Highly advice:install / check your heating filtering system

Hello,

Got the boiler's heat exchange plate replaced last summer and installed a magnetic filter at the same time,after i saw the damage caused by water on the plate.

This week,it was time to open and check / clean the filter.
Shocked to see inside the level and amout of dirt and metalic particles attached to the magnets !!

The attached pictures are worth it to install if none present OR open & clean the filter at least every season summer / winter !

Wow - I got one installed this time last year, and promptly forgot about it...your photos make me think I should check it!

Did you experience any flow rate reductions due to this material?

Also, presume you had inhibitor in the system?

I installed a TF1 cyclone filter from Fernox yesterday.Our Worcester Regular boiler likely has had a lot of gunge pumped through over 10 years but it hasn't clogged or had its heat exchanger 'kebab' /overheat as the waterways inside are huge. Any combi though much more prone to clog with the tiny passages in the secondary exchanger. Fernox are doing a new filter out shortly the TF1 Omega and looks lovely. The tf1 cyclone also seems to work well on running the heating for 10mins yesterday it took out quite a lot of black gunge. Fernox filters also take only 30 seconds to clean and doesnt have to be opened. Just slide out the magnet open the lower valve and open the top outlet valve to flush the gunge out. Can top up the inhibitor through the top or the inlet valve too.
Anyone installing one be sure to have plenty of hacksaw blades as copper eats them and Irish 3/4 inch olives as the Fernox comes with metric 22mm olives.
Don't like the gauze in that filter if that clogs does it restrict the flow? If so it could take out the boiler. I know the Fernox ones have a 96% first pass and if full have no restriction.

Irregardless of water passage size, any heat exchanger will block. Putting a mag filter onto a dirty system is pointless. You will be cleaning the little magnet every day. Putting inhibitor into a dirty system is also pointless and will do more harm than good. The system should be powerflushed first, then fit the mag filter and then add inhibitor to the clean system.

I'm still surprised we don't use aluminium more for radiators...
