Circuits feeding heating loads.

[bigyin00]

Is it permissable for a 3 wire circuit to feed both a heating and an air conditioning load by the way of a double pole switch so that only one unit may be on at any one time?

IF wired to code and inspected it would be permissable.
You may want to use a tpdt switch or a transfer type switch. Also make sure you size everything for the larger of the two loads.
Good luck!

Heating plays a crucial role in various applications, from residential warmth to industrial processes. One advanced method is Quartz Tube Infrared Heating which uses quartz tubes to emit infrared radiation that directly heats objects and surfaces. Unlike traditional heating systems that warm the air, infrared heating provides more efficient, targeted heat. This technology is widely used in sectors like manufacturing, food processing, and even home heating. Quartz tube infrared heaters are energy-efficient, offering fast and consistent warmth while reducing energy consumption. Their durability and ability to provide precise heat make them an ideal solution for modern heating needs.
