Efficient insulation

Hoval's 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 up to 92% with highly efficient thermal insulation to reduce standing losses to, typically, just 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.
