I have 3 zones of wet under floor heating.
It isn't getting as warm as it used to.
Could it need bleeding? How do you bleed under floor heating?
I can't see anything obvious on the valve mainfold.

Manual mixing valve on manifold going out of calibration possibly, check with thermometer to see what temp is coming out of it.
