how much is this pump likely to cost!!!!!! :cry: also is the cause of the water running cold all of a sudden due to the stat temp being reached / and then allowing only cold through until the temp drops again? i am curious to know why it is doing it???!!

ah i see, it's probably a common occurence with combis then in hard water areas (most of england then)! :( what pump would i need to hire to try?....

it shouldn't though as the temp was set at 60 on the stat :( is it because the scale over time has added up little by little due to the fresh water going in.

Thanks for your help, So basically the inside of my cold pipe (h/w outlet pipe) in the heat exchanger is scaled up :( I don't know why though as the temperature is not over 60 :( There's anbsolutely nothing i can do....??

thanks for helping me. i am glad the heating side will not be affected, as you said i only have 1 heat exchanger then i thought it being scaled would affect both h/w and heating. i see boiler de-scalers/silencers (for scaled up heat exchangers) in shops, are these no good then?

Thanks for your reply I have seen some scale redcuers, look like a tubr that you fit (push fit or compression fit) in line on the cold supply to the boiler. I see, so is there no way I could add a de-scaler to the system myself then to try and cure it? Is this scale likely to affect...

Hello,I hope someone can offer me some advice please? I have a combination boiler. It id a Worcester 28i junior. I have the manual here with me. Anyway the problem is, when hot water is on,it's great, very hot, not too long to wait, and then all of a sudden, goes cold (like normal cold...
