The Dude.
Erev Shabbat at the Muqata residence.
One by one, the kids shower, and get ready for Shabbat.
Plenty of time...always plenty of time. (Read the link if you haven't seen the story before)
[insert Jaws shark attack music here]
10 Minutes before Shabbat, I'm the last to take a shower. It's late, but I can make it....and then...there's no hot water left.
Not even lukewarm. Nothing.
The "Dude" was on for hours, but 7 kids will empty out your hot water supply quick enough.We tried the "Gush Katif Always Available" hot water system.
Alas, it caught fire.
I climbed into our attic to see why there was no water pressure and saw smoke coming out of the "new and improved always available water system" -- I spent the rest of the day on oxygen in the emergency room.
Needless to say, that was disconnected.
And maintenance is part and parcel of the dude. Following is my personal list of possible problems with your dude...
1. The most common of all is the "Guf Chimum" -- the heating element. Israel's water supply is based on "hard water" -- our water supply is rich in minerals, specifically calcium. The problem with calcium is that when heated, it bonds with metal, causing all sorts of problems. The electricity based heating element in the dude dies every 2-3 years and needs to be replaced.
Its programmed to die on Erev Shabbat, usually in the winter, and usually when you have lots of kids around -- the more kids who need showers, the more likely it is your dude's "goof chimum" will die when you need it most. To replace it, you need to remove the old one...which requires all the water in your dude to come splashing out. Of course, your dude is probably in the attic -- and my house doesn't have a concrete floor under the dude -- just rafters and plaster, so I need to be careful that the water doesn't damage the plaster (and cause the whole floor/ceiling to collapse).
While I personally don't recommend replacing a guf-chimum on your own, here's a short video for the very brave (or foolish). Keep in mind; replacing it may cause your dude to leak, and then you'll need to completely open it up again to fix the leak... While I consider myself rather handy, I try to avoid dealing with the dude.
2. The Thermostat. Mounted underneath the dude -- these have a life expectancy of 3-5 years and can cause 2 problems. It can die, and not allow your dude to heat any water. Or, it can die and allow the dude to heat itself up as hot as possible. Without a fail-safe pressure valve on your dude, it could explode (see #3)
3. The Dude Split. The life expectancy of a dude is 10-15 years. The seam of the dude may start to leak, giving you an early indication to quickly replace your dude. The longer you wait -- the more dangerous it gets. A neighbor of ours was lucky. He went into his attic to examine his dude, and a minute after leaving the attic he heard a massive explosion upstairs. Outside his house, neighbors thought a bomb went off -- also because of all the smoke coming out of the roof tiles -- but it was steam. The dude exploded due to a faulty thermostat and a small split in the dude seam (and a possible broken pressure valve). My neighbor benched gomel in shul, having narrowly avoided getting burned to death by the exploding dude.
4. The Leaker. The seals around the dude's feeder and exit pipes (cold water going in, hot water going on) erode over time and need to be replaced. Similar to replacing the guf chimum, this requires draining the entire dude.
5. The Deep Freeze. When cold winter nights hit Israel and its around 1-2 degrees Celcius (or 32-35 degrees Fahrenheit) outside, if you don't leave a small trickle of hot water running, your dude's solar heating "koltim" (outside panels) run the risk of freezing...and exploding.
So, while it sounds like a great idea, these hot water boilers are rather high maintenance....and extremely inconvenient when they break down on Erev Shabbat.
There are other solutions, like the "heat water as you go" gas system...and some claim to have miracle systems which keep calcium/lime from accumulating on the guf chimum.
I don't believe in miracles. Well, not if they have the word, "dude" in them.
