RADIATORS STONE COLD / HEATED TOWL RAIL BOILING?

by **mdolan** » Mon Dec 29, 2008 3:40 pm

hI
i have just had a new bolier fitted a combi. The hot water is fine but there is no heat out of any of the radiators. The heated towl-rail which is above the bolier is boiling. The pipes leading into my daughters room under the floor boards are hot and a few feet away the radiator is stone cold. I have bleed them flushed out all the water from the house and even taken the radiators of the walls and flushed water through them.

I have also put a sludge remover in 6 weeks ago and nothing?

I have no idea what to do. I lifted the floorboards outside the toilet and the pipes are freezing. Even downstairs pipes are freezing.

Please help? :(

If you have TRV's check the pins move freely.

No luck - check pump

The TRV are fine. There is water ib the radiators but freezing. Where do i check the pump? Would this be faulty already?

TRV look fine. Water is coming out rad but cold. Both the pipes leading into rad are stone cold?

Vizo Condensing Combi Boiler VIZO24 White

Boiler pilot light is going on and off every copule of minutes. This is probabaly becuase the only thing heating up is the Towel Rail. Then it goes off and that is it?
When we put on the hot water for a bath is fires up until the bath is full.

That points to the diverter valve then.
Check the fault diagnosis in the MI + follow to prove.

Thanks for the reply. Where is the divertor valve and what is MI?

The diverter is in the boiler.
MI = Manufacture's Instructions.

Steve,
I have had British Gas in yesterday. They have told me i have a blockage and that it would cost for a power flush from them £700.00.

THE BOILER IS FINE.

Would this be the answer. I have checked online and HSS can give this power flush to me for £67.00 for a day.

I am still getting hot water and Towel rail heating. If the powerflush does not work what is the general amount ( COST) for replacing all the pipes?

thanks.

Don't pay £700 WTF

Find a strong magnet and run it slowly around your pipes to see where it sticks.
But wait a min, you say you just had it fitted - get the installer back pronto.

Steve,
thanks for the reply. The guy who installed has gone underground,i cannot get him at all. I really do not know what to do now.

I don't even have his corgi number either, never filled in the forms.

He was only paid to put the bolier in but took an exra £100.00 to check the pipes but whatever he done did not help.

The problem is there was no bolier in the house for 4 years when i moved in?

"i have just had a new bolier fitted a combi"

You don't need any help from here - you need the installer back and soon!

I sent this before your above post was approved. I still stand by it but I see now you say he's disappeared.

If you don't have his CORGI reg or any paperwork theres trouble brewing. Do you even have a name? If so go to Trading Standards without delay. They have to find where this guy stables his horse. He is a danger to the public IMHO.

"I have had British Gas in yesterday. They have told me i have a blockage and that it would cost for a power flush from them £700.00."

Ha Ha. Standard BG solution to every problem - sell a power flush! What evidence do they have that it's a blockage? Get a proper local, recommended heating engineer in to have a look and advise you.

hi there,in the past ive come across new installs that have become reverse installs.if u say there was no boiler there for 4 years do u know the previous set up. the new flow may be the previous return! are the trvs bi flow,if not the rads will not work or there may be a check valve under the floor or on the pipework,this may be the blockage bg are talking about in which case no powerflush will clear it and the power of the flush may damage the pipework if the flow is impeded. hope this helps
