Hi everyone! Have been playing with my new kiln and LOVING it!!! Thinking
about pre-emptively buying stock in the electric company to recoup some of my costs in running the thing day and night. But aside from the fact that glass will be making me a pauper in short order, working with warm glass is fascinating! With that said, I wanted to find out if this is truly the forum for discussion of warm glass (I have SOOOO many questions!) or should a new newsgroup be initiated. 'Cuz time's a-wastin'!!! I need to SHARE and TALK and DISCUSS this new love of my life!!!! Boy, I am such a girl!!! LOL Look forward to hearing from you all (yep, even you sasspots!!!) Lori |

Lori Cost of electricity is much less then most expect. If the label on your kiln doesn't specify the wattage of your kiln, you can calculate it by multiplying the amperage X the voltage. Then check your power bill for the price per kilowatt hour you're being charged. Multiply that price X the wattage X 4 hours (that's the average amount of time your kiln is actually consuming power for a full fuse firing). As to establishing a new group, why reinvent a wheel that already works perfectly?

Lori Glad you're enjying the kiln - there's an awful lot to learn - but the best way I've found is to experiment, and keep notes ! There's lots of expertise over in the warmglass forum - but I personally find it much easier to read this newsgroup, rather than keep checking a web-based offering. By all means ask away here - what sort of kiln do you have and what are you making with it ? Tried any dichroic glass yet - that's lovely stuff to play with !

Glass Campus - http://www.glasscampus.com As usual, Brady, in your rush to look important you offer more WRONG information. Definition: A kilowatt hour (KWH) is 1000 watts of current flowing for one hour. (Kilo=1,000) Eh? Once the wattage of the kiln (or any electrical device, for that matter) is known, that wattage figure must be DIVIDED BY 1000, "then" multiplied times the hours (or fractional hours) of use and "then" times the KWH price rate to determine cost of operation. It's grade school math, you dummy. I know you aren't too smart, so read slowly and look at these examples, maybe you'll get a clue: An 1800 watt hair dryer used for 15 minutes at $0.10/KWH is (1800/1000)x (15/60)x $0.10/KWH =$0.045 cost or less than a nickel to dry your hair. Running a 150w power supply on a PC left on for 24 hours would be: (150/1000) x 24 x $0.10/KWH = $0.36 per day. My electric bill came today. We used 1079 KWH in a 31 day billing cycle and the bill was 75.90 plus taxes. That's about $0.07/KWH, so my examples above are off a few pennies. A 40A/220v kiln is 8800watts, or 8.8KWH if it runs for an entire hour. On a hypothetical cycle of 4 hours, that is 35.2KWH or about $2.46 at my local electric rates. Once again, the Canadian prairie dog pops out of his hole, barks a bit, and takes a round right between the eyes. When will you ever learn? |

Moon's calculation would be fine if the heating element in the kiln was 'on' throughout the whole of the firing cycle. This isn't the case - on my little SC2 kiln you can hear the relay which switches the power to the element clicking in and out as the controller attempts to provide the required temperature rate. The elements will be 'on' for a shorter period of time as the kiln ramps down - and may not even be on at all as the thing cools to room temperature. Even with a 'manually' controlled kiln, I think that you control it by switching resistance in series with the elements - which reduces the current and so the power consumption. I guess the only 'simple' way to find out is to actually fire your kiln with some means of measuring power consumed - or run it for a cycle with all the other electrical 'things' switched off - and read the utility meter at the start & end of the cycle. In the grand scheme of things, it's one of those things that's probably not worth the effort of calculating g - as a very rough rule of thumb you could take Moon's figure and divide it by 1/2 or 3/4 - probably wouldn't be that far out....

Hi again
big snip OK Adrian - back in your hole ! (ducking those bullets g) I see that Dennis has taken the intermittent nature of the power consumption into account - sorry - should have read it all a bit more closely.... FWIW - the webpages over here (UK) claim that the SC2 costs less than 50p to run a 'cycle' - that's just under a Dollar to those of you in the USA. At those sort of costs, and on a 'commercial' basis, the electricity involved in running the kiln is a tiny amount of the costs involved in producing saleable items - so probably not enought to worry about... To swiftly paddle my canoe into less controversial waters (I Hope!) - I'm toying with the idea of buyinf another kiln. The Paragon SC2 is great for little pendant pieces - and for smallish dishes / kiln-cast pieces - but I'd like to be able to make larger pieces - say up to 12" diameter. One UK retailer is offering the Skutt HotStart Pro or the Paragon Fusion 7 - for about UK Pounds 720 - 750 each inc tax. (About $1300) Any comments for or against these models - or suggestions for an alternative...? We're moving to Ireland in the near future, where the 'purchase tax' is even higher - which is why I'm thinking about a new kiln 'now'... Thanks in advance Adrian Suffolk UK ======return email munged================= take out the papers and the trash to reply |

Hi Moon

In a 6-8 hour firing cycle, the elements would be "on" the 4 hours used in the illustration. ;) Yes - I apologise - I didn't read Dennis's post closely enough.. but I did post an apology once the penny dropped... In my defence - it was early, and I was up half the night with a migrane...... .....not that I'm expecting any sympathy g Regards Adrian ======return email munged================= take out the papers and the trash to reply |
