System 2000 EK1 Sanity Check... new homeowner
Hi everyone. My wife and I just purchased our first home in NJ which is heated by a Sys 2000 EK1 (2009 install). We are actually like 30 minutes from Energy Kinetics themselves.
I have done some reading on the system theory of operation and have observed a few full domestic hw heating calls. Could be my imagination but I think there might be some weirdness going on.
When the tank aquastat starts a hw call, the correct light comes on, circulator light illuminates, burner starts. Once the bar lights on the manager get to a certain level the light on the right hand side illuminates indicating the hw call is being answered. All seems correct up till now.
However both the output and input temps (dial and bar gauge) on the boiler side seem to rise pretty rapidly and eventually hit what I imagine is the high temp cutoff prior to the hw call being satisfied. Burner turns off for a few minutes, circulator stays on, and both the call and answer hw call lights stay on. At this point the domestic hw line out of the PHE is pretty damn hot. Hard to hold my hand on. While the line into the PHE is rather tepid.
The boiler will go through this a few more times before finally having the tank aquastat say everything is up to temp and turning the call light off.
Is this indicative of the PHE being blocked up on the domestic side? Something else perhaps?
