More from this brandAll Bunn coffee machinesOverview
Bunn's CWTF15-3 is a 120V commercial drip brewer that plumbs directly into a water line, brewing a 12-cup pot in about 4 minutes and up to 3.9 gallons per hour, with 3 lower warmers for holding multiple pots.
It's built for an office or small breakroom rather than a home counter, low enough to sit under a cabinet and connected straight to plumbing instead of a reservoir you fill. It does not ship with carafes or a funnel, buyers who expect a complete home setup out of the box should budget for those separately.
- Brews a 12-cup pot in about 4 minutes, up to 3.9 gallons per hour
- Direct plumb-in with included water line
- 3 lower warmers for holding multiple pots
- SplashGard funnel and stainless steel construction
Who it's for
Right for offices and breakrooms replacing a rented or aging commercial brewer who already have or will buy their own carafes. Not the pick for someone wanting a self-contained home drip machine with decanters included.
Pros and cons
- Brews quickly and consistently per owners
- Straightforward to plumb in as a replacement
- Low profile fits under kitchen cabinets
- Three lower warmers hold multiple pots
- Carafes and funnel not included
- One report of a disconnected indicator light
- One report of a failed water shutoff sensor
Performance notes
The SplashGard funnel keeps hot liquid away from hands while pouring, and the brewer's rated output of 3.9 gallons per hour held up for at least one office swap. One reviewer disconnected a 30-year-old Bunn and had this one plumbed in and brewing in under 30 minutes. A separate report of a failed water shutoff sensor flooding a break room floor is worth noting as a known failure mode.
