Mr. Ronan Coffey:

If Deputy O'Sullivan does not mind, I want to go back to a previous question around the controllability of this heat. We can point to an example in our Galway plant where we built a 40,000 sq. ft controlled environment for medical device manufacturing. This was our first heat pump-fed, clean room environment in Ireland. It has been operational for two years now and working very efficiently and effectively. It is very much a proven, low-risk technology. I know there is debate about controllability when it is retrofitted to domestic houses. However, that is a totally separate discussion. In industry, in the qualified environmental control realm of medical device manufacturing, we find that this technology has proven itself.
