when using plates with 12 V nutrition).

In custody

What a heater is better to install on the car depends on your personal preferences, financial capabilities and parking sites. By installing the heating system from the proven and well-proven manufacturer, you will not only save time, but you will be sure that your car will start with serious frosts.

In the northern regions, the problem of launching a motor in the cold is relevant - frost thickens oil, complicating crankshaft turning and worsens the evaporation of the fuel, reduces the accumulator tocottation. Even the difference in the thermal expansion of individual details plays a role: the piston with a floating floor of the finger on the cold snacks it, and the bottom head of the steel connecting rod is shrinking stronger than the cast-iron crankshaft.

Therefore, heading the engine, it is necessary to warm it up in order not to risk the breakdown at the beginning of the movement. It reveals minus already diesel engines: at idle they are slowly heated even in the summer, warm the diesel engine on the winter is impossible. Progazovka in the cold - a considerable risk of grinding of the crankshaft liners, laying beds of camshafts.

The practice of preheating the engine is as old as the cars themselves - and now you can see how the motor is heated by a soldering lamp. But this method is inconvenient and unsafe. So the homemade, and the factory systems of the engine preheater appeared long ago and continue to maintain relevance.

Operating principle

The idea of \u200b\u200bthe engine preheater is simple: since the motor is filled with antifreeze, then heating antifreeze from an extraneous source, it will be possible to evenly warm and engine itself. Working gaps between the details will return to normal, oil will warm up (it will warm up in the pallet from the heat of the crankcase and on many machines after the launch will start passing through an inlet-oil heat exchanger) and an intake manifold. For diesel engines and motors with a distributed injection, it is less relevant, carburetor motor heating the collector and the carburetor itself in the area of \u200b\u200bthe ocher joclars is needed. Part of the heat motor will give and the gearbox, which is also important. Sitting into the car, you can immediately defrost the glass.

Preheater are divided into two categories

1. Electric.
2. Autonomous.

The simplest preheating electrical heaters are the beans in metal nozzles embedded in the lower nozzle of the radiator. Such designs are self-made due to simplicity, in the northern regions of Russia you can see cars with a fork 220V sticking out from under the hood. In Northern Europe, you can even find parking, where each parking lot has a column with a socket.

It is clear and minus this - heating is slow due to the lack of forced fluid movement in the circuit. It is avoided by entering an additional electric pump in the cooling circuit, but the need to connect the preheater each time to an external current source remains. But the electrical heaters are not losing popularity, there are interesting models that heat the engine and simultaneously recharge the battery.

The liquid (autonomous) heater is connected to the electrical system, the fuel line and the cooling system.

But how to heat the motor, when there are no sockets near? Option is only one - burn your own fuel. So the autonomous preheating heaters are arranged: these are small stoves, burning fuel, taken from the tank, and warm the built-in heat exchanger. Such an preheater is easy to automate - connect a timer to it, output control from alarm. Thanks to this, on commercial vehicles, such models that can even be asked for a weekly heating schedule, put from the factory, and the name of the manufacturer of autonomous heaters Webasto repeated the fate of the "Xerox", becoming in a conversational language by synonymous with preheating systems.

Of course, there are offline heaters from its cons:

1. First, they need fuel - with an almost empty tank you will stay with a cold car.
2. In the same way, the battery is also needed - the motor will warm up with the old battery, but the starter will not scroll through it.

Therefore, many heating systems integrated with onboard electronics, with a decrease in fuel level or battery charge, are automatically blocked below the critical.

This fantasy is not limited, but its other fruits are considered more curious. For example, thermal batteries are invented - these are thermoses in which some coolant volume is stored. While the motor works, the thermal battery is included in the overall circuit and heated to the operating temperature, when the motor is silent, it turns off, keeping heat in itself. Cold motor, the driver again receives a dose of preserved heat antifreeze. Seriously refer to such developments is difficult due to the small "storage period" of the heat of heat and due to the dimensions. But they manage to sell - this is the Canadian CENTAUR systems, and the Russian Avtotherm.

If you remember uniquely useless devices, these are heaters of oils inserted through the dipstick. Not to mention the low efficiency of the heating of oil in the pallet and the power of such "heaters" is so worn that they cannot heat the oil, it is useless to plant the battery.

Installation

Binar-5 installation scheme

The simplest electrical heaters are installed simply - we drain the antifreeze, cut the section of the lower nozzle of the radiator at the desired length, insert the heater to the cut pipe, tighten the clamps and re-fill the antifreeze. It remains to stretch the wires so that the car is easy to "connect to the outlet."

Why is the electrical heater cras into the lower nozzle? It accelerates heating due to thermal convection - heating systems also work without forced circulation. When the antifreeze is heated in the upper nozzle in the radiator, and not in the motor - the closed thermostat will not give the fluid to come through convection in the block.

Video: Production of heater of diesel fuel type "Outdoor Snake" with your own hands

If you do not have a cheap Russian tan, and a more advanced device, it is crashed into the nozzle going to the stove. Such devices are a monoblock that combines the preload heater with a pump of low power, so in the main mainstream of cooling, having a large passage section, cannot be turned on. But the heating of the motor with them is faster, and at the same time the salon stove simultaneously heats.

For a number of motors, the electrical heaters are released with the calculation of the installation instead of the technological plugs of the motor - for their installation you will need already plumbing skills, as you will have to first remove the desired plug from the motor, and then tightly set the heater to the opening of the block. It is better to entrust to professionals, as well as the installation of an autonomous heater - it will take intervention and the engine fuel system, and the competent placement of the heater exhaust.

The best models of electrical preheaters

DEFA

The Norwegian firm is a leading manufacturer of heaters of this type. Releases electrical heaters, which are crashed into the unit, and are installed in the cooling circuit. The main advantage of DEFA systems is modularity: the heater is complemented by the battery charger, the autonomous fan for the cabin, the inclusion timer. If you wish, the model of the heater with a thermostat is chosen - such a heater is left permanently on, without risking the engine and saving electricity, since when the preceded temperature is reached, the heater will automatically turn off.

Calix.

Another Scandinavian company. In its model range, universal heaters embedded in nozzles, they are simple, reliable and effective. Also used modular design: the buyer can self configure the desired systems, to the appropriate heater, paying additional control devices, charging for batteries. The owners of diesel cars will appreciate the presence of Calix in the model range convenient in the installation of tank electrical heaters.

Severs

And this is already products of CJSC "Leader". With all the advantages of European heaters, the price remains a disadvantage, so that the proposals of the Russian manufacturer will not be superfluous.
