DOYMAfix® Connect HP Flex
Maximum flexibility for heat pump connections
Custom-designed connection systems for air-to-water heat pumps—flexible, secure, and easy to install.
With DOYMAfix® Connect HP Flex , the connection between the monoblock heat pump and the building can be made quickly, cleanly, and with a precise fit for the specific installation situation. The pre-assembled system allows for custom pipe lengths, reduces installation effort on-site, and ensures a secure, gas- and watertight passage through exterior walls in contact with the ground or floor slabs.
Ideal for new construction and retrofits—designed for maximum installation flexibility.
Your Benefits at a Glance
Every installation is different. That’s why DOYMAfix® Connect HP Flex is tailored to the required connection length. This saves time, reduces waste, and simplifies planning.
Maximum flexibility: The integrated stainless steel corrugated pipes can be installed with a small bend radius. Changes in direction can be achieved without additional fittings.
Quick installation: The system is designed for exceptionally easy installation. The pre-assembled components allow for quick installation with minimal tools—even by a single person.
Reliable building sealing: When combined with the appropriate DOYMA sealing systems, the result is a permanently gas-, water-, and radon-tight penetration tailored to the respective application areas.
Neat Wiring: Pipingcarrying media , as well as power and control cables, are routed separately from one another. This ensures a clear layout and simplifies installation.
Developed for modern heat pump systems: DOYMAfix® Connect HP Flex was specifically developed for air-to-water heat pumps in a monoblock design. The system combines maximum design flexibility with professional building penetration and supports an efficient construction process from the shell of the building through to commissioning. Thanks to the custom manufacturing of connection lengths, the system can be optimally adapted to local conditions—regardless of whether the heat pump is installed directly on the building or at a greater distance.
Technical Highlights:
- Custom-configurable connection lengths
- Flexible stainless steel corrugated pipes (DN32 or DN40)
- Insulated supply and return lines
- Separate cable protection conduits
- Flexible outer pipe DN200
- Gas- and watertight
- Radon-proof
- Suitable for new construction and existing buildings
- Suitable for exterior walls in contact with the ground and floor slabs
- Typical Applications
New construction: Pipe routing and building penetrations can be optimally preparedas early as the construction phase.
Renovation: Ideal for retrofitting heat pumps with custom piping routes.
Custom installation scenarios: When standard lengths are insufficient or special routing is required, DOYMAfix® Connect HP Flex provides the necessary flexibility.
