HOW CENTRAL HEATING WORKS part 1. The history of central heating pipe layouts

[@rajan246]

Loving the cultural references and trivia, Derek. An educationally entertaining breakfast watch!

[@peterfido8735]

Would it be okay to pipe the whole of my central heating system not just the flow and return, obviously step down to 15mm when connecting to the radiator pipes under the floor. The only reason I ask is I have enough 22mm pipe for the job and don't want want to buy any 15mm if I don't have to .

So he's British accent makes it difficult to understand a English video. Ok silly bollocks.

[@justinomademo302]

How you can't understand the accent? How other nations understand us in the State? Are we better than the British? I think our English came from the UK.

Lol Didnt boil. You think. My mother only had her coal fire 10 years ago. Still used to boil and she used to turn on kitchen tap to run it off, Finally got her to stop chopping sticks and turn to gas when she was 75 years lol
