Exhaust Air Module NIBE S135 Heat Pump Water Heater

Maximize your energy savings and significantly improve your home's ventilation profile with the NIBE S135. 

This intelligent and highly efficient exhaust air module functions as a specialized heat pump water heater and is specifically developed to dock directly with NIBE's smart indoor modules for air/water heat pumps, such as the VVM S320 and VVM S325. Combining these setups delivers a complete, low-energy system that manages space heating, domestic hot water, and mechanical extraction ventilation simultaneously.

High-efficiency heat recovery and parallel operation
The NIBE S135 effectively ventilates your property by extracting stale, warm indoor air from utility zones and wet rooms. Instead of letting this thermal energy escape, the module traps the heat and transfers it smoothly back into your water-borne space heating system or domestic hot water circuit. Home heating and tap water production occur fully in parallel alongside your docked air/water heat pump, securing an optimized seasonal coefficient of performance (SCOP). Furthermore, in cooling-enabled installations, the system can generate hot water and refreshing comfort cooling at the same time.

An integral component of your connected smart home
As the NIBE S135 is designed as a dedicated system accessory, all advanced settings and automation parameters are handled directly via the docked indoor module's color touchscreen interface. The module integrates seamlessly into NIBE’s cutting-edge S-series network. This layout ensures it utilizes the indoor unit's built-in Wi-Fi connectivity, support for wireless sensors, and advanced cloud routines like Smart Price Adaption (hourly grid-price tracking) and automated weather compensation. You always maintain full remote transparency over your ventilation and indoor climate straight from your smartphone via the myUplink app.

Compact layout with high extract capacity
The exhaust air module operates with ultra-low noise levels and offers a high ventilation flow rate, allowing it to comfortably satisfy building ventilation regulations in most standard family properties. Thanks to its sleek, compact layout (605x600x490 mm), it mounts easily to the wall directly above the indoor module or onto a separate wall bracket, saving valuable floor footprint inside your utility room or mechanical space.
