12 volt 100 watt, 12 volt 200 watt or 24 volt 600 watt water heating coil

Use direct from solar panels or as a diversion load with diversion regulator

12 volt and 24 volt water heating coils. We have the 12 volt coils available in 100 watt or 200 watt. The 24 volt coils are 600watt each. These coils are made to fit standard water heating threads. They have 1" threads. Use them with our diversion regulator to pull the excess power from your batteries and heat water.

They can also be used direct from a battery to heat water when camping or they can be used directly from solar panels. See instructions below.

Many farmers are using these coils to heat their stock tanks and avoid chopping ice in the winter. We also have adapters that can be used to fit these coils in to barrels and drums.

During the summer months it may take 1-2 weeks for us to ship the water heating coils as our supplier does not keep as many of them in stock during the warmer summer months.

If you plan to use two be sure that you order the multi regulator.

How to connect water heating coil

CAUTION! Be sure that the coil is always in water when it is heating to prevent the coil from failure.

This water heating coil is made to fit most standard water heaters. If you are using with another type of container such as a barrel or stock tank we also have a 2” coarse threaded adapter fitting that can be used along with the water heating coil.

Simply attach the positive line from the panels, diversion regulator or batteries to one bolt connector and the negative line from the panels or batteries to the other bolt connector.

If you are using solar panels you can go direct from the panels to the water heating coil.

If you are using wind generators you must take the power from the wind generator to batteries first. The wind generators will put higher voltage than the coil can handle and it will burn out the coil. Run the power from the wind generators to the batteries and then use a diversion regulator to shunt the power to the coil. You can run direct from the batteries but there will be nothing in place to keep the batteries from completely draining. If you are out camping and simply want to use a battery to run the water heating coil to heat water and do not care if the battery drains you can run direct from the battery.
