How to Get Endless Hot Water Off the Grid

Estimated reading time: 6 minutes

How to Get Endless Hot Water Off the Grid

When the grid goes down, one of the first comforts people miss is hot water. It's easy to take for granted until it's gone, and then suddenly everything from washing dishes to preparing food to basic hygiene becomes a challenge. Knowing how to get hot water without electricity isn't just a convenience in a survival situation, it's a genuine necessity.

Most preppers who think about this problem default to solar water heating, but solar hot water systems come with a significant limitation: they depend entirely on sunlight. Cloudy days, storms, and winter conditions can all reduce or eliminate their effectiveness, which is a serious problem when you need hot water.

There's a better solution for off-grid hot water that works in any weather, at any time of day, and requires no electricity, no solar panels, and no propane. It's called thermal siphoning, and it's actually the same basic principle people used to heat water long before modern plumbing existed.

All it requires is a fire, a coil of copper tubing, and a water container. Once it's running, it can heat a 40-gallon tank in roughly 30 minutes using nothing but scrap wood.

This idea comes from the YouTube channel Engineer775, where the host demonstrates how to build and operate a DIY thermal siphon water heater using mostly salvaged and inexpensive materials. You can watch his video and read the instructions below.

What You'll Need

  • A rocket stove or small wood-burning stove with a chimney
  • A large water storage container (a salvaged 40-gallon water heater works perfectly — people throw these away all the time)
  • Copper tubing, ideally 3/8 inch diameter or larger (upgrading to 1/2 inch tubing will increase your hot water output by roughly 40%)
  • Stovepipe to house the copper coil inside the heat chamber
  • Two pipe fittings to adapt the stovepipe connections
  • A shut-off valve and a check valve
  • Standard water pipe or hose to connect the container to the coil
  • Wood fuel

How Thermal Siphoning Works

Before getting into the build, it helps to understand the principle behind it, because once you do, the whole setup makes more sense.

When water gets hot, it becomes less dense and naturally rises. When it cools, it becomes denser and sinks. A thermal siphon exploits this property to move water without any pump or electricity. Cold water enters the bottom of a heated coil, warms up rapidly, becomes buoyant, and rises up through the coil and out into the top of your storage tank.

As that hot water exits, it pulls more cold water in from the bottom of the tank, creating a continuous circulation loop driven entirely by heat. The bigger the temperature difference between the incoming cold water and the heated coil, the faster and more vigorously the siphon pumps.

How to Set It Up

Start by positioning your stove and water container near each other. The water container should be elevated slightly above the stove if possible, as this helps the thermosiphon circulate more efficiently.

Bend your copper tubing into a coil that fits inside your stovepipe. Engineer775 has a separate video demonstrating how to bend copper tubing using ice or sand to prevent it from kinking. It's worth watching before you attempt this step.

Once your coil is shaped, drill two holes in the stovepipe on opposite sides, one near the bottom for the cold water inlet and one near the top for the hot water outlet, and feed the ends of the coil through. Adapt the stovepipe fittings down to match your copper tubing diameter and seal the connections so heat doesn't escape.

Connect the cold water inlet at the bottom of the coil to the drain valve at the bottom of your water storage tank using your water pipe or hose. Install a shut-off valve and a check valve on this line. The check valve is important as it prevents hot water from flowing back the wrong direction.

Run the hot water outlet from the top of the coil back up to the top of your water storage tank. This is where the heated water will return after passing through the coil.

Inside the stove, position a small diffuser plate just above the coil to keep the heat concentrated in the coil chamber rather than letting it all escape up the chimney. This significantly improves heat exchange efficiency.

Operating the System

Fill your water storage tank with cold water before lighting the fire. Once the tank is full, get your fire going and let the stove build up heat. You're aiming for a temperature of around 500–560°F at the coil. At those temperatures, the water exiting the coil will be close to 180°F, which is hot enough to produce visible steam and will absolutely burn you if you're not careful.

Once the stove is up to temperature, open your shut-off valve to allow water flow. From this point, the thermal siphon takes over automatically. You'll hear gurgling as the hot water rises through the coil and pumps into the top of the tank, pushing cold water down and out through the bottom inlet.

The whole tank shakes slightly as the siphon runs, but that's normal. With a good fire going, you can heat a full 40-gallon tank in approximately 30 minutes.

As the tank water temperature rises over time, the temperature differential between the incoming water and the coil decreases, which slows the siphoning rate. This is normal behavior and not a problem in practice. By the time it slows down, you'll already have plenty of hot water.

One important caution: if you run the fire long enough with a sealed tank, pressure will build. Most salvaged water heaters have a pressure relief valve (also called a pop-off valve) that will activate before things get dangerous, but be aware of this and don't leave the system completely unattended for extended periods.

Getting More Output

The version Engineer775 demonstrates uses 3/8-inch copper tubing, which works well but leaves room for improvement. Upgrading to 1/2-inch copper tubing increases the surface area inside the coil by roughly 40%, which translates directly to faster heating and more hot water output. This is a worthwhile upgrade if you're building this system for serious long-term use.

You can also mix the output water with cold water to bring it down to a usable temperature for showering or washing. At nearly 180°F, the output is too hot to use directly on skin, but blended with cold water it becomes a very practical hot water supply.

A Note on Water Safety

If you plan to use any of this hot water for cooking, drinking, or food preparation, be sure to treat it first. The thermal siphon process heats the water but does not filter or purify it.

If your source water is from a questionable supply, boil it separately or run it through a filter before consuming it. For laundry and dish washing, the water coming straight from the system is more than adequate.

Drought: How Will It Affect Our Food Prices?

Drought Agricultural

Drought: How Will It Affect Our Food Prices? This post deals with what every American family needs to know about the coming food cost crisis across the United States. Drought conditions are intensifying in ways that scientists and farmers say haven’t been seen in a generation. Rivers are running low. Reservoirs are shrinking. Fields that once yielded bumper crops are cracking under a relentless sun. And while the images of parched earth are striking on their own, the consequences of this drought will reach far beyond the farm. They’ll reach your grocery cart.

This post explains, in plain language, how the ongoing drought in the USA will affect the price and availability of the food your family eats every day, from the fresh produce section all the way to the cereal aisle.

Drought With Little Boy

Understanding the Drought and Why It Matters for Food

The United States relies on a handful of key agricultural regions to feed the majority of the country. California’s Central Valley produces more than a third of the nation’s vegetables and two-thirds of its fruits and nuts. The Great Plains supply enormous quantities of wheat, corn, and sorghum. Texas and the Southeast are home to vast cattle ranches and poultry operations. When drought grips these regions simultaneously, the ripple effects move quickly through the entire food supply chain.

Drought doesn’t just reduce what farmers can grow. It raises the cost of growing it. When water becomes scarce, farmers pay more for irrigation. Then pastures dry up, and ranchers pay more to feed their animals. When crop yields fall short, food processors pay more for the raw ingredients they need. Every one of those extra costs eventually shows up as a higher price on the shelf at your local store.

Fresh Fruits and Vegetables: The First to Feel the Impact

Fresh produce is among the most water-intensive food we grow, and it’s typically the first place families notice price increases during a drought. Crops like lettuce, tomatoes, strawberries, almonds, and avocados require enormous volumes of water at precise times during their growing cycles. When that water isn’t available, growers face a difficult choice: pay a premium for whatever irrigation water remains, reduce their planted acreage, or walk away from the crop entirely.

Smaller harvests mean fewer food products arriving at grocery stores and farmers’ markets. Basic supply and demand take over from there. When there are fewer strawberries to go around, the price of each pint goes up. When lettuce heads are in short supply, salad bags get smaller or cost more. Families who rely on fresh fruits and vegetables as a cornerstone of healthy eating may find their grocery bills climbing steeply, and may need to consider substitutes or seasonal alternatives to keep costs manageable.

Nuts, a major California export, are especially vulnerable because nut trees like almonds and pistachios can’t simply be left unwatered for a season. They require consistent irrigation year-round, or they die, meaning growers must either find the water at any price or risk losing trees that took years to mature. That long-term investment pressure pushes nut prices higher and keeps them there long after a single dry year.

Meat Prices: Beef, Pork, and Chicken Under Pressure

Raising animals for food is one of the most water-intensive activities in agriculture, and drought affects the meat industry in several ways at once.

Beef

Cattle ranching is deeply tied to the health of rangeland grasses and hay fields. When drought burns those pastures dry, ranchers can’t graze their herds the way they normally would. Buying supplemental feed becomes an immediate and expensive necessity. Many ranchers, faced with the cost of feeding animals on dry land, choose to sell off portions of their herds early rather than take on that expense. This creates a short-term surge in beef supply that can temporarily push prices down, but it’s followed by a significant and lasting price increase once the herd has been reduced and there are fewer cattle to go to market in future months and years. American families should be prepared for beef prices to rise substantially and remain elevated for an extended period.

Pork

Hogs are raised largely on corn and soybean feed. When drought reduces corn and soybean harvests, the cost of that feed rises sharply. Pork producers absorb those higher feed costs for as long as they can, but eventually pass them along to grocery stores and restaurant suppliers. The result is higher prices for pork chops, bacon, sausage, and every other pork product that families depend on. Because the pork production cycle moves faster than beef, these price changes can appear on store shelves relatively quickly after a major drought year.

Chicken

Poultry is often considered the most affordable meat option for families on a budget, but chicken prices aren’t immune to the impacts of drought. Like pork, chicken production relies heavily on corn and soybean feed. When drought drives those grain prices up, chicken producers face the same cost pressure as pork producers. Chicken wings, breasts, thighs, and whole birds all become more expensive when the grains that fuel poultry growth become scarce and costly. Families who have turned to chicken to keep their grocery bills in check may find that option less affordable than it once was.

Dairy Products: Milk, Cheese, Butter, and Yogurt

Dairy farming requires a remarkable amount of water. A single dairy cow can drink between 30 and 50 gallons of water per day, and that number climbs higher in hot drought conditions. Dairy operations also need water for cooling systems, cleaning equipment, and irrigating the feed crops that sustain their herds. When water becomes scarce and expensive, dairy farmers face higher operating costs across the board.

Beyond water access, drought affects dairy production by impacting feed. Alfalfa, which is one of the primary hay crops fed to dairy cows, is extremely water-intensive. Reduced alfalfa harvests mean higher prices for that hay, which translates directly into higher costs for dairy farmers. Some operations scale back their herds when the economics become too difficult, reducing the overall supply of milk entering the market.

Families can expect to see the effects in the dairy case, with higher prices for milk by the gallon, shredded and block cheese, butter, sour cream, and yogurt. Because so many everyday recipes and meals depend on dairy products, these price increases have a broad effect on overall household food budgets.

Processed Foods: The Hidden Drought on Your Pantry Shelves

Many families may assume that processed and packaged foods are insulated from drought because they don’t come directly from the farm. In reality, the opposite is often true. Processed foods are built from agricultural ingredients, and those ingredients face the same supply pressures that affect fresh produce and livestock.

Corn syrup, soybean oil, wheat flour, and dairy solids are the backbone of many processed foods. When drought squeezes the supply of those raw ingredients, food manufacturers pay more for them and adjust their product prices accordingly. Canned soups, frozen meals, snack foods, condiments, sauces, and packaged side dishes all become more expensive as the ingredients they contain become harder to source and more costly.

In some cases, manufacturers may also reduce the size of their product offerings rather than raise the price on the label. This practice, sometimes called shrinkflation, means that families get less food for the same amount of money. Paying attention to unit pricing rather than the total price can help households spot this kind of subtle change at the store and make buying decisions based on the actual prices they pay.

Please Stock Up On Canned Goods ASAP

Cereal: A Breakfast Staple Under Strain

Breakfast cereal is one of the most widely consumed pantry staples in American households, and it is deeply dependent on the grain harvests that drought threatens most directly. Corn, wheat, oats, and rice are the primary grains used in cereal production. Each of these crops requires significant rainfall or irrigation during the growing season and is vulnerable to sustained water stress from drought.

When wheat harvests fall short on the Great Plains or corn yields disappoint in the Midwest, cereal manufacturers face rising costs for their most essential raw material. Those costs are passed on to the consumer in the form of higher per-box prices. For families who rely on cereal as an affordable and convenient breakfast, this is a meaningful budget concern.

Oats, which are a primary ingredient in granola and oatmeal products, face similar pressures. Drought-stressed oat fields produce smaller kernels and lower yields. The increasing popularity of oat-based products, including oat milk, oat flour, and oat-based snack bars, is adding to demand on a supply already strained by drought.

Packaged Goods Made with Flour and Sugar

Flour and sugar are two of the most fundamental ingredients in the American food supply, and both face significant drought-related pressure.

Wheat flour, which is used in bread, pasta, crackers, cookies, cakes, muffins, tortillas, and countless other products, comes primarily from hard red winter wheat grown in drought-prone regions of Kansas, Oklahoma, Texas, and the surrounding states. When dry conditions damage wheat crops, the price of flour rises at the mill and eventually rises at the store. Every product made with wheat flour becomes more expensive as a result.

Sugar presents a more complex picture. The United States produces sugar from both sugarcane, grown primarily in Florida, Louisiana, and Hawaii, and sugar beets, grown in drier inland states where drought risk is real. When either crop is compromised by insufficient water, the domestic sugar supply tightens. Combined with global sugar market pressures, this can push the price of sugar-containing products noticeably higher.

Consider how many items in a typical grocery run include flour or sugar: bread, rolls, sandwich wraps, pasta, boxed macaroni and cheese, cake mixes, brownie mixes, cookies, crackers, granola bars, frozen pastries, pancake mix, and more. A sustained increase in the price of these two ingredients casts a wide shadow across the entire packaged foods section of any grocery store.

How Long Could These Price Increases Last?

One of the most important things families should understand about drought-driven food price increases is that they don’t always go away quickly when rain eventually returns. Some effects are short-term, tied to a single bad harvest that corrects itself the following year. But others are longer-lasting.

Cattle herds, once reduced, take several years to rebuild to previous levels. Fruit orchards and nut groves that are abandoned or damaged by drought could take a decade or more to replace. Aquifers and groundwater supplies that’ve been depleted over years of drought don’t refill after a single wet winter. These structural effects mean that some food prices, particularly for beef and certain fruits and nuts, could remain elevated for years even after drought conditions improve.

Climate scientists have also noted that the western United States is entering a period of what they call aridification. This long-term drying trend goes beyond any single drought cycle. If this trend continues, the regions that grow much of America’s food will face increasingly persistent water challenges, suggesting that food price pressure could become a regular feature of the grocery experience for American families rather than a temporary crisis.

What Families Can Do to Prepare

While no family can stop a drought, there are practical steps households can take to stretch their food budgets and minimize the impact of rising prices.

Shopping seasonally and locally remains one of the best ways to find fresh produce at lower prices. When a crop is in peak season in your region, there is typically more of it available, and it costs less. Getting to know what’s in season in your area and planning meals around those ingredients is a time-tested way to eat well for less.

Expanding the range of protein sources your family enjoys can also help cushion the impact of rising meat prices. Beans, lentils, canned fish, and eggs are all nutritious and relatively affordable protein options that are less directly affected by livestock feed cost pressures. Incorporating more of these alternatives into weekly meal planning can help balance a budget squeezed by higher beef and pork prices.

Buying in bulk and stocking up on staples when prices are lower is another useful strategy. Flour, sugar, dried beans, canned goods, and frozen vegetables often go on sale, and purchasing extra when prices are favorable can help families ride out periods when drought-driven price increases hit hard.

Home gardening, even on a small scale, can provide meaningful amounts of fresh produce during the growing season. Tomatoes, herbs, green beans, and salad greens can be grown in modest garden beds or even in containers on a patio or balcony. The investment in seeds and soil mix is small compared to the grocery savings over a full summer season.

Finally, reducing food waste is one of the most powerful things a household can do to stretch a food budget under any circumstances, but especially during periods of rising prices. Planning meals before shopping, using leftovers creatively, and properly storing produce to extend its life are habits that can make a real difference in how much a family actually spends on food each week.

The Bottom Line for American Families

Drought isn’t just a problem for farmers. It’s a problem for every family that buys groceries, which is to say every family in America. The water shortage unfolding across large portions of the United States is setting in motion a chain of events that’ll push up the cost of fresh produce, raise prices at the meat counter, increase dairy expenses, and drive up the cost of the cereals, breads, packaged snacks, and processed foods that fill our pantries and feed our children.

Is There a Water Shortage Where You Live?

Pork: Everything You Need to Know

Final Word

Understanding how drought connects to food prices is the first step in preparing your household for what’s coming. The families who come through this challenge most successfully will be those who plan ahead, shop smart, reduce waste, and find creative ways to keep nutritious and delicious meals on the table even as ingredients cost more. The drought may be happening far away in sun-baked fields and depleted reservoirs, but its effects are on their way to your kitchen. Knowing that, and acting on it, is something every American family can do right now. May God bless this world, Linda

Here’s How to Recycle Gold and Copper from Old Electronics

Some people actively prospect for gold and other precious metals across rivers, creeks, and streams. Images of Alaska Sourdoughs and California 49ers come to mind as they swirl their gold pans in freezing waters and look with hope for a speck of gold.

But you don’t have to head for them thar’ hills to find gold and other precious metals. It’s all around us if we know where to look.

The Circuit Board Source

Many circuit boards use gold across their surfaces. Gold is an outstanding electrical conductor, and it is frequently used on circuit boards for computers, cell phones, TVs, radios, and other high-end electronic devices.

On a side note, older electronics often have more gold on their circuit boards due to the historically lower price of gold in the past. We’re going to cover the process and techniques for harvesting the gold, other metals, and specific electronic and electrical sources.

Why Bother?

The reason is simple. The spot price for one ounce of gold as of this writing is $5,197 USD per ounce and climbing. Even if you’re only able to harvest a ¼ ounce of gold, that’s more than $1,000. But it doesn’t stop with gold.

Copper Possibilities

Copper is everywhere! While it’s not as precious as gold, copper prices are already rising worldwide. The spot price for one pound of copper as of this writing is close to $6 USD a pound. That’s nowhere near as valuable as gold, but copper sources are much easier to find in greater quantities.

👉 Your Stockpile May Be Worth More than Your Savings Account 

This includes copper wire bundles surrounding electric motors, copper pipes, electrical wires, copper cables, and even copper pots. You may be lucky to harvest a ¼ ounce of gold, but you can easily find pounds and pounds of copper.

We’ll cover some of the tips and tricks to make copper harvesting easy.

Where Can You Sell it?

Copper can be sold at junkyards and scrap yards. There are various grades of copper, so make sure you sort your copper so they don’t average everything down to the lowest price grade. We’ll also cover how to identify those grades.

Gold can be sold at pawn shops and stores that often feature large signs proclaiming, “We buy gold!” Most of them buy gold jewelry or coins, but they can test small gold bars or chunks to determine the gold content. There are lots of videos on the Internet about how to melt down gold into small ingots or pieces.

Gold Is Also Graded

It comes as a surprise to some, but gold found in nature is rarely 100% or 24 karat gold. It is often an alloy of gold, silver, copper, and other native metals. The average gold nugget found in North America is about 60% gold with silver as the primary alloy. On the other hand, Australian gold found in mines and creeks can be as high as 90% gold!

This Common Metal Will Be More Valuable than Gold When SHTF

The gold you harvest will probably have a high percentage of gold up to 90% or more, but some traces of solder or other metals on a circuit board can find their way into the mix. That’s important to know.

When the gold dealer tests your gold and quotes you a price less than you expect, they may be very accurately telling you its actual worth based on the final gold percentage.

Safety First

Harvesting and salvaging copper is pretty straightforward and mostly involves dismantling motors, stripping wires, and sawing up copper pipes. From a safety standpoint, leather gloves are a wise idea, especially around the sharp parts of a motor armature surrounded with copper wire.

Gold harvesting from circuit boards is another story. It often involves the use of nitric acid. That’s dangerous. Nitrile gloves, a face mask, goggles, and even a full face shield are a good idea, along with a long sleeve shirt.

👉Homemade Golden Milk for Inflammation & Stiff Joints

There’s another method that takes longer and is a little more labor intensive, using white vinegar, salt, and hydrogen peroxide. It’s much safer but takes a couple of days, and you may have to physically scrape off some of the gold.

You’ll also need some tin snips to cut apart the circuit boards. We’ll cover safe handling instructions, but if you are hesitant about nitric acid, stick with the copper salvage or the white vinegar approach to gold.

Circuit Board Prospecting for Gold

There are a number of sources for circuit boards. Some have more gold than others. Here are the sources to consider:

  • Computers.
  • Cell phones.
  • TV’s.
  • Radios.
  • Any CPU (Central Processing Unit).
  • Appliances with Smart Electronic Features.

Getting to the circuit boards requires taking the equipment or appliance apart. You’ll need some tools, including screw drivers, socket wrench and sockets, pliers, wire cutters, needle nose pliers, and leather gloves.

The circuit board is usually a central feature inside computers, cell phones, and radios. You’ll also need to look a little harder for it in large TV’s and appliances.

The CPU chips in everything are often loaded with gold, so don’t miss it.

The same is true for RAM boards that often have a long row of gold at the bottom of the board. The whole idea is to use tin snips to cut out the parts of a circuit board that have gold inlays.

You don’t need to immerse the whole board in dilute nitric acid, just those parts that contain gold. And always remember to do your circuit board processing in a well-ventilated area or ideally outside.

The Nitric Acid Method

You’ll need some equipment and supplies to remove the gold from the circuit boards and CPUs. 

Tools & Supplies

  • A large glass beaker or a large Pyrex glass bowl.
  • Enough nitric acid to fill half of the glass container (some jewelry/refining supply stores sell it – check your local regulations first).
  • Coffee filters.
  • A glass stirring rod.
  • A fine mesh strainer.
  • A bucket of water.
  • Tin snips for cutting gold parts from circuit boards.
  • Safety gear, including gloves, safety glasses or goggles, apron and a face mask. You can find a complete safety kit on Amazon for around $30. 

How to Do It

  1. Use the tin snips to carefully cut out the gold-bearing parts of the circuit boards. The acid is going to melt the plastic parts of the board, leaving the gold behind.
  2. Add nitric acid to your glass beaker or bowl until it is half full.
  3. Carefully drop the circuit board parts into the acid one at a time.
  4. Stir the mixture carefully with the glass rod until the non-gold components have dissolved.
  5. Carefully pour the contents of the beaker or glass bowl into a bucket of water. You can acid to water. Never add water to acid. It will violently flash. Always add acid to water. Remember: “AAAW.” You’re doing this to dilute the acid, so it won’t dissolve your strainer or the filters.
  6. Pour off some of the water into another bucket of water, making sure that the gold flakes remain in the bottom of the bucket.
  7. Carefully strain the water/acid and gold mixture through a fine mesh metal strainer lined with a coffee filter.
  8. You should see the gold flecks on the coffee strainer.
  9. Pick out the gold flecks as much as possible and remove any remaining plastic or debris.
  10. Collect your gold in a small glass vial.

Harvesting Gold: The Acetic Acid Method

Banner with a blurred picture saying Watch Now and the headline This Common Weed Hides Gold Nuggets (and it's probably in your backyard)Cleaning vinegar is diluted acetic acid. Most store-bought vinegar is a 5% dilution intended for meals.

There is another vinegar solution usually sold in home centers in the cleaning aisle. It is a 30% dilution.

It’s not suitable for human consumption, but the concentration works better for dissolving circuit boards.

The overall process takes longer but is much safer.

Here’s the equipment and supplies you’ll need:

When it comes to the actual process, it’s important to take all the safety measures possible. Also, for proper results, make sure you don’t skip any of these steps:

  1. Use the tin snips to carefully cut the gold parts from the circuit boards
  2. Fill the glass bowl or jar half full with the 30% vinegar (acetic acid)
  3. Add 2 tablespoons of sea salt and stir to dissolve
  4. Add the gold chips from the circuit boards
  5. Carefully pour one cup of hydrogen peroxide into the mixture
  6. Let the boards soak for 48 hours, stirring occasionally
  7. Look for the gold foils separating from the circuit board pieces
  8. Use a fine mesh strainer to strain the gold foils from the solution
  9. Pick out the plastic bits with tweezers, leaving the gold foil
  10. Strain through a coffee filter and gently rinse under distilled water
  11. Let them dry completely, scrape off the gold, and collect in a small glass vial

Be Patient

The acetic acid process with white vinegar won’t dissolve the plastic as much, but it will release the gold pieces from the plastic parts. You might have to do some peeling and stirring to shake all of the gold loose.

These 17 U.S. Towns Are Giving Away Free Land. Here’s How to Claim It!

It’s hard to say how much gold you’ll end up with. It depends on how many circuit boards you started with and the amount of gold on each one. Over time, you can continue this harvest.

If you want, you can dumpster dive behind electronics stores where they sometimes discard old or defective electronics. You can also inform friends and family that you’ll take any old electronics they plan to throw away.

Copper Salvaging

Salvaging copper is much safer and easier to find. That’s good because copper is nowhere near as valuable as gold, but you can easily make a decent amount of money with copper salvage.

Here are some sources to consider:

  • Armatures from old motors from washing machines, dishwashers, dryers, furnaces, and other appliances wrapped in copper wire
  • Copper coils from air-conditioners, refrigerators, dehumidifiers, and other appliances work through condensation
  • Copper plumbing pipes and fittings
  • Copper wire and cables
  • Old Copper kitchen utensils found at flea markets or resale shops

The the equipment and supplies you’ll need for copper extraction includes:

The 3 Grades of Copper

better than goldThe copper you salvage will be evaluated on its grade or purity.

Here are the 3 grades to look for as you salvage (make sure you place each grade in its own bin for when you take it to the salvage yard):

  • Grade 1: “Bare Bright.” This is salvaged copper that is 100% copper and still shows a bright, copper shine.
  • Grade 2: “Wire/Cable.” Clean, unalloyed copper wire or cable that is at least 98% copper.
  • Grade 3: “Contaminated.” Copper that appears contaminated with solder, paint, roofing tar, or other substances that add weight from non-copper sources. If possible, cut or trim away these parts to upgrade the piece to grade 2 or 1 and toss the contaminated pieces into bin 3.

Another form of contaminated copper is copper that has a patina of green. This is caused by oxidation.

The Statue of Liberty is actually made from copper plates, but the green patina from exposure to oxygen and moisture makes it appear green. The easiest way to clean this green patina is with a combination of vinegar and salt. That will upgrade it from Grade 3 to Grade 1.

Process

Salvaging copper is a straightforward, physical process. No harsh acids are necessary.

Motor Armatures

Motor armatures are a great source for Grade 2 copper. Use wire cutters, tin snips, or needle-nose pliers to cut and pull the copper wire from the armature. Armature designs very so you’ll have to figure out the best way to cut or pull the wire loose. Toss the wires into bin #2.

Copper Condenser Coils

Copper condensation coils from air conditioners, refrigerators and other appliances that condense moisture are an excellent source of grade 1 copper. They are usually free of contaminants and there’s often a significant amount of copper that can be salvaged. Use a hacksaw and pliers to remove the copper or loosen any fitting holding the coils to the unit.

Copper Plumbing Pipes and Fittings

Copper plumbing pipes and fittings are another excellent source for Grade 1 copper although the pipe ends and fittings are often contaminated with solder, putting them at Grade 3.

Trim off and isolate any contaminated parts.

Most of the copper will be Grade 1 and you don’t want to downgrade the value because there’s a little solder on the ends of the long copper pipe.

Copper Wire and Cables

The approach to harvesting copper from wire and cables is logical. The larger the gauge of the wire or cable, the easier it is to harvest more copper.

Stripping smaller wires and cables is up to you. It’s an easy way to pass the time if you have it, but larger wires and cables are more profitable. All would fall in the category of Grade 2.

Copper Pots, Pans, and Utensils

Grid Phantom - AI Defense SystemCopper pots, pans, and utensils are usually 99.9% copper. That would easily put them in Grade 1.

The big question is, do you want to give up your cookware for salvage?

An easier decision is old copper cookware that you buy at a flea market or resale shop. Look for the pieces that are dented or somehow damaged.

They should be cheap and the salvage value might exceed the price. That’s the key. Is it worth more to a junkyard than to you?

All It Takes Is Time
