The answer to 'cost of boiler' is that the cost of a new boiler can vary widely depending on several factors. Typically, the cost of a new boiler for a home ranges from $3,000 to $10,000 or more, installed. The specific cost will depend on the size and type of boiler, the fuel source (gas, oil, or electric), the brand and efficiency rating, as well as the complexity of the installation.
Other factors that can influence the cost include the age and condition of the existing system, the accessibility of the installation site, and any necessary upgrades to the home's plumbing or electrical systems.
