My dad has asked me to ask this, I hope this is the right group
"Fitting a pumped central heating system, is it possible to take pipes down from the bedroom to the lounge and back up again, and from another bedroom to the dining room and back up again, or do I have to come down from upstairs and run piping all the way across the lounge to the dining room and back again?"
Thanks to anyone taking the trouble to help him out.
