Cold Radiators

[vishal]

My ga bill for the quarter was £200 because the heaters are on 12 hours a day.

My bolier is brand new but my radiators are old and the tops are hot but the bottom are cold.

I have a conventional system with a small tank in the loft.

What can I do to try and improve the efficiency of the radiatos without having to reove the radiators.

I was thinking of some sort of solution to put in the radiators? What's the best stuff and any other suggestions?

Thanks
Sunil

seems the plumber who installed ur new boiler did not flush ur existing system.
thats not good fir ur new boiler !

if u have a problem with all the rads to that extent i would be considering a power flush. £300 ? from a local plumber/heating person.

basically ur rads are not hot at the bottom cos they are full of corrosion/debri/sludge etc.
