For the new factory complex of the Bata Works in Zruč nad Sázavou, it was necessary to ensure heat supply. Therefore, as early as the end of 1939, the construction of the so-called small boiler house, located behind the first production building, was underway. It was a ground floor building with a modest floor plan and brick construction. However, its capacity would not be sufficient to heat the other buildings, so in October 1940 the construction of a new boiler house was started. It was located next to the first production building and was already of iron construction with brick lining.
The three central segments of the new boiler house were almost 18 m high, while the right side segment was lower at approximately 13.5 m. In the first phase, concrete foundations were laid and an iron structure erected on which the coal-fired steam boilers and all the necessary technological equipment were placed. The walls were then bricked up. A metal chimney was erected on the flat roof, which reached a height of 15 m. The facade of solid masonry was dominated by tall windows running across the upper half of the building. The boiler room was also equipped with a washbasin and shower for the staff. The central heating plant was completed in 1941 and by 1948 the left side segment was added. The metal chimney was replaced in the late 1960s and early 1970s by a detached brick chimney, which became an imaginary symbol of Sázavan.
As the construction of the new Zruč continued during the socialist era, more and more buildings were connected to the boiler house. In 1999, the central heating plant was purchased by the town as part of a tender procedure and in 2003, a reconstruction was carried out during which the old boilers from the Bata era were replaced with a new biomass boiler. The brick chimney was also lowered, but no other significant changes were made. Therefore, the central heating plant retains its original form and function to this day.
