I wouldn’t say that the tubs should not come in contact with the flexwatt. Many, many of people have tubs come in direct contact with flexwatt…..like in open air racks, with no issues what so ever.

Problems of tubs melting is a fault within the thermostat. This is why people shouldn’t buy cheapo’s and really invest on good quality thermostat.

In my opinion I would say flexwatt is safe if “controlled” ……extremely dangerous if not.

>>Your heat tape should not directly touch the tubs. There needs to be an air barrier to prevent overheating. If the tubs touch, you will soon see the tubs melting, and this could lead to a fire risk.

>>I build all of my racks with a 1/4 to 1/2 inch gap between tub and heat. Heat tape has the potential to get very hot, so this barrier will not be an issue.
