3.1. OVERALL CHARACTERISTICS OF HOT WATER BOILER
FROM BISOLID COMFORT SERIES
The solid fuel boilers from BiSolid Comfort 03/04/05 series are designed for heating of
domestic and industrial buildings.
Preconditions for proper functioning of the hot water boiler are not only its professional
installation, but also the needed chimney draught and its correct operation.
The solid fuel hot water boiler from Bisolid Comfort series is designated for heating systems
which are suitable for systems with forced water circulations.
The hot water boilers from series BiSolid Comfort are offered in three output models (defined
by the number of sections: 3, 4 and 5) with heating capacity from 18 to 32 kW.
The cast-iron boiler body consists of sections and serves as combustion chamber (including
for flue gas extraction) and in the same time as water heat-exchanger. There are three types
of sections - integrated front and rear and from 1 to 3 middle sections (same type), which are
between them. The boiler body required size is built during the assembly (combustion
chamber and water heat-exchanger), with a suitable number of sections. The assembled
boiler body is equipped with the necessary pipe elements for connecting to the water-supply
system.
The boiler body is also equipped with brackets for installation of thermostat sensors and
brackets on the legs for fixing the boiler to a floor base. Steel plate covers are mounted on the
boiler body and are filled inside with heat-isolation.
In order to guarantee the boiler’s proper operation and that it will operate economically, it is
important to know that its nominal heating output is equal to the heat losses of the heated
premises.
Choosing a boiler with insufficient heating output will lead to unadequate heating of the
premises and by such terms not providing of the heating comfort.
Choosing a boiler with unnecessarily high heating output will lead to terms in which the boiler
will not operate at its full ouput power and as consequences to excesive condensation and tar
deposits.
3.2. SAFETY AND CONTROL DEVICES
The hot water solid fuel boilers from series BiSolid Comfort 03/04/05 are equipped with two
main control components:
Chimney (flue) flap.
Thermo-regulating valve (TRV).
The chimney flap (Figure 3) is element which supports the chimney draught regulation, i.e.
exctracting the flue gasses to the chimney. The flap is situated in the boiler’s flue back side
and is controlled manually.
