I an going to add a kiln to my shop. My shop is a remote building that it is not practial to run 220 to at this time. I am looking at the Eveanheat 414 in 120V and was wondering if anyone had experence with thiskiln, and could tell me what the time to temprature was for 1450F and again for 1950F
 
I think it would take a long time to ramp up to heat. I have an Evenheat 220V and it takes about 20 minutes to 1500 and another 20 minnutes to 2000. How about just calling them and asking?

It is not going to matter if the oven is 220 or 120 volts the wattage is the same and therefore it is going to heat in the same amount of time. that said my paragon wich is 1800 watts heat to 1450 in about ten minutes and takes about 15 more minutes to heat to 2000 degrees.
 
I just bought the Evenheat 22.5 in 220. The manual said that it needs a 20 amp circuit. A 20 amp should use smaller wire to run than a 30 amp 220 circuit. So you mmight want to look at that angle. Ray Laconico runs a 110 Paragon in his shop, and from the conversations we have had, the 220 Evenheat is heatse faster and recovers much quicker. We have compare times head to head. Food for thought. Good luck!

I would expect your oven to heat faster. 220 volts times 20 amps = 4400 watts. for the evenheat.

110 volts times 20amps =2200 watts for the paragon.

twice as much power(watts) equals twice as much heat.
 
Aargh! :D

The 120V KH oven runs 1440 watts - 12 amps x 120V - only 12 amps so it can go (legally) on a 15 amp circuit. It is definitely slower than the 3600 watt KF22.5. I did time a 440C HT and got;

Time Temp
0:00 79F
4:03 400F
5:05 500F
6:15 600F
7:45 700F
9:35 800F
11:52 900F
14:48 1000F
18:21 1100F
22:44 1200F
27:49 1300F
30:00 1336F
34:40 1400F
42:13 1500F
51:19 1600F
60:00 1681F
1:02:06 1700F
1:13:27 1800F
1:25:44 1875F

Your results may vary depending on mass of your blades and surrounding temperature. There are from the KH18. Your 14 will heat somewhat faster.

WOW
Thanks Rob
Thats just the kind of information that I needed. This makes me think that it may be worth my effort to run 100' of 220v extension cord.:rolleyes:
 
Don't forget the cost of running half the wattage 4 times longer. Costs double the energy to heat it.

Not really. It's as fast as the 220V model for tempering temps. Cheaper actually.

In the higher range (1900 +/-), it's about double the time - essentially the same KW/Hr. to get to temperature - and the soak time is identical.

These are great little ovens for those who don't have 220. They are every bit as accurate - just a smaller chamber (still up to 18" deep) and slower to get to temperature.

I ran the wire for about a dollar a foot from the main breaker box to my recp. I think you could do the wiring project for under 200, and remember you are making at least a 1000.00 purchase in your oven. I bought a twist and lock receptical and built my own extension cords for my 220 volt KMG and 220 evenheat. The wire for the cords was NOT cheap. 1.79 a foot I think. :barf:

If you use an extension cord that long you need to oversize the wire to handle the extra current that will result from the voltage loss throughthe stranded wire. no big deal but it would be worth a phone call to an electrician to be safe. if I could remember the formula I would tell you what you need but Sh!t I'm getting old and have contracted CRS.
 
Well now I'm just as stumped as I was when I started. The Evenheat seamed to be the solution with a 120v kiln. Now that I may have to consider going 240v I Have to reconsider the Sugarcreek kiln.

Just for comparison of the 240 kilns:
Paragon KM24D chamber size 4.5"H x 5.5"W x 24"D, 240V, 8amps, 1800wats $1540.00
Evenheat KF22.5 6.5"H x 10" W x 22.5"D, 240v, 15amps,3600wats $1095.00
Sugercreek KK2 6" H x 8.75"W x 24" D, 230v, 11amps, 2530wats $497.25

Check controller in your comparison.

I have heard nothing but good things about them. They are a very reputable kiln company. I just emailed them about getting the digital controller and they responded immediately with price and a link to the exact controller that it would come with. Hopefully in a few months I will be able to swing one. For barely over $700 you can get a 24" digital oven. I reciently PM'ed balibalistic here on BF who owns one and he loves his.

Here is what Sugarcreek sent me:
Hi ,
The digital controller is available as an upgrade to the knife ovens. It adds $225.00 to the net cost. Here is a link to the manufacturers page on the controller tha we use www.ortonceramic.com/controllers/af3.shtml Hope this info helps Please let me know it you have any further questions. Thanks

Hey Mike,

You can build a 4.5"H x 5.5"W x 24"D, 240V, 16amps, 3905 watts for $300.00. That's what I did. Feel free to stop by and check it out if you are interested or drop me a PM. Build pics are on my web site under shop tour.

Whichever oven you decide on, I would recommend getting a digital controller. You will be glad that you did.

[I have a 220v Evenheat oven which has simply two 110v elements. I haven't used a 110v ovens but it stands to reason that it would simply have one rather than two elements like the 220v unit.]
