Well there was often explosions on.MacGyver so I am sure it is not a good idea!

Another option would be a hydronic heater and they offer a heat loop for the hot water but they run on diesel. It is kind of pricey.
Either the company is unethical or ignorant ! ABYC do not "Approve" anything at all, they merely set a standard.

Causing a propane tank to explode is a tremendously difficult undertaking. You can drop them, hit them with a car, sometimes even shoot them and still an explosion won't happen. They're a safe energy source as long as you aren't placing the bottle directly inside the fire.

I don't believe anyone expressed concerns about the tanks.
Oxygen depletion, carbon monoxide poisoning and propane leaks should be the concerns

True, and you'll have to worry about ventilation with most hot water systems, including a propane system. They're mostly used outdoors anyway. Just take your shower in the summer with some jury rigged curtains and you'll be fine.

Re: Tankless Water Heater, CNG?

We have been using our vent-less Excel for 5 years without any problems. We have a dedicated LPG system for it along with a water solenoid that opens the supply to it when the LPG solenoid opens. This keeps the system from trying to ignite when the water is on, but the gas is not.
