If cracked, combustion vapors will get blown into home circulating air, like if a radiator has a leak the fluid will spray out slowly, right. 

The piping could be air locked (no hot water circulating).

You'll feel poor, unfortunately, because you'll start pulling a lot of cash flow out of circulation to set aside.

This inflation factor is already known even decades ago that home price would just go up following the circulation of money.Nonetheless, primary housing is much more important than oil, gold, and timber combined LOL.

Then there's your HVAC ductwork that's been contaminated, circulating that crap. 

So it depends on how many "tickets" are in circulation.

I also have it set up so that if the temp drops below 69 in cool mode, it sets the temp to 70 and then turns the fan to ON so that the air keeps circulating but it doesn't keep cooling.

Happy to discuss and share some of the opportunities currently being circulated. 

A vaccine was developed and but the strain is still circulating as a common flu strain. https://www.cdc.gov/h1n1flu/vaccination/public/vaccination_qa_pub.htmThe media is trying to compare coronavirus to ebola, which is insane based on risk and mortality rates.

Long story short, this woman (bad neighbor-happened to be an attorney) wrote a letter of complaint to the building and planning dept claiming my adorable tiny house was blocking a nonexistent view of the ocean (beach views are not possible due to flat neighborhood), "decreased the enjoyment" of her use of her property and (my favorite) was interfering with the air circulation in her home, etc, etc.
