The captured official documents do not print an efficiency column for both sizes, so the comparison rests on capacity and the printed mechanical data. The ClearFire-V 10 HP is rated 345 lb/hr steam from and at 212°F against the ClearFire-V 9.5 HP's 328 lb/hr. The 9.5 HP and 10 HP are adjacent ratings of the same package: 65 sq ft of heating surface and a 335 W blower on both, with a 17 lb/hr steam step between them.
Water and pressure data are printed in the family document. Pressure rating: 150 psig design; 60 psig minimum operating on the smaller unit against 150 psig design; 60 psig minimum operating on the larger.
Both models are documented in the same official Cleaver-Brooks material, so the choice is a load and plant-layout decision: size to the calculated demand, then verify connections, venting and weight in the family document for the exact model.
