When the system is cold the F&E tank only needs to be 1/3 full.
thanks dave much appreciated
And when the entire system is at its maximum working temperature, the water level should still be a good few inches below the level of the overflow.
The operative word here is that it's an Expansion tank. Lots of them are incorrectly set up as water storage tanks. The damage that can be caused by a few decades of a small overflow on start-up is mind boggling.
It's best to switch to a sealed system with an expansion vessel in most cases.
