That is one heck of a well house. Two years ago, I tore out my storage tank and moved the pump out to the dug well (Wife was tired of the noise). The well has an insulated 4'x4' box over it and is heated by a a 90 watt incandescent bulb. Since I am now pushing water instead of sucking water...the pump is on very minimally. This is a 1hp Grundfos jet pump and operates on pennies a day. Not to shabby for this frigid climate. I did plumb in a "Winter Watchman" and a trouble light to let me know if the bulb burns out. This bulb is on its 3rd year and is on 24/7 from October-May.
