Price-Check on Gas Bill

We are renovating a four story brownstone and are living in the garden level ONLY. We have a gas powered hot water heater and a gas boiler and an electric stove. We have three radiators in the garden level, and have three radiators in the rest of the house (one per floor above us) and use hot water for all for the basic things. Our last Keyspan bill was $184. This month’s bill was $440. Is $440 a normal bill for such a light load? I am scared to thin how high it will be once we install all of the heating upstairs! Second question- We are a one family, but Keysp is billing us as a three family—which is cheaper?
