Just had a new ground floor extension built and the plumber has taken a feed from the main heating circuit from the boiler that runs under our easily accessible ground floor void, run 15 speed fit pipes back up into the roof of the extension, and then fed back down to each radiator. We have four radiators in total being fed this way. Does this make any sense to anyone else? I was expecting the heating supply to get put into the floor of the new extension (since the screed had not been laid at the point of first fix for plumbing, a 22mm pipe extension from the existing circuit stepped down to 15 mm for each radiator; with each radiator being fed upwards from the floor.
