I have now got it on 60V and it is drawing 110mA so almost 7W of heat. It feels slightly lukewarm. I did say earlier I think 10W of power will be needed to get it nice and warm. Like you said it does not have to be D.C.. maybe a pygmi bulb and a variac will put enough power in the windings to warm them up!
