    I need to determine the approximate wire size used in a space heating element (my ancient heat pump). I estimate the length of the coiled element to be approximately 35 inches. The coil is U-shaped with a spacing of 5 inches. The input voltage/current is 240VAC at 50 Amps. The cold resistance is between 10 and 11 ohms on the 3 elements still intact. My best SWAG is #26 but I could be way off base.

    Yup, I know I could take the elements out and measure everything, but that would be WAY too easy. Hopefully one of the HVAC experts out there can provide some input??

    Thanks!

    A. Thats not wire.

    B. Have a contractor come and fix your back up heat for you.

    How many times must one fix something before it is fixed?

    if you're getting those ohm readings then there's no need to replace the elements. Have someone come and fix it for you.
