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.

Read the full return policy

Will it work in my space? Power check

Not included: blade fixture, loud alarm, tongs, gloves and foil (sold separately). Requires a standard 120V circuit (13A, 1560W) with a NEMA 5-15 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).

Common questions
Can I plug this into a regular household outlet?Yes. The KH 418 is specifically designed to run on standard 120V household power at 13 amps. It has a standard NEMA 5-15 plug, plugs into a standard 15-amp outlet and doesn't require an electrician or special wiring. This is the main advantage of the KH Series over the 240V models.
How long does it take to reach hardening temperature?The KH 418 reaches 1650°F in approximately 90 minutes. Because it runs on 120V instead of 240V, it takes about twice as long to heat up compared to higher-voltage models, but it absolutely reaches full temperature and maintains tight control once there.
What size blades can I heat treat in this oven?The 18-inch depth accommodates most knife blanks, including large chef knives, bowies, and swords up to 17 inches long. The 6.5 × 4.25-inch cross-section handles typical blade widths easily. This is the deepest KH model and the most popular choice among bladesmiths.
Is 2200°F hot enough for all knife steels?Yes, 2200°F covers the vast majority of steels used by knife makers and small machine shops. Most popular blade steels like 1084, 5160, O1, and even many stainless steels harden well below 2000°F. Only specialized high-speed steels require higher temperatures.
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.
