Hi All
Went to see customer with an UFH problem. Pump not working so replaced, but still no heat! Have heat to manifold via open 2 port motorised valve. Heat starts to enter UFH pipes but does not flow through to return manifold. System has 2 auto air vents but cannot get any air out. Have tried attaching hose to return manifold to purge some water and hopefully some air but no joy! System has 2 loops each controlled by its own stat and TRV. Have removed heads from trv's to see if they are stuck etc. Still no flow. I am assuming its an air problem but any advice would be appreciated.
Cheers
