Hot IS great, i use mine all the time. Those of you who say it isnt needed havent used it 
I wont say its faster, it really isnt, its just a joy to work with.
Daz why you didnt leave it all plumbed in i dont know, it wouldnt of hurt to leave it in and turn it off.
You're right , i haven't used it and i haven't needed to find out

I'd probably like it, but i cannot see how it will make me any more money, it would only add to my expense.
Sorry Daz, I'm deviating from the original question and turning it in to one of those "is hot water better or necessary ?" arguments

I think LWC has a valid point though, why did you take it out ? I think you are probably one of the few ( if not the only ) who would bother going to the trouble .
