Around 40 percent of the primary energy consumption in Germany and Europe falls into the building sector. The complexity of building technology and the high demand for different forms of energy such as steam, heat, power and cooling create an enormous energy input. A high level of supply reliability and functional capability must always be provided, while at the same time the immense cost pressure demands an efficient supply of energy. Thanks to individual energy concepts from Bosch, consisting of innovative boiler technology and other important systems such as combined heat and power units and solar thermal plants, it is possible to achieve permanent cost savings. At the same time, these systems not only operate reliably, but also reduce the need for supervision and keep maintenance work low.
