:whistling2:I like gathering opinions. :whistling2:



I worked for a fellow today that was one of the big wheels for American Water Heater Mfg.


We started talking about those water heaters that whirlpool has so many problems with, and the conversation I had with him was very enlightening.

We got started on the FVIR technology and other aspects of safety.

Putting a water heater on a stand


Or leaving it on the ground.
Safer from WHAT?

Non FVIR needs to be on stand in garage to prevent big boom.

All INCLUDING FVIR , in garage, need to be on a stand if not otherwise protected from BUMP by auto.

Good strong earthquake straps...no reason NOT to be on a stand.

What is your point????

No link, but there is a video on a CD I'm trying to get from this guy.



The video proves that the application of the stand is far more disasterous.


Reason:


2 mock tests were done in a concrete vault. Simulated gas can being knocked over. Oil based paint is also a known flammable.


When the water heater at ground level ignited the flammable liquid, the intensity of the flames were minor in regards to the situation.


When the water heater at 18" on the stand?


Keep in mind that there was a buildup of fumes that had to crest to 18" to find that source of ignition. When the ignition took place, the intensity and explosion was far greater, and that vault was a massive fireball when it ignited. Basic thinking implies far more percentage of fumes before ignition point.

This fellow told me they that they was trying to lobby to get rid of those stands, given the testing that was done that proved the % of flammability was increased by raising the source of ignition, and the result was far greater damage/destruction.

Exactly....The room fills up 18" of fumes then it gets set off. I posted this same theory in thread couple months ago. More fuel=bigger explosion...simple.

What was the area of the concrete vault? How airtight was it?

Is it likely that flammables could build up to this source?


How many cases of raised water heaters causing explosions in real world situations?

I think it's kind of moot to change the law now.


Eventually some nut job will be on a crusade to eliminate gas water heaters and only allow electric.

Either that or make all gas water heaters FVIR, Direct vent built into their own sealed rooms with electronic whole house combustible gas detection sensors coupled with a wags valve and standby halon extinguishers.

Either that or install intrinsically safe sealed fans and vents into opening on the floor.

How about telling people to better secure their flammables? Naaah, that would be too easy. Stupid and lazy will find it's own folly.

I got no dog in this fight

This is the information they gave me and until I heard it, I always felt positive about the stand being a fool-proof idea.


But codes and regulations, laws were designed to protect the public. All codes don't always follow failsafe measure.
