Why this split
San Franciscan SF-25 leads on the weighted score for most boutiques we modelled.
Probat stays competitive when production volume outweighs the price gap.
Deep dives
IR radiant heat transfer
Diedrich IR drums radiate through a double-wall — different first-crack timing than convection.
Operators switching from Probat or Giesen need 15–20 calibration batches, not a copied profile.
- Log development time ratio across 3 charge weights
- Compare ground colour at same end temp
What to verify with your dealer
Neither OEM publishes binding street prices — quotes move with queue and freight.
Verify with vendor
- • Confirm San Franciscan SF-25 lead time and freight to your dock
- • Confirm Probat P25 III install kit and probe package included
