Oil heating systems use fuel oil to generate heat for residential and commercial spaces. These systems typically consist of an oil storage tank, a burner, and a heat exchanger. The burner ignites the oil, producing hot gases that heat water or air, which is then circulated throughout the building. These systems are known for their efficiency and ability to provide consistent warmth, especially in colder climates. Regular maintenance, including oil delivery and system checks, is essential to ensure optimal performance and safety. Oil heating is often compared to other systems like natural gas or electric heating for its unique benefits and drawbacks.
