@ March 6, 2014 3:01 PM in TT PE110 longer run timesof the supply at any point, you risk having a system that never catches up, thus always running, right? Therefore, every system has to be run on supply water that is at least a little hotter than actual BTU demand to prevent this. It just seems unpractical to try and hit the 101% mark, at all heating points thru out the course of any given heating day, if not impossible. I think for most of us, reasonable run times of 1/2 an hour or so, are much more realistic.
@ March 6, 2014 1:03 PM in TT PE110 longer run timesthat having your system always running is the most efficient way to heat a space? A lot of people seem hung up on trying to reach this goal, but is it the way for every modcon install to work for long, or short term dollar savings?
@ March 5, 2014 3:19 PM in Fuel use question?of homes are more efficient than yours-but you are better than 9.8%-so you are in the bottom 24.5%-
@ March 5, 2014 2:49 PM in Fuel use question?If I remember right, this puts you in the 88% group-only 12% of homes have a better efficiency than you-

@ February 19, 2014 10:47 AM in How Much Vibration In a -fixed the problem-fan must have been made out balance-nice and quiet, vibration is just about gone-Lochinvar was very good about resolving this issue, many thanks to them-
@ February 17, 2014 11:34 AM in is it worth converting from oil to propane ?can go with a modcon, you have enough baseboard, and your boiler needs replacing anyways. I did this and am using fewer gallons of propane than I was with oil, and I am paying a dollar less per gallon for the propane.
@ February 14, 2014 10:34 AM in DHW Indirect Air EliminationAfter reading icesailor's and hot rod's suggestions, it became obvious that I had screwed something up. Thinking about the fact that the condition got worse after higher operating temperatures, I keyed in on the expansion tank. It was brand new, and large enough, but what about it' s charge, had I checked it? NOT-Added about 12 pounds of air, and presto, all air noise was gone-I guess I assumed it had 12 pounds of air, it only had a couple of pounds, dumb, amateur, mistake. System pressure is now at around 16 pounds, tank has about the same charge, and all is quiet as a mouse. Again, thanks to icesaiior and hot rod for all your help.
@ February 12, 2014 3:24 PM in DHW Indirect Air Eliminationon the sytsem-heating loop has no problems with air, quiet. I have had a rattle in the DHW circulator. I was able to get rid of it this morning by closing the isolation valve down enough to cause some disturbance, which shook whatever loose, I assume from the internal check valve. Rattle is gone, maybe it was causing some cavitation,we will see-
@ February 12, 2014 1:15 PM in DHW Indirect Air Eliminationthe system pressure was on the low side this morning, 12 pounds or so- I'll boost it up to 16, and check the tanks pressure-Thank you for your help
@ February 12, 2014 10:34 AM in DHW Indirect Air Eliminationloop doesn't seem to be an issue very often, so no one adds any air elimination devices?
My system seems to get air into the DHW loop when the heating loop works hard at higher temps, like last night's 5 degrees. The air seems get into the DHW loop and than takes days to work it's way out. I think maybe I need to add a scoop to the loop to take care of the air more efficiently. Any reason not to do this, or am I treating the symptoms, not the real problem?
@ February 10, 2014 12:24 PM in DHW Indirect Air EliminationI added a vent in a cross at the top for pressure release and LWCO-
@ February 10, 2014 12:05 PM in DHW Indirect Air EliminationAll of the piping diagrams I have seen provide no air elimination provisions in their setups. Is this standard? I am having trouble with air in my DHW loop, should I install something, if so, where, and what?
@ January 26, 2014 9:45 AM in Lochinvar Tech-Rhode islandNot so easy to find someone in my area with the interest or knowledge-
@ January 25, 2014 10:22 AM in Lochinvar Tech-Rhode islandI sent an email to him-hope he is interested-
@ January 24, 2014 12:20 PM in Lochinvar Tech-Rhode islandI am looking for someone who has Modcon experience to work with the people at Lockinvar to try and resolve an issue we have with a WH 55-You don't need to be Loch certified, but that would be best.. Pleae let me know if you are interested, or know of who I should be contacting in the southern RI area. I think this could be an interesting project for someone who wants to learn more about how these little boilers work-
@ January 16, 2014 5:33 PM in Separation of Air and Exhaust-or soffit, not from them-
@ January 16, 2014 5:31 PM in Separation of Air and Exhaust-So, it looks like I shouldn't separate the air intake and my exhaust vent more than 15" because of "pressure zones" issues. I wanted to dump the concentric and pick up my air from around the corner, maybe 12 feet away, 4 feet lower, in the eaves. Lochinvar says I could do this if I exhaust thru the roof, but not the sidewall. Doesn't make any sense to me, can anyone explain?
@ January 16, 2014 12:54 PM in Lochinvar WHN Noisepropane, whines at some firing levels as it modulates down. Guess I should be trying to get rid of the whine-Maybe I'll try running a little richer- Carbon Dioxide is at 10.5 now-
