The prompt

# PROJECT TOPIC Design the heating installation that will serve a **basement + ground floor + 4-storey building (B+GF+4)**, as well as the boiler plant that will provide the heating medium for space heating and domestic hot water preparation. Domestic hot water will be stored in a **bivalent hot water storage tank**. The building will be heated using **steel panel radiators**, while the pipes used for the distribution system, risers, and connections to the heating units will be made of **copper**. The boiler plant will operate on **solid fuel**. A complete system of **solar thermal collectors** will also be designed to provide supplementary thermal energy for domestic hot water preparation. A **decentralized heat recovery ventilation system** will be installed. The building is located in the locality of: **Sibiu**. The possibility of supplying thermal energy using the following equipment will also be analyzed: **Case 1 –** A boiler plant operating on **natural gas**. **Case 2 –** A **ground-source heat pump (water-to-water)**. For Case 2, the heating of the indoor spaces will be provided by an **underfloor heating system**. The installation shall be designed in accordance with the technical requirements of: - **SR 1907** - **Normative I13** for the design and execution of central heating installations. - **Installation Manual – Heating Installations (I)**.
