I have a couple oil-filled radiators from DeLonghi - and I love them. The first time you use it you may notice a smell, and I don't know if that can be harmful or not, but there is an easy fix, plug it in your garage, or on your porch, or basement, any area well away from your birds and just let it run for a good 24 hours to 'burn off'. It has so many advantages, one of the most important is no fan to blow heated air onto the birds that could be detrimental to their breathing, and to their skin and oils, etc. They are also very clean, there is no open coils to burn you, and you can even touch them without being burned - another major consideration for bird owners.
