Hi All
With Fernox F3 in the system the banging stopped, with it removed the banging stated again and before my previous thread got locked someone mentioned scale in the heat exchanger. I live in a relatively soft water area but I had to drain the system a while ago.
I was putting the floor boards back down in one of the bedrooms after re-routing the mains cable for the shower when I herd two hissing sounds. Oh yes, a screw in to each of the main pipes from the boiler.
I cut a small section out of each pipe and then I joined them together with a straight coupler ring. Unfortunately, I did not put in any inhibitor.
I checked on the web for a boiler descaler and found the Fernox DS40, which is not cheap and the Sentinel X200 Boiler Descaler at less the 20 quid. The X200 can be left in the system and should continue working for the next few years. So that is what I was going to use.
As it happened my plumber called round the next morning. To save time I had already got the front cover off for ready when he could get round. It only took him a couple of minutes to work out that it was scale in the heat exchanger.
Replacing it would cost £200 and that is £200 I do not have, so I have used the X200. Even if it delays the HX being replaced it will give me time to sort out some money.
I turned off all the radiators except the one closest to the boiler, drained off some water and put in the X200. I then topped up the water and switched on the boiler. I let the system run with just the one radiator, in the hope that a more concentrated amount would remove the scale a bit quicker. I was concerned that I might do more harm then good so after a couple of hours I opened the valves on all the other radiators.
I now have a working system, no banging and DHW at 50 degrees.
However, I have no idea how well the heat exchanger is working, so I was hoping to get some feedback from all of you.
On a similar system, Baxi Platinum HE, what does the temperature gauge go up to with the DHW set for 50. Mine is going up to about 86.
