Overview

This Adcraft SU30 is a 30-cup commercial hot water urn in dual-insulated stainless steel, with a dripless spout, dry-boil protection, and an adjustable temperature control for continuous hot water service.

The listing title references a 100 cup WB-100 model, but the attributes, description, and model number all point to the 30-cup SU30 urn, so the smaller capacity is what buyers should expect. Reviewers who have run several units for over a year at work praised the adjustable temperature and heavy build, though at least one buyer found the unit boiled water away rather than holding it warm and suspected a missing lid seal.

  • 30-cup dual-insulated stainless urn
  • Dripless 2-way spout
  • Dry-boil protection, auto temp control
  • Encapsulated heating elements

Who it's for

Offices, break rooms, and small food service settings that need continuous hot water in stainless commercial-grade housing. Not for anyone specifically wanting the larger 100-cup capacity implied by the listing title, since the actual specs describe a 30-cup unit.

What buyers say

From Amazon customer reviews.

Two reviewers who have used multiple units at work for over a year praised the heavy-duty build and accurate adjustable temperature, saying it gets hotter than other boilers they had owned. Two other reviewers had problems: one received the unit without its cover, and another said it boiled the water away within an hour or two rather than keeping it warm, suspecting a missing seal between the lid and pot.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Adjustable temperature holds close to setting
  • Heavy-duty stainless construction
  • Dripless spout, dry-boil protection
What to check first
  • Listing title capacity conflicts with actual 30-cup specs
  • One unit arrived without a lid/cover
  • At least one report of poor heat retention

Performance notes

Dual-insulated stainless construction is meant to cut energy use by about a third while keeping water hot from first cup to last, and reviewers who ran the urn daily for over a year said the adjustable dial holds within about 5 degrees of the set temperature. One reviewer's unit instead boiled its water away within an hour or two and did not hold warmth, which they attributed to a possible missing seal between lid and pot.
