This is the well cover heater I built in January 1996, and other than the bulbs (which last 5 to 7 years), it's the original.

Our well head froze the first year in the house, and our builder was kind enough to lend a small quartz heater to thaw it out. He recommended putting a 40 to 60 watt bulb inside the cover, and plug it in when the temperature drops below freezing. The heat of the incandescent bulb is sufficient to keep the temp inside the cover above freezing.
So I purchased a $1.98 USD pigtail (single bulb socket on short cord), took some stiff wire from a hay bale, and built a jig which holds the bulb up on the inside and keeps the plug out of the mud on the outside. This highly complex solution took minutes to create. The cord passes though imperfections in the cover housing and the concrete base, so it's not crushed by the cover.
When incandescent bulbs went bye-bye, I purchased a box of 'em. At current consumption I'll need to live to 200 to use them up, which I'm perfectly willing to do.
Nice setup. We can still get incandescents at Walmart here. Shrug. I bought bunch cuz they all were gonna be gone, and yet we still can get them.
Lots of folks use the light bulb trick in spring houses here, when the spring is low-flow. I have our well surrounded by landscape blocks but it doesn't really get cold enough long enough to worry about freeze-up and my well pipe exits 3 feet in the ground. If I was counting on collecting up in a tank a little-finger sized trickle out of a small spring like some folks here do, though, I'd have it heated.
