When in cold country, I always kept a smallish generator. I like the Honda for quite when it is a small load. But then as I wanted to have other things run, I went for other units from the big box stores. I arranged an extension cord to power the furnace as well as some other things like the frig and a couple lights. I did not try to power them all at the same time but assumed that I would not be sleeping much and would rotate the equipment to minimize the load. One major thing to keep in mind is that you will not be likely to use it enough to wear it out so even a sub-standard unit may be fine. The second thing to remember is that nothing is harder on a power unit than setting unused. Either set a routine and run it up to full temperature every couple months or drain all the gasoline out of it and let it run until it dies. This keeps the gunk in the gas from setting up in the carb. Nothing worse than keeping a genset for years, only to find it won't start when the power is out?
