The installation of a boiler typically requires the expertise of a trained and licensed professional. It is recommended to hire a qualified HVAC technician or a plumbing and heating contractor with experience in boiler installations. These professionals have the knowledge, skills, and tools necessary to install the boiler safely and according to local building codes and regulations. They can assess your specific heating needs, determine the appropriate boiler size and type, and ensure proper installation and connection to the existing heating system.  Professional installers can handle tasks such as piping, venting, electrical connections, and testing for leaks and proper functioning. Hiring a professional for boiler installation offers several benefits, including assurance of correct installation, warranty coverage, and compliance with safety standards. Attempting to install a boiler yourself, without the necessary expertise, can lead to safety hazards, improper functioning, and potential damage to the equipment.
