Radiator not heating

Luckycharms_74

Hi All

I recently had to get the pump replaced on the back boiler (noise from the old one). Whilst the plumber was out I asked him to balance the radiators in the house. The main reason was one of the bedroom radiators was not getting hot, the other 4 radiators upstairs were roasting with heat. He shut off 2 radiators in the spare bedrooms but still no joy.
He decided to replace the suspect radiator with a double one, but it's still the same. He now says he will have to replace pipes running from the hot press to the suspect radiator. He mentioned something about faulty return or flow ?. The heating system is about 15+ years old but the radiators were all replaced about 5 years ago. I read somewhere else about "Power Flushing" heating systems for sludge and inefficient radiators ?
Anyone out there ever come across this problem.

i would try cleaning out the system first, it sounds like the system is blocked with sludge

@ the OP:

Hopefully you haven't payed the dud.
Get a heating engineer in. The original tool box owner you had in doesn't know what CH "balancing" means - as far as I can read from your posting.

I should have phrased it better in my OP. He shut off 2 radiators and balanced the remaining radiators. With regard to the heating engineer, I assume they are easy to get hold of. ?

Could be that your pump isnt powerfull enough. Is it the same power as your old one?

I assume so as well. They are found in the golden/yellow pages offering their help.

This is often the case especially with solid fuel systems. Basically, poorly circulation, under-sized pumps, etc. can cause the system to overheat and this leads to the system pitching over the ovsp. This gathers fresh oxygen which reacts with the uncoated steel on the inside of your radiators and the steel within your solid fuel boiler. The oxygenation by-product is tiny particles of metal floating around the system and eventually settles in the bottom of radiators.

The only way to properly remove it is to Powerflush the system.

You can test the system for sludge content with a TDS meter (Total Disolved Solids Meter).
