So people would use a mercury seal to put pressure on the water, allowing the system to run hotter without boiling. I didn't quite follow this part. Where in the system does the mercury go, how does it add pressure, and does it have anything to do with Wikipedia's description of using mercury in glass-to-metal seals? https://en.wikipedia.org/wiki/Glass-to-metal_seal#Mercury_se...

Here's an EPA document which shows some pictures, look at page 2 for the unit the OP has.

It may have cost you $50,000 but you now have +50 karma on HN and rising. Some would say a bargain! ;-] In all seriousness, cool story, glad you're okay, and this makes me think "insurance" as a business needs to be re-thought entirely. How many times has it happened that insurance companies weasel out of paying? Objectively you might think THAT was their primary job.

I'll throw my hat in the ring. Recently had a car totaled when getting it shipped cross country. Apparently because it was an "Act of god" (a hailstorm, with what looks like fist-sized-rock-hail in that every piece of glass and most trim on the car had holes in it, although I'd argue the insurance was for the idiot driver who didn't pull over or cover his load.) the insurance company refused to do squat. The car was…

We went through a very similar experience when our car was being transported half way across the country. They driver somehow managed to roll his trailer on a freeway curve (his claim was high winds). His insurance company tried to claim act of god because "the wind did it".

I'm still trying to figure out how the wind pushes over an open trailer with 2 sports cars on it. At least mine was 4 or 5 years old at the time, the other car on there was brand new and had only been driven far enough to get it on and off the trailer.

> I didn't realize that mercury spills are such a huge issue until recently. As the post mentions, the world at large didn't realize that vapors from mercury spills are toxic until recently.

Um, someone (not saying I) may or may not have played with mercury from a broken thermometer as a child. Is that person (not necessarily I) a walking health hazard? How does this work?

It accumulates in the body (since it takes decades to go back out), so one-time small exposure is not so bad. Long-term exposure or a very high exposure (like drinking some) on the other hand...

Insurance companies cannot credibly cover acts of god, aka correlated risks, because they happen to too many people all at once. It's not a simple matter of "fixing" insurance for those matters. NPR's Planet Money had a good discussion: http://www.npr.org/sections/money/2014/10/03/353030214/bedbu...

We're talking about hail. Insurance companies cover hail damage all the time.

(Actually, hail claims have been going up: http://www.claimsjournal.com/news/national/2014/05/02/248354... )

It's a pressure valve. Here's the patent: https://heatinghelp.com/assets/documents/141.pdf I don't think I've a clear enough understanding of how it works to try to explain it.

It's essentially a pressure regulator I think.

Insurance is such a scam. A friend of mine made two claims within about five years: once for water damage and once for a burglary. The insurance company agreed that she was covered. So they paid her and then dropped her. No big deal, right? Wrong. Once you've made a claim or two against your insurance, it can be very hard to get any new insurance company to cover you. She finally did find a new insurer, but the price…

> She finally did find a new insurer, but the price has gone way up -- negating her original claims. This isn't a scam at all. That's exactly what you'd expect from insurance. Insurance isn't there to save you money. In fact, the expected value of an insurance plan is always going to be negative on an infinite time horizon[0]. The whole point of an insurance plan is to smooth risk : instead of the small possibility o…

So if they're adjusting premiums such that they're net positive on every single account, does that mean they'll refund your money if you end the contract without ever having made a claim?

"Because of this, I avoid making any claims unless absolutely required."

This is economically efficient behavior - and in fact you should set your deductible to the highest amount you can afford out-of-pocket, as insurance is really only efficient for amounts above that. You should be aiming towards insuring catastrophic loss - eg, a fire that burns your whole house down.

Insurance has got to be the best business to be in. In what other industry is the business model "take people's money and don't do shit"? Plus, in a lot of domains people are required, by law, to get insurance.

It's great.

Author here: happy to answer questions.

How long have you owned the house? Toxic waste like that are grounds to sue the previous owner if not disclosed during the purchase...at least in California.

This page describes that system, I think:
