The answer to 'average cost for boiler' is that the typical range for a new boiler installation can vary significantly, but generally falls between $3,000 to $10,000 or more. The final cost will depend on factors like the type of boiler, size of the home, complexity of the installation, and your local market conditions.
Boilers come in different fuel types (gas, oil, electric) and efficiency levels, which greatly impact the price. High-efficiency condensing boilers are more expensive but can save you money on energy bills over time. The cost will also depend on whether you need to replace the entire boiler system or just the boiler unit itself. Additional factors like ductwork, piping, and permits can further affect the overall project cost.
