If this is true why limit the incoming pressure to 65psi? Why have some of us had leaks?
From my discussion with AS, AS does not consider this an issue!
Brycom please let us know what Dan says about the problem.
Well... here goes, mind you some of the conclusions I have here are not really based off my discussion with AS more me digesting this issue a bit more in my own head.
I (finally) called Dan today (have been very busy at work so today was my first chance)... I reminded him we had talked a few weeks back, and he remembered.
I mentioned this issue, my concerns about it, here is what he said.
Regarding water getting to hot hurting someone:
"This really can not be a problem b/c the gas or electric share the same ECO (emergency cut off switch) and the system can never reach a temp where it would hurt someone"
Regarding water getting to hot damaging plumbing b/c of loss of bubble:
"The pop value will handle any over pressurization issue before it damages plumbing."
Regarding bubble maintenance or need of expansion installation:
"Maintaining your bubble is a maintenance item"
Collimare I concur AS does not consider this an issue.
I was kind of hoping Dan would be aware (at least) that there are people out there with questions in and around this system, but he was not. I was figuring based on the size and nature of AS there was a good chance of this but no, and for me that fine I guess, let me explain..
For me, AS still has my business. I have worked for large software companies (vmware, apple, emc), each of them had quality products, systems in place to ensure quality was gained from real world customer issues, but that system took a while to get moving for a specific issue. An example is I was assigned a P0
(highest there is) bug for an issue the US Navy
was having, can you say big $$$ customer. I dropped everything, had it root caused and fixed in a week, but it still took a few months for the fix to make it into production code, and still a few more before the Navy got the fix. It was interesting to watch the *knowledge* of this issue make its way through the company (tech support, sales, other eng depts, managers, etc), it was a real issue, effected a large group of users beyond the Navy, and when it finally all came together I saw that knowledge of it was like many threads slowly merging, if that makes sense.
So, IMHO, it just has not been long enough, and I am sure there are some threads spawned at AS about this, sure there are AS people talking about it, but it has not come up company wide yet, the threads have not merged.
I would have hoped AS would have jumped on your issue to resolve it for YOU
, once presented the facts. Sigh...
And finally I can see an angle where one could say this is a design flaw in the water system itself (more of my digesting I mentioned above), should not the system have a proper expansion tank? My on demand home boiler does.
