Hi Bill, I wanted to thank you for all your help and expertise. I had the electrician come and run a fresh copper wire. I received the elements from Euclid’s and I fired yesterday and it went wonderful. I hit a 04 bisque in about 5 hours … guessing it’s the new elements plus correct voltage and power. I also added the fans going out to not pressurize heat in the garage. It went great because it was actually really chilly here in Jacksonville so I didn’t smell no toxic fumes and the room wasn’t hot. The water heater is thankfully electric and more than 6 ft from where the kiln is located and yes garage walls are block like and the floor is concrete. I’ll keep the post updated as I go but i anticipate my glaze fire will go well. Any advice on holding heat in a manual kiln? Anyways thank you so much , I really appreciate all the help!!
