Evenheat · Electric Kiln · GTS Studio Series Evenheat Glass Kiln - GTS 28 Model EH-GTS-28 · 240V · 28″ L × 28″ W × 13.5″ D · 1800°F The GTS 28 is Evenheat's perfect larger studio kiln — the same fiber-and-firebrick hybrid construction as the GTS 24, scaled up to 5.8 cubic feet for bigger panels, more pieces per load, and busier studios. Firebrick walls and floor help manage the anneal while the fiber lid keeps heat-up efficient, giving you a durable, energy-conscious kiln for daily studio use.

Key features
Fiber Lid + Firebrick Walls & FloorA hybrid build: a lightweight fiber lid heats fast and cuts weight, while firebrick walls and floor store and gradually release heat for smoother, more even annealing.
Swing View Adjustable Control EnclosureThe control panel swings to your preferred angle for easy reading and operation, then tucks safely out of the way when not in use.
Power Interrupt SwitchElements shut off automatically the moment the lid is raised, adding a critical layer of safety during loading and unloading.
Relay Access PortBuilt-in access port lets a technician service or replace the relay without removing the full control panel, cutting downtime and service cost.
Two-Position Lid VentAdjustable venting accelerates cooling and helps release adhesive fumes and moisture during the early stages of a firing.
Firebrick Wall & Floor Heat StorageFirebrick walls and floor gradually release stored heat during the cooling cycle, helping produce smoother, more even annealing than an all-fiber chamber.
Optional accessories
Quiet Drive Solid State RelayEvenheat's patented relay with zero moving parts fires 60 times per second for ultra-tight temperature control. Never needs replacement and extends element life.
Extra Kiln ShelvesAdditional shelves and posts allow for multi-level stacking to maximize chamber space and fire multiple pieces simultaneously.
Fusing & Slumping Mold SetA starter set of kiln-safe molds so you can begin fusing, slumping, and draping projects the day your kiln arrives.
Glass Painting & Firing KitPaints, brushes, and firing accessories suited to fine glass painting and detail work in a personal-size kiln.
Bullseye Test Tile KitA pack of test tiles and color-compatibility strips to dial in your annealing schedule before you fire a finished piece.
Element Replacement KitSpare heating elements keep you firing without downtime. Elements are a wear item that eventually need replacement after years of use.

Common questions
What's the difference between the GTS 28 and the Studio Pro 28?They share identical chamber dimensions and capacity (5.8 cu ft), but the GTS 28 uses a firebrick-walled hybrid build while the Studio Pro 28 is all-fiber, and Quiet Drive ships standard on the Studio Pro but is an optional upgrade here.
What circuit does it need?The GTS 28 draws 40 amps at 240V, 9,600 watts, on a NEMA 6-50 plug. You'll need a dedicated circuit rated for at least 50 amps — have a licensed electrician confirm your service.
Is this a good size for a small studio business?Yes. 5.8 cubic feet comfortably handles multiple mid-size pieces per firing, which is a common sweet spot for studios selling finished glass work regularly without needing a 41-inch production kiln.
How is it shipped?At approximately 315 lbs, the GTS 28 ships via freight truck. Plan for a loading dock, liftgate, or forklift, plus help moving it into position.
Does buying from Peach State Pottery affect my warranty?No. We're an authorized Evenheat dealer, so your two-year warranty is fully valid and you have direct access to Evenheat's support team. Buying from an unauthorized seller can void your warranty entirely.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the Evenheat manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Evenheat dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
