Freezing 3yr old son's bedroom HELP!

[Leo21]

I would love to see you sorting an oil twin vapour burner rayburn nouvelle in less than 3 hours on a standard service, or 3 days if you've not got a manual

I've had a look on other forums, and it's quite simple.

great, next time I am asked I will give them your number, there aren't that many out there (Aga trained or not ) that will go near them the powermax of range cookers, but a lot lot worse..................

Oil is for kids. Afaiac if you can do a 12000 service on ya corsa you can work on oil.

Heating runs on mobil 1 right ???

7am update, heating on for 1hr, 1-degree outside..............no improvement. rads 65-degree throughout house, problem 2 still at 50. Going to kick out theem with a mallet when I get back from work tonight

7:30am - 52 lounge, 55 bedrom, coming up but slowly as other rads in system start shutting down on thier TRVs as rooms reach temps...........downside of all this is I now have a boiler pressure of 2.7bar!!!!!!!!!1 up from 1bar cold. Clearly increasing pump speed to 3 with current lockshiled settings (most are throttles way down) is raising boiler pressure.......or coincidental problem with EV pressure (which you say I cannot touch evn thought shraeder valve can be seen at back / top of boiler).

Not sure how fast the boiler pressure came up this AM, will get wive to turn on heating from cold this afternoon and watch gauge for 10-min to see if it shoots up (indicating EV issues) or rises slowly over an hour, indicating lockshileds too far shut on too many rads issue

Next step - open lockshileds downstairs more to reduce system resistance and max boiler pressure on pump 3 setting, or just call out an engineer (I know!)

 

[Leo21]

The increase in pressure is not related to balancing system. Opening rads won't cure it!

smglasgow.

Please be aware of our swearing policy on this forum.

This is a friendly reminder of that policy.

Don't swear!

 

[Leo21]

Actually I said, if the case has to come off the boiler you can't do it.

Stand to be corrected here but, using a rubber or even a hide mallet wont have the effect of "Shocking" the pin free, needs to be something metallic.

I use a. Icily waited adjustable, a short sharp tap.

A small hammer will do if no adjustable spanner is available. lol

well. after a couple of days tapping the TRV in 3yr olds room, finally bot the bullet and replaced the TRV body completely with new unit. Pump speed 3. with the result .....................NO CHANGE! 55degree radiator temp at top compared with brother room at 65 degrees. Radiator no cold zones and 5 degree difference top to bottom, so wonder if the lockshield is restricted with gunk even thought the head is fully unscrewed. Back to drawing board for now I guess. Current thinking:

- replace loockshield;

if still restricted flow:

- flush radiator from hose - even thought convinced clean!

if still restricted flow:

- investigate blockage in pipework between brothers radiator and 3rd olds (all of 8 ft!)

if still restricted:

- replace pump.


if still restricted:

MOVE HOME!!!!!!!

Glad I dont do this for a living, like forensic science this lot.

10ft length of cable ? Sort of 5mm diameter cable used to hang net curtains and maybe a wet vac?

 

[smglasgow]

brainwave.........perhaps, just seen brothers hot rad - 65 top, 67inlet, 55 outlet (ideal 12 degrees temp drop) with lockshield at 2 turns from open. Problem rad is wide open on lockshield with inlet of 63 and outlet of 58 (5 degree drop) and top of rad at 58. Surley if I throttle down lockshield on this rad it will effectively reduce the speed with which water flows through the rad and therefore heat it up (paradoxically as I always thought the last in the line needed to be fully open)>

wrong time to test this as system now up to temp, but will throttle down by 50% and see how it looks tomorrow AM

Remove affected rad and fit length of copper between valves, see what temp you get on the pipe
If flow pipe, temp copper pipe and return all get to same hot temp, then rad is the problem
If no better, points to a restriction in flow/return pipe
