Boilers connected
in cascade enables the heating of bigger buildings. Boilers
should be of the same output. Such a system gives better possibilities
of heat source dynamics than a system with only one boiler.
Particularly in “transition period” (springtime
or autumn) boilers may be serviced alternately. Boilers with
such a connection enables for its utilization with the output
close to nominal, which warrants boiler longer durability.
Heat accumulation tanks allows for boilers
better adjustment according to actual weather conditions.
In transition period (the spring, autumn) any boiler without
heat accumulation set is switched on and off very often. If
the set is connected, the boiler works constantly and the
energy is lost into the vessels. Each boiler switching on
and off means fuel losses. It may be avoided if the heat accumulation
set is used.
Simultaneously, in the transition period
(the lowest temperature in winter time) the accumulation set
helps to reheat the whole central heating system.
Also it should be mentioned that few heat
sources such as solar collector, heating pump, or similar
may be connected to the heat accumulation set.
