Downstairs rads not working

Glebee

Hi guys,

Anybody able to point me in the right direction. Down stairs radiators are not coming on. Fired up heating system for the first time in a while this evening. Upstairs is fine. Single zone house working from an oil fired
boiler. Any advice appreciated.

If there are no zone valves on the system check that the pump is running.

Had a go at that and turned off all upstairs rads. No luck but now outside boiler will start up but will cut off after a bit.

open back up rad valves/

it could be that the pump is stook and only gravity feed to upstairs.open the vent on pump in boiler house and release the see if it is working ok . you should be able to feel or hear circulating.

or do you know if the system is sealed.a pressure gauge and expansion vessell and system low. poss but i would say stick to the pump issue.

try the pump after opening the rad valves and lets know how you got on.the vent is on the face of the pump like a 5pence piece with a large flat head screw.turn to left to release open maybe stuck.if not id say new pump.

Yes. Boiler heats all. Can't locate this pump. Is it part of boiler?

Glebee, it looks like this

But if you touch it before morning it will scald you, please leave the system to cool down.

that thing in the middle of the face of the pump reflects my description ...well done.

Cheers for help guys. Will leave it till tomorrow before I look at it.

I have searched high and low for this pump but cannot find it. Could it be that pump is part of the boiler. Its a Grant type external module 110/140.

Its hardly in the attic is it??? Sorry guys but my plumbing skills are limited
to turning on and off a tap.

It will be in the boiler case on the flue side.

Found it ok guys. Appears to be working when I turn on system. cant get to face of unit to open as its fitted towards the bloody back wall of boiler. A well, I think ill just have to get someone into look at it.
Thanks for help guys

Solved. Two switches at the hot press were not turned on. No idea how
they got turned off. These switches seem to control two "Myson Power Extra" units behind the hot press. Anyway when turned on, rads working downstairs. Thanks for all you input guys. :)

I am having the exact same problem, i dont think the pump is working but the face side is facing the back wall, What were the switches in the hot press that you switched.

A similar question lads/lassies.

I have one rad not working downstairs (it is a single rad). Have tried bleeding it and turning off all other rads in the house. Pipe coming up out of the floor to the rad is warm.

Thanks in advance.
