I’m getting a Spyder Robotics Herpstat HP version 2 thermostat to heat my reptile room to maintain ambient temperatures. (I have RHP and flexwatt for belly heat, basking... based on species.) My understanding is that an oil heater is the best/safest option? Which one? The room is 15x25. I also read somewhere that a digital heater will not restart if the Herpstat turns it off? That I need an oil heater with analog controls?
