Re: Low level Co exposure
Levels near properly adjusted gas stoves are often 5 to 15 ppm
So I guess you are all behind the electrification movement?
Re: Low level Co exposure
The medical community has, thus far, pretty much ignored CO. There is a dearth of information on it. Aside from a smattering of papers and studies, consider these points:
CO is a poison
It binds up hemoglobin so it cannot transport oxygen to every cell in the body. Therefore, you begin to get cellular suffocation.
COHb does not help remove the metabolic waste piling up at the curb so to speak. The lactic and pyruvic acid must be cleared by the other pathways resulting in metabolic acidosis.
Listed CO alarm alert algorithms are based off COHb for a smoker- 10%. UL and the great minds of the world are ok with you living day in and out at just under 10% COHb indefinitely.
God designed your cells for a specific oxygenation-At 760 mmHg or torr PO2 your PaO2 runs about 100mmHg O2 normally at rest. Venous CO2 runs btw 30-40mmHg. The resilience of the human body is limited. You can hold your breath for a few minutes. Your body suffers biological death of cells after about 4-6 minutes of cardiac standstill.
They're learning more as we go. The myoglobin in your blood and muscles store CO.
It has limited short term beneficial effects at times in the body, which is why we produce tiny amounts of endogenous CO (in the body) but exogenous CO is harmful. There is no good way to measure, either quantitatively or qualitatively the harm from CO but consider this: All poisoning is dose over time. The longer the body's cells are exposed, the more damage- period. That's all anybody needs to know to appreciate the hazard and the need to prevent, detect, and eliminate.
Re: Oil furnace explosion - audit, thoughts
I take it you did not have the home and outbuildings looked at by a housing inspection service???
You need to have your insurer send an arson investigator and draw sample of the fuel in the tank to have it sent out for analysis and go from there.
The problem for you starts when the insurers arson investigator walks on the property and asks where the lock for the fuel tank is? Then he or she walks in the garage and sees the furnace "IN THE GARAGE", Then it becomes "LUCY, YOU GOT SOME SPLAINING TO DO".
You have to decide if you want to deal with this as is and possibly have your insurance canceled or simply have the oil dealer remove everything and install a through the wall pro-pain forced air furnace.
my thoughts as a homeowner with a worthless insurer.

Re: new work truck
For what it's worth, at my company we've had all Chevy vans and one Transit and one Nissan. Everyone disliked the Nissan but it did make it to around 200K miles before the cost of repairs became high enough to take it off the road.
The Chevy vans have been tough and reliable. I've always felt like they were the best and most comfortable to drive, although I have never driven a Sprinter. Here in NY it seems like every Sprinter I see has a problem with rust.
And that brings me to the Transit at my company. I believe it's a 2019 or 2020 model and has less than 150K on it, but it just failed inspection due to a rusted out frame. The body has no rust on it at all.
Re: Help: What's an affordable way to get a smaller, one pipe steam radiator?
You do understand that a smaller radiator, less EDR (Equivalent Direct Radiation) will give you less heat when you need it the most ?

Re: Fujitsu hp expert/contractor rec for retro-commissioning
As soon as you said one head was meant to heat the whole floor, I know it is not designed properly. I'm sure its doing all it can, it will just never heat the space adequately.
Re: Delayed condensate returns
Everyone was telling me you don't need a feed tank you have a major leak. So far that is wrong.
If what you told us is correct, it's not wrong but things aren't very clear in this thread.
Don't forget, wet returns are full of water. The fresh condensate itself doesn't have to return, the condensate on far end falls and pushes water more or less instantly into the boiler. Boilers are made to hold enough water to supply the systems for which they are sized.
You really seem to be holding onto the idea that you could be using 2.5 gallons per cycle and yet not have any leaks. Either you aren't actually using 2.5 gallons per cycle, or you do have a leak. You can't be using that much water and not have it be leaking out of your system.

2022 Pro Ram high top $70 K out the door. Add another $10 K for Ranger shelving.

Re: new work truck
I've owned a fleet of different work trucks over the years and worked out of all of them; station wagon, utility truck, minivan, full size van, box truck, sprinters. The best to work out of, that covers all bases is the SPRINTERS.Mad Dog
