This accessory is used when the heat pump is installed in a room with low ceiling height or when for some other reason you want to share the heat pump. After dividing, the lower part of the heat pump becomes 1500 (S735) mm high.(Height, upper part: 674 mm).
The NIBE DEW S42 is a complete docking kit that allows installers to connect the S735 exhaust air heat pump to the VPB S200 hot water cylinder. Supplied with a dedicated AXC control module, diverter valve, shut-off valve, check valve and a full set of immersion sensors, the DEW S42 provides all the hydraulic and electrical components necessary for reliable hot water integration. With pre-configured wiring looms, labelled connectors and factory-mounted communication cabling, the DEW S42 ensures a straightforward, standards-compliant installation.
The OEK S20 enables NIBE S735 and S735C exhaust air heat pumps to increase usable heating capacity by intelligently mixing outdoor air with the home’s exhaust air stream. By introducing outdoor air through a dedicated duct fitted with a motorised damper and an ambient temperature sensor, the main unit can adapt ventilation behaviour based on outdoor conditions, switching seamlessly between mixed air and exhaust only operation to protect performance and system safety.
The SAM S42 is a dedicated supply air module designed to expand the capabilities of the NIBE S735 and S735C exhaust air heat pumps by adding tempered supply air ventilation. The unit incorporates a water to air coil, buffer vessel and dedicated circulation pump to preheat outdoor air before it enters the dwelling, improving comfort. Installation is straightforward, with wall or cabinet mounting options and clear pipework and ducting provisions, including separate connections for outdoor air and supply air.
The TOC 40 top cabinets provide a practical and visually clean way to conceal ventilation ducting and services above NIBE indoor units. Designed to match the width and depth of a wide range of products, they create a seamless, built-in appearance while maintaining the required 3 mm clearance from the main front panel for correct operation. Installers can select from fixed-height versions of 245 mm or 345 mm for standard ducting runs, or choose the 385–635 mm adjustable model when additional height is needed.

NIBE PV is an integrated solution which is based on a fully modular system with several basic sizes: 4 / 8 / 12 / 16 / 20 kW. Each basic package has nominal power of 4 kW and consists of 10 panels, mounting parts and an inverter with communication module, all of which are ready for installation. The solar package can easily be expanded with additional solar panels for optimum use of roof space.
NIBE PV comprises of monocrystalline silicon cell panels which use PERC technology, with an output of 400 Wp. The solar panels are elegant, all-black panels. NIBE PV harnesses sunlight all year round and converts it into electricity. NIBE PV can be connected to your NIBE heat pump* for maximum energy efficiency.
Thanks to smart technology, the product gives you control over your energy consumption and will be a key part of your connected home. The efficient control system automatically adjusts the indoor climate for maximum comfort, and you do nature a favour at the same time. * applies to systems which can be connected to NIBE Uplink and myUplink.

HTS 40 is an accessory that records humidity and temperature.
The NIBE RMU S40 is a room unit with 2,8” touch display with built in temperature and humidity sensors. It is used to control and monitor your NIBE S series heat pump/indoor module from another room in the house than the room where the heat pump is placed.
The NIBE S Series is a natural part of your connected home. Smart technology adjusts the indoor climate automatically while you’re in complete control from your phone or tablet. Giving maximum comfort and minimum energy consumption, while doing nature a favour at the same time.
The NIBE ECS 41 kit allows installers to add one or more additional heating circuits to a NIBE heat pump installation where different supply temperatures are required, such as radiator and underfloor heating combinations. Each kit includes a dedicated AXC accessory module, shunt valve, shunt motor, circulation pump and temperature sensor, enabling the new zone to run as a fully controlled climate system with independent flow temperature, heating curve and pump operation. The ECS 41 is sized for larger UFH areas above 80 m².
ECS 40 is used when heat pump is installed in houses with up to four different climate systems that require different flow line temperatures, for example, in cases where the house has both a radiator system and an under floor heating system.
