Actually they do very good down to 32 gets marginal after that. I routinely have them on at 29 or 30 and they keep it warm but not so comfortable that i dont need long sleeve pajamas or if i am on the couch I have a throw over me. but it is a long ways from cold with them on. They actually seem to go over to the furnace somewhere around 25. They just switched to the furnace a few minutes ago and it is 20 degrees out. I am not sure where the temps switches but i assume has something to do with how warm the temp in the heat pump is or how long it is on without warming. I dont know for sure though. We have had out 1500 watt infrared heater on since the temp was about 35 outside.
