Antifreeze for heating — is a special liquid used in heating systems to prevent the coolant from freezing during the cold season. Unlike ordinary water, antifreeze has a significantly lower freezing point, which allows heating system work effectively even at sub-zero temperatures.
Antifreeze for heating: main characteristics and features
- Compound: Antifreeze is usually made on the basis of ethylene glycol or propylene glycol with the addition of corrosion inhibitors, stabilizers and other chemical additives. These components protect the metal parts of the system from corrosion and increase the service life of the equipment.
- Temperature range: Antifreeze retains its properties at very low temperatures, usually from -20°C to -60°C, depending on the concentration. This makes it indispensable in regions with a harsh climate.
- Compatibility: Antifreeze must be compatible with the materials from which the heating system elements are made (steel, copper, aluminum, plastic). Incorrect selection of antifreeze can lead to equipment damage and leaks.
- Safety: Ethylene glycol-based antifreezes are toxic and require careful handling, while propylene glycol-based antifreezes are considered safer to use, especially in residential areas.
- Service life: Antifreeze needs to be replaced periodically as its chemical properties deteriorate over time. The recommended replacement period is usually 3-5 years.
Antifreeze for heating is especially important for country houses, cottages and other facilities where the heating system does not work constantly or where long heating outages are possible. The use of antifreeze prevents freezing of pipes and equipment, and also minimizes the risk of accidents and damage to the system in the winter.
