Coolant or water?
Which coolant is better to use in heating systems of country houses, cottages and industrial premises?Universal coolant or water?
You can answer these questions yourself after reading this article.
We will describe the advantages and disadvantages of each of these materials and the features of their application.
It is known that the installation of a heating system must be carried out by competent plumbers with a special education who are familiar with the requirements of these rules SN 478-80 and strictly comply with them. This is a guarantee of high-quality and long-term operation of the heating system.
But as often happens, to save money or for some other reason, people hire “imposter” plumbers who don’t even know What is SNIP. And then, when the moment of hydrostatic tests comes up (well, at least they are done), leaks are detected, the system is not completely warmed up. And the search for reasons begins: poor coolant, poor-quality threads, etc., but let’s not talk about sad things.
Water is a good coolant with the highest thermal conductivity. However, systems with two-inch pipes, cast-iron batteries with the so-called “self-flowing” circulation are a thing of the past. There were no filter elements. Also, with such a pipe diameter, no one thought about some kind of dirt inside the system and about deposits. The fuel was relatively cheap and the main task was to warm up the system well. But now it is not economical.
Modern heating systems are more economical and versatile. In one system, both a solid fuel boiler and an electric boiler or a gas boiler can be connected. And the distribution of the coolant can be simultaneously carried out to the radiators and the underfloor heating system. These heating systems operate under pressure, which is provided by the pump. Installation of such systems should only be carried out by professionals.
A linen strand impregnated with red lead or white mixed with drying oil should be used as a sealant for threaded connections. Moreover, in high-temperature systems, an asbestos strand is used along with linen impregnated with graphite mixed with drying oil.
Modern heating systems have smaller pipe diameters, distribution blocks, and filters. And no matter what you fill your system with, be it coolant or water, MANDATORY it is necessary to flush the system from dust that is in pipes and various fittings after production and storage. From slag and scale and from conservation oil compositions, which should be used to treat components in boilers and distribution blocks.
UNWANTED use of water in the heating system described above. This is due to the fact that oxidation processes will necessarily occur. After all, we have a solid fuel boiler made of steel or cast iron, a gas boiler or an electric boiler will definitely have copper elements, and our modern aesthetic aluminum batteries. Everything corrodes with water. Moreover, the presence of such different metal elements in one system will necessarily lead to the formation of galvanic processes. In simple terms, the corrosion of metals will accelerate.
Well, the biggest drawback of water is its freezing temperature. No one is immune from power or gas outages. And if it’s a country house that is visited only on weekends to escape from the bustle of the city. Also uneconomical heat industrial premises on weekends or holidays. Water freezes already from 0 degrees. As a result, expanding, it breaks pipes and radiators. Thus, disabling the heating system for a long time, not to mention subsequent financial costs.
All this can be avoided by using low temperature coolant. It also has a drawback – it costs money.
Non-freezing coolant for heating systems has high fluidity, so special attention should be paid installation of the system and the preparation (flushing) described above before filling. After all, it is impossible to drain it like water and fill it with another, you will have to make a purchase again. When installing the system, in order to exclude leaks, heat-resistant silicone and a special Teflon thread are used. Do not be stingy and require plumbers to use materials designed to work with the coolant.
We must not forget about the pump that supplies the coolant through the system, its capacity should be 30% more than the calculated one. Heat transfer fluids have a higher density and viscosity than water.
Where can I buy heat transfer fluid for heating?
High-quality heat transfer fluids manufactured by AO KHIMPROM (Kharkiv) are designed for any heating systems. They are used in systems with solid fuel boilers, gas and electric. Quality assurance.
Heat media are used in systems of private houses, food enterprises, as well as in chiller and boiler systems. Thanks to many years of experience, technologies with the use of food anti-corrosion additives have been developed.
The coolant is safe to use, non-toxic to humans and animals. The warranty period for this coolant is 5 years, but after this period it should not be disposed of. The manufacturer, if necessary, will test it and give recommendations for adjusting the composition. Do not mix with heat transfer fluids from other manufacturers.
The coolant is not combustible. It is recommended to store in a place protected from the sun at positive temperatures.
The choice is yours, Good luck.
