Tom - Thanks for the specifics on the freeze alarm. I need to look into one of those, even though we're not away for such a long period of time. We've got an automatic back-up generator here at the house in OH that will keep the furnace, etc. going as normal. But that won't help if something goes haywire with the furnace itself. We don't need to come back to a home with broken water pipes!
