WB Combi Boiler / Hard-Water Filter

stattman

Hi,

I have a Worcester-Bosch Cdi35 Combi Boiler which was fitted in the Autumn of 2005. Its been very reliable since its been installed, and has been maintained every year except the last one.

A friend recently had a new Vaillant boiler fitted and has had a filter attached to it. As I live in Leicester the area is a hard-water area and I am now wondering why this wasnt offered at the time.

The servicing has always been carried out by Worcester Bosch themselves so I'm not sure if this is a relantively new thing or not.

I'm due to have a new bathroom fitted which will mean draining the central heating system, and I was wondering if it advisable to have a certified installer come in to evaulate and install a filter? (I'm happy to do the right thing if its means more longevity of the boiler).

In the previous maintenance reports nothing has been reported.

So if you have any suggestions that would be greatly appreciated.

Many Thanks
Mark

The only guaranteed way to prevent scaling up is to have a proper water softener fitted.

All other 'in line' filters etc are very hit and miss.

One of Vaillant's selling points, when I used to fit them, was that you didn't need any filter for hard water and they gave a 5 year warranty on the plate HE, including against scale.

Don't know if that is still the case, as I have refused to fit them over the last few years.

Thanks for your advice. Probably the best thing to do is to get the work priced up and factored in.

'Scuse my curiosity but why?

Ah good point, I"m having a towel rail fitted and the old rad removed, and I suspect I don't have an isolation valve for the upstairs. It would make sense to try and get one fitted as part of the bathroom re-fit.

Ahh OK so what you want is a partial drain (rather than a full drain which is what your post suggested) to just below the level of the existing rad. Thats quite understandable. Don't fit isolating valves though.
