Boiler connected in cascade enables heating of bigger buildings. Boilers should be of
the same output. Such system gives better possibilities of heat source dynamics than
system with one boiler only. Particularly in .transition period. (springtime or autumn)
boilers may be serviced alternately. Boilers with such connection enables for its
exploitation with the output close to nominal, what 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 cumulated 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 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.Boiler connected in
