Downspout water heater

My sumppump empties to a buried plastic 4" black plastic pipe with a 90 degree trap that faces up. With that outlet being exposed to the Indiana freeze, I am hoping there is a small electric heater, I envision about the size of a silver dollar, that I can drop in this water to keep it thawed. Do they make such a device?

While a birdbath heater would be a good option it would need to be immersed in water to keep from overheating. Another, possibly better option would be gutter heat tape. Different lengths are available. Be sure to get the ones for roofs and gutters, not the one that wraps around the outside of the pipes.

Why would there be a trap in the ground ?

I'm with PJ and also what do you mean it's facing up?
That would even make less since.

It is gravity fed towards the street. Completely underground. Then probably rises 6 inches to flush out to the street. I found a 7.5 W aquarium submersible heater. I will just drop this in the hole and issue solved. This is a new house to me and this is what I have.

OK.... so it's a 90 fitting and because of improper slope.... it stays full of water.

Yes pj. Exactly. My 1st winter here. I want to be sure this don't freeze in event the pump need to discharge. I don't think 7.5 watts continuous for 3 months will make a noticeably diff on energy bill. Not entirely sure this little guy will keep it thawed at 0 degrees. Guessing game

Would injecting air (aquarium pump) into the sump line work to keep the water from freezing? This could be done inside the house & would eliminate the long cord, restricting the discharge with a fragile glass tube, etc.
