All, this is what I am planning in my new ball python room:
1) 2 oil filled radiators connected to the same thermostat (with a back-up thermostat) in case one of the radiators or one of the thermostats fails.
2) An A/C wall/window unit for the summer also connected to 2 thermostats in case 1 thermostat fails.
3) A fan at ceiling level at one side of the room circulating the heat/cooling 24 hours a day.
4) Controlling the heat spots on the racks with heat tape and Herpstats.
5) A single thermostat to the power to the entire room which cuts power if it gets above a certain temperature.
6) A temp and humidity sensor which connects to my home wireless and sends me a text if the temp/humidity goes above or below a certain range. Was thinking of this one. Seemed like good value for money and will give me some peace of mind.

Still doing research on the best quality oil filled radiator and A/C unit. All ideas welcome.
I am just a little nervous on relying on the build in thermostats that come with the radiators and A/C units. Sure they will be fine and work well but always like to de-risk and build in lots of back-up.
Considering these 2 thermostats but they are not cheap and I would need 4 of them.

The Johnson Controls stat only appears to have a limit of 12A which is roughly 1400W at 120V while the Durostat one is safe to 30A.
Also, think that an air extractor is necessary?
All ideas very much welcome. Sorry, kinda anal about getting this right.
Thanks
