HVAC Installation: Heat Pumps, Underfloor Heating, and Radiant Panels

This tender is for an HVAC installation project in Hamburg-Ohlsdorf, Germany. The core of the work involves the supply and installation of heat pump systems, totaling 295kW of capacity. This includes four air-water heat pumps (200kW total) and one water-water heat pump (95kW). The project also necessitates the installation of approximately 1,200 meters of industrial steel piping and 1,500 square meters of underfloor heating. A fresh water station with a capacity of 180 liters per minute and a 5,000-liter buffer tank is also required.

Furthermore, the project includes the installation of various radiant ceiling systems: 250 square meters of radiant heating ceiling integrated as a plasterboard (GK) ceiling, 210 square meters of hybrid ceiling sails, and 105 square meters of radiant ceiling panels. The mix of different heat pump types and the integration of various heating surface technologies (underfloor, radiant ceilings, etc.) suggest a moderately complex project, potentially requiring careful coordination between different trades and specialized expertise in integrating these systems. The deadline for submissions is April 17, 2026.

Given the lack of published value, interested contractors should carefully evaluate the bill of quantities (if available) and assess their capacity to handle a project of this scale and complexity within the given timeframe. The combination of different heating technologies suggests a need for strong project management skills.
