Blocked heat transfer plate

[andyperkins]

I have a baxi HE combi, it is less than 12 months old. The heat exchange plate has blocked up for the second time in a couple of weeks. Although the system was power washed before installation, i have been told that the only solution is to replace all my radiators.

Is there a cheaper option than this?

Thanks for any advice

had one similarabout 4 yr ago. after 18 month i changed the rads and no problems since.

if you are going to change the radiators i would suggest putting in a magnaclean or boiler buddy, to prevent any problems later on

Sounds like it wasn't flushed properly You don't need to replace your radiators fella. Just get a competent guy to flush correctly, the installer didn't do a good job by the sounds of it... You need an RGI to check your system water, simple test .... Then fit a magnaclean on the return

can you not fit an inline filter on the return pipe? this would collect all the crud a stop valve either side would allow for regular cleaning

Fit a magnaclean filter on the return.

if the rads are so far gone internally i would recommend replacement.

Fit a magnaclean filter on the return.

yes they are good but they won't catch everything. I was thinking of a simple gauze type filter as they only take up a few inches. either would be better than nothing.

Baxi has a filter already in its return.
Something does not sound right if its been flushed properly then it should not be blocking.
As oppossed to changing rads take them off and flush them properly with a hose outside, this is far mor affective than any power flush

Has the valve with the built in filter been fitted on the return to the boiler? Is it being cleaned regularly?

Has the filling loop been fitted to the return?

Anyone fitting a Magnaclean properly will add a gauze filter washer to the outlet to trap non magnetic bits of dirt.

Tony,

While this is true, getting them can be a little harder than it sounds when your local merchant doesn't appear to stock them anymore., i heard BES sell them but can never find them, where do you get yours from Tony

BES and then I scatter them around a bit to make it easier to find one.

Some washing machine shops have them too.

Thanks Tony, I found them but no 28mm ones? I will keep looking for them

Thanks Again

I dont ever remember seeing a 28 mm filter washer.

Yet again, I do have to say that Chris Adey should be getting them made up and supplied with his products!
