Steal a 220 leg for lightbulb


I have a well where the pipes out at the wellhead are freezing up in this cold snap. I'd like to put a lightbulb in the housing to keep things warm enough to not freeze. The only power out there is the 220 for the well pump and it's about 100 yards from the house. I don't really want to dig a new 100 yard ditch in frozen ground to bury some 14/2 just for a lightbulb.
Can I tap one leg of the 220 supply for the pump to power the lightbulb?
(I understand the pump needs a dedicated circuit by code)

I think I have found the answer to my own question.
Technically, yes. But only if an insulated neutral is available (which isn't always the case).

Go to an electrical supply house and get a 220 socket and bulb---or get a small 220 baseboard heater---just a thought---

It's actually almost never the case.
In all my years I have never seen a neutral run to a well head. Even in a pump house where it would be a benefit.
I have seen separate circuits run though.

Do this.

It is very unlikely you have an insulated neutral ran to your well.

240 to 120 step down transformer. You can find 100 watt for less than $20. 300 watt for less than $30.

Thanks for the good answers.

Just to complete my understanding a little more, could I technically just wire two 120v lights in series instead of the normal parallel setup.

I get why this is maybe a bad idea for future-proofing against people who don't know what I did, but my pipes are freezing now and my access to other options is limited mostly to mail order.

If it were me, depending on the size (amperage) of the pump I'd put in a small pump house heater made specifically for this application. At 500 watts it's only 2A @ 240v, so putting it on the pump circuit is entirely feasible.

Exactly, those are what I install, why do people get the notion a light bulb will stop anything from freezing?

Maybe I don't understand the situation but I don't think you'd want to tap the line going into the wellhead- it's downstream from the pressure switch and pump controller, which where I live, are both normally located in the basement by the pressure tank.

Pump house, not well head.

Varies by location I'm sure.
