Boiler connection kit 073989

Complete hydraulic kit for heat pump integration

This boiler connection kit (ref. 073989) is a ready-to-use solution that simplifies the integration of a traditional heat source with a modern heat pump in a split system. Instead of selecting individual hydraulic and control components separately, you receive a complete module containing a three-way valve, necessary pipe connections, and connection connectors. This enables faster installation of the boiler as a backup heat source with a reduced risk of assembly errors.

The kit is specifically designed for Atlantic Alfea heat pumps and other compatible units, ensuring full electrical and hydraulic compatibility. The package includes not only the valves but also insulated flexible pipes and an outlet temperature sensor, eliminating the need to purchase additional accessories. For the installer, this translates into time savings on-site – simply connect the ready-made circuit to the existing central heating system and boiler.

Key structural features and application

The product is intended for indoor installation, occupying relatively little space thanks to its compact dimensions: width 318 mm, height 162 mm, and depth 333 mm. This compact housing allows the kit to be installed even in limited technical spaces, such as in a distribution cabinet or directly next to the boiler.

Several key features of this system are worth noting:

• The kit comes with a pre-installed three-way valve controlled by an actuator, ensuring smooth switching of the heat source between the heat pump and the boiler without the need for additional valve assembly.
• Complete connection provisions include connectors and insulated flexible pipes, significantly simplifying connection to the boiler and the entire heating system.
• The included water outlet temperature sensor allows the control system to accurately monitor the operation of the heating circuit, eliminating the need to purchase additional sensors.
• Designed for indoor installation, the environmental conditions are stable and do not require additional protection against atmospheric factors during device operation.

Application in hybrid systems

This solution is crucial for building efficient hybrid systems, where the heat pump operates as the primary energy source, and the boiler (gas or oil) activates only during periods of high heat demand or heat pump failure. The three-way valve included in the kit is responsible for directing the flow of heating water – when the temperature drops below a set threshold or the pump cannot meet the demand, the system automatically switches to operation with the boiler.

Thanks to the presence of connection connectors and insulated pipes, the risk of heat loss at the transition point between devices is minimized immediately after installation. There is no need for additional insulation of short pipe sections between the kit and the boiler or heat pump. This is a plug-and-play solution for plumbers seeking a proven method for connecting two different heat sources without the need to design their own water distribution circuit.
