3. DESCRIPTION OF THE APPLIANCE
Bio-max Plus steel water heating boilers intended for use with wood pellet powered
burners are among the most modern solution heating appliances fired with ecological
renewable fuels. They are an excellent source of heat for the heating of houses, workshops
and other low–capacity structures, fulfilling the demands of users who demand that modern
boilers require only minimum service and maintenance (the appliances are fully automated)
while ensuring a high level of comfort and low operating costs. The design of the boiler is
based on a system of smoke tubes and reversal chambers (triple–pass design), which
ensures high combustion efficiency of the appliance and minimises chimney stack loss. The
exchanger and combustion chamber are made from high–grade, certified steel sheet. The
front of the boiler is fitted with a closing three–way diaphragm, which is used both for
installing the burner and cleaning the combustion chamber. In the rear of the boiler is a steel
smoke conduit which is used to connect the boiler to the flue gas duct, while in the upper part
is a large and easily accessible washout hole, which facilitates cleaning of the heat
exchanger and the smoke tubes. A tray for ash is located in the bottom part of the boiler. Ash
generated during the combustion process fall directly onto the tray, from which they can be
easily and rapidly removed. Furthermore, all boilers are fitted as standard with a fuel storage
bin, which can be attached either to the left or the right side of the appliance. The boilers are
intended for usage in a closed system, and are additionally provided with a cooling coil pipe
for the water block and a SYR 3065 or HONEYWELL TS131 thermal protection device.
Another distinguishing feature of the Bio-max Plus boiler is the very low content of dusts and
toxic compounds in flue gases – considerably below the values permitted for the group of
solid–fuel fired boilers – which ensures that they are fully ecological.
Every boiler in the standard configuration is a single–function heating appliance, however if it
is connected to a hot domestic water heat exchanger (for example the LUMO WCW), it can
also be used for the provision of hot domestic water.
