Test it some day when you are around just plug it in and check it every 15 or 20 min and see what a 'run-away' will produce. I actually know what each of my enclosures will cap to in the event of a failure.If you can only get to 90 it just isn't enough wattage.

Rheostats work really well in a stable environment but do not work well in a fluctuating room my snake room can drop 8-10 degrees in a day so I'd have to check a rheostat every few hours it is too much work stable room temps are needed or a thermostat the herpstat helix is a great option.

That is the old style of 11" heat tape.

60*F is very hard to raise the temp. I think I remember the op saying the room was 68*F.

A 10*F change is VERY extreme. Even a proportional thermostat would have a nearly impossible time controlling that.
