It is fairly simple, you can buy a DIY garden tap kit, which it the tap and wingback elbow. A length of hose and a self tapping isolation valve. Instructions included.
These are ok for ease of installation, but where the valve punches a hole in the pipe - it leaves a ragged edge, this is where limescale and debri will build up (over years). The flow rate wont be great as it is only a small hole it punches.
or
You will need:
garden tap
wingback elbow,
non return valve (some taps have these built in)
isolation/ballofix valve,
PTFE tape
15mm tee,
15mm pipe,
2x 15mm elbow.
A cutting of overflow pipe/22mm plastic pipe to use as a sleeve to protect the copper pipe.
Pipework setup will be as follows:
tee - isolation - non return valve - elbow - sleeved pipe through wall -elbow -wingback elbow and tap.
Wrap 3 or 4 turns of PTFE tape around the male part of the tap, (in the direction of the threads) and screw into the wingback elbow.
Keep the pipework outside to a minimum, to prevent freezing. Also turn isolation valve off during winter and leave the tap open.
