Not all Rads getting hot

[deden56]

The TRV's only have one arrow and the 2 that are wronrg point into the rad but they are on the return side.

New Y plan in airing cupboard with 3 way port.TRV with arrow pointing in which is at return end.If you look back you will see old layout under bath.

The TRV's only have one arrow and the 2 that are wrong point into the rad but they are on the return side.

Instead of moving it to the other end, the TRV just needs to be turned on its side, swapping over the inlet and outlet. Having the control horizontal is theoretically better as it does not get influenced by the heat rising from the pipe.

Alternatively replace them with modern bi-directional TRVs and keep them on the same end with the head vertical.

as a long shot I checked the direction arrow for flow on the C/H pump it was ok

 

[deden56]

I have had a power flush on the advise of a plumber who did the Y plan with no change still have poor circulation.I have a plan of how it is piped and what the plumber who flushed it said.It's an excel file is it possible to upload it to here?

 

[deden56]

I can send it in an email If anyone wants to view it.

Have sent you the plan.If the heat exchanger is blocked is it a new one or can it be cleaned.It's a Glow worm Flexicom hx 24kw.I know it's an aluminium exchanger.

so many things to check, do they get warm upstairs and not downstairs? Is it that there are some up and some down?? I'd be looking at the pump, whether the by-pass is set correctly or if there's any blockages

 

[deden56]

only certain ones get hot upstairs & down

I can send you a plan of system the way it is piped if you give me your email address

 

[stevetheplumber]

if it didnt work before it sounds like you have a problem in the basic design of your system you need two motorised valves and probably a balancing valve on the cylinder get the controls sorted then you can repipe properly sorry failure to read complete thread controls look fine now
