Hello Rudolf,
try this www.laborofen.com
Efco and Uhlig have a cooperation. You can also try directly at Uhlig Ofenbau in Laudert, I already bought replacement parts there.
Hope, it helps
Doris
Anybody knows where I can buy spare heating element for my Uhlig U15 kiln? My kiln died last night and I have lots of work to finish :/
Thank you
R.
