Hoval’s UK-made Royalist range of
hot water boilers is available in
standard BS EN14394 versions (13
models up to 10 bar and 10MW)
and the Royalist-H BS EN12953 high
temperature model (13 models up to
27 bar and 12MW). Net efficiencies
are to 92% with efficient thermal
insulation to reduce standing losses
to, typically, 0.3%.

The conventional three-pass wet
back, steel shell boiler, due to its
generous boiler water content,
requires no minimum water flow
rate. It is suitable for firing with a
range of matched burners, for use
with gas (including bio-gas), oil
(including bio-diesel) or dual fuel.

Condensing versions are available
using the Hoval Thermocondensor
or bespoke economisers.

All units have sophisticated
controls to optimise performance,
operating on a stand-alone basis or
interfaced to a building management
system. Hoval’s TopTronic controls
are also available for higher levels of
control functionality.
