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.

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.
