When there is no one at home for a short time (within a week), the boiler temperature can be set to the lowest setting. At this time, the boiler will enter the antifreeze state of low temperature operation. a certain corrosive capacity, which will significantly reduce the life of the boiler and the system. It should be noted that before this operation, please fully consider other internal pipelines, such as confirming that the water pipe will never freeze
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 floor heating system from corrosion and scale, thereby prolonging thelifespan of the system. Therefore, the model with underfloor heating and HR-617 antifreeze is better.
