I made a DIY UG heater as per instructions given by Uwe Behler on
*.aquaria. I used AWG 30 wire wrapping wire as it was the thinnest
wire with adequate insulation I could obtain then.
I found some heater cable in a electronics surplus shop the other day.
On it, there are some markings
E56198 RU AWM 3323 200 C 300 V
which means it can stand up to 200 degree centigrade and 300 volts.
The resistance is 90 Ohm/yard. I think it may be useful for DIY
UG heater. It costs about $1 per yard. If you are interested in
getting some, please send me a message. Do not reply to the list.
