Can Underfloor heating suffer from airlocks

Can Underfloor heating suffer from airlocks similar to a Rad CH system

Looking at a house with UFH , dont know much about UFH, what happens if an air lock develops, how is that rectified

UFH is throughout house, (no rads) linked to an air to water heat exchanger (Nibe)

Nothing new there from heinbloed , he prob couldn't find a link to post .

What issues are you having with the underfloor heating , the manifolds should have either manual or auto vents to release air , also each room/circuit should have its own stat which operates an actuator on the manifold , when the circuit is calling for heat you should see the center of the actuator lifting , these actuators often fail , you can remove these to see if you get any circulation , the pin under the actuator might also be jammed like what happens with trv's , you won't get quick results in room temperature as it takes hours to heat a room with underfloor , but you should feel temperature circulation through the pipes at the manifold
