Hot flow and return pipes, hot upstairs rad but cold rads downstairs

Will do.



No worries I appreciate your help on this anyway, I'll update what it was once we've had it looked at.

Thanks again

That would be awesome mate. It’s always nice to get some feedback. It’s easy to forget us once it’s been fixed. UNTIL NEXT TIME

if it was just one or two i could see maybe a blockage but not all of them, i would say boiler is at fault

I am hoping that is the case, shelled out a lot of money for it and don't want to spend even more on additional work!

I would put money on it that it is diagnosed within 15 minutes

easy way to tell if its blocked but requires removal of a rad

remove a rad and test if you have water coming out of each valve from the rad you removed if you have its not blocked

Too right, will definitely update as I know how frustrating it is when you find a forum post with your problem and the OP never actually updates with what the solution was!

Be surprised if it is zoned then. But stranger things have happened.

Pretty sure it isn't from memory. They mentioned possible zoning if wanted but we chose to keep it simple. Also, only one thermostat was given to us.

All goes into the mixer mate. Always worth pointing out.

Most of the new valiant boilers you can on the boiler Display give so many KW to heating and hot water just check this . if the heating has not been used in summer most times the pump gets stuck free this up with big screwdriver I have also seen the nut behind the chrome screw on pump turn but the impeller stays put? As with Most of the new Boilers Valiant. Glow- worm. Worchester 30 CDI you can Map the Pump you should look at this as well . I think you should be ok if you are only touching the wet side of system To put it another way if AAV went in boiler and water flooding every were and in order to stop this you could turn off isolation valves I know what I would do
