Natural gas, oil, biofuel or dual fuel burners High/low or modulation burners Low NOx burners Flue gas economiser (se e page 46) Options: Largest output high efficiency steel shell power flame boiler. The Melbury HE has sufficient thermal mass to absorb residual combustion heat meaning it is not necessary to maintain a flow rate through the boiler. This allows for a more flexible design of the heating system and eliminates the need for primary circuit pumps or boiler shunt pumps, so reducing energy consumption. Back end temperature protection is required. NO MINIMUM FLOW ARNE ECONOMISER Increase the system efficiency by combining the Melbury HE with the Arne flue gas economiser. Use with single & multiple boiler applications. See page 46 f or more information.
