Flexwatt heating

So I am using flexwatt in my racks to heat my tubs. My question is, is it safe for me to set my flexwatt to 102 degrees. The only reason I am doing this is because my tubs dont sit right in the flexwatt, because I made the spacing a little too much, I had to put thin pieces of hardboard under the tubs to keep the containers flush against the top, so they are sitting anywhere between 1/8-1/4 inches over the flexwatt. So is keeping it at 102 safe to transfer the heat through the air and still give them a decent amount of warmth?

I don't know if you will get good heat transfer without the flexwatt tape contacting the tub. Could you glue or nail something on top of each tub space to close the gap? This would give you the contact that you need.

Good Luck!

So if i put some sort of thin plastic between the flexwatt and the tub it should hold and transfer the heat??

you know, its okay if there is a 1/8"-1/4" gap between the tub and the shelf above. That is actually preferable.

Plastic can act like an insulator, if you can get a piece of aluminum cut to the size of the flexwatt tape, that would be best. Aluminum comes in a number of thicknesses, so you should be able to make it work.

You would need to measure the temps yourself to know for sure. If you're asking because you're worried about things melting/catching on fire don't worry about it.

Hi,

If your getting humidity resistant materials cut why not put them at the top stuck to the surface above the tubs so that it still narrows the gap but the tubs are back on the flexwatt? :P

Not sure if you're interested in changing your set up, but this is what I use. Or at least you can see how far my tubs are from the flexwatt.

Best to measure temps inside the tubs! You can add plastic to the bottom of the shelf so the top of the tub is closer to it then you can sit the tubs directly on the flexwatt!

My setup is almost exactly like this with the same space between the flexwatt and the tubs...what is the temp on your thermostat set to??
