From my experience, I can also spot the difference between a floatation device and a shark, and occasionally enjoy going shark fishing ... most newbies can't and believe in fairytails because they want to and there are plenty here that are happy to cater to that tenancy; I'm not one of them, so I guess that makes me a fear monger; some people have to learn the hard way.

If you have hydronic radiant heat (in-floor/wall/or ceiling), solar thermal is capable of heating the water sufficiently on its own (meaning you can have a smaller in-line boiler or hot water heater as an ancillary heat source for a string of overcast winter days when the array may not be able to sustain the temperature of the storage tank.

The problem with most water tanks is when they break, they leak.

So I am looking at this duplex and it has propane tanks for each unit.

If you buy a stock and the company tanks and the stock value goes to $0, it is just a loss of IRA capital with no tax implications. 

It's the quickest way to have an investment tanked, if your PM is horrible.

Plumber's are charging 135$/hour. 5 water heaters because each unit has its own natural gas 40 gal tank water heater, and 1 for the laundry room.

We are all very fortunate to live in this great countryHere is a nice quote:You have to love a nation that celebrates its independence every July 4, not with a parade of guns, tanks, and soldiers who file by the White House in a show of strength and muscle, but with family picnics where kids throw Frisbees, the potato salad gets iffy, and the flies die from happiness.

Seems something inside the tank broke and as a result it was running however, the water came from the toilet, not from the tank which doesn't make much sense unless it was clogged.

From time to time they offer rebates on things too, such as older boilers, water tanks, tankless, etc.
