Hi,
Firstly appologies if this ends up a little long!
I have a Worcester Bosh 24ri boiler which is connected to an Albion 210litre direct thermal store. They were both fitted around 5 years ago, and today I had to have my second heat exchanger fitted to the boiler, so I am getting through them at a rate of 1 every 2 and a half years.....pricey.
My concern is, in another 2.5 years I will be in the same place again so am really looking for any advice on where I could look to find the problem. Here is some background.
About half of the pipework is original (could be anything up to 30-40 years old) the rest has been fitted within the last 5 years. Most of the radiators are also 5 years or less old. The thermal store is also 5 years old and the whole lot has 12 litres of fernox MB1 in it as inhibitor.
The first heat exchanger was very corroded when removed. The second however did not look half as bad, but was cracked on the outside and when the boiler came on to anything above minimum it started banging and crashing about, hense the second replacement.
All is working fine now, but I really want to find the cause so I dont have the same thing happen again.
Incidentally, I have also had 2 radiators and a towel rail fail from small rust holes breaking through, one of the rads and the towel rail where under 5 years old.
Any help with this would be greatly appreciated, I am fairly sure I have enough inhibitor in it, and it has been suggested the boiler should not have died in 2.5 years even if the inhibitor was low.
Many thanks.
