Michelle, praying for a quick fix to the furnace. If your worried about the pipes just let the water run very slowly that way there is movement. I had to do that when we lived in a mobile home in SC our pipes were not insulated and it was getting down into the teens. Unless it will be a hard time on your water pump if you have a well?
Also prayers to all those that need it at this time of year. And hugs via the internet.
