Buy a 12 pack now!

GREAT FOR DIVERSION LOADS: Most electric hot water heaters have two element ports. One in the middle and one at the bottom of the tank. Use your WH series element to replace the bottom 240 VAC element so you always have hot water. If your battery is keeping your water hot then the thermostat on the other 240 VAC element will never turn on unless you run out of wind or solar power. A great diversion load for alternative energy systems!

Don't let the energy efficient 300 Watt rating fool you, all of these elements can easily bring small amounts of water to a full boil.

Note: If you have a gas hot water heater you may wish to put an electric unit ahead of it. This way the gas heater is always being fed hot water so it does not turn on as often and for shorter periods of time when it does.

GREAT FOR MANY USES: Great for campers, motor homes, toy haulers, hot food carts, catering, portable pressure washers and carpet cleaning machines, make hot water while you drive! Take a hot shower while tent camping or after surfing or scuba diving. Make emergency hot water for hypothermia or frost bite victims in the field. For cattle and live stock, keeps water troughs and stock tanks from freezing in winter. Just too many applications to mention. People have found hundreds of very beneficial and unusual uses for our powerful and portable 12 volt water heaters. (Also available in 24 and 48 volt models, see below)

FOR INDUSTRIAL USES: We have been helping thousands of concrete mixing trucks and concrete cutting saw business for a long time! Frozen water can put your crew out of business for the day! Use one or two elements depending on the size of the tank. DO NOT leave the tanks filled over night!!!! Fill them with fresh water in the morning and then keep the heating element running in the tank all day long and your water will never freeze. Over 9000 work trucks use them now.

WARNING: Do not run the tanks DRY with the heating element ON or it will burn up!

NOTES FOR ANIMAL AND BASIC LIVE STOCK SAFETY

Remember NEVER to heat your animals water with a high voltage 110 Volt heaters as this practice regularly kills

an estimated 17,000 animals annually once the high voltage heater gets a crack in the electrical insulation material!

NOTE: Only use Low Voltage heaters like ours that run on battery power or operate from a low voltage power sources like a 50 amp battery charger.

"Swopping out a battery daily sure beats chopping ice everyday"

Keep remote stock tanks from freezing solid with our #SJH series water heaters!

People have found that using our battery powered heaters is the BEST deicing method

ever devised! Keep water available to your live stock 24 hours a day. While the 12 volt

battery needs to be changed out ONCE a day it sure beats chopping ice 3 or 4 times a day!

Compared to endless ice chopping simply swapping out batteries once a day is relatively easy!

(You can also use much bigger batteries and go as long as 4 days. For more info read all info below)

Threads right into the bottom of all 1" water tank drain plugs. (1" NPT - bottom tapped)

For SMALLER stock tanks from 25 to 50 gallons use one of our 600 Watt models. Recommended for temperatures between 32 and 20 degrees F.

For LARGER stock tanks (50 to 100 gallon) use dual 600 Watt models. Recommended for temperatures between 32 and 15 degrees F.

For LARGER stock tanks (75 to 150 gallons) use triple 600 Watt models.

Recommended for temperatures between 32 and 15 degrees F.

Use our 600 Watt models in VERY cold weather -

Recommended for temperatures between 32 and -0 degrees F.

Use one heater for every 25 gallons in water volume.

Use our 300 Watt models in mildly cold weather when it only freezes at night

ranchers may consider using our 300 watt models. This works well when daytime

temperatures are above freezing but night-time temperatures drop no lower than

20 degrees F. for water volumes no larger than 15 gallons.

NOTE: Some tanks have a larger drain hole than 1". In this case you

must buy a threaded reducer bushing at your local plumbing supply store.

IMPORTANT HINTS:

These heaters only work on insulated type water tanks! Insulate the water tank by applying a spray-able urothan foam type insulation. This is very important to stop heat dissipation!

The foam should be 4" to 6" thick! Also the battery powering your heater should be placed in a closed box with at least 4" of foam insulation to keep its power levels higher in cold weather.

Note: Large tanks should be sitting on solid Styrofoam billets that are at least 6" thick. The ground is very COLD!! If your local lumber only has 1" thick Styrofoam use it 6

layers deep! This is very important. Tanks with no insulation are very difficult to heat. Wind chill makes it even worse. Building a small wood shelter for your water tank may

also be very helpful in very cold areas.

OPTIONAL FREEZE AUTOMATION-

Thermal-Q ® - Freeze Sensors work great for all low voltage battery applications.

The Thermal -Q Freeze Sensor
Our handy Thermo-Q freeze sensor will automatically turn power "ON" when the water temperature reaches 35 degrees F. and will turn off the power when the
water temperature exceeds 50 F. degrees. This effectively keeps water from freezing. The Thermo-Q unit can be used with any other ANTI-FREEZING devices to save electricity and or prevent over heating. Works great for all low voltage and battery powered heaters. Works on 12, 24 ,36 and 48 volt systems, 25 amps max. Good for 300 watt heaters only.

(The 50 amp or 600 Watts sensors are not avalible for sale. We only sell them as a kit! If you use multiple 300 watt heaters you will need one Thermo-Q freeze sensor per heater!!)

Characteristics:

At 35 degrees F. the Thermo-Q will turn "ON" all types of heaters: Heat tape, heat lamps, stock tank heaters, pond heaters, engine block heaters, etc.

Can also be used as a "Freeze Warning Device" by connecting it to a car head lamp that is visible from your house. The Thermo-Q can simply be used to light-up a lamp or alarm if the temperature drops below 35 degrees F. alerting you. 300 Watts peak!

PROBLEM SOLVING; The pipe thread seems too tight!

In some cases it is a tight fit depending on how deep the manufacturer of the FEMALE receptacle tapered their thread cut in the pipe hole.

A water heater element style 1" national pipe thread (NPT) has a radical taper to it. Since the thread is so short on the heater the taper is at its maximum pipe O.D. already. This prevents leaks but it may also cause the thread to be very tight and hard to get started in some holes that are not fully tapered by the manufacturer.

SOLUTION; If you take a 1" NPT pipe tap and make the hole taper just a hair larger and then your heater will spin right in. You can also take a 1" pipe die and cut a little off of the heater threads too.

Ohm's Law Calculator

Q. - CAN I CONNECT ONE OF THESE 12 VOLT HEATERS DIRECTLY TO MY WIND TURBINE?

A - NO!!! It will burn up in a wind storm since the heater may see voltage levels 5 or 6 times higher than its rating. REMEDY- You need to use a very small 12 volt motor cycle battery in parallel as a buffer! This will protect the heater from receiving over voltages!!! It must be a lead-acid type battery that CAN BE refilled with water (Do not get a sealed type or a dry cell!!!) Even an old used car battery will do just fine as long as it has a tiny bit of life left, it will still make a good power buffer.

Q. - I have your highest power 600 watt model and a big powerful battery at the full 13.8 volt charge but the water still freezes up by morning. What can I do?

A - You must be in an extremely cold area. The best thing you can do is get a smaller stock tank to concentrate the heaters energy into a smaller body of water. Also try to bring hot water with you when you fill your stock tank. Many ranchers fill their truck-tank directly from their home hot water heater. This water is burning hot at first but by the time you get out to the stock yard the water will be nice and warm and will melt all of the ice in the tank on contact ! (No Chopping). Now connect your freshly charged battery to your stock tank heater and you should be able to make it for a full 24 hours, until your next visit.

Q. Is there any reason why I can't wire my 24 volt Hornet directly to my SJH24 water heater?

A. The reason a 24 volt Hornet can not be directly hooked up to a 24 volt element WHICH must BE run AT ONLY 24 to 30 volts MAX. is
that at about 40 MPH a 24 volt Hornet will actually be putting out about 80 volts and BOOM goes your heater. A battery is necessary to buffer
the wildly varying power output of a wind turbine.

Q. My heater will not screw into the 1" NPT hole on my threaded tank.

A. We use a 1" BOTTOM TAP STYLE thread as it says in all of our ads. FIX - You need to buy or rent a 1" pipe tap and open up your thread ALL the way to the
maximum possible pipe taper so it will fit in the NOW 1" bottom taped threaded hole. Just run the pipe tap through the hole until the threads are fully cut up open to full size (bottom taped) Remember pipe thread is tapered. BOTTOM TAP means ALL THE WAY OPEN to the maximum taper. There is also a TAP called a bottom tap that does this right away. In either case you need to open up your threads wider, then it will fit into your 1" bottom taped hole.

Extending battery time - Batteries can also be banked together in PARALLEL (not series) to extend the time in between visits to remote stock tanks. You can also extend the running time by up to 4 times by using 6 volt "GOLF CART" batteries and running the heater on only 6 volts. On a 6 volt battery they will last 4 times longer in between charges BUT they will not run as HOT either which could work out nice for smaller or really remote tanks!

In any case there are lots of wiring configurations you can experiment with in-order to get the right heating curve and longevity out of your batteries.

You can also use a wind turbine or solar panel to help charge batteries in the field too! Only you can determine what will work in YOUR situation so pay close attention to the water for the first few days your heater is on line!

Why does battery power work so well? Even during the day when temperatures rise above freezing the water is being slowly heated by the water heater.

This large body of warm water acts as a gigantic heat sink (Thermal Mass) and the water will hold that heat all night long, especially if you insulate the tank too!

EXAMPLE: If you have ever unplugged a portable spa you will have noticed that even days later the water is still very warm even in freezing weather. This is why slow heating of water both day and night with a low wattage battery powered heater works out so well.

Questions And Answers

Q. - Will it work on my rubber maid tank and what do you think of solar? Also how do I get maximum battery life in winter the months.

A - It works on most of the rubber maid tanks but you will have to check if it is a 1" pipe thread. Also we use a BOTTOM TAP NPT thread style so sometimes
you may have to re-thread the hole to the largest possible 1" taper but that is easy. I would highly recommend that you go to the smallest tank size possible in the winter months so the heater can do its job. Since the battery needs to be swapped out and the dead one recharged daily most people with 3 horses could get away with just a 20 to 30 gallon tank if re-filled daily. This does not mean you have to remove your big water tank but just offer the live stock an alternative drinking spot that is smaller and still liquid. The problem with solar is that the snow covers the panel so it also needs daily sweeping, The panels also cost about $1800.00 each for the Wattage needed to run the 600 Watt heater and the theft rate on an $1800.00 solar panel sitting in the middle of an open field is about 100% in the first year!

Q. -How does this all work? Please tell me what I need to do.

A. - Most of our customers connect a freshly charged deep cycle battery on their tank heater once every day at feeding time and then they JUST swap them out for a newly charged battery at that time. This means you will need two deep cycle batteries. One is operating the heater while the other one being recharged. No more chopping sheets of ice, battery swapping is all you need to do here. EASY! The water above the heater is always open. Also put straw bails around your tank and set the tank on an 8" bed of straw to keep it off of the cold ground. You can also build a dirt ramp around it for short animals if necessary.

Q. -Why is my battery only lasting 6 hours?

A. - First of all 6 hours of making warm water is very good because it may actually take the water 18 hours or more to cool back down to freezing so you have figure that into the whole timing equation. Having a tank with insulated walls that also is not siting on the ice cold ground will also help extend your warm water time dramatically.

Second, make very sure that you charge your battery up to a full 13.8 volts . This will give you TWICE the power of an ordinary 12 volt charge. This can be done by using a charger that has a "Boost" mode on it and a timer. Set it for 60 minutes on full BOOST mode. Using a charger that has a START/BOOST mode super charges your battery effectively doubling its energy output! Double check the charge with a volt meter and make sure its 13.7 volts or higher. If not, give it 60 more minutes of charging on the start/boost setting.You can also try buy a bigger DEEP cycle battery or even add many batteries in parallel to increase heating time. Insulate your batteries too. A cold battery is a dead battery! The BEST deep cycle battery is a TROJAN model # DC-500ML. This is the battery you should get! ( Rare facts: A 12 volt battery can be charged up as high as 14.7 volts) "Swopping out a battery daily sure beats chopping ice everyday"

Q. - CAN I CONNECT ONE OF THESE HEATERS DIRECTLY TO MY WIND TURBINE?

A - Yes but you must only use a model #SJH24125 heater in combination with the model #HT500/24 VOLT wind turbine! Buy Both as ONLY this combo works! This is the only combo proven not to 'stall-out' the wind turbine from spinning or burn-out the heater in a wind storm.

Q. My heater will not screw into the 1" NPT hole on my threaded tank.

A. We use a 1" BOTTOM TAP STYLE thread as it says in all of our ads. FIX - You need to buy or rent a 1" pipe tape and open up your thread ALL the way to the

maximum possible pipe taper so it will fit in the NOW 1" bottom taped threaded hole. Just run the pipe tap through the hole until the threads are fully cut up open to full size (bottom taped) Remember pipe thread is tapered. BOTTOM TAP means ALL THE WAY OPEN to the maximum taper. There is also a TAP called a bottom tap that does this right away. In either case you need to open up your threads wider, then it will fit into your 1" bottom taped hole.

Q. - I have your highest power 600 watt model and a big powerful battery at the full 13.8 volt charge but the water still freezes up by morning. What can I do?
