Portable Electric Heaters-Safe?

everyone knows that i am going to get a 'tiel now i am worried about the winter.
my dad turns off the Heater and uses the wood stove.
So i dont want my 'tiel to get sick so i was wondering if Portable Electric heaters are safe?
Surely they dont have ionizers and i can make sure there is no teflon coating or ionizers.
i was looking on the internet and found This portable electric heater something like this or other.
Nothing to take up to much room just to keep my room nice and warm im even considering in the winter to move the cage to the wood stove area.
So if anyone knows of any place i could get a good electric heater and if they are safe please let me know
i would appreciate it very much.
Also could they dry out the skin and feathers?
I hope not. I wouldnt have the cage close to the heater at all.
