Shown on fig. 2 (and,heating systems concern so-called deadlock systems in which circulating rings are not equal on length, and the shortest ring passes through a strut nearest to a copper, and the longest - through a strut most remote from a copper.

1 - a copper; 2 - the main strut; 3 - a broad tank; 4 - an alarm line; 5 - a submitting line; 6 - an air collector; 7 - submitting struts; 8 - return struts; 9 - a return line; 10 - the pump; 11 - a broad pipe

- with the bottom distributing: 1 - a copper; 2 - a submitting line; 3 - a return line; 4 - submitting struts; 5 - return struts; 6 - an air-line; 7 - an air collector; 8 - a broad tank; 9 - the pump; 10 - a broad pipe.
On fig. 8 the system of heating of other type where length of all rings same and, hence, resistance of rings (is identical at identical thermal loading of struts) is represented.
Such systems name systems with passing movement of water , and them usually establish only in systems with pump circulation. All struts and heating devices are in these systems almost on an equal footing that considerably facilitates adjustment . The lack of systems with passing movement of water consists that for their device is required bolshee quantity of pipes, than for deadlock systems.
