    A few weeks back, I posted on here with problems re hw running hot and cold, plus F14 on my GW 30 cxi. Thanks to all on here, I managed to take the plate he out of the back of the boiler without any dismantling, as the boiler is on a frame in the loft.

    Anyhow, the old HE was blocked with rust particles. I have thoroughly cleaned and flushed system, and added a Boiler Buddy. The new HE is in, and the boiler works perfectly. Is it possible to clean the old HE, as it seems a shame to bin it. I would like to keep it for a spare.

    How do I clean it, and what cleaning agents will remove the rusty particles from inside? Many thanks.

    Most heating engineers can clean plate HE's using a Power Flush machine and special adapters that fit to the plate ;)

    Or a ten bob bottle of white vinager and that will clean it overnight give it a rinse in morning then soak it again for a couple of hours . Leaves them like new

    Kamco FX2 is very good, cleans both sides. Do one side at a time; pour in neat and then pour hot water in the other side (works better when hot), leave for 10-15 minutes, rinse it out and repeat for the other side. Flush it out with cold water first.

    This method was recommended to me by an engineer on here ;) works brilliantly.
