The new high efficiency Ensbury LT steel boiler range from Hamworthy Heating, features an innovative low temperature management system that enables return water temperature to reach as low as 15°C without condensing and, with no minimum flow rate, provides versatility in systems applications.
In addition to the usual choice of fuels - natural gas, LPG (propane), or oil of 28- and 32-second viscosity, the Ensbury LT boilers are suitable for liquid biofuel, which provides sustainable energy solutions using FAME (fatty acid methyl ester) or RME (rape methyl ester) biofuel blends up to B50.

The Ensbury LT boiler range comprises 14 models with outputs from 70kW to 580kW, for use with fully modulating or high/low matched burners, delivering operating efficiencies up to 95% net (86 part gross) at part load.

'This innovative low temperature management system puts Ensbury LT boilers head and shoulders above any of its competitors,' says Richard Walker, sales and marketing director at Hamworthy Heating.

Ensbury LT boilers from Hamworthy feature a three-pass heat exchanger which has been designed to reduce the level of NOx. With a range of low NOx matched burners, the boilers achieve up to European Class 5 performance.

'The low temperature management does not require electronic controls and is achieved through the mechanical design, which simplifies the solution and ensures a long and reliable performance,' comments Walker.

'The thermal mass within the Ensbury boiler can accommodate fluctuating operating conditions and, with no minimum water flow requirement, eliminates the need for a shunt pump, simplifying the hydraulic system design. A high level of insulation also ensures very low standing losses at just 0.15 - 0.5%.'

As with all Hamworthy boilers and related plant, the Ensbury LT range is supported by the company's extensive technical expertise, which has been built up over many years. Full support is available from the design stage through to commissioning and after-sales care with tailored warranty packages.
