With the onset of cold weather, car owners can often face a very unpleasant situation when, after turning on the stove, the interior does not begin to fill with warm air, although the regulator and the blowing force are set to maximum power. There are many reasons why it can happen that the stove does not heat up. To solve this problem, it is necessary to correctly diagnose the breakdown.
Check the health of the elements responsible for the temperature in the car to prevent it from freezing completely
The main causes of problems
Today, liquid cooling is the most common way to remove excess heat from the engine. The hot liquid passes through the pipes to the heating radiator.
An integrated fan draws in air from the outside and then passes it through the cooler and cabin filter. This is how the air in the car begins to warm up.
Remember to keep an eye on the coolant level in your car
There are two large groups of reasons why the stove does not heat up.:
- malfunction of the heating system;
- problems in the cooling of the car.
It is necessary to take into account the objective reasons due to which the stove does not heat well. In the cold season, when the temperature reaches -15 ° C, warm air will begin to flow into the cabin only after a while. The car needs about 15 minutes for the heat exchange fluid to warm up well (up to + 40 ... + 70 ° С). Only then will full heating begin.
Modern vehicles are often equipped with a climate control system, air conditioning, stoves, which start their work only after the antifreeze has completely warmed up.
The main reasons for a stove malfunction:
Defective engine pump
A pump is essentially a mechanical (sometimes electric) engine pump that pumps hot liquid through the system. That is, from the power unit block, through the pipes and further into the radiators for cooling. And in our case, and for heating the passenger compartment.
It is a "impeller" that is inserted into a metal cylinder through which fluid passes. The impeller rotates, thereby pushing the antifreeze (TOSOL) through the system. If there was no pump, the cooling of the motor would be extremely ineffective, it would quickly overheat.
Very often, the pump is driven by a belt drive from the crankshaft of the power unit.
The main breakdowns are as follows:
Fast diagnostics
There are many factors due to which the stove does not heat well. The reasons may be hidden, for example, in the thermostat. Air may enter the cooling system. It reduces the circulation performance of antifreeze, while creating a kind of plugs.
The main reasons why the stove does not heat well:
- Thermostat jammed.
- The liquid intended for cooling the engine does not circulate well in the stove radiator.
- Air pockets in the cooling system.
- The electric heater is out of order or there is no power supply. This problem can occur in vehicles that are equipped with electric heating.

These are the most common reasons that the stove does not heat well. In reality, things can be much more complicated. For example, antifreeze will leak, which will lead to a decrease in the coolant level in the system. This happens when the cooling radiator or connecting pipes are damaged. Hot air may not pass well into the passenger compartment due to a malfunction of the air duct or ventilation valves.
10 reasons why the stove does not heat well:
Heating system
The main element of the car's heating system is the radiator. It has the function of heating the outside air. Diagnostics should start from this part.
Vehicle heating system: If you add antifreeze or antifreeze from another manufacturer to the coolant, this can lead to the formation of solid deposits. They begin to clog the channels that supply heat. You can solve the problem like this:
- Purchase a new heater.
- Flush the radiator. You can do this yourself. It is necessary to use a working solution: 50 g of citric acid is diluted in a liter of warm or hot water. If possible, pressurize during flushing.
- Swap the pipes. This often helps if a solid precipitate has formed. This procedure temporarily improves the quality of the heaters.
It may be that the radiator heats up well, but the stove does not work. The most common reason is a breakdown of the electric motor, which is necessary for the rotation of the fan. To solve this problem, it is necessary to replace the non-working element.
Diagnostics of the stove in the car: Another reason that the stove does not heat up may be a malfunction in the electronics or in the control system. Power buttons or temperature controls may break. You can solve the problem in the following ways:
- Buy a new part to replace the broken one.
- You can put the damper in the "open" mode.
- Set the temperature as high as possible, and then disconnect the terminal on the battery. Set the minimum value. Make sure that the adjustment works correctly.
The stove may not heat well due to a blockage in the cabin filter. The solution is to replace this part.
The main reasons why the stove does not heat up:
Cooling elements
The heating in the car may not work due to malfunctioning of the cooling system. Very often the thermostat is the problem. This is a device that ensures the correct movement of the heat-dissipating fluid in the system. If the thermostat breaks down, the antifreeze cannot heat the interior radiator in a short time. The only solution can be to replace the part.
The reason for the poor functioning of the oven can be a low level of heat exchange fluid. When there is not enough antifreeze in the system, little of the heated liquid enters the radiator. This causes poor air heating. To fix this breakdown, you need to find a place where the heat exchange fluid flows out. Then the leak is eliminated and the required amount of antifreeze is added to the system.
Reasons for poor functioning of the stove: The ingress of air into the system adversely affects the functioning of the stove. Ventilation can occur for a number of reasons: violation of the integrity of the gasket, leaks in the pipes, etc. To diagnose the problem, it is necessary to measure the amount of antifreeze in all elements of the heat exchanger. When the ignition is off, the fluid level should reach the maximum mark. There are two ways to solve this problem.:
- Open the radiator. Perform manual bleeding of the system. It is necessary to pump up the hoses until bubbles appear. Put the radiator cap back on, then start the engine. After a few minutes, the procedure is repeated.
- Raise the front of the car a few degrees (you can use a jack). Open the radiator and conservator caps. Then you need to start the engine and start rhythmically pressing the gas pedal. Do not forget to add antifreeze on time.
Both procedures are fairly straightforward. If you fear that you will not be able to cope on your own, it is better to seek help from specialists.
Stove in the car:
Focus on foundation and floor
Often the reason for the coolness in the bathhouse is the cold floor and the roots of this problem go back to the very beginning of the construction of the building, and they are different for rural and modern buildings.
Rural baths are characterized by a strip foundation, an earthen sub-floor and a leaking wooden floor. From here we proceed in solving the problem.
By itself, the space under the boards does not freeze even in severe frosts (for a chopped bath), therefore, in order to keep our feet from freezing, we do the following:
- Increase the space between the floor and the ground a little. This can be done in two ways - to make the foundation higher or to remove the layer of earth.
- On the inside, sprinkle the concrete / brick tape around the perimeter with sand or expanded clay.
- Arrange a blockage on all sides outside.
- Do not lay the floorboards close to the log house and to each other; we also leave a gap near the stove.
- Make the floor slightly higher than the base of the heater.
All this may not help modern frame buildings, as well as from bricks or blocks, especially since in most of them you will not find a simple drainage of water to the ground. They are equipped with concrete bowls with a system for collecting and draining water to the outside. Moreover, many began to do this not only in the washing room, but also along the entire contour of the bath.
In such buildings, t under the floor is often equal to that on the street, i.e. at -20 grams in winter, after a week of your absence, you will have almost the same amount under the floor. What happens - you heat the stove, after an hour and a half it's already hot, but it's still cold below.

It is better not to insulate the foundation from the inside with various kinds of foam-based materials - this threatens the appearance of condensation on the surface of the tape. It will be very effective to include the floor in the ventilation system. We make the floor leaky in the sink (in this case, a special hole is not needed) and partially the same in the steam room.
Those who have a monolithic screed can only be advised to lay a water or electric floor, the inclusion of layers of insulation in the base will not give the desired effect.
Preventive actions
In winter, the stove in the car performs an essential function. In order for it to function normally and not break, it is necessary to adhere to several recommendations.
Periodically check the serviceability of the car at the service station, this will allow you to find and eliminate problems in advance
Preventive measures:
- Keep the radiator clean. External dirt must be removed with a vacuum cleaner. For internal cleaning, the cooling system and oven radiator should be flushed regularly.
- It is worth pouring in high-quality antifreeze. It will be useful not only for the stove, but also for the engine as a whole. We must remember to replace the fluid in time.
- You should buy a new cabin filter as often as possible. If this element is clogged with dirt and dust, this negatively affects the functioning of the entire ventilation system of the vehicle as a whole. An uncleaned filter can be dangerous to humans due to the appearance of various microorganisms.
If the outside temperature drops below -25 ° С, and the car stove heats the air in the cabin to + 15 ° С, then this means that the equipment is working normally. To avoid problems with the heating system of the machine, you need to take preventive measures on time, and also remember that the performance of the car's heating system directly depends on its age. The older the car, the more attention you need to pay to it.
What would the stove be better heated:
It's all about the stove
You need to start with it, because it is initially a source of heating. The type, design and location of the oven, of course, play an important role in this.
There are usually no problems with good heating in factory heaters, which cannot be said about home-made ones.An improperly cooked such oven, instead of saving, can bring some problems. The absence of an ash pan, a deflector, a poorly designed firebox or chimney leads to the fact that water and stones simply do not reach the desired temperature.

A bathhouse with just such a stove - as long as it is heated, it seems, and nothing, as soon as the wood burns out, it immediately becomes cooler. Therefore, it is very important to properly dispose of the heat received from the wood: the fire should not just fly into the chimney, it should warm up the tank with water and the niche with stones.
- the water tank should be placed on top of the firebox, and not on the side, - make the stones straight, - close the bowl with stones completely or partially, - put a valve on the chimney pipe.
Factory heaters usually have no problems with this, but there is another problem - they do not keep warm. Why is this moment so important, but everything is simple - there is not enough fast heating, you also need to keep warm for a long period, otherwise it will be a bathhouse for one.
This is achieved by increasing the amount of material capable of storing heat and giving it away gradually, and not instantly, as in the case of metal. In expensive models, this function is performed by casing convectors made of stone; for budget products, the solution will be: partial lining with bricks, hanging a samovar-type water tank or mesh with stones on the chimney, transferring the chimney channel from the center to the side or to the back wall (if provided design).
It will not be superfluous to read the instructions, although many do not like to do this. For example, some manufacturers indicate that the maximum t is achieved by completely filling the firebox with wood and completely opening the ash pan. In general, consider the characteristics of your heater and learn how to use it correctly.
We suggest that you familiarize yourself with: How to make a frame for a canopy in a bath
We should not also forget about the performance of the stove, because each model is designed to heat a certain volume of a bath / steam room. When purchasing or making a heating device, you must always think about whether it can provide the required temperature regime.
As for those made of bricks, the situation is this - good heaters heat up quickly enough and retain heat for a very long time. But such creations are an expensive pleasure, because not every stove-maker can competently fold, and he will take a lot for his work.
That is why, many try to lay out the stove themselves and the result is not necessary for everyone. When laying them on their own, mistakes are often made. Incorrectly executed smoke circulation, furnace lining or the wrong section of the well guarantee weak or too long heating. In this case, you can propose to make a combined oven.
