@ February 26, 2013 11:32 AM in Thunderous GV90+Is possible but if a cycle ended before the tstat satisfied or the boiler got up to temp. the control should have flashed and error code. The only other thing I can think of that may cause this noise is a bad pressure reducing valve on the water main coming into the house. They have been known to cause quite a racket when they hammer.
@ February 25, 2013 4:07 PM in Thunderous GV90+You said you ran downstairs 10 seconds after the "thunderous noise" and found the boiler HAD JUST FINISHED a cycle. Hard to have a delayed ignition at the end of a cycle. A hot surface igniter will either produce heat or it won't. If it doesn't produce heat it won't ignite the gas, not early or delayed. Those igniters are right next to the burner. Its hard to believe your having a delayed ignition with a HSI. On the other hand in that same post you said one zone was calling and one had just shut off. I would attempt to recreate the noisy by opening and shutting zone valves by the tstats.

@ February 25, 2013 3:52 PM in Hot Water Heat with cold rooms furthest from the boilerHow your measuring your baseboard.44" long OK. But 2" high x 6" wide? Anyway you basically have a 4 foot baseboards which ain't gonna cut it. Plus I doubt that they are pipe directly back to the boiler. Most likely in series if on the 2nd floor. I would raise the boiler temp to 180* f.
@ February 24, 2013 12:37 PM in Thunderous GV90+Says its a zone valve issue. Your noy going to have a delayed ing. at the end of the cycle.
@ February 19, 2013 7:47 PM in Yet another boiler selection question TT with built in DHW or indirect?A smart 30 and the tt60. The exe. only has a 14 gal tank. The smart 40 may be just a little big for the tt60.
@ February 19, 2013 7:41 PM in heat pump t-statA real nice two wire tstat that will do what you need. Mod. tp-prh01-a.
@ February 18, 2013 7:28 PM in Compressor Burn outWe are talking what 18oz of refrigerant? Put nice clean freon in and a clean up dryer on the suction side. Also put a hh dryer on the liquid side and sleep easy my friend.
@ February 18, 2013 7:22 PM in Thunderous GV90+Sold on delayed ignition. That happens more with spark igniters then HSI.If your using honeywell zone vavles and have a series 100 pump and a short baseboard run that rubber ball inside the valve will bounce like crazy and make a racket.
@ February 18, 2013 7:08 PM in Intermitted gas furnance problemFurnace has a molded plug on the blower compartment shelf you can try cutting that out and wire nutting the wires togeather. Sounds like you have replaced everthing but the wiring harness.
@ February 18, 2013 7:02 PM in bryant gas furnace, no heat..Just don't know why I can't get it my own self. Went to lit. then prod data put in 350 and only mva's come up.
@ February 18, 2013 6:56 PM in bryant gas furnace, no heat..And still will only show me 350mva's
@ February 18, 2013 6:49 PM in Steam Pipe Coils and Sprinkler HeadsYou should pose that question of what temp to go up too to the Fire Marshal. Also I think thats the first time I used the word to or too more then two times in a sentence.
@ February 18, 2013 6:42 PM in What should the proper fpm velocity be for a furnace in aYour at less then .05 SP you should be able to go up to 900 fpm with no real noise.
@ February 18, 2013 6:37 PM in bryant gas furnace, no heat..Didn't see and Bryant 350aav. There is a 350mav which is a 90%er. Sounds like you need and inducer motor or a circuit board.
@ February 18, 2013 6:32 PM in bryant gas furnace, no heat..That furnace should have a two diget code. The first number determined by the short flashes and the second number by the long flashes. So one long flash followed by 3 short flashes = error code 13
@ February 18, 2013 6:27 PM in A math problem :)The only sensible thing too do with a water thats not working well is replace it.
@ February 3, 2013 8:41 PM in Triangle tube prestige mod con?I would primary secondary that for sure.
