Most Tico homes don’t have the necessary wiring or amperage to support water heater tanks (not to mention the fact that heating water requires a lot of electricity, which can be expensive). Those logistics coupled with the fact that hot water isn’t often necessary in this warm climate means that a simple, cheap option is often installed (note that I didn’t say that it was safe or even effective).
Enter the suicide shower, an in-line, electric, showerhead water heater. My first night using one was truly a shocking experience. There weren’t any instructions and since the water wasn’t warm, I reached up to adjust the knob. The little zing I received for my efforts immediately encouraged me to give up on that idea. I finished my cold shower in a hurry.
I have since learned that these devices seldom work, no matter what the setting. Now, I just try not to worry about it and hope for the best. Which is actually a pretty good way to deal with life in general, don’tcha think?
