This has been so frustrating - been trying to set up a qt tub using a zoomed uth hooked to a helix but can't seem to get it warm enough without setting the helix at 100 degrees - is this normal.

My room is at 75 degrees. The tub is a small 15qt.

Any suggestions as to why I am having such a hard time. Heating this tub.

I adhered the uth right to the tub in hopes of getting more contact/heat to the tub. I'm using a temp gun and. My temps are 79 hot side and 71 cold side which I know isn't acceptable.

I bring her home today and need help asap. Thanks
