Hoval’s UK-manufactured 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 to 27
bar and 12MW). Net
efficiencies are up to 92% with
efficient thermal insulation to reduce
standing losses to, typically, 0.3%.

The Royalist is a conventional
three-pass wet back, steel shell boiler
which 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 also available
using the Hoval
Thermocondensor or
bespoke economisers.

The boilers are supplied
with sophisticated controls
to optimise performance, and are
operated on a stand-alone basis or
interfaced to a BMS.
