Combi Boiler central heating excessive noise

[chrishob]

Hi,

I have a combi boiler installed,with only one radiator connected to the central heating .

I have bled the central heating through the rad and i have turned the pump speed down to minimum.

The problem i have is excessive water noise through the rad when the central heating is on,it sounds like running water rather than any banging sounds.Any ideas what it could be or how to rectify it.

Thanks Chris

Excessive turbulence due to only having one rad fitted?
