duh .. whoops ... pressure cycle graph

Whoops .. this is what it looks like when you turn the heat up to warm up the bedrooms for the kiddies and then go out to a birthday party forgetting to turn it down....



A few comments .. I flipped over the vents on the first floor rads (4 rads) to keep the heat away from the t-stat .. almost all rads (6 of 10) that is being depicted have TRVs on them.



the TRvs seemed to do their job as only 1 of the 6 rads had significantly overheated (80degF) the room (happens to also be the only blown cellulose insulated room) and even at that temp, the TRV may not have closed .. i probably just need to adjust that TRV (or my 3y.o. daughter cranked it up, even though I asked her not too touch). all other TRVs held temp to where they were expected to hold (70ish degF)



the red line is Flue Gas Temp. The Dark Blue line is boiler room temp. other lines are left to ones imagination.



i'm not sure what happened at 19:35 or at 20:35 .. (those wider gaps) it seems the boiler stayed on a little while longer during those 2 gaps... perhaps 1 ro 2 TRVs opened up and let in some more steam.



also please note that my v-stat is set at c.o 6oz/c.i. 4oz which roughly translates to c.o.8oz/fire on 0oz. in actual real-world operation.



so that you don't have to go bleary eyed trying to count .. it looks like between 18:40 and 19:40 there were 30 cycles .. and same between 19:40 and 20:40 .. so that must be roughly 1min on 1min off.

dam cool

Well, I think those results are just so dam cool.  I appreciate your ability to take raw data and turn it into eye candy.  It is so nice to see examples of what is going on inside a system.  This helps us all to visualize our own systems.  You must have a strong computer background.
