@ July 10, 2014 12:14 PM in Looking to make condensate neutralizerSorry for sideways picture-
@ July 10, 2014 12:05 PM in Looking to make condensate neutralizerI made one using a 1 !/2" drum trap filled with marble chips. Looks and works great-
@ July 4, 2014 10:48 AM in Pump Exercisepumps, the pump in question gets no use off season.
@ July 3, 2014 1:19 PM in Pump Exercisemaybe not? I ask because I have a Loch 55 piped direct, not prim/sec. I also have an indirect water heater. If I use the exercise program, the system will run the boiler/heating loop pump once a day, moving the residual hot water in the heat exchanger out into the heating loop. Seems like a little waste of energy to me, but if I risk having a pump freeze in the fall, maybe the cost of energy is worth it?
@ June 27, 2014 11:21 AM in Pump ExerciseIs exercising a Grundfos 15-58FC once a day in the off season a good thing to do, or a waste of start/stop cycles on the pump's lifespan?
@ May 5, 2014 8:38 AM in List of small mod/consJust to give you an idea of how much a modcon install will run, I spent $7,000+ on materials, including a 20 gallon Superstor, for near boiler work. The Lochinvar was maybe a third of those cost. However, I am saving at least 40 percent on fuel, going from an old, oversized, steel, oil fired boiler, to a propane fired modcon.
@ May 2, 2014 1:33 PM in List of small mod/consI just went thru my first winter with a Loch WH55 installed in a home with a heat loss of around 25,000-Being oversized by double, I can say there were no problems, no short cycling-Actualy, being oversized allowed the boiler to operate at only 30 to 50 percent, never any more, never maxing down to 20 percent for more than a couple of minutes in warmer weather, but climbing right back up to 30 percent for most of the cycle. For me, this is great, as the boiler is much quieter operating in these lower ranges. For anyone installing one of these in there living space, this is important, as they are not always whisper quiet, especially on start up, and shut down-
@ April 3, 2014 10:09 AM in Value of converting oil/steam to modcon gas?running at 85% on the old boiler, closer to 80-Boiler was 85,000 BTUs net, I only need 28,000-My case is fairly typical, most in place boilers are way oversized. My savings are real, and maybe understated-Also, I'm saving huge amounts on DHW, switched to a 20 gallon tank, plenty of water, recovers 10 degrees in about 8 minutes-
@ April 2, 2014 1:39 PM in Value of converting oil/steam to modcon gas?I just converted a small house from oil to a propane fired modcon. I am using less propane than I was oil, and thats after this colder than normal winter. So if you factor in the price of propane, $2.75 vs oil, $4-, my savings are fantastic, somewhere around 40%-I was hoping to break even, and be happy with the boiler moved out of a basement which super storm "Sandy" filed with four feet of water. Pleasant surprise-
@ March 31, 2014 1:42 PM in Modcons in Closets-reason for the ventilation might be the temperature of the closet. Triangle Tube asks that the ambient temperature not become to high. What would a reasonable maximum temperature be? If the closet stays at 85 degrees or so, is this reasonable? The temperature inside the boiler cabinet is certainly higher than this ? Never could it become high enough to melt the poly exhaust pipe.
I just would like to be able to leave the door shut at times to quiet the thing down when it does it's pre and post purges. Boiler is in a den, not a bedroom, and operates at a max of 60% by my choice, not some problem.
@ March 31, 2014 12:30 PM in Modcons in Closets-Units like these installed in bedrooms had to be in closets with sealed, solid , air tight, self closing doors at one point. Now, the lochinvar manual is calling for requirements that fit units that draw their combustion air from the interior space.
I'm not an idiot, this is confusing- The TT manual has no such ventilation requirements for closet installed units, as far as I can see- So-
@ March 29, 2014 12:11 PM in Modcons in Closets-and it looks like codes may require just the opposite for bedroom and bath locations, no ventilation, and sealing of the door. Well, now I'm really getting confused. All air for combustion is from the exterior, why would Lochinvar be requiring room air to be to be added to the closet? Maybe heat buildup?
@ March 28, 2014 12:22 PM in Modcons in Closets-from the code that covers appliances that take their combustion air from the interior, so I question the requirements-Local's are going to tell me to go by national code, which I am having trouble finding reference to sealed combustion units.
@ March 28, 2014 11:51 AM in Modcons in Closets-Are the ventilation requirements different than those for non direct vent units?
@ March 21, 2014 10:26 AM in Please critique this designbelow 120 degrees in slantfin, just don't seem to heat that well. I have been running nothing lower than 120, or higher than 140, seems to work well for me. I get run times of 1/2 an hour, or so, off maybe 40, 45 minutes. I know this isn't what the guys who want there modcons to always run like, but it works for me.
I also think if you go with the TT 60, not the Loch 55, yo will have problems with the TT not modulating down enough-
@ 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.
