Application area 

 

The installation consisted of one of the boiler systems manufactured by Munktell, and moulded element modules were connected to it via a steam pipe system which could be "stacked" to the desired size (see photo above). The installation, which in part transported hot water heated by the steam boiler, but mainly hot steam, was supplemented over time with steam flange pipes and was insulated over certain sections. The application area was primarily for large public buildings and the armed forces. 

 

History 

 

One of the first installations was at Swedish Royal Opera House in Stockholm, which led to one of the period's world-famous singers, Jenny Lind, complaining of cold floors amongst other things. At almost the same time Munktell received an order to install steam heating for the casemates (concrete room for artillery pieces and staffing) at Vaxholm fortress. This was then followed by an order for steam heating installations for prisons. At first only for women's prisons, followed later by the male prisons, but only for cell type prisons. Both Munktell's in Eskilstuna and Bolinder's in Stockholm started their production of steam heating installations in the mid-1800s. This was the central heating of the 1850s. What we today call central heating only came into being during the last decades of the 19th century.
