Shocking Fault with Combi Boiler - No Hot water - Potential Quick Easy Fix

Faulty Combi Boiler resulting in No Hot water or Tepid Hot water. The cause was a Blocked Heat Exchanger. Once the Heat Exchanger had been removed, I was able to flush it out to see what was causing the issue. The amount of Debris causing the blockage was Shocking. The curse of the New Build home strikes again. Lack of care and attention when the boiler was originally installed was clearly the cause on this occasion.

Thanks. Might try this myself.
That crap won't block the bath if you fill it up and let gravity flush it out.

Which tool do you use to take the heat exchanger out? Thanks

It's the same issue I have with my boiler right now. Rads are firing up fine but only getting luke warm water. I put it down to the diverter valve as the heating is coming on even with the thermostat off. Don't suppose you have any ideas?
