Installation of an additional heating device in a VAZ-2114 car

Why is additional heating needed?

When storing a car in open parking lots, the metal body of the car quickly cools down. The inside of the glass is covered with a thin layer of condensation, which later turns into an ice crust. Within a few hours of parking, almost all parts, including all rows of seats, reach ambient temperature.

Heating adjustment from the passenger compartment

In the morning, the driver tries to quickly bring a cold car to normal temperature, but for such a stressful state of the car, one stove will not be enough . Even if you start driving in a poorly warmed car, you can wait more than one hour for it to reach normal temperature conditions.

If, from the very beginning, all the heat is taken from a cold car to heat the interior, then there will not be enough heat for the engine to return to normal temperature conditions, which means that the power plant will have less and less heat for the interior and will not be able to do without an additional heater.

A frozen driver is ineffective at driving. He is stressed and may lose attention and control of the road. This can lead to emergency situations.

Electric heater

This method is the easiest to implement. To do this, you only need to buy a ready-made device, which you can get in almost every car store. This heater is installed on a dashboard. It is usually connected to the cigarette lighter. Experienced auto electricians advise running the wires directly to the battery. The fact is that the power supply requires a fairly high current strength, which can negatively affect the standard wiring

. When connecting directly, do not forget to put a fuse on the wire, heat is of course good, but safety is more important.

The advantages of such equipment include ease of installation. There is no need to interfere with the standard systems of the machine.

Even when connected to the battery, the process occurs in parallel with the wiring. The main disadvantage is the high energy consumption. This will result in the need to periodically recharge the battery. Therefore, car enthusiasts use such heaters only for a short time, for example, when starting the engine, in order to warm up the windows faster.

Additional radiator

Very often, motorists solve the problem of heating the vehicle interior with the help of another radiator and fan. It is connected to the standard heater, for which additional pipes are installed in the passenger compartment. This solution is quite common for the interiors of passenger minibuses, buses and vans, which have a large volume.

Autonomous heaters for minibuses

The advantages include:

• standard operating principle;
• efficient and fast heating;
• the ability to select a profitable option in any auto store;
• lower cost than analogues.

The disadvantages of this option are:

• the need for proper installation;
• heating efficiency depends on the degree of engine warm-up;
• additional consumables are required - hoses, tubes, insulating materials;
• interference with the appearance of the interior;
• there are no guarantees that the desired effect from the installation will be achieved;
• the volume of coolant increases.

How to install an additional stove

To install an additional heater in a VAZ-2107 you will need:

• stove (homemade, purchased);
• pipelines;
• tees for insertion into the cooling system;
• shut-off valve (to completely shut off the second radiator).

The installation algorithm is relatively simple and includes the following steps:

1. Drain the coolant from the engine.
2. Place and secure the stove in the chosen location
3. We cut tees into the cooling system pipes
4. Install the shutoff valve on the supply pipe
5. We connect the radiator to the cooling system using pipelines through a tap according to the selected circuit (series, parallel). We place the tubes laid throughout the cabin secretly (in places where they are not visible and the likelihood of damage is low).
6. We lay the power wires for the stove fan and install the control button.
7. We fill the cooling system with antifreeze and check the connections for leaks.
8. We remove air pockets from the cooling system.
9. We check the functionality of the second stove.

Popular models of autonomous car heaters

We list the most popular devices, the operation of which requires connection to the on-board power supply:

• Planar 4D is an air-type heater that runs on diesel fuel. The 4 kW model allows you to regulate both the temperature and the speed of the air flow supplied to the cabin. Modification 4D-12, as the name suggests, is suitable for use in passenger cars, since it requires connection to a 12-volt battery. A more productive modification, Planar 4D-24, runs on 24-volt batteries and therefore can be used to heat buses and heavy trucks, as well as special equipment. Electricity consumption is at the level of 4 A/h, which is quite acceptable when using a battery with a capacity of 150 A/h. The cost of the heater is from 190,000 rubles;
• Webasto AIR TOP 02000ST is a series of popular air-type autonomous heaters from a well-known global manufacturer of automotive components. With a thermal power of 2 kW, these devices can operate on several types of fuel. It is possible to adjust the temperature and air flow speed. Electricity consumption, as in the previous case, is 4 A/h, so if used in a passenger car, it is recommended to install an additional battery with a capacity of 75 A/h. The average cost of heaters of this series is 450,000 rubles;
• Hydronic B04W SC is one of the few popular representatives of liquid-type heaters, which is often used as a pre-heater. It runs on gasoline, the thermal power of the device is 4 kW. During heater operation, this indicator can be adjusted in the range of 1.50-4.50 kW. Can be used on cars with a gasoline engine up to 2.0 liters. Electricity consumption depends on the level of generated power and averages 2-3 A/hour. That is, a battery with a capacity of 75 A/h will be drained in approximately 15 hours of continuous operation. The cost of the model starts at 32,000 rubles;
• Trumatic E02400 is an air-powered auxiliary heater powered by LNG and generating heat with a power of 2.5 kW. In this operating mode, gas consumption is 100 g/hour. An important advantage of the model is low energy consumption (about 2 A/hour). The obvious disadvantage is the complexity of installation. Can be used for heating both passenger cars and trucks. Costs about 100 thousand rubles.

We tried to include in our review the maximum number of varieties of autonomous heaters with a description of their main technical characteristics. Based on this data, you can decide which device will be most suitable in your case.

How to make your own heater from a cast iron battery

To heat some small rooms, you can make a homemade air heater powered by electricity. When carrying out work, follow all rules.

To assemble the structure you will need the following components:

• Sealed cast iron battery;
• Heating element (heating element);
• Temperature regulator;
• Battery plugs and taps.

If the battery is old, then it is necessary to clean it of dirt (rinse and paint). After preparing the supporting structure, screw the heating element into the lower part using a sealing gasket.

On the reverse side of the structure, using a special fitting, a Mayevsky crane is mounted. After this, using a hose, the battery is filled with water (completely). To do this, unscrew the top tap through which filling is carried out.

Note! One section of any cast iron battery is approximately 1.5 liters.

Next, to connect the heating element, a flexible cable is laid. The characteristics of the cable must correspond to the power of the equipment. To set and further automatically adjust the temperature, the connection is made via a thermostat.

To ensure the safe operation of the device, a protection device is required for the heater contacts.

It is worth noting that the oil radiator, or rather its body, is not suitable for this design.

Characteristics of an autonomous heater

Installation of an autonomous heating system for the car interior

Let's start with the characteristics of a gasoline, diesel or electric 12-volt JSC. It should be noted that in practice, a gasoline autonomous heater is one of the most reliable. If necessary, the driver can only activate the interior heating, and not all elements of the vehicle. The auxiliary heater can be equipped with various functions, including a timer, as well as a pre-start device. When operating an AO, the cabin or interior of the vehicle can be warmed up in a few minutes.

What kind of AO device (let's look at the example of a diesel unit):

1. Unit with combustion chamber. This component is one of the main ones in the operation of the system.
2. The autonomous interior heater is equipped with its own gas line, which connects to a common line and supplies the system itself, depending on whether the engine is functioning or not.
3. The exhaust system, which is equipped with an autonomous interior heater, is designed to release exhaust gases. The gas can be released behind the fender liners or under the engine.
4. The device also includes clamps for installing it in the engine compartment.
5. One of the main design elements of the parking heater is the control unit. This component can be push-button or remote; it is installed inside the vehicle.
6. Other elements designed for correct operation of the system in various conditions. Their availability depends on the specific manufacturer.

This is a very convenient thing, which, moreover, extends the life of your engine!

Principle of operation

How does a 12 or 24 Volt petrol or electric parking heater work? The principle of operation of such a stove is similar to the principle of operation of a conventional hair dryer - the system simply heats the air flow entering the car interior as a result of fuel combustion. Depending on the type of system, fuel consumption during operation is around 100 grams per hour, but this figure may be different, depending on the manufacturer (video author - Alexander Termokirov).

The operating principle is as follows:

1. First, thanks to the fan, cold air flow is driven from the vehicle interior.
2. This air flow is heated in the combustion chamber of a gasoline, diesel or electric AO at 12 or 24 Volts.
3. After heating, the air again enters the cabin.

As for the types of AO for a car, there can be three of them, depending on what part of the car they will heat:

1. Air. Autonomous air heaters allow you to warm only the air inside the vehicle. As a rule, this type of AO is a traditional fan that simply heats the air.
2. Liquid. A liquid-type parking heater is designed to warm up the cooling system if it is not started by the engine. It can also heat the fuel system, which is equally important for engine-powered vehicles.
3. Oil. This parking heater is designed to warm up the oil line of the vehicle. The operation of such a system will speed up and also simplify the startup of the power unit during cold weather.

Interior heating kit

Also, stoves for warming up the cabin and interior of the car can be divided according to the method of power supply:

• gasoline ones, which run on gasoline;
• diesel, operating, respectively, on diesel;
• electric 12 or 24 Volts, powered by current.

Installation of an additional stove in the cabin occurs in several stages:

• Preparing the installation site. Most often, given the rather large dimensions of the device (depending on the power, respectively, the more powerful the larger in size) it fits into some niche. Since passenger vehicles are often provided with free space in the cabin, this place most often turns out to be the space under the seat. This arrangement allows, in addition to saving space in the cabin, to effectively distribute air flow and effectively heat the space; Then you need to lay pipes from the device to the standard ventilation system (connect one to the factory pump and the other from the cylinder head);
• Power supply in budget options is most often provided through a standard system (from the cigarette lighter). This ensures production savings, since products powered from an inverter or from a fixed network must have a different device with additional elements, and accordingly the cost of the entire device will be higher.

Installation locations, connection diagrams

You can purchase an additional stove for the VAZ-2107 or make it yourself. The design of such a heater includes a radiator, which is connected to the cooling system through pipes, and a fan that creates air flow.

If you decide to install an additional heater radiator, first of all decide on the installation location. There are three optimal locations for installing equipment:

1. Under the front passenger seat
2. Below the front panel under the glove compartment.
3. On the center tunnel between the front seats

The location should be selected based on the overall dimensions of the stove.

The next important condition is the connection diagram. You install the additional radiator in series with the standard one (the drain pipe of the standard one acts as an inlet for the additional one). The disadvantage of this connection is the weak heat transfer from the other heat exchanger, since it will receive antifreeze, which has already given off some of the heat.

An additional stove can be connected in parallel to the standard heater (the supply and drain of the second radiator cut into the corresponding pipes on the main stove). The negative side here is the likelihood that the main flow of liquid will flow only to one radiator; in this case, the second one will heat poorly.

Homemade hair dryer or 12 Volt car heater

Making a 12 V car heater with your own hands is a fairly simple task that does not require special skills or expensive components. The only thing is that it is not always needed for its intended use.

Main components for the heater:

• Power supply from a computer;
• Small fan;
• Tile;
• Bolts and nuts;
• Nichrome wire.

The main part of a car heater is the housing in which all the components of the device are installed. In order to make a case, you need to remove all components from the computer power supply (cooler, board with various circuit elements and wires). It is worth noting that in addition, you need to remove all plastic elements from the block.

Next, to carry out heating, you need to make a heating element from nichrome wire. To do this, take any cylindrical object (pencil or pen) onto which this wire is wound to form a spiral. The use of this type of wire is due to the fact that this alloy has a very high resistance value.

According to the resistance force of the heating element, the connection diagram to the vehicle's electrical network is selected.

Next, we prepare the surface on which the spirals will be located. In ordinary tiles, holes are drilled, to which heating elements are screwed using bolts.

Description of the autonomous heater

To begin with, let's look at the basic description of the additional 21-volt car interior AO. Such devices can fall into the category of gasoline, diesel or electric, and the former, as practice has shown, are considered one of the most reliable . Such a device can have many useful functions, in particular, it can be equipped with a pre-start device, as well as a timer for turning on the joint stock at a certain time. If the heater is effective, then in practice, unlike a stove, it will be able to warm up the car interior in just 2-5 minutes after starting the engine.

We suggest that you familiarize yourself with the design of an autonomous heater using the example of a diesel engine:

1. The main device equipped with a combustion chamber. The combustion process of fuel takes place here, which ensures good heating of the car interior.
2. A fuel line is equipped with every diesel or gasoline company. This line is connected to the common fuel line. The operation of this line depends on whether the car engine is running or not.
3. The autonomous device is also equipped with a special exhaust system, its purpose is to release exhaust gases into the environment. Depending on the design features, gas exhaust can be carried out both behind the fender liners of the car and into the engine compartment.
4. Fastenings for mounting a heating device in the engine compartment.
5. Control module - this component is considered one of the most important and basic of those found in the design. In essence, it serves as the “brains of the system.” The control module itself can be push-button; recently, remote versions of the units are increasingly used. That is, the system is controlled using the remote control. As for installation, this component is located inside the car.
6. Also, the configuration and design of the AO may include other parts and components that will ensure optimal functionality of the system in any conditions. The list of these devices may vary, in this case it all depends on the specific manufacturer or model.

Principle of operation

Now let's move on to the question of the principle of operation of the stove. In general, the principle of operation can be compared with the principle of operation of a household hair dryer. In particular, the device allows you to effectively warm up the air that enters the passenger compartment or cabin of the vehicle; the heating itself is carried out due to the combustion of fuel. On average, fuel consumption when operating a parking heater varies around 100 g per hour, but this value can be higher, it all depends on the specific manufacturer.

As for the operating principle itself, it looks like this:

1. First of all, the fan starts, with its help air from the car interior enters the combustion chamber.
2. Next, the air is heated after it enters the combustion chamber.
3. When the air flow is warmed up, it will again be sent into the car interior (video author - Alexander Termokirov).

Varieties

As mentioned above, heating systems are divided among themselves according to the method of power supply: gasoline, electric and diesel, but there are three more types of devices.

Features of work

How does an air planar work? When the fuel is burned, the interior heating starts working. Thus, all the walls of the combustion chamber begin to heat up and emit heat, and the air fan begins to drive cold air around the chamber and returns it back already warm. Each air Planar has a control panel with which you can turn on and off the autonomous heating in the cabin. After starting the entire system, the combustion chamber is first purged, and then gradually warm air begins to fill the car interior. In fact, the operating principle of this device is similar to the operation of a hair dryer, which is why very often drivers in “their circles” call the Air Planar

Autonomous heating for a car can be purchased either in a specialized store or simply online. buy Planar , as you can find all the important information, descriptions of the equipment, reviews and help from consultants on it. of autonomous heaters are now sold, as companies are trying to produce new models that all drivers could afford. Some of the most common models of autonomous heaters are: Planar 2D , Planar 4DM2 and Planar 44D . Thanks to the wide selection, you can find an auxiliary heater that is ideal for any car. Moreover, Planar 4DM is the most optimal option suitable for both a car cabin, a minibus interior, and a van with a volume of up to 20 m3

Installing an autonomous heater Planar 2 D requires a serious approach.

Is it that simple?

Given the apparent simplicity of the heating principle, an air-powered auxiliary heater can hardly be considered as an additional interior heater that can be manufactured with your own hands. In conditions of home-made production, it is practically very difficult to fulfill the requirements:

• to the quality of welding of elements, taking into account the specifics of the thermal load and deformation of the mating elements;
• to the reliability of control systems necessary for the operation of an autonomous heater;
• to prevent deviations from the specified combustion mode, the formation of a large amount of carbon monoxide, burning of the chamber walls and, as a consequence, mixing of combustion products and heated air;
• to ensure control of the launch procedure without the risk of fire.

Another heating option

The classic version of an autonomous heater is a scheme where two circuits are simultaneously assembled in the heating device - an engine antifreeze heating circuit and a heat exchanger for the coolant sent to the cabin heating system.

There are options for an autonomous heating system with minor modifications that have a connected thermally insulated container or hot water tank in the interior heating system. Such a boiler plays the role of both a heat accumulator and a source of hot water. An additional pump pumps and heats the container operating in boiler mode. This type of autonomous heater is most often used for mobile living quarters - mobile homes.

Video on the topic

It is quite possible to make a practical and convenient heater with your own hands, without resorting to the help of specialists. To heat the air in rooms, various devices are used. They are distinguished by many parameters, the type of heating element, power and the use of additional functions, such as equipping the device with a fan. These parameters also affect the prices of these devices. In order to save money, you can make the device yourself.
