  • the invention relates to a domestic hot water generation system.
  • heating and air conditioning systems In residential construction, especially in multi-story low-energy residential buildings, very high costs are currently and even more so in the future due to work to prepare heating and air conditioning systems. This includes the complex installation of piping systems for air, heating, and hot water. Heating and domestic hot water are prepared separately by a central heating system and then pumped separately to the consumers.
  • the costs for structural engineering, such as plumbing and heat supply amount to approximately 7.5% of the construction costs for new buildings, and can sometimes reach up to 12.5% when using controlled living space ventilation.
  • the costs of building extensions will continue to rise in the future due to the use of new, more environmentally friendly technologies, as the installation of piping is resource-intensive.
  • the owner or builder of a new building is required to purchase various services and products from different suppliers. These include, for example, a heat generator, water heater, heat distribution system (e.g., radiators or underfloor heating), optional cooling, individual room control, water heater, heating circuit manifold, heat meter, and the installation of these components.
  • a heat generator e.g., water heater, heat distribution system (e.g., radiators or underfloor heating), optional cooling, individual room control, water heater, heating circuit manifold, heat meter, and the installation of these components.
  • TTA hot water heat pump For example, a so-called “TTA hot water heat pump” from tecalor is already available. This includes a hot water boiler or hot water storage tank whose drinking water can be heated using a small heat pump. For this purpose, ambient air is drawn in, and its thermal energy is used by a heat exchanger to heat the stored drinking water or hot water.
