The Advantages of Hydronic Systems versus Variable Refrigerant Flow (VRF) – A Critical Analysis
This new whitepaper presents a review of technical literature plus post-installation analysis of three types of HVAC systems: Variable Refrigerant Flow (VRF), Hydronics and Hydronics integrated with Armstrong Design Envelope technology. The paper points out the differences between the system types and reveals that cost-savings claims made by VRF manufacturers are not supported by the data. Hydronic systems are less expensive than VRF systems, and Hydronic systems that use Design Envelope technology are far less expensive.
