Yes the coolers are heated. There is a Pro HeatTM radiant panel attached to the ceiling and a Ranco thermostat attached to the interior of one cooler that powers on and off all the cooler heat panels when it gets too hot or cold.
As far as I know, there are four people keeping Roatans in the US and out of us four there is only one female so three of us owners are clambering to get a female or a female offspring.
