My wife and I are purchasing a home that needs a new oil boiler. There is no asbestos and it is where the domestic hot water comes from. The sellers are going to be reducing the price of the home by an amount we negotiate. Our inspector told us to expect to pay about $3500 for a new boiler. It is baseboard hot water heat and the house is a ranch of 1380 sqft. There is a hatchway for easy access to the basement. Is the $3500 a good place to start negotiations or is the "average" price higher or lower for a new boiler?
A replacement boiler will vary depending on features and size, which will vary according to local climate, local labor costs and construction of the house. Why not have a HVAC contractor provide a bid for the work? After you move in, you can get additional estimates to make sure you are getting what you want at the best possible price. Without more information, we are going to have a hard time second guessing your inspector's estimate.
