Royalist range

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.
