My well control setup is in the unheated barn. I tried to keep the pump room heated for a few years but am tired of replacing pressure tanks that freeze up over the winter due to electricity being lost. I'm wondering what would be wrong with keeping the pressure switch where it's at (easier to drain in fall) and putting the pressure/bladder tank in the house. What do you think?
Without knowing the whole circumstance of what you want to do or the complete set-up of piping & control, allow me to say that the location of the bladder tank does not matter as long as you can control the operation of the well pump. I think that the best answer would be to bury the water line between the barn and house deep enough to prevent it from freezing and to move the tank and pressure switch to he house. You could dig a trench and put the water line and any wiring in that trench. This way nothing will freeze.
