Soil Warming Cable

The principal of soil warming cables is the same as that of under floor heating in homes. Depending on the bench size a correct size cable is chosen and buried in coarse sand. When the cable is activated by the built in thermostat it heats the entire mass of sand to the desired temperature. This sand then has huge thermal inertia and therefore stays the same temperature without constantly turning on and off giving better results. The cables are double insulated and have an aluminum internal sheath which allows the cable to be installed with ease. The cables come in 5 standard sizes but custom sizes are no problem.
