Re: Savings ???? Repipe
It seems everybody wants there chimney gone but nobody has the bucks to to do a complete upgrade to hot water nor do they want to add a power venter to a atmospheric boiler cause it s to expensive and they want to save room . When i'm faced w that type of non mechanical nonsenses from home owners way before i start wasting time i give them a ball park idea of cost and that some parts of it will require other contractors and that i do not remove chimneys that's some body else's job which also is not for free . Usually that ball park is enough for them to keep the chimney and get it properly lined , I always think your removing your chimney for room ok ya just better moving lol .A few real turn offs for me as a sign thats it time to leave and i m wasting my time is we will be moving soon ,we would like to gain more space and we would like to reduce your fuel usage . I feel that if they have not done any building envelope upgrades in the years they have lived there then how you saving money w the latest and greatest when zero building upgrades have never been performed . pseudo science does not work and speculating is not a science when it comes to money maybe stocks but not mechanically its usually cruel stuff babe
With a steam boiler when sized ,piped and insulated properly w new main and radiator vents theres nothing that can throw as much heat as quietly as a properly installed steam boiler especially for old homes . Now weather there saving going w a new hot water boiler is a slippery slope especially when zero building upgrades have not been done with out which ya gonna need alot of panel rads or baseboard to meet that heat loose . Tough issues for sure .I never guarantee fuel savings w conversions what i offer is comfort .I think thats what we do correct or are suppose to be selling ?
Usually complete repiping and upgrading of a steam boiler will yield the best results in homes which have never had any sort of building upgrades .Properly done nothing in my eye heats high lose spaces as steam does w cost eff , Try that w hot air ,losing space and higher transportations cost for dist. Hot water excellent if using a cast iron using a mod con at high temp forget about it waste and will save only a small amount and yeah ok zero out short cycling and modulation but if ya replacing every 10 to 15 years there is zero saving when it goes to the dump . And i believe that most new hot air furnaces are pretty much pos garbage to boot being just about every contractor says there done at 11 to 15 years being there techs suck at service and seem to offer replacement over proper repair and service , as for mod cons any fuel saving will surely be lost on proper maintenance and service as i have seen from my experience .
The future will be becoming more and more interesting and funny also being the extent some will go ,i love a comedy so i always watch w a smiling face .
peace and good luck clammy

Re: Zone Valves BANG on opening only
The bang is usually from stopping a fast moving flow. Do you need the pump at that speed setting, 13 gpm? How many gpm do you actually need. Slow down the circ see what happens.
It would be nice to know which change actually cures this.
If you make multiple changes at once, we may never know?

Re: Taco 007 Circulator Replacement Sizing? Undersized even though working ok?
when you see a wall covered with zone pumps, pretty good chance none are running at the bep.
Ideally you run mid curve, doesn’t mean that you are:)
Run the lowest flow rate that will get the job done. Long 1/2” runs will be the gpm limitation

Re: Savings ???? Repipe
If money is no issue for her, sure go mod-con. But the cost of a chimney removal, interior updates, removing the entire steam system and installing a hot-water system is going to be some big $$$$$. Sure she will save maybe 30% per month…but it will take longer than the mod-con will last to recoup the savings.
If the boiler is getting older and is oversized a correctly sized replacement and repipe is probably save some money each month.
If the existing boiler isn't grossly oversized and is functioning properly, by fixing the near boiler piping she probably won't save much at all. She will probably just be more comfortable as the system will probably heat up quicker and more evenly.
Re: Maid-O-Mist Failure Rate ?
I don't think we have any evidence of the quality of any vent, neither in the past, nor currently, to be able to make any claims about that.
We have very minimal anecdotal evidence on a forum where people come explicitly because they are having some kind of problem.
Re: Taco 007 Circulator Replacement Sizing? Undersized even though working ok?
True. The cost for the material is around the same. But the headache, the labor involved is much less when using a cartridge. Unless of Course you can isolate the circulator with valves, then replacing the entire circulator is fine.
And as for convincing. Im sure you are weighing your numbers accordingly with the fact that it has been running well for some 16 years. If it aint broke don't fix it may sound silly, but may apply here.

Re: Taco 007 Circulator Replacement Sizing? Undersized even though working ok?
I get a considerably higher number: about 34 feet for 3 gpm in half inch copper 130 feet long. I get a flow for the 007 series around 1.5 gpm in that setting.
For the two loops in parallel, to have 3 gpm in each, you want something which will produce around 34 feet of head at 6 gpm.
Now I have to ask… are you sure about the half inch copper? Because if it's 3/4 inch the head loss at 3 gpm is only about 5 feet… which is easily within the range of the 007.
Re: Wifi replacement for aube telephone controller ct240
The relay has to be rated for the load that it will be expected to switch. For instance, the contacts in a normal thermostat are rated to switch ≈30 AC volts at some fraction of an amp; it'll switch the furnace on and off fine but fill fail (catastrophically!) if it tries to switch electric baseboard heaters. It's fairly likely that the Aube was switching low voltage, and that Shelly web relay seems to be rated for line voltage, but I can't be sure so I'm trying to cover the bases.
If the web relay uses an SSR of some kind instead of an actual relay for it's switching, there's a chance that it won't like the load that the Aube was switching. Another edge case that offers a small but distinct possibility.

Re: Interrupted vs intermittent Primary control
So there are some of the smaller gas power burners like a PowerFlame where they light the pilot with a spark, prove the pilot and then light the main flame then shut off the spark and keep the pilot solenoid open along with the main burner.
Wonder what to call that? The terminology make no sense.
Re: Interrupted vs intermittent Primary control
It doesn't power the transformer while the burner is idle, so it's intermittent. I agree it's stupid. The motor is also intermittent. I'm intermittent.
I remember some customers complaining about TV reception after converting from a stack relay to cad cell primary with intermittent ignition. As mentioned, the stack primary had interrupted ignition. I can't remember if it was VHF or early cable, but they weren't happy.
