Authorized Evenheat dealer · full factory warranty

Brand new and shipped direct from Evenheat, so it carries Evenheat'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

Not included: kiln shelves, posts, kiln wash and downdraft vent (sold separately). Requires a 240V single-phase circuit (45A, 10,800W) with a NEMA 6-50 receptacle.

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).

Corner-Mounted HardwareLoad-bearing hinge and lid handle brackets installed on the corners provide added strength and durability. The extra-wide 16-inch lid handle is designed to be easily lifted while wearing gloves.
Lid Security BarKeeps the lid securely open during loading and unloading for safe, simple operation without the need to prop or hold the heavy lid.

Common questions
What makes the maintenance line split jacket different from standard kilns?The RM II 2329 features a vertical split in the stainless steel jacket that's held together with removable screws. When you need to replace elements or access the interior for maintenance, simply remove the screws and separate the two jacket halves. This eliminates the need to disassemble the entire kiln or work through awkward access points, saving hours of labor during routine maintenance.
Can this kiln handle production work or is it better for occasional firings?The RM II 2329 is explicitly designed as a workhorse for production studios, educational programs, and high-volume operations. The 2.5-inch brick thickness provides excellent heat retention for energy-efficient back-to-back firings, and the optional Quiet Drive relay's zero-crossing technology extends element life even with frequent use. Many production potters run these kilns multiple times per week for years.
How does the 7.5 cubic foot capacity translate to actual shelf space?With a 23.5-inch diameter chamber, you can fit standard 22-inch round shelves or 19-inch square shelves with plenty of clearance. The 29-inch depth allows for 5-6 shelves with typical spacing, giving you room for tall pieces, large platters, or high-density loads of smaller production work. This is one of the largest chambers available in a top-loading electric kiln.
What electrical service do I need for this kiln?The RM II 2329 requires 240V single-phase service. It draws 45 amps (10,800 watts) and comes with a NEMA 6-50 plug, so you'll need a dedicated circuit with a NEMA 6-50 outlet. We recommend having a licensed electrician evaluate your studio's electrical panel capacity and size the breaker before purchase. Contact us if you need a different voltage and we'll provide exact electrical specifications for your electrician.
Does buying from Peach State Pottery affect my warranty?No. We are an authorized Evenheat dealer. 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.
