Cable—For outdoor frames or greenhouses where heating cable is 
buried in the soil but the surrounding air is not heated by other 
means, approximately 10 watts per square foot of surface area is 
required. 
In greenhouses etc. where the air as well as the scil is heated, 
approximately 5 watts per square foot has been found adequate. 
Heating cable is rated 6-2/3 Watts per lineal foot. It must be used 
in multiples of 60 ft. 
60 ft. cables 400 Watts 110 volts 
120 ft. cables 800 Watts 220 volts 
240 ft cables 1600 Watts 440 volts 
Therefore a bed with soil heating only, with area of 160 square ft. 
should be heated as follows: 
160 sq. ft. times 10 watts/sq. ft. == 1600 watts
