I have a problem where the last 6 radiators on my property

Customer Question

Hi, I have a problem where the last 6 radiators on my property do not get too hot, I ahve tried balancing etc, I have 22 large cast iron radiators and the boiler is relatively modern and flow and return does get up to correct temperature. Is this likely to be a central heating pump problem
JA: How long has this been going on? And how severe is the problem?
Customer: AS we are just in the heating season, I would say for a few weeks, if I turn down a number of rads via the TRV then the rads get hot
JA: Do you plan on doing the work yourself?
Customer: I have not decided at this point
JA: Anything else we should know to help you best?
Customer: Nope

Do the cooler radiators get really hot when you shut the others down?

This should rule out a partial blockage or restriction

If I turn off other rads I can get them hot.

ok thats good.

if you have done this before and balanced the system but you still get cold sections of radiators and pipework then try swapping your pump as it may not be running as fast as it should be
