Taco HS2 Software   

The HSS Design Suite is a free collection of tools that takes the "time-consuming" out of hydronic system design. In fact, an entire LoadMatch® system can be designed within 30 minutes from top to bottom. At the heart of the Design Suite is Taco Hydronic System Solutions®. With HS2 you can design and compare HVAC systems, eliminate recalculation time for changes, calculate plant total loads and flows, size pipe and equipment, select and schedule equipment, and make design changes quickly and easily, all while reducing errors.
