Why Rheia?

Homebuilders needed a cost-effective solution to meet the new energy codes by moving ducts and equipment into the home’s conditioned space.

Traditional HVAC can’t do that, but Rheia can.

How It Works.

Static Pressure

Central Returns

The Rheia system utilizes a supply manifold, ducts, fittings, and diffusers that operate as a system at typical static pressures (~.4 in. wc). This ensures no change to equipment design and operation.

Using a central return system improves static pressure management creating a better performing HVAC system. Jump ducts and passthrough ducts ensure correct return static pressure when sized correctly.

Room CFMs

Balancing

Room airflows are accurately predicted to design requirements while maintaining static pressure limits. Rheia provides better missing of air flow from multiple micro-diffusers in each room, eliminating hot or cold spots.

Rheia ducts terminate in supply boots, each with adjustable dampers for accurate balancing. In addition, the Rheia Verify app makes it easy to balance the entire home resulting in consistent room-to-room temperatures.
