    DIY advice, and to what extent it can be given, is an issue that's being discussed continually around here. The concern of the owners of the site is the liability that arises when someone gets hurt...

    True -for the most part, but there are ways. If I went into detail, you would obviously know, but then I would be giving DIY to anyone who views this.

    I stated my reply in a very generalized manor...

    Apparently, you didn't notice the header at the top which forbids DIY in this forum.

    If you're a tech, apply for pro membership and post your question in one of the pro's forums.

    A wireless or communicating stat is what's needed if you only have two wires.

    You may be trying to correct the symptom and not the cause. Is your tubing O2 barrier?

    Making it better? Seriously?

    Leave it alone. You're not smarter than the engineers that designed it.

    You won't be making it better; you'll be making it deader - as in much sooner.

    Ask the other "dealer" to produce proof, not hearsay. That boiler's been in Europe for 20 years with a pretty good track record.
    It's it my favorite? No, but we all have differing opinions.

    A simple recommendation:
    Forget about a new duct system; you have no assurance that the problem won't continue. Add some baseboard electric heaters in strategic areas for some back up heat and keep...

    The input of the electric is 15btus. With the indirect, you will have the complete output of the boiler if pumped, piped and controlled correctly. In other words, about 3 to 4 times what the electric...

    The boiler should be sized to the heat loss of the structure, not the size of the indirect. The rating numbers seldom match up exactly - they're just guilde lines to help calculate what output can be...

    To answer one of your original questions: yes they still make 80% furnaces. But the same insulation, glues, etc are used in both efficiencies.

    I was simply trying to show the OP that there are specific scientific formulas that prove what everyone else had simply stated: namely, that a 14x8 duct was way too small. I was just presenting it...

    A dual fuel stat would cause the circ to turn on and off with the stat once it reached balance point, above that, it would stay off. In other words, the stat would control temp by cycling the pump...

    I don't understand either of your comments. What's DIY about using a recognized formula and method to calculate duct size?

    Second, what in the world does their location have to do with proper duct...
  16. What is the listed temp rise for the furnace?...

    What is the listed temp rise for the furnace? It's on the data plate. You must have enough cfm to keep it in that range. The higher the cfm, the lower the temp rise and the more efficiency.

    More info is needed such as a piping and control layout to determine exactly what your contractor is proposing in detail.

    The 2107 is NOT an on demand control. That means it does not fire the burner simply because a thermostat initiates a call for heat. Instead, it maintains boiler water temp based on its reset curve....

    No, the large pipes are actually an asset as they provide mass which acts as a buffer to prevent short cycling of the boiler. Mod/cons are low mass and short cycling is a common problem especially on...
