New boiler, pipes, dirty water in radiators

Canucklehead

Good afternoon: check the manufacturer's installation specs (you haven't said what boiler has been installed) as you could have trouble down the road i.e. from the state of the system fluid and the warranty requirements. I would recommend a magnetic filter if one hasn't been fitted already and flush the system properly. What was detailed in the quote in regard to system cleansing?

It is a Worcester Bosch 30CDI combi. Pipes in the screed are plastic, elsewhere they are copper. The quote was to replace the old boiler and install the new one, and replace pipes around the rooms (bungalow) with ones under the screed. I doubt there was an explicit statement of flushing the system properly though he claims the system was drained and the radiators emptied. Not being a heating expert I had no idea what the quote should say in detail. I assumed they are a reputable company. They have been going a long while.

He said that a power flush would cost ~£400, or something like that, and was not worth the cost. He did say they had put in a chemical mix "which will clean the radiators". Could this cause so much dirt to come lose, presumably from the insides of the radiators?

Lots of advice on the forum on what to look for in a heating quotation/specification as well as here. Btw...please don't assume that someone who has been in the heating business for yonks doesn't cut corners/bodge.

Worcester Bosch won't be keen on the current situation.

Thank you very much. I only found out that it had been commissioned by accident. And I have had no instruction from them, no safety warning etc. The person I deal with is one of the hardest people to deal with that I have ever met. He recently described a meeting between the two of us two weeks ago which never took place.

I expect the system was cleaned with F3 or x400, but dought very much that the rads were taken off and flushed. Doing just a chemical clean and draining off from a single point will not remove the all the sludge in the rads. Only a powerflush and will do this.
£400 is over the top for a powerflush, average price is £200- £300.
And most fitters will only add about £150 for a powerflush if fitting a new boiler at the same time.

Take a look on the Worcester site, to see if he is am accredited installer, if so complain the them, take sample of your water and get it tested.

Unfortunately he does not pop up when I search the WB site for accredited installers. I will photograph the water when I drain the next radiator, if only to use as evidence when I give a poor description of the work to the CheckATrade people.
