Hot glycol and deionised water mix circulates around the system through radiators and pipes by means of a pump. The convectors that are placed along the outer walls heat the air. This then rises and heats the walls and furniture. Since hot air rises, an air barrier is formed in front of the windows, which keeps the chill off.
The Coolant/Glycol G13 is an ethylene glycol/glycerine based extended life antifreeze/coolant that combines the fast healing aluminum protection associated with silicate additives with the extended cooling system protection.
The mix of glycol and deionised water is 50-50 and only approved gycol by Alde should be used.
