Hi guy,
I've had the dhw heat exchanger on my boiler changed twice within a year and a half. The gas engineer who fixed it recommended a power flush.
I had quotes from several plumbers. One plumber(ex british gas engineer) said that a chemical flush would be enough and that a powerflush didn't clean the boiler and heat exchanger. When I mentionned that to another plumber he said that it was wrong and that powerflushing did clean the heat exchanger. He said he connects his Kamco machine directly on the boiler pump and that the chemicals circulate through the boiler and heat exchangers.
Who do I believe? And what is best?
By the way the guy who recommended the chemical flush said that powerflushing often opens a can of worms as it can weaken joints in rads and piping.
Any advice on the subject would be greatly appreciated.
