The heating fluid contains an antifreeze and biocide that also protects against corrosion, but it’s this quality that depletes over time. Alde Protective Premium Antifreeze is magenta in colour and should be replaced every 5 years. If your fluid is a different colour, change it as soon as practicable.

Antifreeze – more than just frost protection
You may already be aware that Alde Heating is a hydronic systems. This means that a heating fluid is heated up in the boiler and then circulated through pipework, which provides heat via emitters like convectors, towel radiators, etc.
Purpose of antifreeze:
- To transfer heat from the boiler, preventing cavitation, boiling and foaming.
- Frost protection.
- Corrosion protection.
- Bacterial protection.
- Lubricates the circulation pump.
What type of antifreeze should I choose?
- Only use Alde-approved antifreeze products.
- Concentrated antifreeze should be mixed 50:50 with deionised water, but most products these days are pre-mixed/ready to use.
By maintaining your heating fluid, you know that your system contains the right mix of antifreeze and water. That the risk of frost and corrosion damage and bacterial growth has been minimised.
Equip your Alde Heating system with the best conditions for stable and pleasant heating.
