NIBE DEH 41 Docking Kit

Description

NIBE DEH 41 is an advanced accessory designed to enable smooth and controlled docking between compatible NIBE heat pumps and external heat sources. This control unit makes it possible to operate the system with, for example, an existing oil boiler, electric boiler, wood boiler or pellet system for energy-efficient and reliable heating comfort all year round.

Optimized energy control and prioritization

By integrating the additional heat directly via the heat pump's control center, energy use is automatically optimized. The system ensures that the heat pump is prioritized first, while the external heat source is connected when needed to meet higher power requirements during cold periods or for the production of domestic hot water.

Key features and benefits

• Intelligent system integration: Enables the connection of the heat pump and existing boiler for a flexible hybrid system.
• Optimized energy efficiency: The heat pump's intelligent control regulates when external additional heat is started, which minimizes unnecessary energy consumption.
• High operational reliability: Creates a stable system with redundancy where the external heat source assists with high power outputs and cold outdoor temperatures.
• Compact enclosure: Delivered in a durable junction box with multiple cable entries for smooth and protected electrical installation.
• Safe temperature control: Included sensors and relay solutions provide reliable monitoring of flows and boiler temperatures.

Compatibility and areas of application

NIBE DEH 41 is designed to dock heat pumps from the NIBE F series (such as F1145, F1245, F1155, F1255 and compatible air-to-water systems such as VVM indoor modules) to:

• Oil-fired and gas-fired boilers with automatic shunt
