TRV's - does it matter what side of rad they are fitted to?

Andy From Sligo

Hello all - we have 6 Radiators upstairs in our house , 2 radiators out of the six have the TRV on the left hand side of the radiator. is there any right or wrong side to have TRV's fitted to on modern heating systems these days?

House was built in 2008 so I hardly think they have the heating set up in series (or whatever the technical term is) it must have parallel heating pipe system.

This is what I presume to be parallel and series piping:

not sure if left or right makes any diference.
whether its on the flow or return would

is there a frequency of practice (official or unofficial) where a plumber/heating engineer puts the flow always on the right say or do they just do it at whats convenient/easiest at the time?

I suppose I would find out (apart from ripping up the floorboards and tracing the pipes back to the boiler) by feeling the pipes leading to the lockshield or TRV and the one that gets hot first that would be the flow wouldnt it?

the_pen_turner

yes it would.
I don't know if there are rules on it but usually the flow is on the left

ah right - all the TRV's upstairs are on the right except for 2 :rolleyes: - still, they seem to work ok (apart from one small rad in the bathroom which is stone cold all the time - but thats another story)

Nearly all trvs can work on either pipe. So left or right makes no difference really. The small rad not working could be the valve stuck closed.

Try turning off all the other rads see if one in bathroom warms up

took the head off already on it and the valve pushes up and down with my thumb (what do they have in them a rubber washer is it inside these TRV's '?- if thats the case I suppose even though the valve moves freely up and down the washer could have swollen I suppose?)

I have this "setup" too ... the TRV was on the return side on two of the bedroom rads. They work find, balancing was alittle tricky but ok in the end.

in fact I found the towel rack radiator in the bathroom was throwing off the balancing quite alot and taking up all the flow. Once I restricted that right down , the other radiators heated right up.

I have a small rad on the landing, that seems to get extremely hot, tomorrow I will try turning down the lockshield valve and see what that does .. see if it gets that cold rad in the bathroom warm
