With the onset of cold weather, the issue of reliable operation of the heating system becomes a priority, especially for owners of private homes. And one of the main threats to it is the risk of freezing of the coolant during an emergency shutdown of the boiler or electricity. An ice plug can rupture pipes and radiators, resulting in expensive repairs. It is to prevent such situations that antifreeze is used.
However, replacing water with a special non–freezing liquid is not as simple a solution as it might seem at first glance. Antifreeze has its own characteristics that must be taken into account when designing and operating a heating system. Making the wrong choice or application can do more harm than good.
Water or antifreeze: when you really need it
First, it's worth understanding if you need antifreeze at all. If you live in a house all the time and the heating system is stable, then in most cases regular water is enough. Water is the best heat carrier in terms of its physical properties, it has a high heat capacity and low viscosity.
Antifreeze is justified in the following situations:
- A house with periodic accommodation: cottages, country houses where the heating is turned on only on weekends. In this case, the risk of defrosting the system in your absence is very high.
- Regions with harsh winters and frequent power outages: if turning off the lights for several hours can cause the system to freeze, antifreeze is insurance.
- Systems with outdoor elements: for example, if part of the pipeline runs through an unheated attic or basement.
In other cases, the use of antifreeze may unnecessarily complicate and increase the cost of the system.
Types of antifreeze: propylene glycol versus ethylene glycol
There are mainly two types of antifreeze for heating systems on the market, which differ in their basis.
Based on ethylene glycol. This is the most common and cheapest option. It is effective and protects well against corrosion (if there are special additives). But it has one huge disadvantage – it is very toxic. Even a small amount ingested can lead to severe poisoning. Therefore, it should absolutely not be used in double-circuit boilers, where there is a theoretical possibility of mixing the coolant with hot water for domestic use.
Based on propylene glycol. This option is much more expensive, but it is considered environmentally safe and non-toxic (propylene glycol is used even in the food and cosmetics industry). It is recommended for use in residential buildings, especially where there are small children and animals. It also has good anti-corrosion properties.
Nuances of use: what you need to remember
Replacing water with antifreeze requires consideration of several important points. Firstly, antifreeze has a lower heat capacity and a higher viscosity than water. This means that to transfer the same amount of heat, you will need a more powerful circulation pump (about 10-15% more powerful) and radiators with a larger area (also 10-15% larger).
Secondly, antifreeze is more fluid. It is able to seep through the slightest leaks in the joints that were sealed for water. Therefore, all joints and seals in the system must be in perfect condition. Only special antifreeze-resistant pads can be used. And thirdly, any antifreeze has a service life (usually about 5 years), after which it loses its properties, and it needs to be completely changed.
Safety above all
Using antifreeze is an effective way to protect the heating system from defrosting. But this decision requires a balanced approach and strict adherence to all rules.
Everyone makes a choice between toxic but cheap ethylene glycol and safe but expensive propylene glycol based on their own conditions and budget. However, in an apartment building, saving on security is a dubious undertaking. Properly selected and filled with antifreeze will give you peace of mind for the whole winter.
