Connection to the heating system
The many of heat consumer's boiler houses connection diagrams are becoming
increasingly complexes. There are connected a few of alternative heat generators - the
solid fuel or gas boiler, extra pellet burner, electric heating system, thermal pumps,
solar collectors and etc. For the premises heating there are used a several of radiators,
heating floor or air heating, there are mounted the accumulation tanks, various
equipment of the water preparation.
Therefore the proper setting of the boiler and formation of the boiler connection
diagram according to the customer requirements is allowed only for the qualified
engineers and experienced installers. The
picture 4
is showing only the part of the
recommended boiler's connection to the heating system diagram, which ensures the
return water temperature not lower than 60°. Diagram not contained the auxiliary
technological equipment (valves, expansion vessel and other).
Picture 4.
The part of recommended boiler installation diagram, performing which, ensures the long
service life of the boiler, not allows to form the condensate. There are not shown the auxiliary
technological equipment of the boiler house (expansion vessel, valves and other).
Requirements for the connection:
•
The valves, disconnecting the boiler from heating system installed in the system
tubes, must be fully opened. In order to avoid accident through negligence, take off
the grips of the valves after having opened them;
•
In order to avoid the condensate formation, which can significantly reduce service
life of the boiler, there should be installed the such heating system, which enables
maintaining the return water temperature of no less than 60
C;
•
It is necessary into the heating system, as much closer to boiler, to install the
protective valve (G½B), preventing the boiler housing against to pressure bigger
than 1,5 bar (0,15 MPa). In between the boiler and protective valve there is not
allowed to install any shut-off fittings
;
Notice. If the system pipes contained the shut-off valves, which disconnects boiler
from the heating system, they should be fully opened. In order to avoid any
accidents caused by inattention, it is expedient to take away the valves grips,
having the valves fully opened.
