A modular, tempered-glass warming surface built for buffets and holiday tables, with eight heat settings and a 24-hour timer, usable as one panel or up to four side by side. The pitch is flexibility and even heat for a crowd. The tension is that a warming tray tops out well below cooking heat, one buyer found it didn't get hot enough for larger pans, and the manual leaves the choice of temperature to trial and error.
Four separate glass panels are both the strength and the limit of the BTUVC HNB22X4. You can run one panel for a weeknight dinner or all four for a 35"x15" buffet, each at its own temperature. But a warming tray holds food rather than reheating it, and with a 248°F ceiling it works best with dishes that go on hot, in pans sized to the panels.
NoFussDeal rates the BTUVC 4-in-1 Warming Tray 4.2 out of 5 at $62.99, compared against 4 alternatives sold on Amazon. Last updated September 27, 2026.
Up to 4 panels combine into a 35"L x 15"W surface, which BTUVC sizes for 6 to 8 dishes. Run them singly for a family meal or all together for a buffet; one buyer found the set fits a full-size chafing tray and prefers it to chafing racks and Sterno burners indoors.
An NTC temperature sensor regulates 8 settings from 108°F to 248°F, which BTUVC says gives fast, even heat without cold spots. Separate panels can hold separate temperatures, handy when delicate sides and heartier mains share a table. The manual has no recommended-temperature guide, so expect some trial and error: low settings suit bread and delicate dishes, the top settings suit dense mains that went on hot.
A built-in timer runs for up to 24 hours and supports scheduled start and delayed shutdown, so the tray can be warm before guests arrive and switch itself off afterwards. A child lock stops kids or pets changing the settings by accident.
The black tempered-glass top with gold edges is sold as shatter-resistant, waterproof and oil-resistant, and works with ceramic, glass and plastic tableware. Spills wipe off the flat glass easily, and the shipping box has a carry handle and repacks neatly, which is a sensible way to store glass panels between parties. At 10.6 pounds the set is heavy enough to need two hands.

The tray is praised for holding food at serving temperature for several hours, and its size suits parties, family gatherings and holiday dinners. It looks smarter and feels sturdier than a silicone warming mat, the glass wipes clean easily, and being able to set a different temperature on each panel helps when delicate and hearty dishes share the table. The weak points: the manual gives no temperature guide, and one buyer found it neither hot enough nor large enough for big pans.

Set the panels on a flat, stable table that can take the 10.6-pound set, with the cords clear of where guests will walk.
Use 1 to 4 panels to size the warming surface to your buffet or dinner.
Connect the 120-volt plug and choose one of the 8 temperature settings between 108°F and 248°F, then let the glass warm up before the food goes on.
Use the 24-hour timer to schedule a delayed start or automatic shutdown for longer events.
Long enough for a full buffet: it holds food at serving temperature for several hours, and the timer runs for up to 24 hours.
No. The instruction booklet has no recommended-temperature chart, so finding the right setting for each dish takes some experimenting.
Yes, a built-in child lock is designed to prevent accidental operation by kids or pets.
The tempered glass is sold as shatter-resistant, waterproof and oil-resistant, and it feels sturdier than a silicone warming mat. It is covered by a 2-year manufacturer warranty.
The BTUVC HNB22X4 combines a large modular glass surface, 8 temperature settings and a 24-hour timer in one set built for hosting as well as everyday meals. It warms up quickly, holds food at serving temperature for hours and wipes clean. The gaps are real, though: there is no temperature guide in the manual, and the panels can struggle with large pans.
For hosts who want a scalable, glass-topped warming surface with a temperature and timer for each panel, the BTUVC tray delivers on most fronts. Cooks with oversized pans, or anyone who wants a temperature chart out of the box, may be better served elsewhere.
