The best coolants for heating systems for 2024

People who live in country and private houses 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 a rating of the best heat carriers for heating systems for 2024.

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 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 the charts. The average cost is glycerin - a gentle and harmless substance, but with its own minus. We'll have to replace the usual Teflon gaskets. Propylene glycol stands out from expensive bases. Its advantages are its 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, see if it is moderate or cold.

The boiling point indicates when the substance will begin to foam. The later it boils, the longer it will flow and transfer heat. The maximum indicator is 115 C.

Please note that some products can be diluted with water, while others should only be used in 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 the specified period that the product has a gentle effect on the metal and fully complies with its characteristics.

Rating of the best heat carriers for heating systems for 2024

Warm House Eco-30

Buyers believe that the domestic heat carrier Warm House Eco -30 has proven itself well. It is a 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. The circulation is also improving.

Conclusion

In order for the heating system to work for a long time and regularly, delighting you and your household with warm walls and the absence of cold weather, you need to take care of a selection of high-quality coolant in advance. To avoid mistakes when choosing, it will not be superfluous to read reviews of verified buyers. Of course, you can not be puzzled by the purchase of antifreeze and use the most ordinary water, but here the saying "a miser pays twice" can play an unpleasant role. The fact is that when water freezes, it 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 service life of the heating system is sharply reduced. Therefore, it is much more profitable to read the rating of the best heat carriers for heating systems for 2024 and choose the most suitable one for you. The competent use of the functionality of antifreeze will provide you with the desired warmth and help to keep your property safe and sound.
