Just a quick question

[bewildered_englishman]

I have what seems to be a common problem judging by the frequency of posts on the subject.

Upstairs radiators (4) are hot, downstairs (4) are cold, except for towel rail in downstairs bathroom which i assume is a "bypass".

Problem has come on gradually, no alterations have been made to system.

Boiler is Potterton, Fan Assisted Balanced Flue Gas Boiler located upstairs, as is the water pump and tank.

I am assuming that there is a build up of sludge etc downstairs and the system needs a clean out, but before I go to the expense, is there any significance of the Bathroom towel rail being hot?

Any info would be gratefully recieved.

Towel rail is probably on your hot water circuit and therefore independant of other rads.

Bleed the pump first and then go down the sludge route.
