Thanks again Kev.
Hmmm, got me thinking now (which is good)! A freezer located through a wall isn't an option due to house layout unfortunately. A standalone bar is possible if tricky $$$ and space-wise. When you suggested a standalone bar was that purely for the bling factor? Or would it have some impact on font temps? (I'm guessing it was just the looks)
Celli taps are out of reach at this stage.
I'm now thinking I will go with the font on top of the freezer, with lines insulated once outside the freezer. If I'm still getting warm beers then I'll look to retro-fit some sort of font cooling. Maybe put it on a timer so that it is only keeping the font cool in the evenings (& weekends!) to reduce power usage. I'll get some searching done on here on that front.
If the ambient temperature in the pub is usually say no higher than 20 degrees, do you think that will cause enough of a problem to need fixing? Hard to quantify what someone else calls a problem I know, let's just say I don't want warm beer or too much froth.
Cheers again for the help, I really appreciate it.
May be worth looking up some of the Coffin Keezer builds popular on the US homebrew sites. There are some mind boggling creations out there. Limited by time and $ only.
