Re: Hydronic piping
how many fin tubes are you considering?
1/2” pex with a manifold system is an easy retrofit and gives you unlimited zoning potential. In some cases 3/8 tube is adequate

Re: 2 stage vs 1 stage furnace
"…How long do you think your car starter would last if you shut the car off at every red light, and then start it up again…"
In the last two years, between 65% and 72% of new cars sold in the U.S. have been equipped with start-stop systems that do exactly that. 😊
OK, back to heating. 😀
Re: Commercial Boiler replacement
I was told ions ago all equipment and materials x 3 and you will be able to do the job properly and possibly pay yourself a little . On a side note being a low baller will help no one when you did not make any money you usually do not return being you have a bitter taste like working for nothing . Which none of us like to do . As of lately that x 3 rules means nothing being the public utilities are charging way more but got to remember zero financing which leaves little guy like me outta the picture .
In these times x3 really isn't being greedy if your doing everything on the up an up unless ya skip a couple of steps you should be able to eat and lets not forget your business expenses and all the cost that your customers pay ya just ta get ya there . All that being said maybe ya like to make no money and work for free it certainly ain t me thats for sure .

Re: Commercial Boiler replacement
Tony Kiter (RIP), an Old Timer from Mineola and Licensed Master Plumber gave me a very simple Rule of Thumb when I was putting out my Shingle that I have found rings true in 2026:
"If you want every job, Double the cost of materials (1/1 ratio)."
If you wanna be "competitive," go two times the material cost (2/1 ratio)."
If you wanna make $$$, go three times the materials cost (3/1 ratio)."
You'll find YOUR breakeven and profit margin somewhere in there. Mad Dog
Re: New Yorker Boiler Coexisting with Hot Water Heater
i wonder if the electric tank is just used to keep the water heated by the boiler hot if it is traveling a significant distance to get to the fixtures.

Re: BAXI DuoTec 40 GA
hold on you said you have an airtrol fitting? can you take pics of the install? airtrol is a specific thing that involves a compression style tank, so if you have an airtrol that would tend to mean you have no air vents, which works well for a cast iron system but not when the air gets trapped in the boiler heat exchanger. need pics

Re: Seeking advice, new to boilers, boiler broke over winter
"Dual" in this case means there are two points of closure between the gas supply and the burners. It is required by Code for safety reasons and has been for at least a couple decades. But there is only one pilot on this valve.
Re: TigerLoop instalation for Bio Fuel 100 rating
Pipe them in copper. Tiger loop instructions call for replacing the Tiger loop after 10 years. I don’t recall seeing an expiration date on the standard flexible supply house hoses.
But I stopped using them as they would crack at the connection when flexing them while servicing the pump strainer.
I either use Ruby Reds (7 year recommended replacement) or run them in copper, leave them connected and unbolt the pump when I need to swing open a boiler door.
Re: Fire in roof unit of Historic Detroit Skyscraper
probably a motor burning up. if it is a cooling tower some use wood slats although most use some sort of composite or metal or older ones used asbestos cement. could be refrigeration oil or just decades of accumulated grease and oil too.
glycol solutions are also flammable in higher concentrations, i believe that was one of the ways that fieros caught fire.
