Warm water is needed in everyone's life. It is used to take a bathe, to wash clothes, dishes, floors, etc., but one-seventh of the people in the world do not have access to warm water. It is necessity, especially in cold climates. Warm water is also used to remove oils, germs on the skin and bacteria that could cause illnesses. If you live somewhere that hot water is no accessible, or perhaps you're camping or roughing it at a cottage, you can build your own portable and affordable water heater. Portable water heaters have been made using simple materials like the following:

    Auto inner tube
    Was this step helpful? Yes | No | I need help

  3. 3
    Small clamp
    Was this step helpful? Yes | No | I need help

  4. 4
    ½-inch plastic pipe coupler
    Was this step helpful? Yes | No | I need help

  5. 5
    Good-quality rubber-sealing compound
    Was this step helpful? Yes | No | I need help

  6. 6
    Nozzle or hose valve
    Was this step helpful? Yes | No | I need help

Steps

  1. 1
    A secondhand inner tube shouldn't cost more than $1.50 from a tire store.
    A 14-inch tube can hold around 19 quarts of water. But if you would like a smaller or greater capacity, use a 13-inch compact car size or 15-inch truck tube.

  2. 2
    Make sure the tube is functioning well, and that it does not have holes water could leak from.
    You can test it by inflating the tube and listening for the sound of air escaping.
    Was this step helpful? Yes | No | I need help

  3. 3
    If the tube has no holes, now, using a pair of scissors, cut a ¼-inch hole about two inches from the outside edge.
    Was this step helpful? Yes | No | I need help

  4. 4
    Wet your fingers using water, and put them inside the hole to clean it.
    Was this step helpful? Yes | No | I need help

  5. 5
    Get a ½-inch pipe coupler and cut off the lower half.
    Was this step helpful? Yes | No | I need help

  6. 6
    Pour a generous amount of rubber-sealing compound on the ridge of the coupler, and push it into the ¼ inch hole.
    You may leave the tube under the sun for a short while for it to soften the rubber.
    Was this step helpful? Yes | No | I need help

  7. 7
    At the lower part of the coupler inside the hole, pull the ridge snug against the inside part of the tube.
    Let it dry for the recommended time. If it doesn't dry completely, the seal becomes worthless.
    Was this step helpful? Yes | No | I need help

  8. 8
    Clean the new stem, then roughen the spot just like the space around the hole in the inner tube that needs to be patched.
    Apply rubber-sealer to coat the outside of the tube. The cement becomes stronger and dries faster if applied with three thin coats rather than one huge glob.
    Was this step helpful? Yes | No | I need help

  9. 9
    Take two feet of old garden hose, and connect it to the new stem.
    Then let it stay under the sun too, for it to soften. Place the clamp around the stem and hose to connect them.
    Was this step helpful? Yes | No | I need help

  10. 10
    You will need a standard nozzle at the end of the hose.
    This is where you will connect the water control valve. If there isn't one available, you can buy a garden hose repair tool. This will cost less than $1 at most hardware shops.
    Was this step helpful? Yes | No | I need help

  11. 11
    For better use, you may use a funnel to pour water into the hose.
    Was this step helpful? Yes | No | I need help

  12. 12
    If you are getting your water from a stream or lake, you can fill up the tube with air first, then dunk the entire device into the water, and open the new valve.
    The water will enter, forcing the air out.
    Was this step helpful? Yes | No | I need help

  13. 13
    After that, put the device in the sunshine.
    When left directly in the sun, the temperature of the water inside the water heater will increase an average of 10 degrees an hour, leveling off at about 115 degrees Fahrenheit. For quicker heat gain, put the tube on the warm roof of a truck or car that is parked under the sun. You may extract water from this position as well.
    Was this step helpful? Yes | No | I need help

  14. 14
    To experience the function of the shower, you have to place the filled tube over your head.
    You are able to do this if you hang the tube from a branch or pole or put it on the roof of your camper. Just be cautious of the sharp edges that may result in a puncture. For a really good shower, you may buy a plastic sprinkler at less than $1 and connect it to the end of the hose segment.
    Was this step helpful? Yes | No | I need help

  15. 15
    For traveling and camping purposes, you may place the rubber doughnut on the roof of a shed or outhouse as a convenient and good source of warm water.
    Was this step helpful? Yes | No | I need help

Refill when necessary.

  1. 1
    When you're done with it, empty the tube then roll it up.

Other Ways to Build Portable Water Heater

Use a 20-pound barbecue tank. This can be carried on camping trips. Build a shed with sides, put on a Shur-Flo 12v pump with battery. This can be bought at about $125-250, depending on the model. This is wonderful to have in case of emergencies such as blackouts.

How to Make a Solar Hot Water Heater

  1. 1
    Paint it Black.
    Get a container and paint it black to absorb the sun more efficiently. Place it in the sun. The amount of heat it will absorb depends on the time of year, location, and how cloudy it is that day. Regardless, it is a great investment in order to have a hot shower in a place you otherwise couldn't.

  2. 2
    At the Plumbing Supply Store.
    Buy a 100-foot coil of ¾-inch black poly tubing that will cost about $20. To increase the volume of the water, you can buy 1-inch tubing instead. If you want cheaper tubing, then search for some on Craigslist.
    Was this step helpful? Yes | No | I need help

  3. 3
    Coil.
    Form the tubing into flat coil, and secure it with wire ties and a length of PVC pipe to keep it shape.
    Was this step helpful? Yes | No | I need help

  4. 4
    Insert the ¾ NPT threads onto each end of the plastic hose barb.
    Typically you can tighten a garden hose into ¾ threads. You can buy garden hose fittings. You can use a pair of pliers to snug the hose into the NPT threads.
    Was this step helpful? Yes | No | I need help

  5. 5
    Fill and Heat.
    Lace the coils and leave them under the sun and fill with cold ground water.
    Was this step helpful? Yes | No | I need help

  6. 6
    If the temperature is 75-80 degrees, after four hours, the water might become too hot for you to touch.
    To temper the water, you need a mixing valve. You can use a hose cocks to screw onto the garden hose.
    Was this step helpful? Yes | No | I need help

  7. 7
    Connect a hose cock on a tee and put a ball valve at the end of the tee.
    Take a shower head and remove the low flow restrictor. Connect the shower head into the ball so you can have a "navy shower". Now, when you open the hot valve, you can add cold water until you get the desired temperature. Use the ball valve to shut off the flow without readjusting the temperature. When the hot water is almost entirely consumed, the water will gradually become colder.
    Was this step helpful? Yes | No | I need help

Another Heater

  1. 1
    You will need two PVC pipes; you can also use drainpipe.
    It doesn't involve pressure on the pipe, but instead this is used to collect dust. There is no need to paint the pipe. Clamp both pipes together on a board. On the other end of the pipe, you supply water to it. If you need to add a tap, you may purchase reducer fittings. For increased flow, you may use ¾-inch pipe.
    Was this step helpful? Yes | No | I need help

  2. 2
    A tee can feed the pipes with water.
    Use a tee to provide cold or hot water for the shower. This heater can hold more water than the coil. When you run out of flowing water, set up a 12v utility pump. It has less exposure to sun, so it will take more time to heat the water. You may add a water filter to remove debris. You may use wash machine hoses, or female to female connectors, because you may have problems connecting the male ends.

Questions and Answers

How to make a small water heater?

I live in a hostel where boilers and other stuff are not allowed. I need a small rod or small heater enough to make noodles. I don't like hostel food

To cook, you need a heat source like a hot plate to put a pan of water on. You could order one from an outdoor supply store what are called MREs or Meals Ready To Eat however I would caution that your hostel food may be better than the MREs.

How do I make a water heater using equipment available at home?

I have to do my science project in a week on a homemade water heater that uses batteries.

Stinkadoodlepie on YouTube makes a small water heater using batteries here. You will need an AA battery, ear buds, scissors, electrical tape and a corncob holder. Be careful though, as you will create a full electrical circuit and could shock yourself.
