Antifreeze model HR-617 is better. HR-617 antifreeze has good heat conduction properties and can quickly transfer heat from the floor heating system to the room, thereby improving heating efficiency. HR-617 antifreeze also has good protective properties and can protect pipes and equipment of the underfloor heating system from corrosion and scale, thereby extending the service life of the system. Therefore, the model with underfloor heating and HR-617 antifreeze is better.
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 setting. The boiler will enter low temperature and antifreeze operation mode. Underfloor heating only contains water. I haven't heard of it. Antifreeze Filling The main difference between antifreeze and water isthat anti-rust and anti-limescale are only a relief. p>
