How important is the depth. The level in my expansion tank is 175mm ensuring that the bottom of the overflow pipe is always under water. Could this explain why I continually have to bleed the system ?

It will explain why your garden is being watered regularly.
Can you check as your overflow pipe should be around 150 mm from the top of the tank.
It is the overflow pipe. It exits the tank 70 mm from the top but if you can picture an upside down L shape that is 170 mm from the top and hence 25mm or so are submerged in water
