I am knocking down my old house and building a new 4000 sf house on my waterfront property on the south shore of Long Island, NY. My old house had oil for heating and hot water with electric appliances. I want the new house to have a gas range, a gas dryer and gas fireplaces, but national grid has quoted a price of $6K to $7K to run a gas line from the street to the house (the house is nearly 400' from the street). I am tempted to get propane instead, but have heard that natural gas will be cheaper in the long run, not to mention more convenient due to the lack of fuel deliveries. I plan on staying in the house at least another 10 years so what would be the best option in the long run... a) propane for heating and appliances, b) Oil heating with propane appliances, or c) spring for the extra expense of putting in a natural gas line and have natural gas heating and appliances?
