Have a Buderus 2 condensing gas boilers Model GB-142 Logamax Plus that I need some help with.
Went to clean out the condensate tank at the left rear of the boiler, and it was pretty full of a grey mud like material. Removed and cleaned the tank. Took the bottom cover plate off after undoing the spring snap clips and just about had to pry it loose. Well, I did have to pry the cover enough to get the top portion to come loose, then carefully get the rest off. The gasket/seal seems to stay with the boiler section except where it pulled free at the back and bottom right corner. The lid was completely encrusted with white and grey buildup especially where the condensate would flow through the hole at the bottom left. The hole was completely jammed and nothing could get out to the 'holding' tank. I chopped away at it and got it open and almost all the gunk off most of the lid. I did the same to the flat plate between the tubes with coils/fins and tried to wire brush off the coils mostly of calcium? deposits. Put her back together and it's running.
My questions are:
1). soft water- the installer said we could NOT use our softened water so the plumed it with the high iron/calcium water. It looks like the hard water is killing the boiler fins/coils everything it comes in contact with?!
Is there something to use, a spray or chemical to dissolve this hardness from the fins? It's like concrete! Wire brush isn't cutting it.
2). Is the silicone like gasket supposed to be replaced whenever one removes the cover to clean the boiler fins, etc?
3). How often do these boilers need to be taken apart and cleaned, and does the condensate holding tank often jam up with the lava like mud? Is this just a byproduct of the combustion process?
4). If I had to, can I buy just the outer door cover that has the holding tank orifice, or am I screwed if the gasket sealing flange gets chipped and the seal leaks?
Thanks for any help, suggestions, etc.
