i asked about a few things earlier. this was something i tried to see what would happen. i set the t-stat to just enough to kick the system on. the system heated the house up to the set value and shut off. i checked the pressures and temp the pressure was kinda high like 22 psi, and the temp was up to around 150. i'm guessing it's the heat pump that is set to 130 cuz thats when you can feel the water circulate the system. it's set for a breaker shut off at 175. so maybe nothing is wrong because before i'd always turn the t-stat to an un realistic setting like 85 degrees instead of 68 where i want it set. i'm not noticing any more pressure relief valve burps. i'll bring in a professional if suggested because i don't understand the system. especially bleeding of excess pressures.

    It does not matter if you set it for 100 or 70, a call for heat is on and off is off. Only difference is length of call for heat. As for the ex tank, hot water expands into the tank, thus the top is hot. You would need to isolate it & pull it to check it properly. Excess pressures are not bled off...air is bled out. If no air and too much pressure, let some water out through the purge valve or boiler drain. Set to 12-15# cold for 1-2 story home.
