WebJan 25, 2024 · 3. Underfloor mixing temperature set to 60C !! The UFH design will usually specify the design flow temperature to be in the 40C to 50C range. 4. Check the primary flow and return pipework orientation at the UFH manifold is correct, and that the UFH pump is in the correct way around. 5. WebJan 18, 2014 · Just keep in mind that when flows merge, so do temperatures. Even though we are bringing back 56°F warm water from our system, the return water will mix with the 500 gpm of 44°F in the common pipe, so that the final return water temperature to the chillers is 53°F (temperature mixing formula). This gives us a Delta T of 9 degrees on …
