[TRNSYS-users] Heating Coil: Type 670-1 bug

[David Bradley]

Fred,
 I think you might be confusing efficiency and effectiveness. 
Effectiveness is actual energy transfer divided by maximum theoretically 
possible energy transfer. The air and water side heat transfers need to 
be equal or else there is an energy imbalance across the coil.
Best,
 David
