UFH manifold query

[stoky house]

Hello

I'm new to Buildhub.  I am a home owner.  I live in a small 3-storey house with underfloor heating (no rads at all).  The UFH doesn't work too well.  Could this be anything to do with there being only 1 manifold (on the middle floor)?  If so, what are my options?  I don't think it will be viable to change the design....would it be possible to introduce an annual air-bubble removal process?  How would that work?  Any advice you can offer will be most gratefully received.

Could you elaborate ?  a bit more information on the problems would be welcome.

Which floors have underfloor heating ? and what are the floor coverings.

Is there air in the system ?   There may be an air release valve on the manifold and/or somewhere else in the system:-

ours on the manifold looks like this, the black cap on the top [like a tyre valve cap] is the manual air release, it will let water out if there is no air in:-

 

Also in the system there may be something like this?

 

 

 

What is the heat source?  And what and where are the controls / thermostats?

 

Cheers
