Just my 2 cents. I'd be looking for one rated at 7500 watts. I don't know if you have a well or the type of heating you have but 4000 watts is the bare minimum. Refrigerators, heat (oil hotwater has circulator pumps) and some lighting will use about 4000 watts. If you have a well and any electric heat you'll need more. Check out 5500 watt continous with 7500 peak rating for cost savings. I have that and it heats my house and I have 3 refrigators (wife loves to cook) the TV and some lighting. It does grunt every once in a while..
