Homemade Hot Water Shower Might Shock You

DIY Hot Water Shower

[Stephen] doesn’t have the luxury of readily available hot water in his apartment, and since he’s just renting he didn’t want to buy one of those instant powered units, so he decided to go ahead and build his own!

He’s using a submersible 1000W immersion heater in a 2.5 gallon water container which has been mounted high up in his bathroom to let gravity do the work for actual shower. It’s not quite an instant shower unit as the water needs to heat up like a kettle before being used — this takes about 4 minutes to hit the optimum temperature.

The current shower head installed drains the tank in about 2.5 minutes, which might not seem like much time for a shower, but let’s be honest — we could all probably cut back our shower time and save some water for the environment! Something one of our Hack a Day Prize entries is hoping to solve through music!

DIY solar collector boost your hot water system

This home is heated by a wood stove in the winter, which also produces hot water. But the other three seasons it’s an electric water heater that does the work. This latest hack is a solar collector meant to take over the hot water production work for the house. it uses basic building materials and rudimentary construction skills, making it much more approachable than trying to make electricity from the sun.

It’s really just a wood box with a glass lid. The inside has been painted black, and the black tubing that snakes through it holds the water. A three-way valve lets the homeowner patch into the hot water reservoir. The collector is lower than the¬†reservoir, so the heated water makes its way back into the tank as cooler water takes its place. Not bad for an entirely passive system!
