Electric foot heater for home and office: characteristics of devices, TOP best models

On the VAZ 2109 the stove does not blow at your feet

Heating problems often arise in VAZ cars, both old and new models. The manufacturer did a rather poor job on a system that is so important in the harsh Russian climate, so car owners are often forced to fine-tune the heater themselves.

What should you do if for some reason the heater on your VAZ-2109 does not blow at your feet? Read about it below.

General information

Poor airflow is mainly caused by those modifications that have a high panel installed. Often faced with a situation where warm air does not reach their feet, owners begin to change the main elements of the heater one by one:

radiator;
faucet;
pipes, antifreeze, etc.

Having spent a lot of money on this, they do not achieve any noticeable improvement. Meanwhile, the reason here is very simple. Most often, this happens due to incomplete closure of the central sand damper.

The problem here is that the outlet for the foot airflow is located below the previously mentioned part and therefore, if its seal is broken, cold from outside enters there. At the same time, excessively hot air is blowing into the driver’s face, and his legs are cramping from the cold.

The VAZ-2109, which has a low panel, is practically free from such a drawback. The thing is that they were equipped with heaters of a slightly different system, more simple and reliable.

How the VAZ-2112 stove works

The functions of the stove include not only heating the air flow, but also ventilating the interior. When the fans are turned off, air naturally enters the car through air ducts located in the cabin.

Ventilating and heating deflectors are equipped with special valves that are required to ensure that air does not escape back out of the cabin. Accordingly, fresh air must flow freely through the air channels.

Unlike classic VAZ models, the 2112 does not have a tap in the system. The damper is responsible for regulating the air temperature, which also limits the volume of incoming air.

Coolant is always present in the stove. This design feature forces car owners to think about installing an additional tap to prevent the stove from heating up in the summer.

According to the data sheet, the adjustment accuracy is approximately ± 2 degrees. As practice shows, this is not true. Accordingly, owners install taps so as not to get burned in the summer. The main disadvantage of the faucet is its tendency to oxidize.

In winter, heated air flows primarily onto the windshield. This is where the main flow goes. The rest goes under the feet of the driver and the passenger sitting in front.

In the VAZ-2112, rear passengers are not heated. There is only a floor-level air duct that supplies air to the rear of the cabin. The main reason that the stove does not blow into your feet is the lack of volume and heating power of the air. Structurally, the heating system is not designed for such productivity.

Fixing the problem

We can immediately say that the easiest way to ensure access to heat to the legs is to muffle the central hose that supplies heated air to the cabin. The only trouble is that in this case, the main problem will not be eliminated, and the overall heating of the cabin will stop

It doesn't work properly, which is also not very good.

The second method will be much more effective. Its essence is to improve a poorly functioning damper. It is necessary to ensure that it blocks the central air sleeve well and redirects heat directly to the legs.

Work order

In this case, it is not necessary to disassemble the stove. It is enough to simply dismantle the torpedo, and then the upper flap, to gain access to the problem area.

A rectangle of 50 by 120 millimeters is cut out of foamed self-adhesive polypropylene. It is best to take the one produced by the STP company (the required type of the most suitable material is called “Accent”).

The workpiece is installed directly inside through the upper hole without removing the protective coating. If you do this right away, it will be much more difficult to place the rectangle, because it will begin to stick to all surfaces. After laying it from below, a narrow slit is cut into the material, approximately 10 mm wide and long to the edges of the hole. Now the flap will fit as tightly as possible.

After this, you can return the torpedo to its place, additionally sealing all its edges with “Accent”, cut into narrow strips. They also need to turn off the air supply to the rear seats. This heating option is installed on cars with a high panel. In older models there is no need to do this.

Results

Having completed all the work described above, you will achieve uniform distribution of air over all side arms with the damper fully open. Moreover, the central air vent will now be closed tightly, and the heating of the windshield and legs will increase several times.

Electric mat

This is the most convenient and versatile option for a heating pad. Such a device does not differ in appearance from a regular rug, but has a special design, which includes:

a heating element;
cover in the form of a cover;
plug with cord.

Create a cozy atmosphere in your home with electric foot mats.
The heating element is made of flexible metal, allowing you to move and roll the mat without damaging it.

The cover is the mat itself, which also protects the heating element from moisture.

Foot heating element:

The foot heater in the form of a mat comes in two versions:

infrared;
standard (electric heating pad).

Infrared heaters are the most popular among buyers. Like any device with infrared radiation, the mat works by heating the objects around it, thereby creating heat from them. That is, the floor and furniture around the carpet will be warm.

Heated mat: Modern models are equipped with thermostats and allow you to set the required temperature.

The foot warming mat has a number of advantages:

small size;
mobility and the ability to easily move from place to place;
efficiency (electricity consumption is no more than 50 W);
ease of use;
operational safety;
Quite a long service life, reaching 15 years.

How to choose a heater:

VAZ 2109 stove low panel does not blow into the feet

Look at the cables and the heater, just so the dampers need to be looked at normally with the heater removed, it can open to the center and glass and it’s cold on your feet.
And there is a damper that lets air past the stove. Near the gas pedal. We need to close it. It can't be closed with a rope, that's their disease.
Found the problem!!! All because the central flap is shorter than necessary!! Maybe it’s like this from the factory! In general, when I close it on my feet, it opens, but it’s not long enough to block and not let air out through itself! In general, I glued plastic to it so that it completely covers the center !Now there is a breeze in your feet, be healthy =)) Thanks for the advice!
the lower lever (left position is cold, right position is hot) in the hot position the damper does not reach all the way, cold air does not flow through the radiator, there is no need to disassemble the panel, use your hand to feel where the cable goes, if the end lever (where the cable goes) is loose, you need to shorten the cable, so that the damper closes all the way! touch the radiator pipes (in the cabin) if they are hot, then the problem is in the dampers, if they are hot but blowing weakly, then the stove or filter is clogged, in cars after 2000 they installed a filter under the hood on the stove, it it gets clogged up quickly, in winter it needs to be removed (unscrew two screws), it’s removed, you have to blow into the interior for so long that the candle flame blows out))), well, it’s kind of detailed! If there’s anything else, ask in a private message!
there the damper doesn’t go all the way, I had to remove the panel almost completely), to make sure, a friend then just shortened it to 99 without taking it apart, it’s also a hot mess!

Causes of poor foot airflow

Heater malfunction

Air through the cabin filter is taken from the street by the rotating blades of the electric heater motor. Through a damper system, air is distributed through air ducts and supplied into the cabin through deflectors and non-adjustable grilles.

Air, like any gaseous medium, tends to follow the path of least resistance. Therefore, it is logical that the air flows first come out of the central and side deflectors. The feet of the driver and passengers are blown last. Structurally, the air ducts to the central deflector and the upper side airflow points have a larger cross-section, and it is much easier for air to pass through them.

Initially, you need to make sure that nothing interferes with the intake of air from the atmosphere. After all, if the air is supplied in insufficient volume, then it will not be enough to supply all airflow points with the intensity that was calculated at the design stage of the car.

Check the condition of the cabin filter. To do this, remove the wipers and frill. The cabin filter is located on the right side of the vehicle under the windshield. It is covered with a plastic casing, which is secured with four self-tapping screws. Unscrew the screws and remove the cabin filter. We start the engine, warm it up to operating temperature and check the operation of the stove. If the situation has improved, change the cabin filter and close the issue.

The second common cause is a clogged heater core. In this case, the heating of the interior will be weak, because warm air does not come out of all the deflectors well, and not just into the legs. But the fact is that when driving for a long time, your feet begin to freeze first, so it seems that the problem is in this part of the airflow.

This malfunction is easily diagnosed. We find two pipes for supplying antifreeze to the heater radiator (rubber hoses on the left side in the direction of travel of the car). With the engine warm, carefully touch the two pipes one at a time with the heater running at full power. The difference in temperature between the pipes should be minimal. If one pipe is hot and the second is cold or barely warm, we wash or replace the heater radiator.

Checking the operation of the dampers

There are nine exit points for air flows from the heater on the VAZ-2110:

central deflector;
two side deflectors and two windshield air vents;
heated feet of the driver and front passenger;
two outputs for heating the feet of rear passengers.

In an ideally operating system, the pressure generated by the heater motor is sufficient to create an effective flow to warm the feet. However, over time, gaps form in the joints of the air ducts, and the dampers of the VAZ-2110 heater begin to fit loosely to the body. This leads to atomization of the air flow. As a result, a minimum amount of air reaches the distant exit points.

First, dismantle the panel with the central deflector. It is held in place by four plastic clips. To remove it, simply pry it off one of the sides with a suitable object, such as a flat-head screwdriver. Be careful: the clips are fragile.

Evaluate the operation of the damper. In older cars with a manual damper drive, pay attention to the play in the linkage of the rods. A broken rod system will not allow the damper to fit tightly to the body in the extreme position, which will cause air to leak from the cold circuit. The problem is corrected by adjusting the damper. In a mechanical drive, it is possible to shorten the rod due to a movable lock on a gear rod or a threaded tip. During the adjustment process, check that the position of the switch on the panel corresponds to the actual position of the damper.

Another reason why the VAZ-2110 stove does not blow into your feet is a malfunction in the operation of the automatic heater control system (AHC) unit or the gear motor of the VAZ-2110 stove. In this case, there is usually insufficiently warm or even cold air from the stove operating in maximum heating mode. This is due to the incorrect position of the damper in which the gearmotor sets it.

Evaluate the operation of the gear motor of the VAZ-2110 stove. To do this, visually check how it closes the damper when switching modes. The easiest way to do this is to remove the panel with the central deflector. Move the temperature knob to the extreme position (for example, set the minimum temperature), then sharply switch to the opposite mode. The damper should completely block the channel visible from the driver's position. If this does not happen, the problem lies in the gear motor or the automatic control system unit. Check the serviceability of the gearmotor and unit.

Heater in the form of slippers or boots

If you want to pamper yourself during the cold season, you can buy a heater in the form of slippers. It allows you to warm your feet after a walk in the cold or after a hard day at work in a cool room. You just need to put on your slippers and connect them to the power supply; the heat will instantly spread from your feet throughout your body.

Slippers with electric heating: An electric heater has a positive effect on the body’s condition, infrared radiation stimulates blood circulation and metabolic processes in the human body, relieves leg fatigue.

Warmers in the form of boots have a similar operating principle to slippers. This option is incredibly convenient when you need to quickly warm your feet. For example, this is relevant when vacationing at a ski resort. You can put a heating pad on anywhere and get completely warm. You just need to find an outlet.

Many heating boots are equipped with control panels, which makes their operation even more comfortable. Modern models have a massager and turn the device into a real find.
