Should the outside unit be covered in the winter?

When homeowners ask about adding insulation around their water heater, I usually advise against it. It can create a cozy haven for mice and other pests, attracting them to the warm space and potentially leading to chewed wires. This is especially true in rural areas of Western New York, where we see a lot of rodent damage caused by insulation.

Frankly, I don’t know what it is about the wiring in these units, but it seems like mice find it irresistible. They just love to gnaw on it!
