I feel like I see people asking this a lot, how to keep a tub warm enough in a room with cold ambients. Obviously raising the ambient room temp or using a space heater is ideal. However the posts I usually see are people with maybe one snake who can't really justify a space heater or making their room that warm. I needed to set up a quick stand alone tub and unfortunately the only place I had was near an air conditioning vent 🥲 So what I did was take a 28 qt tub and get two heat mats. Each large enough to cover 1/2 the tub. Set it up, sodered holes, got thermostat probes where they need to be. It's been up and running a few days now and temps are holding steady. Using wood shavings as bedding, not sure if that makes a difference or not. Average temperature of the area before was 67-69 never getting above that. Currently the bin is reading 75 on the cold side and 85 on the warm. Ambient temps above the bin and a few inches to the side read 72, though this would probably be slightly higher using higher mat temps. Keep in mind this specific bin is for a soloman island boa and these are their ideal temps. I ran some tests and it can easily do 80 on the cold side with a warm of about 90 depending on what you need. All temps were taken with a temp gun, and thermostats used on both heat mats. Thought this might help someone! I ran for a good amount of time to make sure everything was consistent.
