The answer to 'boiler vs' is that boilers and furnaces are both heating systems used to warm homes, but they have some key differences in how they work and what they're best suited for. Boilers use hot water or steam to distribute heat, while furnaces use forced air to circulate warm air through ductwork.
Boilers tend to be more energy-efficient and provide more even, consistent heating compared to furnaces. They're also often better suited for larger homes or homes with radiators or baseboard heating systems. However, boilers can be more expensive to install and maintain. Furnaces are generally less expensive upfront and may be a better option for homes with existing ductwork. The right choice depends on the size and layout of your home, your heating needs, and your budget.
