ALDE ANTIFREEZE

In one of your cupboards or wardrobes you will see a plastic container containing pink fluid with a minimum level and maximum level indicated on the side. This is antifreeze and requires to be topped up.

The fluid that is found in an Alde Central Heating System is actually an Ethylene Glycol based antifreeze and coolant. It is the same antifreeze and coolant you would find in any automotive engine or radiator system. Ethylene Glycol Antifreeze is a mixture of Ethylene Glycol and de-ionised water. It is often made up of corrosion inhibitor, virucides and coloured dyes. So, what does this liquid do? Ethylene Glycol Antifreeze has a number of functions within the heating system. Primarily, as the name suggests it’s an antifreeze, giving you frost protection down to -36 degrees Celsius when it is mixed 50:50 with water, but it has a number of other things it does. It is also a corrosion inhibitor which protects all the hot surfaces within the heating system. It’s a virucide which prevents bacterial growth within the system and it acts as a coolant, which helps to give you a nicely balanced heating system.

Alde recommend that you do not mix antifreeze types and there are a number of different types available on the market.
