Stay with a deep cycle. Problem is that you probably don't have one now. Most dealers install a combination starter/deep group 24 marine battery which isn't a deep cycle battery.
The furnace most likely is your heaviest load. If you run heat all night a group 24 battery will last one night. You probably have an LP detector and possibly a CO detector that is a constant draw. With the refrigerator you might have a drain of 1 amp per hour or more.
The typical group 24 combo battery has 80 amps. Just the basics are likely draining 24 amps per day without running lights, fan, or furnace.
The answer is to have more batteries and charge once per day for a couple hours. You don't want to regularly drain the battery more than 50%. Many of us use 6 volt golf car batteries because they give more amps per dollar.
Use the IOTA, it is a good charger especially if you have the charge wizard.
