Pump Action recently completed the installation of a new Reflex thermal expansion system for a district heating network in Bonnyrigg, just outside Edinburgh, replacing the site's old Hoval system.
Our engineers Jock, Rory, Charlie and Rab installed the new expansion vessels and controls, giving the network reliable pressure maintenance and better protection for the wider plant.
