For buildings that have restricted exterior access, or for architecture where additional exterior equipment installation is not recommended, or simply for energy-efficient buildings that are going "Green", City Multi offers heating and cooling solutions through our water source systems. By tapping into the building's existing water loop or by utilizing geothermal energy, highly efficient year-round heat transfer keeps every area on every floor at optimum comfort levels.

The compact size of each City Multi's water source system makes it easy to fit in an elevator and a machine room. Individual systems can be interconnected for more efficient floor-to-floor double heat recovery, ultimately reducing your energy costs.
