DESCRIPTION OF PELLET BOILER FROM SERIES BISOLID
The steel made hot water pellet boiler from series Bisolid is designated for heating of local
installations with natural or forced water circulation performed with or without circulations
pump. The heat exchanger unit is module of the system designated for automatic utilization
of pellets and for heating of the circulations water. The cleaning of the ash from the burning
process can be performed manually through the combustion chamber’s lower front door, by
taking out the ash-tray and gathering its content in proper for the purpose containers. The
combustion process organization and the heat exchanging with the boiler body internal
surfaces ensures high efficiency. The operation of the system: hot water pellet boiler from
series Bisolid and automated pellet burner with manually cleaning from series Bisolid GP
xx_B hc> depend on the chimney draught. The chimney draught depends on the chimney
condition and on the flue gas temperature.
The hot water boiler’s Bisolid heat exchanger construction complies with the resistance
requirements for such type of appliances: EN 303-5:2012 - "Heating boilers. Part 5: Heating
boilers for solid fuels, manually and automatically stoked, nominal heat output of up to 500
kW. Terminology, requirements, testing and marking.

The boiler consists of the following components/modules:
The main module of the hot water boiler is the boiler body (heat exchanger), as the
automated burner from series Bisolid GP xx_B hc> is mounted on its side. The heat
exchanger is offered in two versions: so called “left” and “right” mounting. The
automated pellet burner with manually mechanically cleaning can be mounted only on
the left or only on the right side of the boiler body.
The heat exchanger unit construction is made of steel plates. The combustion
chamber is designed in the front lower part of the heat exchanger, as the ash
container is below it. The heat exchanger is with compact size related to the achieved
heating output, because it has three pass design, which provides optimal heat
exchanging and high efficiency.
