Gledhill 450 Torrent RE [solved]
What is the top pipe connected to my Gledhill Torrent 450 RE thermal store?
It comes out of the very top of the tank. Not on the side but right on the top in the centre?
Looking at the installation and service manual, it appears to run to a feed and expansion tank to allow the water in your system to expand and contract safely as it heats and cools.
