So I have been using a UTH and have been maintaining temperatures perfectly but since it's starting to get cold it's been dipping down to 75 with just the UTH. I'm using a rack type system that's plastic. Everything is in a very small closet roughly 3x5. Would it be fine to just heat the small room with space heater and drop the UTH? So basically just set the heater up on the thermostat and remove the UTH. I'm thinking I'd set it to 83. I can't hook both up to the thermostat since it has a watt limit. Any suggestions? Thanks!
