11 best system coolants heating

Review of the best according to the editors. About the selection criteria. The the material is subjective, is not advertising and is not serves as a guide to the purchase. Before purchase is needed consultation with a specialist.

In autonomous heating systems, water circulates through pipes, transferring heat from the boiler to the radiators. It is cheap and effective, but requires regular supervision. If the house is visited in winter periodically or there are long trips on vacation, the system may scatter. In the case of boilers requiring electrical connections provoke freezing of pipes and rupture of batteries capable of long power outages. To prevent it is used coolants with alcohol or oil, designed for heating systems of private houses and industrial facilities. They work the same way as antifreeze in cars, and do not freeze when negative temperatures. From the rating and reviews below you will find out the best products in this category, which will help determine a choice.

How to choose a coolant

Heat carrier rating for open and closed heating systems contains goods that prevent pipe thawing; and preventing scale formation, bacterial growth and corrosion metal compounds. But choosing antifreeze for the boiler and radiators it is important to pay attention to some parameters substances:

  1. The basis. The package always indicates which product is the main part. The most non-freezing is ethylene glycol. It has increased fluidity, so the joint sealing should be especially thorough. But with him there are never any problems in circulation plan. But this coolant is the most toxic. Middle at a price and a relatively new type – glycerin, more sparing and harmless, but requiring the replacement of conventional gaskets with Teflon. The most expensive is propylene glycol, which is chemically neutral and resistant to overheating. Separate substance low anti-freeze oil but allowing you to heat it to higher temperatures.
  2. Crystallization point. This is the number of degrees below zero, after which the fluidity is lost. The indicator varies from -15 to -65 degrees, which is important to consider when choosing a coolant for operation in heating systems in various regions with cold and temperate climate.
  3. Boiling point. Indicates when antifreeze begins foam. For some, this comes after 70 degrees. The maximum indicator is 115º C. The later when overheating the liquid boils, the longer it retains its fluidity, the effectiveness of additives and will continue to perform the main functions – transfer heat.
  4. Possibility of dilution with water. Some substances for heating systems can only be used in pure form, while others allowed to dilute with ordinary water according to the table of the ratio of parts, depending on the winter temperature in the region. Second option more economically advantageous because it allows you to fill the volume of the system less antifreeze and add the rest for free water.
  5. Life time. On each heat carrier is indicated safe lifetime guaranteed by the manufacturer. During of this period, the tool will gently act on the seals and metal, as well as meet the specified characteristics for crystallization and boiling. Some liquids last for 4-5 years, others up to 10, which affects heating maintenance costs.
