@ January 18, 2012 10:48 PM in Low Delta T between boiler Supply and ReturnLook at some of the recent posts here on the main wall.Your problem has been discussed at length, and may save some time.Check out the post about the buffer tank.

@ January 17, 2012 10:00 PM in Pure Pro Boiler Furnace malfunctioning again?Get the information off the circulators, and any of the other components that have make or model #'s on them, and you can get the literature online.

@ January 17, 2012 9:43 PM in Pure Pro Boiler Furnace malfunctioning again?You should have documentation for everything installed with the system. I believe this is the manual for your boiler http://trioboiler.com/pdf/PurePro_Boiler_10-1-11_Manual.pdf
@ January 17, 2012 9:02 PM in Pure Pro Boiler Furnace malfunctioning again?Where's the bypass for that low mass boiler? Oh boy.....If all else fails, read the directions.That's not directed at the poster,just the installation.
@ January 15, 2012 5:19 PM in water heater vs tanklessThen what would the stand-by loss be of a tankless, because that is used for determining the energy factor of a conventional tank water heater. There is no consideration for different animals, and it may take a book to properly determine the difference in efficiency from one to another.They take like animals and score them based on their characteristics.I didn't make that up,or make the rules. That's just how they do it.
@ January 15, 2012 4:22 PM in water heater vs tanklessYou can't use energy factor unless you are comparing the same animals.They can't be tested the same way, so it's like comparing a water heater to a washing machine.
@ January 15, 2012 4:15 PM in Hot Water boiler-with old cast iron radiatorsyou re-filled the system, did you bleed from the 2nd floor first?

@ January 14, 2012 12:47 PM in I am stumped....Start from square one. You seem to be chasing the effect.Look at the system as it is now, and verify it has everything it should have. Then ask yourself, what would be the affect of one of the components not working correctly. Take the mixing valve out of the equation, for the time being. It can't add cold water to the system while in re-circ only anyway,only on a pressure drop from a fixture being used.
@ January 13, 2012 3:32 PM in I am stumped....If you went to an apartment and ran the hot water,then take a reading with an IR thermometer on the hot side of the valve, then ran the hot in an adjacent apartment and saw a rapid change in temperature, that would probably indicate a cross-connection.Maybe a place to start.
@ January 13, 2012 1:31 PM in maintaining temp vs cold start boilerAt this stage in the life of that boiler, I wouldn't start subjecting it to extremes like that. Just my thoughts.......
@ January 11, 2012 10:56 PM in Only one baseboard in zone workingHas any of the attempts at purging resulted in the baseboards working at all? If all the plumber could do, was identify the problem and not resolve it, it's time for a new plumber.
@ January 11, 2012 8:03 PM in mono flow bluesIf you are going to try using 2 monoflows, make sure the red stripes are facing each other.
@ January 9, 2012 10:28 PM in zone control valvesI don't know any details.It was something I came across, and figured I'd let you know about it. Good Luck
@ January 9, 2012 5:22 PM in It's cold. Poor Unico install. Want to re-use 3rd fl. radiatorsLet me guess...........he plumbed to the heat exchanger in the air handler with 1/2" pex?
@ January 9, 2012 1:36 PM in It's cold. Poor Unico install. Want to re-use 3rd fl. radiatorsI'd set it up temporarily to give priority to the first floor.A call for heat by the 1st floor stat opens a relay and shuts off the 2nd floor.This makes the full output available to either floor, just not at the same time. Sort it out in the spring.
