I own and recommend Skutt Kilns. I can't say enough good thing about their kilns and company! They are super easy to use, reliable, simple to maintain, and Skutt has some of the best customer service and tech support in the biz! In my studios I have 1 - KM1018 - A two ring kiln great form smaller loads and since it's shorter its easier to load, I'm a shorty! It requires a 50 amp breaker and can be run on normal 200 amp household service.2 - KM1027's - A three ring work horse kiln! Great for a studio potter wanting to consistently glaze fire to ^6. It requires a 60 amp breaker and can be run on normal 200 amp household service.1 - KM1227PK - My newest and biggest kiln with the ability to go to ^10 even with its larger firing chamber! It has the new computer touch screen as well! This big boy is direct wired and requires a 80 amp breaker and must be hard wired to your electrical panel or a junction box. Although this can be run on normal 200 amp residential service it does draw a large amount of power so be sure to check what else you are planning to run at the same time.
