The answer to 'should I get boiler or' is that the choice between a boiler and a furnace depends on your specific home and heating needs. Boilers are generally more energy-efficient and provide more even, consistent heating throughout your home, while furnaces are often less expensive to install and may be better suited for homes with existing ductwork.
Boilers use hot water or steam to distribute heat, while furnaces use forced air. Boilers are typically more durable and have a longer lifespan, but they can also be more expensive to install and maintain. Furnaces are generally more affordable upfront, but they may not be as efficient or effective at heating larger homes.
