When designing your home, you need to take care of the future heating system. After all, the comfort and health of all residents of the house depend on high-quality heating. In order for the heating system to work effectively, you need to select a suitable heating boiler and install it in the system in compliance with all rules and technologies. If the boiler is installed incorrectly, various types of problems may occur in the future. The most common problem is the heating boiler turning on and off frequently. But not everyone knows the possible causes of this problem. Therefore, in our article we will consider the reasons for frequent turning on and off of a gas boiler, as well as ways to eliminate them.
Possible reasons
There are times when you purchased a new boiler, installed it and started using it. But it starts turning on and off randomly. Of course, it must regulate its operation itself, but there should not be frequent shutdowns. In this case, it is necessary to understand the reason. After all, this indicates the presence of some problems. If the device is often turned off and on, its service life is significantly reduced due to wear of the working parts. And, consequently, the boiler will fail.
There are several reasons for frequent shutdowns of the heating boiler. But if you do not understand gas boilers, it is better to contact a specialist.
Let's look at the possible reasons:
- The boiler power is designed for a larger area than there is in the room.
- The circulation pump is not installed correctly.
- The boiler is not selected correctly.
- There is no thermostat in the room. The boiler is regulated according to the temperature of the coolant.
- The temperature range is incorrect.
The problem is not complicated, but sometimes it requires replacing the gas boiler.
BAXI error e01. Control board fault
As a rule, if the above checks have been performed and do not reveal a problem, then diagnostics and repair of the boiler board will be required. In the case of Baxi boilers, the ignition unit and modules responsible for modulating the flame are located on the board itself, so their breakdown can lead to error E01. Diagnostics of the control board can only be carried out by a qualified specialist.
You can also watch a short video that shows in detail and clearly the checks discussed.
If you still think that the cause of error 01e
is a breakdown of the electronic board - contact us, we have everything you need to diagnose and repair the boards of BAXI gas boilers: specialist, experience, spare parts, equipment for professional installation. It is possible to deliver boards to other regions of Russia and organize repairs by agreement.

Excess power
Under no circumstances should you install a boiler of greater power than required for a particular room. It is necessary to accurately calculate the required power. After all, a lack or excess of power can negatively affect the operation of the equipment. Therefore, if you were unable to independently calculate the required power, then you can turn to specialists who will correctly carry out all the calculations.
But in order to determine the power, it is not enough to know the area of the heated room. The following factors influence the power value:
But there are many resources on the Internet where you can find online power calculations. You can use them for an approximate calculation.
But if you bought a heating boiler and noticed that the power is much more than required, then you need to solve this problem. First you need to find out how often the boiler can turn on during normal operation. In order to ensure normal operation for a boiler with increased power, it is necessary to install a four-way mixing valve in the hydraulic system. This option will show excellent results. But you will also have to spend a considerable part of your funds.
If your appliance has a multi-stage burner, then you can try the method of lowering the burner.
Another way is to connect the boiler to the boiler. In this option, in addition to reducing the power of the gas heating boiler, it will be possible to provide the house with hot water supply. In order to determine the power of a single-circuit and double-circuit heating boiler, it is necessary to use different schemes. It is better to choose boilers with the minimum power required to heat your home.
In order to correct the problem of frequent boiler switching on, as well as reduce fuel consumption, you can use a thermo-hydraulic distributor instead of a mixing valve. It costs a lot more, of course, but the result is much more effective.
Selection and configuration of equipment
Issues regarding the operation of the heat supply system of a private home, in contrast to centralized systems, fall entirely on its owners . And one of the problems that has to be solved is the issue of correct selection of gas equipment.
Experience in operating systems shows that a properly selected boiler should operate for at least 30% of the heating period.
The average value of boiler power consumption per square meter of a heated room ( with a ceiling height of up to 3 meters ) is about 100 watts.
Practice also shows that installing a boiler or burner with too high a power can create many problems associated with excessive gas consumption, difficulty in selecting the temperature in heated rooms and the reliability of the system.
After selecting and installing the heating system, as well as each time it is started, the following adjustments are made :
- Complete heating of the boiler.
- Full opening of the chimney damper.
- Setting the burner flame to maximum power (the flame should consist of blue and yellow segments).
- Shut off the gas supply valve when lowering to remove the yellow segment of the flame .
- Checking the safety automation and operating modes of the boiler.
Important! Setting the correct flame color of a gas burner is key to complete combustion of gas without the formation of soot that settles on the walls of the firebox and chimney, reducing the efficiency of the system and increasing gas fuel consumption.
How to adjust burner power
If the burner significantly exceeds the boiler in power, it may not have enough firebox volume , air flow through the dampers and from the pressurization. In this case, the combustion of the flame becomes uncontrollable, and the burner flame turns yellow.
Incomplete combustion of gas fuel causes soot in the firebox and chimney with combustion products, and part of the energy is dissipated into the surrounding space, increasing fuel consumption.
Photo 1. The shut-off valve helps regulate the gas supply in case of problems with the boiler.
In this case, the burner power can be reduced by closing the gas supply valve when lowering.
However, if the power is constantly set to the minimum value , this will reduce the efficiency and range of adjustments of the system.
Reference! When choosing a gas burner, in addition to the dimensions of the combustion chamber and the geometry of the torch , it is important to take into account the compliance of the passport values of the minimum and maximum power and methods of its regulation, as well as the gas consumption of the burner.
High gas consumption
The reason for high gas consumption is often the ineffective operation of the boiler heat exchanger. The coolant passing through the heat exchanger carries with it particles of scale and salts, which can be deposited on the internal walls of the heat exchanger, reducing its thermal conductivity and increasing the amount of fuel required for heating.
Typically, a problem with a heat exchanger is manifested by a characteristic noise emanating from a working boiler, reminiscent of a whistling or gurgling sound, similar to a kettle boiling.
In this case, you will need to manually clean the heat exchanger or wash it with a special compound.
The reason for high gas consumption can also be its reduced calorie content , caused by insufficient drying by the gas distribution company. The norm of the lower calorific value of household gas must be at least 7600 kcal per cubic meter , but in practice the calorific value of gas can be reduced to 4000 kcal.
Important! When purchasing gas equipment, it is important to take into account the composition and minimum pressure of the gas in a particular gas supply system so that the equipment operates reliably.
Thermostat device
Another common reason for the heating boiler turning off and on frequently is the lack of a thermostat. This means that the device is regulated only by the temperature of the coolant. When the water is heated to the desired temperature, the boiler turns off. And after the water begins to cool, the boiler turns on again. But the problem is that the air in the room takes longer to cool than the coolant. With this method of controlling the device, fuel consumption increases significantly. And the air temperature in the room will be elevated, and it will be uncomfortable to be in it. Therefore, it is necessary to install a thermostat. With its help, the heating gas boiler will be automatically controlled. After installing a room thermostat, fuel consumption will decrease and heating will become more comfortable and efficient.
After the air temperature in the room becomes below comfortable, the gas boiler will turn on. Thus, the air in the room will always be comfortable, and fuel will not be consumed more than expected.
There are many thermostat options on the market that come with varying prices and features. Budget options would be mechanical room thermostats. But they are reliable and do not require special care during operation. Modern programmers have a more complex device. They can be given different options and set different temperatures.
In order for the heating system to function correctly and not consume excess fuel, it must be installed correctly. If the boiler is controlled by a room thermostat, then you will not need to monitor the device’s switching on and off. This way, you will save on fuel consumption, and the gas boiler will last longer.
The boiler goes out
Common reasons why a gas boiler goes out include:
- Pressure drop in the gas pipeline;
- Problems with the chimney (clogging);
- Failure of the gas meter and sensors in the boiler;
- Gas leaks and lack of traction;
- Blowing wind into a chimney.
The chimney inevitably becomes clogged with soot, debris, and even birds flying in over time. It needs to be cleaned regularly. However, even if it is absolutely clean, the chimney may simply lose draft due to a sharp gust of wind or improper installation of the chimney as a whole. The wind blew strongly and the torch in the furnace goes out, heating the coolant stops.
The chimney may be clogged and needs to be cleaned.
In some cases, the smoke channel will have to be increased in height. The chimney should not be blocked by trees or the ridge of the roof. At the same time, it should not rise too high above the roof either. There are strict rules. They must be followed accurately when installing a chimney pipe, otherwise the newly installed gas boiler will not even work. The chamber will not have the necessary draft, and therefore no oxygen. And without it, methane does not burn.
Often a gas boiler goes out, simply because the automation switches it off. This is possible due to the detection of a leak by a gas analyzer, the operation of a thermocouple and a malfunction of the meter. That is, protection is activated to prevent fires and breakdowns of heating equipment.
Here you need to look for the root cause - why the protective elements are activated. And only then think about what to do in a specific situation. And often only a specialist from a company servicing gas equipment can identify and eliminate problems. This pumping station for a private home can be serviced with your own hands. Gas-powered equipment must only be inspected and repaired by specialists. These are the requirements of the laws in this area.
Incorrect installation of the circulation pump
Natural circulation of coolant is not always effective, so owners decide to install a circulation pump. It is especially important if heating a two-story house is required. The devices force water to circulate correctly through the heating system, ensuring its proper operation.
The pump must be installed in accordance with all rules. Their violation can lead to failures in the system, which will be the reason why the gas heating boiler often turns on.
To install the circulation pump, you need to choose a place in the system where there is always excess hydraulic pressure.
Violation of the integrity of the mechanism is the reason for frequent operation of the boiler
Note! To avoid problems with the operation of the circulation system, entrust the installation of the circulation pump to professionals.
