Just getting out of the winter, although it keeps snowing here in Chicago. Recently moved into a new home, and have a concern regarding the main water line coming into the building.
The water line enters in the basement, at about 6 feet below the surface. Ever since we moved in, we have been fighting trying to keep the basement warm. But where the water line comes in (small little access space between outside wall and inside wall), is just super cold.
I've had a temperature sensor in there for the last 3 weeks, and even when its been 70+ outside (rare lately) the access area for the water line never went over 57.
I understand that since its below the surface, its going to take a while to warm up. Where my concern is:
1 - How is this going to work in the winter? Its keeping the basement cold now, at that depth under ground, does it get any colder?
2 - We added insulation behind the water pipe between the external wall and the pipe to seal off any drafts as best we can. It helped, we got the temperature up a bit more (54 to 57). Im cautious of putting insulation in front of the pipe between the inside wall and pipe as I feel some of the building heat needs to keep that pipe warm. Or are these main water feed pipes built for the cold?
What are the thoughts of helping keeping the basement warmer and not risking reducing the the heat (if needed) to the water pipe?
