AGA cooker

The AGA cooker is a heat storage stove and cooker, which works on the principle that a heavy frame made from cast iron components can absorb heat from a relatively low-intensity but continuously-burning source, and the accumulated heat can then be used when needed for cooking. Originally heated by slow-burning coal, the Aga cooker was invented in 1922 by the Nobel Prize-winning Swedish physicist Gustaf Dalén (1869–1937), who was employed first as the chief engineer of the Swedish AGA company (Swedish: Aktiebolaget Svenska Gasaccumulator, English: Joint stock company Swedish Gas Accumulator). The cookers were first imported to Britain in 1929, and were first manufactured there under license in the early 1930s. The cast iron components were first cast at the Coalbrookdale foundry in the 1940s, where they are still made today by the Aga Rangemaster Group.
