Viessmann NC-Box for natural cooling

NC-Box –– let your heat pump provide cooling in the summer

Energy efficient and affordable cooling

On hot summer days, the heat pump control unit switches to natural cooling via the NC-Box and removes excess heat from the interior via the heating circuit into the cooler ground or groundwater. This requires only a small amount of electricity for the circulation pumps. All other functions of the heat pump remain switched off.

This makes natural cooling an energy saving and inexpensive way to cool a building.

All in one box

The compact NC-Box is fitted at the factory with all necessary components and can be rapidly installed by your heating contractor.
