The best heat transfer fluids for heating systems for 2022

People who live in suburban and private homes know firsthand how important it is to protect pipes from freezing water. To avoid problems with pipes in the heating system, it is important to install a high-quality coolant. Our article will demonstrate the ranking of the best coolants for heating systems for 2022.

How to choose

A heat carrier is a liquid or gaseous substance used to transfer thermal energy. When buying antifreeze, pay attention to the following selection criteria: base, crystallization point, boiling point, the possibility of dilution with water and the time that the antifreeze will last.

The basis can be read on the packaging, studying the composition.Ethylene glycol is considered the most frost-resistant component, but it is also the most controversial in terms of benefits, because toxicity is off scale. The average cost is glycerin - a gentle and harmless substance, but with its own minus. You will have to replace the usual gaskets with Teflon ones. Of the expensive bases, propylene glycol stands out. Its advantages are resistance to overheating and chemical neutrality.

The crystallization point indicator can vary from -15 to -65 degrees, so when buying, you need to focus on the climate of the region, look at whether it is moderate or cold.

The boiling point tells you when the substance begins to foam. The later boiling occurs, the longer the fluidity and heat transfer will be. The maximum is considered to be 115 C.

Please note that some products can be diluted with water, while others must be used exclusively in their pure form. The most beneficial is, of course, the one that can be diluted with water.

Service life is also an important parameter, since it is during this period that the product has a gentle effect on the metal and fully corresponds to its characteristics.

Rating of the best coolants for heating systems for 2022

Warm House Eco-30

Buyers believe that the domestic coolant Warm House Eco-30 has proven itself well. It is propylene glycol antifreeze. The product is available in two weight categories: 10 kg and 20 kg. The packaging is equipped with convenient handles for easy transportation. To create a mixture of the desired temperature, the required amount of the product is diluted with water. Dilution with water makes it possible to reduce the viscosity of the product and increase the heat capacity. Circulation is also improved.The service life of the product is 5 years, but we must remember that a lot depends on the operating conditions. If you bring the substance to a boil, then the thermal decomposition of propylene glycol and additives will begin. Buyers believe that if the pipes are made of plastic, and the heat exchanger in the boiler is copper, then the service life is doubled.

You can buy from 1000 rubles.

Conclusion

In order for the heating system to work for a long time and properly, delighting you and your household with warm walls and the absence of cold weather, you need to take care in advance of selecting a high-quality coolant. To avoid mistakes when choosing, it will not be superfluous to read the reviews of verified buyers. Of course, you can not be puzzled by the purchase of antifreezes and use the most ordinary water, but the saying “the miser pays twice” can play an unpleasant role here. The fact is that when freezing, water tends to increase in volume, which, accordingly, leads to rupture of pipes. Also, it is water that contributes to the appearance of corrosion and the formation of scale, which means that the life of the heating system is sharply reduced. Therefore, it is much more profitable to read the rating of the best heat transfer fluids for heating systems for 2022 and choose the most suitable one for you.Proper use of the antifreeze functionality will provide you with the desired warmth and help keep your property safe and sound.
