Yes, that's a scary article but keep in mind that both safety devices have to fail to have the tank explode. The pressure release valve and the high limit on the thermostat both have to malfunction. Both of them to my knowledge operate at around 200 degrees F. The maximum you can set most water heaters is 150 degrees F but most recommendations are to set ...
Consider the sources; it is plumbers giving you a scare story to get you to hire them. See also "aluminum wiring".
It will take a chain of 3 events at once:
failure of the thermostat, causing the heater to overheat the water, boiling it.
the pressure relief valve fails to operate, preventing the pressure from simply blowing out the relief valve; that'...
An electric water heater explodes when the water in it starts boiling, producing pressurized steam that causes the heater to rupture. In order for this to happen, three things all need to fail; if any one of them works properly, no explosion will happen.
First, the thermostat needs to get stuck in the "on" position. If it's working normally, or if it ...
Water heaters have pans. You place the pan under the water heater, then attach a hose to send the water someplace less damaging.
You can also get water sensors, which rest on the floor and sound an alarm if water is detected.
There's less stuff for dishwashers and washing machines, as they only contain water when in use, and there should be someone nearby ...
Well, the answer is right there in the article you linked:
Always check your hot water heater’s pressure relief valve to ensure
it is in good working condition. If you have any concerns that your
water heater is not functioning accurately, have an inspector come
take a look at it.
The best precaution you can take to avoid having this happen to ...
Paint the Square D breaker or a Challenger breaker red and put it on top of the burned up bus stab. Don't use it.
Replace all black Challenger breakers with Eaton BR/C
Check technicolor BRyant breakers and make sure they are cross-listed Type C; if not replace with BR/C
Make sure water heater wire is 10 AWG
Replace water heater breaker with 25A ...
Some of these are supplied with “stop leak” hoses on their incoming supply pipe.
Also some washing machines have the base designed with a “dip” with a sensor to turn off the internal valve if it senses water - caught my ex-wife out for a week until number one son looked at it :) ...
I've fulfilled customer requests for overflow trays in cases of integrated laundry equipment, for example. You'd essentially install or build a shower pan (with all the same drain plumbing). What type and profile is appropriate depends on the situation. I wish my dishwasher had one as a one-time overflow recently did significant damage to my kitchen floor.
The Square D breaker you have in there now and the burnt breaker (Challenger A240 ?) are not functionally the same, the burnt breaker is a two-pole 240v breaker.
Would need a "before" picture too, but the breaker you removed would need to be spaced one half space lower than the Square D you have in there now. It would give 240v when properly installed.
Water heaters have replaceable parts in them:
The anti-corrosion anode rods (what a boater calls a "zinc")
The heating elements proper
The dip tube which is an internal baffle which brings the cold water down to the bottom of the tank
The dip tube needs further explaining. In stagnant water, hot water will rise to the top. However if it were actively ...
That appears to be a gate valve. There is a threaded portion inside the valve that goes inside of a block of metal that moves up and down when you turn the handle. Since you can turn the handle, but the flow of water doesn't seem to increase, the gate has somehow become detached from the screw. Maybe the threads have stripped out, or maybe the screw shaft ...
You have some...clean-up work to do here
What your installer did was a parts-off-the-truck hack job to get 240V out to your tank. However, it certainly isn't a proper job, given that they put an alien breaker in your panel!
Given the current state of the panel, what I would do for now is:
Remove the BD2020 and the C115 breakers in the top right and ...
Electric water heaters are easily repairable if you can get the old heating elements out of the tank. If they get too corroded, you may not be able to remove them without damaging the tank.
But, that is a bit premature. You need to test the resistance of the heating elements to determine if they are good. You can also check that the thermostats are ...
I'm surprised no one makes a water source heat pump water heater.
While the name sounds like a paradox, the science is sound. – David
They do, that's what geothermal is(excluding direct exchange
The problem with a water sourced heat pump for DHW is what do you do with the water? How do you heat it back up? Your gonna spend ...
