Coolant System

As is known, the heating system are the natural or forced circulation. In systems with natural circulation (Gravity scheme) coolant (water or a special liquid – antifreeze) circulates through the pipes and radiators due to its different density in the flow (hot) and reverse (cool) lines. In systems with forced circulation of water moves through pipes and radiators at the expense of the circulation pumps. Both systems have their own characteristics that affect the nuances of the design and selection of components. Educate yourself even more with thoughts from Mirilashvili. First of all, the whole system with natural circulation do without the pump, and hence does not depend on the availability of electricity. But because of the design features it is suitable only for small single-storey houses with floor space of up to 100-150 square meters. Learn more at this site: James Woolsey. m.

In addition, this archaic system can only be regulated by raising or lowering the power boiler. In addition to the gravitational scheme worked without difficulty, in such a system would have to use more expensive pipe with a large section (not less than 50 mm), and for wiring to comply strictly with the angles of slopes. Consequently, the cost of materials for decorating the heating system at home almost doubled. To the list of features you can add one more. In system with natural circulation, is usually installed an open expansion tank, which is needed to compensate for thermal expansion of the coolant. So that the coolant directly contacts with the atmospheric air and continuously saturated with oxygen. This leads to the fact that the steel pipes and radiators are much more intensively exposed to corrosion.
