Because these urns are so thermally efficient (holding heat for 6 hours) they don't require a flame.
Deluxe, heirloom-quality coffee urns are breathtaking centerpieces in-and-of themselves. These jumbo coffee urns are made of stainless steel inside and out, and feature foam insulation that will keep contents hot for as long as 6 hours.
For best results, pre-heat urn with hot water prior to using. Lid will lock into place for best heat retention. Thermal efficiency will vary because of content level, whether you "top off" the contents, and whether lid is kept secure.
These deluxe coffee urns are available in three sizes:
1.5 Gallon Urn is 22.5" tall, 12.5" in diameter, and 14" wide. 3 Gallon Urn is 25.5" tall, 14" in diameter, and 15.5" wide. 5 Gallon Urn is 28.5" tall, 16" in diameter, and 17" wide.
Hand wash urns. To clean the outside, wipe with a damp cloth to clean, and with a dry cloth to polish.
