The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function.
Will underfloor heating pipes freeze if you don't use antifreeze?
There is no special formula of underfloor heating antifreeze on the market, because usually if you don't turn on the underfloor heating in winter, you have to blow water, otherwise it will cause freezing and cracking.
It is recommended to consult a professional here. Inferior automotive antifreeze can easily cause explosions. So never do the work yourself.
The underfloor heating pipe is filled with antifreeze and will generally not freeze if not in useilized.
The freezing point of antifreeze is below the lowest local temperature in winter. Therefore, when the antifreeze in the floor heating system is below the freezing point, the water in the floor heating pipe. will not freeze and therefore no frost damage will occur.
In addition, if the floor heating system is not used for a long time, it is recommended to drain the water in the floor heating pipes to avoid problems such as scale if the underfloor heating system is to be used. turned off for a long time, it is recommended to close the return valve of the main heating pipe and drain all the water to prevent the pipes from freezing and cracking.
