Royalist range

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.
