Copper pipe

[Ronanc89]

Thanks for the help guys! Im guessing 10m of the stuff would make a pretty nice chiller, but how large a diameter should i aim for? Im guessing the bigger the better as it will result in a larger surface area.

Generally people use a paint tin or even a corny keg as the guide for diameter.  You want it to fit in your boiler and presumably you wouldn't want it too close to the sides and finally you want it to be conveniently stored.

I can say from experince this only works if the pipe comes pre-coiled!

Yeh too much hassle if its straight. Was actually wondering what size diameter in relation to the pipe itself.

Not too many places selling 30 Metre lengths of 10mm straight pipe chaps
standard sizes are 8 and 10 mm coils in 30 metre lengths.
I used a corny the first time and a demi the second to add an extra 10M to my chiller to brew pilsners, the coiling bit is easy the returns are difficult and I have a pipe spring for the purpose.

For the returns you can use some basic soldering (use tin lead free solder). This involves a couple of straight lengths of copper connected via right angle bends at the top and the bottom of the coil. See the following video for how to do it.

I used a gas pot to bend the copper around. 2 sets of hands helps alot but not impossible on your own. I made the bends to the straight inlet and outlet around a handy size pot. By the elbow joints as a just in case the bend goes wrong. They don't cost much.
