No, this will affect the operation of the underfloor heating. Since it is ethylene glycol and has a high flash point, it can be dangerous when heated. If no one is at home for a short period of time, it is best to set the boiler temperature to the lowest setting and run it at a low temperature to avoid freezing. If no one is at home for a long time, all water from the underfloor heating system should be drained.
What is antifreeze for underfloor heating?
Antifreeze can harm the human body
Gas wall-underfloor heating system with mounted boiler Adding antifreeze is a common measure to prevent pipes from freezing and cracking during cold seasons. However, if used incorrectly, it can present certain dangers.
For example: glycol antifreeze can be toxic to humans and is unlikely tot be irritating and corrosive if inhaled or in contact with skin.
The correct anti-freeze measures should be as follows: when there is no one at home for a short time (within a week), the boiler temperature can be set to the lowest. At this time, the boiler will enter the antifreeze state of low temperature operation. Underfloor heating requires only water. I haven't heard of refilling antifreeze. Compared to water, the main difference between antifreeze and water is that it is. It's antifreeze. Anti-rust and anti-limescale are just a relief.
