The answer to 'furnace vs boiler' is that furnaces and boilers are both heating systems used to warm homes, but they work in different ways. Furnaces use hot air to heat a home, while boilers use hot water or steam. Furnaces are generally less expensive to install and operate, but boilers can provide more even, comfortable heating and are often better suited for homes with radiators or underfloor heating systems.
When choosing between a furnace or boiler, consider factors like your home's size, layout, existing heating system, and your budget. Furnaces are typically a more cost-effective option for smaller homes, while boilers may be better for larger homes or those with specific heating needs. Consulting with a professional HVAC technician can help you determine the best heating system for your home.
