The 600 mm height clears a standard skirting and sits under most window boards. Typical job A room needing roughly 1235 W on a 70 C mean water temperature, or 1582 W where the system runs at 80 C. Straight swap for a tired 600 1300 single panel of the same size. Works with / replaces Pipe centres are 545 mm with a wall-to-centre of 40 or 55 mm, so it lines up with most existing 600 mm-high panels. Case depth is 56 mm against 70 mm for a Type 21 and 105 mm for a Type 22. When not to choose this The 1235 W figure is at T50.
