The AGA cooker is a heat storage stove and hot plates.
It was built in 1929 by Swedish Nobel prize winner for physics, Dr. Gustaf Dalén ( 1869-1937 ) developed, who was employed as a senior engineer at the Swedish Aktiebolaget Gas Accumulator (AGA ). In 2009 the flock by former British licensee of the AGA, the Aga Rangemaster Group are sold under Aga - Rayburn, which produces its own words, 2,000 stoves per year, which enjoy particularly in English country houses some popularity.
The stove is based on a heavy, traditional cast iron construction. Starting from a heat storage technology a central heat source with two large hotplates and two ovens is combined into one unit. The hotplates are divided into a high and a heatable boilerplate that can be used as a griddle. Heavy, hinged insulating covers for this duration heated plates are considered to be characteristic of AGA cookers.
The idea of different overheating repeated in the ovens. The basic equipment includes a roasting oven and a Simmering Oven. With the larger herds oven and a reheating furnace will be added. The herd are continuously fired, the individual cooking areas have no control. At most, a regulation exists, which allows a "vacation reduction" or shutdown.
In the original construction, the heat source was fired with coal. The offer in Germany, modern Aga ovens can be electrically heated with either gas or. In the international offering are also found with coal or fuel oil powered burner.
In the 21st century, the AGA cooker is considered as energy wasters. The manufacturer specifies a constant power of 0.86 kW. Thus, its energy consumption is 7,500 kWh per year and at current prices in April 2009 to over 1,200 € / year operating costs.
1912, the year of his Nobel Prize, Dalén was seriously injured in an explosion during a test program at AGA and lost his eyesight. While recovering, he spent much time at home and learned so, how much effort had to operate his wife for cooking. Although blind, he felt challenged to develop a stove that allowed all the essential cooking techniques to easily and was also suitable for heating.
The construction of the hearth was Dalens hobby, took place in the little free time. In 1929 the stove on the market and provided with an energy consumption of only eight pounds of coal within 24 hours, given its cooking and heating capacities then a sensation of view and made him - especially in England - popular rapidly.
In the 1970s, the AGA -structured and re- focused on the gas business. The rest, and thus the production of the oven was off.
In the 1970s, the emerging central heating displaced the hitherto conventional oven heating. This means that the AGA stoves were considered as increasingly anachronistic, both in concept and in design and energy consumption. The business with them was correspondingly decreased. Since especially got a living in traditional country houses, conservative clientele in England, took over the local licensee the entire production and worldwide distribution.
In the 21st century, the oven enjoyed thanks to its perceived as a " retro", exclusive designs, its heavy construction and its cooking properties and depending on the location and type of the house again increasing also because of the heating concept, popularity, particularly in 2009.
