I cam get two types of heat source.
One is big back heat foil something like 2m X 1m it is use to heat under rugs and stuff…
I can put it on the back of the racks system, that way i can sandwich two racks between one heat foil. I am sure it can get to 32 C no problem(i will have thermostat of course ) and gonna go around 31C with probe on floor level on in the middle of the rack.i guess that this is going to give me smaller gradient in tubes cause it is going to heat the whole system ,whole rack …
Another one is rope -cable heater…those i guss is going to give me bigger gradient difference in tubes. Because it is going to be under tube and probe is going to be above it on ground level of tube so it is going to get 31C pretty quickly …and it is not going to heat the whole rack but just more concentrate ..more like spot lamp.
If u think rope is better can u recommended how much W?i read in one book that 7W by foot is ok. It is something like 21-25W by 1 meter…i can get heat ropes like that!
What do u think it is better!
