Hello Folks.
Looking for some extra advice regarding our new CH System. We recently replaced our Old Electric System with a Worcester Greenstar Camray Condensing External Boiler (Oil) which has been connected to a new Megaflow Systemfit within the house. We had some problems after installation which we posted on this site, and a very helpful guy gave us the no. for a Aberdeen based plumber. We did contact him, but he never got back to us, so finally got hold of another one, who has spent the last 2 days checking over every part of our system: -
All Megaflo System working as required (plenty of hot water) including motorised valves, pump, pressure vessel etc (and plenty of hot water).
All pipework in correct places (double checked this by swapping pipes just in case)
Whole System was Power Flushed this morning for 5 Hours.
Problems still arising: -
No return flow on rads. Flow pipe coming in so boiling hot, no circulation.
Have tried heating rads one by one. This works and all rads get roasting, but turn on more and the heat dissappers, return pipes still cold. Have tried balancing to no avail. The plumber has said there must be a blockage somewhere in the pipework, but where, we have no idea. We had tried power flushing but it has not shifted the blockage. Is there anything else we can try, as we really don't want to have to go change all the pipework. Is there a different stronger chemical we can try? Any ideas would be helpful and much appreciated.
