    One pipe central heating system

    I recently made a start at converting my old 1-pipe system. See: https://www.diynot.com/diy/threads/one-pipe-central-heating-improve-and-add-a-rad.497803/#post-4092401 So far, I've converted 2 radiators and the difference is immense.

    I have an ole 1 pipe system which is performing quite poorly downstairs. The issues are the lounge and hall take a long time to heat up. I'd also like to add a small rad to a downstairs loo. The system is sketched in the attached. The area under the red box is inaccessible due to wood flooring...
