so many pipes in my airing cupbaord, what are they!!! All aspects of plumbing questions and answers, help, tips and information

[stevehayes]

I have started a plumbing course and have briefly started on hot water. I know most systems nowdays are indirect and have a primary flow and primary return as well as a 450mm offset to the vent pipe and hot water draw offs. But in my airing cupboard, there are many more pipes, a grundfos pump and a motorised valve! I know some of these are for central heating, but i just wondered if anyone could help me in naming the other pipes!! It's very confusing!! thanks for any advice/help that anyone can give me!
