Hoval’s upgraded version of its STU
range of UK-made wood
pellet boiler is of ‘plug
and play’ skid mounted
configuration with fully
wired and factory tested
PLC based
FlameTronix touch
screen control.

Hoval says the control
system ensures optimal wood pellet
combustion resulting in ‘best in class’
efficiencies of 92% as well as ‘best in
class’ particulate emissions.

Independent tests confirmed the
boiler achieved less than 5 mg/MJ
particulate emission without any
additional particulate
abatement system.

The control system is
web-linked for remote
monitoring and is
designed with ease-ofuse
in mind. There is
great emphasis on
ease of installation and easy
commissioning.
