Choosing the right water heater for your home involves understanding the differences between tankless, tank, and indirect systems. Tankless water heaters offer on-demand heating, providing energy efficiency and space savings. Traditional tank water heaters store a set amount of hot water, ensuring immediate availability but may consume more energy. Indirect water heaters utilize your home's existing boiler or furnace, offering high efficiency when paired with modern systems. Your choice should consider factors like household size, water usage, energy efficiency, and installation costs.
