Authorized Olympic dealer · full factory warranty

Brand new and shipped direct from Olympic Kilns, so it carries Olympic's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.

Warranty terms are in the Warranty and support section below.

Returns: request within 15 days, unused

Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:

  • Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
  • It must be new, unused (beyond the factory test fire) and in its original packaging.
  • A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
  • Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.

Will it work in my space? Power check

Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.

Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

Overview

Olympic Kilns · Electric Kiln · Oval Olympic 2527HE Oval Electric Kiln 2527HE · 208/240V, 1-Phase or 3-Phase · 37″ W × 25″ D · 12.8 cu ft · Cone 10 / 2350°F The 2527HE is Olympic's large-capacity oval kiln, built to fire long, wide loads that a round chamber simply can't fit — platters, large sculptural work, and full shelves of production ware. At 12.8 cubic feet it holds significantly more than a standard round kiln in a similar footprint, and it ships with a combined lid lift and stand plus a built-in electronic controller, so it's ready to go to work the day it's wired in.
Max TemperatureCone 10 / 2350°F
Firing Chamber37″ W × 25″ D / 12.8 cu ft
Voltage208/240V, 1-phase or 3-phase
Breaker RequiredUp to 80 amp
What’s included
The kiln, with its elements installedThe brick sections arrive with Olympic's heavy gauge coiled elements already set in their grooves and wired. This kiln ships as sections on a pallet together with its stand: the manual has you take the sections off the pallet and restack them on the stand where the kiln will live.
Bartlett KilnStar controller, fitted and wiredThe KilnStar is the standard controller on this kiln and it is installed and wired at the factory. The Genesis touchscreen is a paid upgrade taken at order time, and Olympic's 2026 range no longer offers the RTC-1000, Kiln Sitter, 3-key or V6-CF, so nothing legacy ships here.
One Type K thermocouple and the pilot lightA single Type K thermocouple comes installed and wired to the controller. The control panel also carries a pilot indicator light that comes on whenever the kiln is live. Extra thermocouples only arrive with the 2-zone or 3-zone option, and a Type S is a paid substitution.
The combined lid lift and standOlympic's oval line ships one assembly that is both the stand and the lid lift, so the lid assist is built into the stand rather than added to it. The manual requires it: “Your kiln must be fired only on the metal stand provided.”
Observation plugsHollow ceramic peephole plugs ship with the kiln. Olympic publishes no count for any model, in its manuals or on its site, so we will not print a number here. Ask and we will confirm yours with the factory. Replacements are a stock part.
The operating manual and a one-year warrantyOlympic's printed operating manual travels with the kiln. Olympic's limited warranty runs two years, cut to one year on Kiln-Sitter models and on any kiln rated at cone 10. This one is rated to cone 10, so one year. Register with Olympic within 30 days of delivery and keep your invoice.
Cord and plug, or direct wired, set by your buildOlympic's plug configuration row gives a NEMA 6-30 or 6-50 plug on lower-amperage builds and Direct Wired on higher-amperage ones, and several models are listed as either. The manual hedges the same way, with “If your kiln is equipped with a power cord...”. Tell us your voltage, phase and service and we confirm which one you get before the order goes in.
Not included: furniture, vent and hookupNo kiln furniture. Every Olympic line has its own separately priced furniture kit and shelves and posts are priced one by one. The VentMaster downdraft vent, stilts, gloves, tongs, kiln wash and a pyrometer are all separate items, and no receptacle, breaker, wire or disconnect ships with the kiln.
Key features
KilnStar Digital Controller Pre-programmed with Cone Fire and Ramp/Hold modes. Features delay start, alarm, and thermocouple offset adjustment.
3-Inch Brick Insulation High-efficiency firebrick construction reduces energy consumption and improves firing performance to Cone 10.
Oval Firing Chamber 37″ wide by 25″ deep oval chamber fits long platters, large sculpture, and wide production loads round kilns can't accommodate.
Combined Lid Lift & Stand Integrated lift-assist mechanism built into the stand makes opening and closing this large, heavy lid manageable for one person.
Stainless Steel Jacket Durable outer shell with corrosion resistance. Provides structural support and a clean, professional appearance.
Balanced Element Design Heavy gauge coiled elements arranged across the oval chamber for even heat distribution during Cone 10 firings.
Observation Plugs Peepholes at multiple chamber heights let you check pyrometric cones visually during firing without opening the lid.

Common questions
Why choose an oval kiln over a round one?
An oval chamber makes far better use of floor space for long or wide ware — platters, trays, sculptural pieces, and wide production shelves — than a round kiln of similar capacity. The 2527HE's 37″ width lets you load pieces that simply wouldn't fit through the opening or across the shelf of most round kilns this size.
Do I need an electrician to install this kiln?
Yes. The 2527HE is direct-wired and requires a dedicated circuit sized to your configuration — up to 80 amps for 1-phase 208V service, or as low as 50 amps on 3-phase service. A licensed electrician must determine the correct breaker, wire gauge, and connection for your building's available power, and installation must meet local electrical codes.
Does the lid lift assist come standard?
Yes. The 2527HE ships with a combined lid lift and stand as a standard feature, not an optional add-on — given the size and weight of this lid, it's built in from the factory rather than sold separately like it is on smaller Olympic models.
Does this kiln come with shelves and posts?
No. Kiln furniture is sold separately because different users have different needs based on the work they're firing. For a 12.8 cubic foot oval chamber, we recommend a furniture kit with multiple full-length shelves and a full assortment of posts and stilts. Contact Peach State Pottery for a recommendation sized to your typical loads.
How do I register my warranty?
Register your kiln at the Olympic Kilns website within 30 days of delivery. You'll need your serial number (located on the control panel label), purchase date, and proof of purchase from an authorized dealer. Warranty registration is required for coverage and must be completed within the 30-day window. Peach State Pottery can assist with registration if needed.
