Homemade Water Distiller Built in Less Than an Hour

Here is a simple but efficient homemade water distiller that should be able to help us meet our daily water needs.

As one of the most important elements of life, water can cause serious inconveniences when missing. Speaking of potable water, you have to admit that the idea of drinking tap water has become, for many of us, the last alternative. So, instead of drinking tap water, we often buy it from the market. Now, we can’t rely  on this water either, because for all our daily needs it will involve lots of spent money.

So, one of the best ways left to provide clean water to our homes is to purify the tap water using water purifiers or distillers.

What you’ll need to build this homemade water distiller: a metal pot, stainless steel feed-through fitting, a plastic hose, glass jug, detergent, a stove and of course tap water (the entire assembling process should not take more than an hour). Before you start building the water distiller, make sure all of the components are clean. Use warm water and detergent to clean them well prior to assembling.

First, you need to drill a hole in the lid of the metal pot. Here you will insert a feed-through fitting. When the water in the metal pot will start to evaporate (boiling at 100 Celsius degrees) it will pass through the stainless steel feed-through fitting.

When the homemade water distiller begins to work, you have to let the steam escape for about 5 minutes from the feed-through fitting. After that attach a clean plastic hose to the feed-through fitting (high temperatures-proof) that will help you get rid of the remaining contaminants, if they still exist. Place the free end of that plastic hose in your glass jug and start collecting clean drinkable water. The water resulted after condensation will be pure. You can store it in plastic bottles.

This is all you need to know if you want to build such a simple homemade water distiller. Give this plan a try. Good luck!

    Bit scary in terms of energy and hence CO2 use.

    Water takes five times more energy to vaporise as it does to boil – we are talking large amounts of energy here especially in a homemade device like this with no insulation and very low thermal efficiency in terms of the energy of the flame actually heating the water rather than the suroundings.

    If people on this website really are GREEN then maybe they could first pay for a water test to make sure they really need distilled water, secondly they could shop around for a machine that does the job efficiently and thirdly they could look into the reported health risks of drinking only distilled water.

    Finally if you like in a relatively unpolluted area you could consider collecting and then filtering rain water and get that tested as well. Rain water is contiminated only by any airborne particles that it encounters during nucleation and the drop to the ground. If you filter rainwater then you are removing particulates – at least those that your filter will trap.

    Finally please do some research on the supposed health risks of drinking distilled water which appear no better substantiated or scientifically supported than the supposed benefits.

    Scary to see Green advocates being so casual about energy use – what is it to be Green, what is the balance between our hunger for energy and our stewardship of the planet. I only hope that this particularly UNGREEN health fashion does not spread far out of the US – do people just get bored if they are not burning carbon fuels?

    Btw, this is a great idea nonetheless, sorry if my opinion wasn’t inferred from my previous comment. I live in an area with lots of arsenic and heavy metals in my drinking water, so I will be employing this it a similar method to purify my water.

    It would be nice to see more pics, especially stages of the build. Also recommendations where to get high temp-proof plastic tubing as well as links to the correct feed through fitting design, since there are so many different types out there (some of which are absurdly expensive).
    Thank you.
