Re: Installing new bathroom zone on a pretty screwed up system
I think Viessmann states boiler must not be connected to non barrier tube in their installation manual. Hopefully it is barrier tube. Although there could be O2 ingress at those fittings.
For under 160 sq ft, you might consider electric mat in the bath?

Re: Snow Melt Mavens, I need your advice
This was something that came up when the Dead Men began converting gravity systems to pumped systems. By bypassing most of the cool water returning from the system the boiler was able to come up to high temperature (and not condense), and that speeded up the heating out there in the system.
Re: Boiler Heats House and Pool
There are about a dozen of my customers that still have this brand of boiler working for them. Charlie Pistante - long gone now - was the guy that installed it. His sticker is on the cover plate of one of the junction boxes. He continued working well into his 80's because he needed the money to pay his wife's medical bills.
Such a simple system, no? Flue gas condensation? Probably, considering the pile of combustion debris below the burner. Maybe it's was self-cleaning.

If somebody decides to install an air to water unit in the future, they will thank you!

Re: heating oil tank manufacturer's warranty voided by transfer of oil from the old tank?
" Tank location should be chosen in accordance with the following requirements: ▪ The tank should be placed in an area where it is unlikely to be adversely affected by normal household activities; ▪ The tank should be placed in an area where it can be visually inspected from all sides; ▪ Under new NFPA guidelines, any outdoor steel tank fitted with a side outlet or installed in a top-draw configuration must be a double-bottom or a double wall tank. ▪ The tank label must be visible; ▪ If possible, tanks should not be located directly under house eaves where they may be subject to falling snow and ice or dripping water. Protection should be provided if there are no other placement alternatives; ▪ Tanks should not be placed in intimate contact with walls or structures since leaves and other organic matter can accumulate and cause external corrosion of the tank; and ▪ Tank location shall respect the local code for distance to property lines, to other energy sources or to other storage systems."
Re: repairing a neglected chimney, flue, thimble, liner, and leaks
Ed. I have considered that option too, a new stack. I even looked into a faux chimney facade to maintain the traditional look. many advantages to new stack, especially considering the condition this is in, and just like everything in this house has been neglected by previous owners. Agreed, do it right or don't do it at all.

Remodeled House. Now Radiators Are Way Too Large
We installed this boiler and radiator system in 2017 when the owners purchased this house. Nothing had been done to the building since it was built; single glazed windows, no insulation.
I sized the radiators for 130F water temperature as I wanted the boiler to condense and they turned out very large. My supplier says I order larger radiators than anyone else. I suppose that’s a compliment.
Recently remodeled, the radiators are now way oversized and I can drop the heating curve even lower. It’s now set to 1.1 with zero offset and the radiators will only get warm, not hot. Safe for their new children and more savings on their utility bills.
