Why do I see people putting reflectix 'ontop' of the flex watt? Never made sence to me, each row of flexwatt is heating the tubs above it... so why put insulation between the flexwatt and the tubs.


(________) tub
======== reflectix
----------- flexwatt

I dont see how this makes sence, if anything you should lay down reflectix then put flexwatt ontop of the reflectix so that heat doesnt radiate down, but all goes up to the bottom of the tub.
