When considering a boiler replacement, the primary concern should be the heat distribution method in your home. The existing heat distribution infrastructure plays a crucial role in determining the options available for your HVAC consultant. If your distribution system cannot be easily changed, it may limit the choices for the new boiler installation.

For instance, installing an air handler to distribute heat requires pre-existing ductwork. Undertaking such a project without existing ducts could prove excessively costly and time-consuming. In Canada, hot water circulation systems are the most common residential boiler applications. Various heat distribution systems are popular, including cast iron radiators, copper fin baseboard radiators, in-floor radiant heating, and air handlers.
