Heat Cable Systems


Our heat cable has an output of 2 watts per foot. One cable will give good performance to about 20. Two cables installed in the same pipe will give protection to about 0. If two cables are required for your climate, install two cables, putting one on a thermocube and operating the other manually. This prevents both cables from coming on at the first drop in temperature, thus saving electricity. This is the cable we used in our rabbitry and has been installed throughout the nation with good results. Operates on 110 volts. See diagrams on previous page for installation suggestions.
CAUTION: Heat cables can NOT be spliced or cut! Please read entire instruction sheet and wiring diagram sent with each cable.
Compression Fittings
For routing heat cable through water lines in a closed pressure system. 
Includes two-part brass body, cotton packing and instructions. For low pressure only (1-10psi max.)

The heat cable is a solid copper resistance wire with a braided copper lead wire. 
The resistance wire can not be shortened or lengthened because each spool is engineered to create the right amount of heat from the resistance in that given length. 
The cable is made to install inside the PVC water line. 
They work best if the lead wire is not submerged under water, just the heat cable wire. 
The customer would need a 110 plug to wire to the heat cable. 
The cable needs to make a loop so that both lead wires can be wired to this plug. 
You can lengthen or shorten the lead wires as needed, just not the heat cable wire. 
The heat cable does not need a controller, it is just an on/off product. 
We recommend the thermo cube to go along with the heat cables. It just automates things a little, by plugging the heat cable into this it will kick on/off with the temperature of the room. 
When using the the compression fittings you may need to cut the wire were the to wires join to allow it to pass through the fitting. 
Then reconnect after it is pulled through the fitting. 
Once it is through the fitting you pack the cotton string in the base a tighten the cap to compress the string around the cable.
