Is it possible to use PVC tubing (or any other type) for a wort chiller?
It is a thought but, I do not think you will get the performance you will be looking for.
*What would be tha cost for the PVC?
*What is the time taken to cool the wort with PVC?
Check ebay for copper tubing. I just bought 100' for $74 plus shipping. I built a 50' wort chiller for myself and plan to build two 25' chillers to sell on ebay to recoup my original cost.
