Rad won't work

[billybongo]

A friend had a combi boiler put in to replace a back boiler , ever since a rad in her conservatory hasn't worked . If you shut others down it works so it's not blocked , the pipework goes into floor and pops up into rad which is not unusual , a gas engineer said to reroute at higher level ie take out of floor but would this be any better? I can't understand why it won't circulate as combo is higher pressure than previous system , any ideas folks howy

Sounds like a balancing problem

Cheers Glenno will have a go and see what happens howy

first thing to do is balance the heating system correctly as glenno suggested.

I'm sure balancing rad's is becoming a dieing art, the number of newish systems I go to where all the lockshields are wide open is unbelivable, the folk wonder why all the rads don't work and the boiler doesn't condense very well.

It is such a pain though, I know we should all do it, but how boring is it.

problem ive had before if not a balancing problem, flow and return have been linked together some where airing cupboard or old rad has been linked 1 rad in system doesnt get hot why i dont know but worth a look if balancing dont work

Just because when you turn other rads off, the conservatory rad works, doesn't mean there is no blockage! If a pipe to it, or rad valve is nearly blocked fully & you only have that rad on, it may work well (perhaps not so much in winter). A bit of dirt when new boiler fitted could have blocked pipe or rad valve, or if a Trv fitted, it could be jammed nearly off inside it.

Best , that is all feasable as i asked her if it was powerflushed on boiler change and she didnt know as she wasnt there most of the time , i will as her when i see her if she has bill for job which might list a powerflush , i am just trying to aviod getting to involved myself , have you heard of " love jobs " not good .

The guy that did the instal should really have helped sort it. Most you want to do, if balancing doesn't work miracles, is open each valve of the rad, one at a time & run it into a hose or bucket & perhaps rad taken off first & flushed. Needs two people to make it easier. Hope she gives you plenty of love if it works! :smile:

Have you checked the pin in the trv comes up correctly? I've seen them stick a little bit so hardly anything comes through.

I couldn't agree more Roger, I was called by a colleague to Powerflush a property, when I had a look at the system I found the problem rad (not heating up) and identified the problem as the fact that the system wasnt balanced. I discretely balanced the system and to the installer's credit he paid me for three hours labour out of sheer embarrasment.
