Winterizing house
I've heard conflicting opinions on this and was wondering what you do. If the house has no heat at all for the winter should we expect damage of any kind? Once it snows our road won't be accessible ...

Be careful of leaving the heat on and shutting off the water. If you have forced hot water heat, the boiler makeup will not happen and the boiler will run at a lower pressure. I had this happen last year in spite of explaining this all the the local handyman that visited the house once a week. When I got home, one of the circ pumps was frozen.
You can have a separate water line run to the boiler so you can shut off the rest of the house, but this leaves you open to basement flooding if a PT valve fails or the expansion tank diaphragm ruptures. If you have water pressure on the boiler all winter, I would run the PT valve overflows (boiler and water heater) to a sump or outside.
