- Small commercial buildings
- Villa and residential complex projects
- Domestic hot water
Boran is designed for regions with long, cold winters. Its territory is wherever the winter design temperature is below −15 °C: Central Anatolia, the inland Black Sea region and the high parts of Eastern Marmara. Its design point is A −25 / W 65: it produces 65 °C water and holds its capacity even when the outdoor air drops to −25 °C. This comes from the vapour injection (EVI) compressor circuit, the economiser and the İYB control working together.
In buildings with radiators
65 °C leaving water makes it possible to replace a boiler with a heat pump without changing the existing radiator system. That is why Boran is also the right series in Marmara for renovation projects that keep the radiator circuit. In new buildings with underfloor heating it runs at a lower water temperature and more efficiently. For a project with a mild winter and no radiators to supply, the Poyraz series remains the more economical choice.
Selection
The three capacities (12, 14 and 16 kW) belong to the same casing family. In cold regions, choose the capacity from the heat loss at the design outdoor temperature; what counts are the values at −25 °C, not those at +7 °C. Heat loss depends on the building's insulation, the orientation of its façades and how it is used. Share the calculation or the consumption of the existing boiler, and we will choose the model together.
What connects to the system?
Boran, too, covers heating, cooling and domestic hot water from the same unit. It works with the wall-hung HİD / HİT, HİDRA with its tank or HİDREM with direct-expansion cooling as the indoor unit; underfloor heating, radiator and fan coil circuits are all supplied from a single system. Hot water comes from the indoor unit's tank or from an external cylinder. The compressor is DC inverter and the fan BLDC; remote monitoring and solar energy integration can be added.
