boiler costs & installation
Boilers are more expensive than furnaces. Mid-efficiency boilers cost anywhere from $2,500 to $4,000, while high-efficiency boilers run $5,000 to $10,000. Those prices include installation, but keep in mind that installing a boiler is more expensive than installing a furnace because the process is more complex.emoval and haul away of the old furnace usually costs $300 to $1,000, depending on size and difficulty. As with boilers, a new chimney liner for a high efficiency unit will cost anywhere from $500 to $1,500, with liners for gas units priced on the lower end of that range and liners for oil units on the higher end.
