Oh, and on heating and thermostats, you will find many here heating a house the size of yours entirely with a single stove. This is usually accomplished by those with newer houses and open floor plans, by placing the stove in a central first-floor living space, and allowing the bedrooms to be a bit cooler than the first floor. Heat rises, which helps move some upstairs, but most are also happy to have a slightly cooler bedroom.
In the case of your middle-age and mid-size house with modern insulation and replacement windows, this could work fairly well, on all but the coldest days. Assuming a typical four-square central hall Victorian floor plan, the divided rooms are going to create one very warm room where the stove sits, but the rest of the house might fair pretty well.
If you are able, a Outside Air Kit (OAK) will really reduce cold air draft into the house, and be the single biggest factor in how even your house feels. The lack of an OAK will force the stove to draw it's make-up air thru every distant crevice and leak in the house, causing distant rooms to get a constant supply of cold air thru their windows. The OAK relieves this situation, but assuming masonry construction (typical Victorian brick with air gap?), this is not entirely trivial.
On heating method, I used to battle to keep the house warm and even with multiple stoves running, and my family was frequently cold and unhappy. After a few years, I settled into just programming the t'stats (we have seven zones in the part of the house heated by the stoves) for the temperature we want the house to be, and then just keeping the stoves fed on a schedule that works for me (two loads per day in one stove, one load per day in the other). Using this method, I'm not using much more oil than when I was killing myself and freezing my family trying to heat without aid of the boiler, with far less work and frustration.
