Tried out my new boiler as well and my improvised IC which I cobbled together last night. All good. 
This was taking notes from the thread I posted up about a hoppy, pale ale. The recipe I ended up with was:
4.55kg crushed pale (66'C mash for 90 minutes, stirring every 30 minutes)
250g wheat malt
50g Cascade for 60 minutes
35g Cascade for 12 minutes
15g Cascade, 20 minute steep at the end
Whirlfloc tablet
1/2 Campden Tablet
Danstar Nottingham yeast
Pics will follow shortly (when I can get the hosting site to get it's act together). One thing that really puzzles me is the apparent efficiency I've obtained.
Previously, when doing 16 litre boils (so I've had to stop the sparging at that volume), I've achieved about 75%. Now with sparging a full 25 litres, I was expecting an increase, so I budgeted it at 77% to be on the close side, the beer software giving me an estimated SG of the finished wort of 1051.Interim measurements were much higher than this but I decided to wait until I had a cool and ready to ferment wort to try again. The reading was 1061.
This was with the correct temperature adjustment too. I did top up the fermenter slightly with some water (as the new boiler seems to "steal" about 5 pints at the bottom of the barrel which is below the level of the tap) with a new SG of 1059. But even so, that's still considerably more than the calculated OG. 
There is only one thing I can think of: this was using my new 25kg bag of grain, which I had emptied into two 25 litre containers. I think I might have taken the grain from the last of the two and the flour etc. which was settled at the bottom of the grain sack had been at a greater concentration for that last bit, resulting in a lot more convertable material in my mash? Thoughts?
Still, was a good brewday. About 6 hours, but I wasn't as efficient with my time as I was with my mashing.
Hoping to have this one ready for Christmas!
