Gas boiler timing. On time
what is 17 kilowatts of heat carriers? it should be in liters
17 kilowatts of coolants? This parameter is the loss of OK and in double-circuit, the flow rate for heating DHW.
The on/off time depends on the temperature of the coolant and the internal temperature in the room.
Clocking the boiler, in principle, does not interfere with its operation, but the less often it turns off, the better. The boiler must be adjusted to the system or immediately select the boiler power for the heating system. You can reduce the power by going to the engineering menu or invite a specialist so as not to break firewood yourself.
from domestic conditions and from the weather and from the sensitivity of the boiler ....
Clocking and power of the Immergas boiler
Firm and model of equipment:
Immergas Eolo Star 24 kV
David:
Hello. I really need your advice. I re-read and reviewed a bunch of material, but did not find the answer to my question. Boiler Immergaz Eolo Star 24-kilowatt, CO 4 panel radiators with a total capacity of 7500 watts and a dryer in the bathroom, the coolant in the system is about 40 liters.
Room thermostat installed. The coolant temperature is 75 degrees. Boiler operation: after the boiler is turned off by the thermostat, there is a pause of about 2 hours, the water in the system cools down to 24-30 degrees and after the thermostat closes the contacts, the boiler turns on and runs at minimum power for 5 minutes and gradually increases to the maximum until the water reaches 75 degrees.
Then it modulates to a minimum (set to 45%) and before the thermostat works, it has time to cycle twice. In the menu, I lowered the power to 5% and the boiler stopped clocking
I can’t understand this: when working with a thermostat, in my opinion, it is important that the boiler heats up the apartment faster and that the apartment keeps the temperature longer
The passport indicates that the minimum heating power is 11.5 kilowatts. Which is more profitable in terms of gas consumption: fast heating of the coolant and then work at a minimum to maintain the temperature. The manufacturer does not recommend lowering the power by less than 30 percent due to a decrease in efficiency. What is more important: efficiency reduction or boiler operation without clocking?
Answer:
Hello David. My opinion is that clocking is definitely bad for any unit, including the boiler. Clocking leads to additional wear of the components and, as a result, to excessive fuel consumption and a reduction in the life of the boiler. In addition - thermal shocks in CO, the danger of overheating of the coolant and other troubles associated with improper operation of heating equipment ...
There can be only one reason for the boiler clocking - insufficiently efficient operation of the entire CO. In this case, there can be only two reasons:
- incorrect calculation;
- incorrect installation of CO.
However, not a single heat engineer can take into account all the nuances when creating CO ...
As an option, you can install a modulating burner - a burner with variable power. But this is a "half" solution. It is better to install an additional tank for the coolant - a heat accumulator between the boiler and CO. It will serve as a compensator for temperature changes.
The boiler "pumps" heat into the heat accumulator, and CO - consumes this heat as needed (need). Everything is very simple. Personally, I have 200 liters and there are no problems with clocking).

How to make a gas boiler turn on less often. Boiler automatic clocking
Most of the emergency situations in the operation of the boiler falls precisely during the heating period, when the trouble-free operation of the heat supply system is especially important. Let's try to analyze the main problems and how to fix them based on practical experience.
In the event of a drop in the pressure of blue fuel, the service engineer is unable to influence the situation and it is necessary to contact the gas industry.
Violation of the circulation of the coolant
There are situations, especially in rural areas, when there is a power outage due to an accident or network overload, from several hours to several days. And if the house is not sufficiently insulated, then even two days without electricity can lead to a drop in temperature, and there is a high probability of freezing of the coolant in the heating system. It is very difficult to identify an ice plug in the heating system, even for a specialist who himself carried out the installation. A weak, not insulated place can be revealed both in the attic and in the basement.
Gas boilers, in this situation, often do not go into an accident, with the exception of those models where there is no bypass system. It is activated when there is no circulation in the heating system, opening the "bypass" line. In this case, the heated coolant from the supply line immediately enters the return line, as a result of which the temperature of the sensor begins to rise rapidly, and the burner turns off. In this case, the boiler is switched on every three minutes (factory delay between ignition cycles), for a few seconds. The system remains cold, nearby radiators can warm up a little. Often, when this situation occurs, the owner of the equipment contacts the service department to call an engineer to repair the gas boiler. But the engineer will not be able to fix the problem, since it lies not in the boiler, but in the heating system. Experienced installers solve this problem by dividing the system into separate branches and checking them under flow and pressure in turn.
In order to prevent undesirable consequences, service masters recommend regularly monitoring the operation of the heating system, not relying entirely on automation, and not leaving a working boiler unattended for more than a week. E
