Heating problem

[mrP(Boonen)VT]

Sorry this is not cycling related, but anyone out there have a clue why my downstairs radiators are remaining stone cold, yet the upstairs ones and hot water is boiling?

I have bled all the radiators, drained the system and refilled with a flushing agent, and replaced the pump, all to no avail.

Grateful for any advice.

I reckon yer pump's jammed .

As fer the heating, no idea .

Seriously, it'll be the pump 9 times out of 10 methinks

(sound of sucking air through teeth) that'll cost yer guv.

If the pump has isolation valves either side it's a pretty straightforward job.

Right try this; open up both valves to all the cold radiators, turn off all but one of the hot radiators, turn the room thermostat up as high as it will go. Give it say half an hour. If it does work then start to turn down all the hot rads and open up the closed ones; it's know as "balancing" the system. Sometimes when work is carried out it does upset the balancing and you get a sub-circuit develope.

Also, when you changed the system pump did you put in the correct way round?

Best of luck.
