The answer to 'should I get boiler or' is that boilers and furnaces are both common home heating systems, but they have different features and benefits. Boilers use hot water or steam to heat your home, while furnaces use forced air. Boilers are generally more energy-efficient and provide more even, comfortable heat, but they can be more expensive to install. Furnaces are often less costly upfront, but they may be less efficient and can create uneven temperatures in your home.
The best option for you will depend on factors like the size and layout of your home, your local climate, your budget, and your heating preferences. If you're not sure which system is right for you, it's a good idea to consult with a professional HVAC technician who can evaluate your specific needs and provide a recommendation.
