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.
