In preliminary projects, there are usually already supply ideas or even individual variants. In a first step, this rough variant can be calculated and mapped using rules of thumb, for example. Double-clicking on the heat generator opens the catalog for the respective heat generator. By scrolling to the right or expanding the window, all parameters of the respective heat generator can be viewed in the catalog.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In our example of the apartment building, there are two heat generators: the air-water heat pump and the solar thermal collectors. By double-clicking on the respective component, you can configure its parameters as shown below.
