For a wood stove, you want to have a continuous feed, complete combustion style stove. This is why pellet stoves ended up being the superior technology, followed by rocket mass stoves, then double chamber stoves. Natural gas stoves will benefit you in several ways, especially the ease of use and high temperature output for cooking, but make for poor long term heaters if not attached to a boiler or oil filled radiator system. As for fire places, all current made fireplaces will make your homes colder even with an active fire as it draws air out of the building up the chimney. if you do have a traditional fireplace insert (not a cooking hearth) you will want to have a split tube heater insert for the fire if you want to be cheap, or get a standing single chamber wood stove and pipe the exhaust up the chimney.
