Setting up tubs, mine are Hefty brand 52 qt tubs from lowes the site is down so i dont have direct measurements.
The warm side is perfect at 93.6 but the cool side is only at 70 degrees. Granted it's the middle of winter in wisconsin but my room holds at 65 all day, should i just up it to hold 70 degrees?
Any other ideas? I have holes also, if i plugged some would it hold heat in?
