Difference between Heatwheel and Energy wheel

Question

Accepted Answer

Heatwheel and Energy wheel are both types of energy recovery ventilation systems used in HVAC systems, but they differ in their specific mechanisms and applications.

Heatwheel uses a rotating wheel with a desiccant coating to transfer heat and moisture between incoming and outgoing air streams, while Energy wheel uses a rotating wheel with a matrix of heat-absorbing material to transfer heat only.
Heatwheel is more effective in transferring both heat and moisture, making it suitable for humid climates, while Energy wheel is more efficient in transferring heat only, making it ideal for dry climates.
Heatwheel may require additional maintenance due to the desiccant coating, while Energy wheel may have lower maintenance requirements.
Examples: Heatwheel - Munters Airxchange, Energy wheel - Enthalpy wheel from Greenheck
