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 remains switched off, making natural cooling an energy efficient and affordable way to cool interiors.
The compact NC-Box is fitted at the factory with all necessary components and can be rapidly installed by your heating contractor.
Unlike traditional heating appliances, heat pumps utilise renewable energy from the ground, sun, groundwater or air. They lower consumption of fossil fuels, conserve valuable resources and reduce CO2 emissions that damage the environment.
