Whats do you say that? (Not saying youre wrong, im just curious)

If one of the heat sources were to fail 1 of 4 things will happen:

1. The heat source that isn't being monitored by the thermostat stopes working and the cage gets cold and there isn't anything to warn you.

2. The heat source that isn't being monitored shorts out and gets really hot. The cage overheats and once again there isn't anything to warn you.

3. The heat source that is being monitored stops working and that cage goes cold. At the same the time The other cage gets really hot because the thermostat is trying to reheat the first cage.

4. The heat source being monitored shorts out and heat up. the thermostat detects this and reduces or cuts power going to the heat sources. Both cages go cold.

None of those situations are good, and they can be easily avoided by having 1 thermostat per heat source. Anything less is just being cheap and asking for disaster.
