For the purposes of a resistive load like heating cables, VA=watts.   So a 
minimum transformer for a 160 watt setup would be a 160VA 
transformer.   But it is likely to get pretty hot running at full rated 
load, so I would get a 200VA or 250.   They are pretty cheap if you found 
the right source.   I needed a pair of 500W transformers for a low-voltage 
lighting setup and found them on the web for about $65 each, a great 
bargain.   Just search and search.....
