Heat tape question

[Oxylepy]

Understandably so. But as a heads up, if the strips of heat tape are the same size, you can run multiples off the same thermostat. It would be wise, however, to keep as many variables the same for each tub, though. Same size strips, same dimensions of shelf space, same tub size, and same wall coverage (avoid open backs or sides).

Ideally all variables are the same as with most commercial rack systems. The shelves are all the same size, tubs are all the same size, the heat strips all have the same coverage, etc. You can get away with some differences (double wide tubs, for instance), but you want to minimize those differences.

If the whole thing is open front and back, leave it that way, if the sides havr backing but the middle doesn't, get backing for the middle.

With a wider middle than the sides, be careful with probe placement. If you put the probe on a middle shelf, the sides may be too hot, if you put it on a side shelf the middle may be too cold. But most importantly, make sure all the heat tape sections are the same length, otherwise the power sent to one will be different than the power sent to another. If it's all one giant strip you should be fine.

Be careful with wattage, with so much length you need to make sure your thermostat can handle it (if it's a 500w thermostat and each foot of strip uses 5 watts, that's about 100ft of heat tape maximum, going less is better)
