Heating Wire

  1. Aug 9, 2010 #1
    I am trying to determine a wire to use as a resistance heater. I want to adhere this wire to the rear of my satelitte dish with aluminum foil tape. I am in the process of designing a temperature and humidity controller to cycle the heaters on and off. I know that I need the heater to produce a temperature between 130°F to 140°F. I plan to power the heating wire with 110Vac.

    The controller will sense the ambient temperature and humidity around the reflector and if the conditions for the formation of ice are present, I want the heaters to turn on for 10 minuets then turn off for 5 minuets untill the temperature and/or humidity no longer creates the conditions for ice formation.

    The heating wire will be sandwiched between two sheets of aluminum tape and there will be a rear cover placed over the rear of the reflector so the heating wire will not be directly incontact with any precipitation or ice melt.

    I have researched several heating cables and wires, but many of them get way to hot or are mineral insulated and cost too much. I pulled some heating wire out of two old electric blankets I had lying around and one of them had a wire that was just seven small strands spiraled together, the other was an acutual heating wire like the DUAL CONDUCTOR M.I. ALLOY 825 SS manufatured by Delta-Therm.
    (http://www.delta-therm.com/miheattracecables [Broken]) I would rather find some wiring like the first mentioned due to ease of application and cost.

    Might look into heating wire systems made to put under your bathroom tile -- a cheapo retrofit for non-radiant heat floors. The bit I got for my shower stall was about 200 watts and ran on 120v.
