1917 - The first evaporation meter
As far back as 1917, the first heat cost allocators in the world was assembled in Denmark. The meters were based on thermoelectric measurement princip introduced through the company Kemp & Lauritzen. These meters were serviced by Brunata until 2014.


1935 - Mass production of heat cost allocators
By 1920 a German magazine published an article about a heat cost allocator, where consumption was recorded as evaporation from a liquid-filled ampoule, mounted on the radiator. The Danish engineer Constantin Brun saw the opportunity to share the costs of heating in an accurate and fair way using this meter. In 1935 he founded the engineering firm Constantin Brun in order to develope this measuring method. In 1939 the company was formed as a limited company (A/S) and linked with the production of heat cost allocators to radiators and the development of heat metering systems for central heating systems.
