has anyone seen the ceramic heaters they use for reptiles? they screw into an incandecent light fixture like a heat lamp. they wont be a probem to use around birds right? I dont plan on using directly on any birds but it will be in the same room heating a lizard tank.
I have those ceramic heaters in all my reptile cages and they do work perfectly
inside a cage. Unfortunately even the biggest available one is not sufficient enough to heat up my whole iguana's body and makes no difference to the temperature inside his room. So it wont work for your bird because the cage is open and wont trap the heat.
I used to use the oil heaters that you are referring to but since electricity prices skyrocketed in South Africa I had to start looking around for alternatives. I have a house full of animals that all require heat and my electricity bill went up to R5 385.00!!!!!!

We switched over to econo heaters and it works perfectly!

It only uses 400w to heat up a complete room and is animal and child safe. A normal bar heater is usually 2000w. I have them all over in my house and also in my iguana room. He is from the amazon and requires humidity of 80%+ and I can safely say that the heater does not dry out the air.
Here is the website and if you click on Global Distribution you will see that they are located all over the world.
