Heating the Giant Glass Bed

[cilynx]

I'm currently using 100ft of 120V pipe wrap. It pulls ~1100W at room temperature and is down to ~375W in the ballpark of 40C and that's all the higher it goes in the current arrangement. Next step is to come up with a mechanism to arrange and hold the coil for maximum uniform coverage. This will both reduce hot/cold spots on the bed and may get me a bit more power as well as the coil appears to have a positive temperature coefficient so reducing its hot spots might keep the overall power higher.
