Hot Water Without Electricity

Here’s a great video from engineer775 of showing how he constructed a water heater out of used materials and wood. Knowing how to heat water without electricity is practical because it ensures that even when the grid goes down, you’ll still have a means to get hot water.

Great idea isn’t it?

If you want to know how he coiled copper tubing with ice, watch the video below.
