Water Heater Blast

[monkeyman1140]

Modern water heaters are designed to blow up rather than out, so it won't destroy your house but it will punch a huge hole in your roof.

[remnant1978]

great! my bed is right below our water heater!

[randallhilton]

@monkeyman1140

Not quite accurate. Electric water heaters will tend to "rocket" upwards due to the bottom blowing out. Gas fired water heaters will tend to split on their side because the burner area and flue reinforce the bottom, making the side the weakest point.

[douglas787]

That was great. Now let's have a demo of one in a typical stick frame house, not a new one of course but one scheduled for demolition. I'd love to see the damage that a forty gallon water heater could do under the same conditions.

[9foot6]

yea watched a really old school video for my apprenticeship, that was mean.

scary to see how comon this can happen, aparntly in nz like 3 went off last year

[diablo313]

When they say the water heater would explode, I'm thinking they would do more of a "traditional" explosion like a gernade. Never thought a water heater would explode like a rocket though.

Nice demonstration.

[W1LDWESLEY]

check hho projects on this sight and see how you can apply it to your demilitions and accidently turn it into your doomsday(if you dont research enouph).

i think mythbusters still have that beatin.

[IronHorsez88]

That was a tiny water heater, nothing like the ones in most homes that are 30-50 gallon - 3 times as big, and the blast might be 10 times as powerful.

[IronHorsez88]

You tell us to check the t&p valve, but how please tell us that.

[veryslyfox]

By burying the water heater in this video, they confined the blast pressure thereby increasing the force of the explosion.

[randallhilton]

Actually, it wouldn't increase the force. The reason for the hole was to make sure the tank went up, which was more predictable than if it had been allowed to fly horizontally. We didn't know if the side would split or if the bottom would blow out.

[veryslyfox]

Yes I know why it was buried, but it doesn't change the fact that burying it will direct all the pressure upward. The expanding gases have nowhere to go but up, thereby increasing the force of the launch

[9020powrmax]

You ought to try it with a Gas water heater (Tampered with of course) **BOOM** would probably be faster due to water getting heated quicker..........

[LukeL007]

For reference a pellet gun fires a projectile around 800-1000 fps, the same as this water heater.

[XHerbmanX]

for reference a pellet weighs a gram, a water heater weighs about 70 pounds. Luke is a fag. stupid.

[JustAHumbleMumble]

yeehaa i hope i never muck up any install i do, this is why if you have a problem with water you should call a experienced plumber cus theres alot of shit that hapens behind the scenes in plumbing that if you dont do plumbing you dont know how your actions are going to turn out , So go and lift the handle on your cylinder relief valves at least once every 6 months,expect some drips from the cold water expansion valve due to expansion but if hot warter dripping time to call a plumber before BOOM!

[garysvids]

Wow.

[xexyz]

awesome vid. I use to service them so its funny to see one go flying lol

[thegiant1]

Put checking the water heater on top of my list...

[Wehategod]

That was so kool Its scary but Man the launch was great

[theshipman]

What was the Myth Buster PSI durring an explosion? like 250?

[randallhilton]

Not sure but 250 seems a bit low. Of course, they're only rated to 150 so beyond that anything goes.

[theshipman]

Man, I godda get mine checked...

[LUNA71CHEVY]

in pheonix and that house where the heater exploded is going to be knocked down due to the damage the heater caused to the house

[joecrumb1]

An electric water heater exploded (Rocketed) out of a house in Phoenix(8/15/08). It destroyed most of the house,took out the windows of a house across the street and landed in a school yard about 100 feet away,

UNBELIVABLE!!.

[randallhilton]

I think that distance was more like 135 yards . . . 400 feet. Interestingly, that's about how far ours flew.

[Clevelandmarko]

CSI needs an eposode with a timed water heater explosion.

[mechanicwarrior20]

WOW

[AvatarBruno]

yes...that will blow up my house..

[REWYRED]

HOLY FUCK! I would have liked to have been around when that went off! LOL generator to power the tank? you could hear it "unload" after the tank went into orbit

[abclala1223]

I have a 60 gallon water heater in my basement. Now I'm scared to go down there near it :D

[grodenbarg]

ROTFLMAO! "extended warranties" are a rip-off anyway. Even Consumer reports says so. LOL

BTW that was cool.

[Creamlistner]

lol, just saw this on Mythbusters, tis awesome xD

[mpwelk]

Great video.

[imazappafan]

And that's just a 12 gallon tank!! Imagine a household heater.

[zincdustdust]

In the UK its illegal to fit un-vented cylinders without being registered to do so

[RedGreen7373]

Ya, I go to a Tech School and take plumbing for a shop class. We have been told by our teacher that an exploding water heater can be dangerous or fatal, but holy crap! I didn't know they could make that big of an explosion!

[RedGreen7373]

Ya, go to a Tech School and take plumbing, I heard an exploding water heater can be dangerous, but holy crap! I didnt know that they could make that big of an explosion! I have always wanted to see footage of it actually happening.

[blackphosphor]

hey i a saw a video where they were testing flammable liquids/vapors around the water heater. people should be aware of how dangerous that can be too.

[spencnaz]

LOL, I'm laughing like an idiot watching this.

[nushnik]

Why hasn't anyone ever built a steam powered cannon? :)

[Tangroo]

lol
