Varieties of engine preheaters
According to the principle of operation of PPD for gasoline and diesel engines are divided into two main groups:
- autonomous;
- electrical.
Autonomous
They use the fuel of the car itself as energy. They are more convenient, do not depend on external sources, but they are more expensive. If there is no standard heater, a ready-made installation kit is installed at the service station.
Electrical
To operate this option, you must be connected to a 220 volt power grid. The principle of operation is the same as that of a conventional boiler, in which the coolant is heated. The circulation is carried out by gravity (the heated one goes up, and the cold one goes down).
Autonomous liquid heaters are installed under the hood of the car and operate on one of the types of fuel: gasoline, diesel fuel, gas.
Longfei with pump 3 kW
Heats up the coolant and makes it move in a small cycle, warming up the power unit even without it idle work without wasting fuel. Heating element is used for heating, circulation - centrifugal pumping equipment. These elements are located in the body of the device and operate from a household power supply with a voltage of 220 volts.
Longfei 3 kW
This model has a thermostat and a power control system. When the coolant reaches the upper temperature limit, the equipment shuts down. As soon as it cools down to the lower set limit, the heating and the pump are automatically turned on. As a result, the engine is always ready to start and start moving.
Longfei miniature heaters are designed with the market in mind. Their dimensions are only 8 × 7.7 × 11.8 cm. Heaters are securely fixed to the branch pipes with clamps, without requiring special fastening for this. They are fixed in a sequential method by cutting into the inlet tube of the cabin heater. The model warms up the engine evenly at high speed. The electronics are highly resistant to moisture and are reliable.

Prestart heaters for passenger cars are presented in a large assortment, we will consider the most popular models of 2018. Heater Webasto t400vl is designed specifically for Russian market... A distinctive feature is the ability to warm up not only the car engine, but also create a comfortable temperature in the cabin.
WEBASTO Thermo Top Evo Comfort + The power of the Webasto unit is 5 kW, which is enough for normal operation at gasoline engines with a working volume of up to 4 liters. The delivery set does not provide for a standard control body. Higher coolant temperature, early start-up of the ADP5 fan, faster heating thanks to the control of the liquid pump and better heat transfer "work" for maximum efficiency. Severs is a budgetary volatile heater that operates on a standard electrical network. The set includes a thermostat that protects against engine overheating. Heating up to 60 ° C is carried out in 1-1.5 hours. At a temperature of 85 ° C, the system stops working. If the coolant temperature drops to 50 ° C, the heater starts up again. It is noteworthy that the heater is protected against moisture and electric shock.
The only drawback of Severs is that he needs an outlet, so such a device can only be used if there is an electrical outlet. DEFA WarmUp 1350 wFutura - maximum preheating system for the engine, passenger compartment and charging battery car. The system is controlled via the Futura mini-timer.
The kit includes:
The big advantage is that the device consists of module blocks and armored connecting cables. Optionally, they can be installed either as separate units or as a whole complex. How to warm up the engine when the outlet is not nearby? Option one - burn your own fuel. This is how autonomous pre-heaters are arranged: these are small stoves that burn fuel taken from the tank and heat the built-in heat exchanger. It is easy to automate such a pre-heater - connect a timer, alarm control output to it. Teplostar prestarting BINAR-5S (gasoline)The pre-heater of the BINAR-5S engine is a domestic analogue of the well-known German Webasto, which favorably differs from it in terms of price and with a wider operating temperature range - up to -45 ° С. It is installed on passenger cars with a liquid cooling system running on gasoline.
Control of the BINAR-5S operation is carried out through an alarm, a remote control, or through an application via a GSM modem. This makes it possible, on command or on a schedule, to heat the antifreeze in the car to a temperature of 85 ° C with subsequent shutdown or reheating at low power. A set of equipment designed to be connected to a cabin heater or as a separate unit for easier starting a car in winter.
Installed on all types of equipment, including commercial vehicles and trucks. The kit includes:
Users in the reviews draw attention to the fact that Thermo Top Evo Comfort, although it is intended only for heating the engine without a passenger compartment (for this there is a more expensive version of Top Evo Comfort +), the wires for the interior heater function are also included in the braid of wires.
The petrol version has a maximum heating output of 5 kW at the start of the engine warm-up cycle. During operation, the power of the engine heater is reduced to 1.5 kW, which leads to a decrease in fuel consumption and battery charge. Diesel at subzero temperatures becomes thick, like jelly, as a result of which it becomes daunting to start the engine even at -10 ° C. Someone chooses a diesel of special winter brands, but it is not sold at all gas stations. Others opt for a diesel preheater. One does not interfere with the other, but in the aggregate will create generally ideal conditions for any frost. TEPLOSTAR 14TS-10, 20TS, 15TSG are new models with a capacity of 12-20 kW, designed for buses and trucks that run on diesel or compressed natural gas. It is installed even on Kamaz.
Teplostar Diesel engine-heater 14ТС-10-12-С Such heaters provide warming up of the car engine vehicle and interior during the cold season. The main advantages of vehicles (diesel), on which the installed heater "TEPLOSTAR":

The engine preheater is a special device that allows you to warm up the power unit of a vehicle without starting it. After all, they very often arise in winter. Almost every car enthusiast had a situation when he came to the parking lot for his car, but he would not start. The reason for this is the low ambient temperature. In such a situation, such a heater will come to your aid.
Its functions:
- preheating power unit;
- facilitating the procedure for starting the engine in the cold season;
- heating the air space c.
This device keeps the engine at a constant temperature even when the machine is not running. In some modifications, the function of heating the interior of the vehicle is built-in.
Having such a device in your car, you can easily start your car in the winter season. And also, you will not be afraid of the cold in the car, because you will quickly heat the air to the state you need.
Types of devices and their characteristics
There are currently four types of heaters. Let's consider them in more detail:
- Liquid heater... Now, this device is the best of all offered on the market. With the help of it, you not only start your power unit without any problems, but also heat the interior of your vehicle. This heater is installed underneath and connected to the hot water heating circuit. The liquid device has the ability to connect a timer that will start working at a specified time. It has the ability to start through a radio signal or by means of a remote control remote control... This device works almost silently and is very economical.
- Autonomous air heater... It is designed to heat huge volumes. Therefore, it is very often used in vans and buses. This device works quietly, heats the air quickly, and also consumes a small amount of fuel.
- Electric heater engine (on-line heater). The principle of operation of this mechanism is that an appropriate heating device is installed in the cylinder block, operating from a 220 V electrical network.This device is suitable for those motorists who store their vehicles in garages, that is, where there is an electrical outlet. After all, it only works on electricity. If you leave your car in a parking lot, then an electric heater simply won't work for you. Look for alternatives.
- Heat accumulator... This device works on the principle of accumulating hot cooling inside itself. He is able to keep the set temperature for an average of two days. During engine start-up, hot antifreeze passes through the cooling circle several times, thus heating the power unit in a short period of time.
Almost all prestarting mechanisms have similar operating principles. Such devices have combustion chambers made of stainless metal, where fuel enters with the help of a nozzle, and air through a fan. This is where the mixture is ignited. It is done from a glow plug or from a candle. Antifreeze heating occurs due to an increase in temperature during the combustion of the air-fuel mixture. A pump installed in the cooling system pumps liquid, and this heats the entire system. Then, the stove fan is connected, with the help of which the interior of the vehicle is heated.

Summarize
The pre-heater is an indispensable item in the winter season. Indeed, when, it is very difficult to start the power unit of the car. Then this device will come to the rescue. With the help of it, you not only start the engine, but also be able to heat the air inside the car. On automotive market there are currently four types of heaters available for sale. The car enthusiast must choose for himself exactly the one that suits him in all operational characteristics and price.
The heating system for 220V engines is a device that allows heating fuel line or other elements of the power unit before starting. The use of third-party resources allows prestarting electric heating to provide savings in diesel or gasoline fuel during a cold start in the winter season.
Modern 220V engine heating systems include:
- heating element with a capacity of 500-5000 W;
- timer control unit;
- battery recharging unit;
- fan heater (for heating the passenger compartment).
Good to know
Some electric heaters are equipped with pumps that generate pressure in a small circuit of the cooling system, which allows for faster and more uniform heat transfer.
Principle of operation and possibilities
The principle of operation of car electric heaters is to preheat antifreeze to an operating temperature (60-70 degrees). As a result of heating consumable moves along the lines of the cooling system upward, simultaneously warming up the elements of the motor.
It's important to know
To provide high pressure due to the temperature difference of the heating system without a pump, its connection to the cooling system must be made to the lowest point of the cooling circuit.
Learn more about how the electric heating of an internal combustion engine with pump works:
- The mains cable of the heating system is connected to a household socket.
- When energy is applied to the heating element, it is activated and starts the pump.
- The refrigerant circulating through the lines of the system receives heat energy and heats up.
- When the temperature rises to the required level, the heating element is turned off using a relay. If the operating parameter drops again, the relay will activate the antifreeze heating system.
Additional features of heating systems, depending on the model and type of device:
- recharging batteries;
- warming up the passenger compartment, thanks to the injection of a warm air stream into the car;
- remote control by timer or commands coming from the remote control, as well as from a mobile device.
Key characteristics of the electric heater
The main characteristics of the heating system:
- Power, measured in kW. The higher this indicator, the faster the warm-up will be. working fluid in winter. For example, systems with a power of 1.5 kW allow the refrigerant to warm up in about 3.5 minutes. If this parameter is increased to 2 kW, then the heating time will decrease to 3 minutes.
- Frequency, measured in hertz (Hz). This indicator determines the temperature value of the activation of the thermostat.
- The value of the circulated flow, measured in l / s. This parameter depends on the diameters of the inlet and outlet holes. In most modern heating systems, the lines are 1.2 cm in diameter.
- Equipment dimensions. Depending on the manufacturer and type of device, these indicators differ. On average, the length of the device is 15 cm, and the height and width are about 9 cm.
It's important to know
Each heating system has its own degree of protection, the most common brands and models are marked "IP 34". This indicates that the equipment is safe to use, and the possibility of a short circuit is completely excluded.
What affects power
Indicators that affect this characteristic:
- Limiting frequency of equipment. This indicator is usually 50 Hz, but there may be deviations up or down.
- The diametral dimension of the line, which determines the circulation rate of the heated consumable material.
- Location and correct installation. The device should be installed as firmly as possible and not be blown out.

How to install an electric heater
Installation of electrical heating systems from PR, Longfei or devices from other manufacturers consists of the following steps:
- Instrument preparation.
- The choice of connection scheme - serial or parallel.
- Installation and verification of the performed actions.
Safety rules that must be taken into account when installing a 220 volt engine heater:
- The unit must be connected to a three-wire single-phase network designed for 220V. It must have an earthing contact through a circuit breaker with a protection current of 10 or 16 Amperes for 1.5-2 kW and 3 kW, respectively.
- A residual current device must be installed with the circuit breaker. This unit is designed to protect a person from the effects of current in direct or indirect contact with a damaged cable. Also, a protective device will prevent burns when touching an uninsulated part of electrical equipment.
- Activation of the electric heater after installation on a car with a running engine is not allowed. Also, you cannot turn it on if there is no antifreeze in the cooling system.
What do you need?
More details about what you need to prepare for the installation of a 220V engine heating:
- a set of screwdrivers of different lengths - with Phillips and flat tips;
- set of wrenches;
- rags;
- container for draining the spent liquid;
- stationery knife;
- additional branch pipes or adapters, if a complete set of the heating device is required.
Table: electrical heater installation diagrams
| Scheme | Description |
Parallel installation  | This method involves mounting the part opposite the stove radiator device. The heating device is connected to the motor and thermostat or with these elements, as well as the heater of the stove. |
| Sequential installation
| The heating device cuts between the power unit and the radiator of the interior heating system. This option is more preferable for cars with a parallel arrangement of terminals, since the equipment is installed in one pipeline through which the refrigerant enters the heater. It is important that antifreeze always has access to the stove. |
Algorithm for sequential installation
Algorithm of actions when performing installation:
- At the first stage, it is necessary to find the pipe leading from the power unit to the interior heater. To do this, you need to start the engine, as a result of which the line will warm up well and quickly. The pipe itself can be felt by hand.
- Then it is necessary to drain the coolant from the engine (about two liters should come out).
- It is necessary to find a point to fix the heating equipment on the vehicle body or its motor. Mounting can be done with a bracket.
- With the help of a clerical knife, the required line is cut and the part is installed. The part coming from the power unit is fixed on the water intake, and the section used for the radiator device of the stove is fixed to the water outlet.
- On next step all connections are fixed with clamps. It is also necessary to secure the heating equipment, but it is necessary to act as carefully as possible to prevent possible leakage of liquid.
- Then through expansion tank refrigerant is being added. At this point, make sure there is no leakage.
- Route the wire from the heating equipment along the body so that the plug protrudes outward. The wire should be secured so that it does not dangle.
Parallel installation step-by-step
When installing the heating system in parallel, the procedure is as follows:
- The refrigerant is being removed from the system.
- There is a drain device on the cylinder block of the power unit; it must be dismantled. Instead, a fitting is installed.
- A clerical knife is used to cut the branch pipe connecting the engine of the power unit and the radiator device of the heater. A tee adapter is being installed.
- The location where the heating device will be installed is selected.
- Using previously prepared lines, the water inlet is fixed with a fitting, and the weir must be connected to a tee.
- The next step is to attach the pipes and hoses using clamps.
- The heating equipment is additionally fixed in place.
- The expansion tank is filled with refrigerant (it is recommended to use drained coolant).
- The 220-volt cable is secured in place using retaining straps so that it does not come into contact with moving motor components. It should also be placed away from heated parts and surfaces adjacent to the engine.
- It is advisable during installation to bring the socket or plug of the heating device to the front grille of the car. This element must be closed with a plug, which will prevent moisture and dirt from getting inside. A cable with a suitable ferrule must be purchased in advance.
- The power unit starts up, after which it must be allowed to run for a few minutes. During its operation, it is necessary to check the quality of the connection of all elements and pipes for leaks. If the antifreeze has dropped and the level is below normal, it must be replenished.
- Then the heating equipment is activated. At this stage, you need to make sure if there is a noise of moving antifreeze. The outlet arm of the system should warm up in about 2-3 minutes.
Consequences of incorrect installation
Consequences that may appear as a result of improper installation:
- The installed system will warm up the interior very slowly or will not be able to heat it at all. If the boiler is embedded in a large cooling circle, then it will heat all the coolant, respectively, the thermostat will be useless.
- At the final stage of installation, it is necessary to properly fix the electrical network cable. If this is not done, it can quickly wear out and rub off, which will lead to a disruption in the signal supply to the heating equipment. In addition, a short circuit may occur when the device is connected.
Video: installing the engine heating system
on the channel "Do-it-yourself car service" a video was published, which describes in detail the procedure for self-installation of the Longfei heating pump device on a car.
The most inexpensive type of engine preheater is electric, built into the cylinder block, or located next to it. In fact, this is a modified electric boiler. Only its main task is not to bring the liquid to a boil, but to heat it up to such a state that the engine can start quickly in the cold season.
With the first view, everything is clear: the power of the devices is only 400-750 W. Their purpose is to maintain a certain temperature regime directly in the cylinder block. In addition to a heating element and a wire leading to a 220-volt outlet, there are no additional sensors, nozzles and other devices here.
Video - self-installation of an electric engine pre-heater for 220 volts:
A "boiler" with a wire is not enough for you? Then it will not be superfluous to buy an ordinary timer, if accuracy up to every second is so fundamentally important to you.
The most famous Russian heaters of this type are "Homeless" (from 1,200 rubles), "Start-mini" (from 950 rubles). The mentioned devices are mainly intended for, but are there any obstacles for domestic craftsmen?
For the sake of fairness, it should be noted that our motorists still consider the car primarily a luxury, on which too much money has been spent. People are somehow not ready to "pamper" their iron horses expensive heaters, and therefore the popularity of models, the cost of which does not exceed 2,000 rubles, is growing. The same cohort includes models with the names "Lestar", "Start M1", "Start M2", "Siberia-M", "Alliance".
Recently, units of this type have begun to improve, they are supplied not only with timers, but also with an emergency switch, which, in case of overheating, stops the supply of electricity. The disadvantage of such structures is that it has become more difficult to install them in the space near the engine.
Another point that makes the use of such devices not too pleasant is the need to open the hood lid each time in order to stretch the wire from the device to the outlet. True, now the connector has already begun to be displayed under the bumper, which greatly facilitated operation.

More "advanced" pre-heaters are autonomous, adapted to power supply from the car's mains and designed for a voltage of 12 volts. Along with a lot of advantages, such devices also have very significant disadvantages:
- the presence of internal fixtures that are subject to wear and tear and require replacement;
- the formation of deposits in the pipes and combustion chambers due to insufficient cleaning of the fuel;
- installation requiring certain skills;
- great value.
This is just the last point - the main reason why the purchase of pre-starting autonomous heaters is constantly postponed until later. After all, not everyone can easily shell out an average of 30,000 to 90,000 rubles per device, even if its usefulness is beyond doubt.
Those who installed on their car leave the most different, but among them there are quite a few positive ones.
