I have to disagree with this statement. I've had no issues with room temps dropping down to as low as 70 degrees. It's dependent on the size of your UTH and the size of the tub, and how good your T-Stat is at maintaining even heating without big swings in temp.

I ran this system for almost a year with no issues before I switched to racks.
