Water-Source Heat Pump Selection Questions

Which projects suit a water-source heat pump chiller?

Commercial buildings, institutions and industrial projects with a suitable water loop or available heat source can use a water-source system for hydronic heating and cooling.

Can it support a boiler upgrade?

Yes. High-temperature hot-water operation can support building heating upgrades. Match the water-source conditions and heating temperatures to the existing distribution system.

What should I send for initial selection?

Share the project location, heating or cooling load and the available water-source temperatures. EXINDA can help identify the configuration and technical package for the next design stage.
