6 month old installation. Re ferb house. All pipework, rads changed and i mean every single pipe. New Platinum 40HE fitted. Customer had no hw. Called Engineer out today who found a blocked plate heat exchanger. He fitted a new one but told my customer that the system wasn't flushed correctly. I got an ear full from my customer.
I had used x300 and x100.
What causes the plate heat ex to block? I have had this a few times before but a 6 month old system can't be the cause.
