Freezing or defrosting heating system?

inside the heating system. Water expands when it freezes. Literature - a physics textbook for elementary school. And the “batteries” themselves do not freeze. But they are torn apart by water that has turned to ice.
Lena, have you forgotten your school physics? Yes, the freezing is eating, but it’s to blame. The ice breaks, because... its volume is greater than the water from which it is formed. Previously, in villages, sometimes supplies froze in the cellar. And the banks were bursting. In winter, water is therefore drained from heating systems before they are no longer used (repairs/long departures in private homes)
Message from Elena234 : Is there any literature regarding this issue?
Message from Bull : Beduin1978, what does this change in light of the author's question?
In this light the question is unclear

Perhaps TS is just looking for the correct wording?
Message from Vladimir. : Perhaps TS is just looking for the right wording?
Maybe. Then don't:

but simply “ defrosting happened
".
This will be the event that by default suggests a cause. Without additional instructions thereof. Unless, of course, Beduin1978
lied about the term.

And I remember the physics textbook, but in reality it was the following. The water in the “battery” on the 1st floor in the entrance of our house (a decent stalinka, with through passages from the facade to the courtyard) located on the wall, in January, in frosts of -25 (several days), froze, but in the frosts it did not burst, but burst the next day, when it suddenly warmed up to almost zero. It’s good that it was warm and the management company restarted the system within a few hours. What does this mean?
Message from vivol : but it didn’t burst in the cold, but burst the next day, when it suddenly warmed up to almost zero.
do you mean “didn’t burst”? didn't leak in the cold? so it's because the contents of the battery were in a solid state
Posted by vivol : What does this mean?
What exactly is “this”? If it “didn’t burst,” then, as they correctly put it in the previous message, then it burst in the cold. From outside the wall, no one could easily notice this sound. And they only noticed it when it started leaking.
And if we mean the presence of VISIBLE destruction, then the cracks simply went further into the heat under the pressure of the water column (already melted water inside) and destroyed the pipes. And the pressure of the water column is not a big deal
