Ultimately, we want to have year-round water in a building roughly 300 feet (90m) from our well/house. Where we live the average winter temperature is ~14 farenheit (-10 celsius), and bottoms out around -40 on the coldest of cold days. The frost line for our general area is somewhere around 5 - 6 feet (1.5m). The issue is that we have 0 - 24 inches of soil, and then bedrock.
So - how to do we get water to not freeze in the winter when we're faced with low temperatures and bedrock preventing us from running it underground? I've looked at products like heat tape and Heat-Line. Both seem expensive and not-ideal, but I'm pretty stuck for options.
We have water in our house that comes from the well, how does that not freeze? I have no experience with plumbing whatsoever. Any ideas?
