Andy and Eric discuss their recent project installing a Viessmann air-to-water heat pump system, exploring its performance, efficiency, and potential applications in radiant cooling and heating. They share insights on system design, energy savings, and practical considerations for HVAC professionals.
Takeaways

The Viessmann system can operate quietly and efficiently in residential settings.
Proper piping size and layout are critical for system performance.
Monitoring power consumption helps optimize system operation.
Wide delta T in radiant cooling shrinks as the system reaches steady state.
Condensation risk can be managed by controlling dew point and set points.
