The company was founded by Cecil Duckworth in 1962 as Worcester Engineering Co Ltd, based at the Old Vinegar works in Worcester. Worcester's early success is attributed to the pioneering of combination boilers in the UK, [3] further successful performance in the UK heating market led to the expansion and relocation of the factory to its current headquarters in Warndon in 1990.
Combination boilers are popular in Europe where market share in some countries is in excess of 70%, with a projected rise in the United Kingdom to 78% by 2020. [3] This trend is attributed in part by a social trend towards more numerous but smaller households and an ever-increasing trend towards physically smaller and often high density housing.
Vanderbilt boiler An American design, similar to the Lentz and large launch-type boilers. [36] Velox boiler: [61] vertical boiler: flued or fire-tube designs where the main shell is a cylinder on a vertical axis, rather than horizontal. Boilers of this external form may have a great variety of internal arrangements.
A condensing boiler Hot water central heating unit, using wood as fuel. A central heating system provides warmth to a number of spaces within a building from one main source of heat. A central heating system has a furnace that converts fuel or electricity to heat through processes.
A common arrangement where hot-water space heating is employed is for a boiler also to heat potable water, providing a continuous supply of hot water without extra equipment. Appliances that can supply both space-heating and domestic hot water are called combination (or combi) boilers. Though on-demand heaters provide a continuous supply of ...
In 1989 the Metal Box company demergered, and MB group formed; Caradon was acquired by MB group becoming MB Caradon in 1989 and the Hull boiler factory became Caradon Ideal in 1993. [24] In the 2010s the Ideal Boilers' foundry was closed with the loss of 57 jobs and outsource casting to third parties. [28] [29]
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
Working principle of a combined cycle power plant (Legend: 1-Electric generators, 2-Steam turbine, 3-Condenser, 4-Pump, 5-Boiler/heat exchanger, 6-Gas turbine) The efficiency of a heat engine, the fraction of input heat energy that can be converted to useful work, is limited by the temperature difference between the heat entering the engine and ...
