Demand water heaters - also known as tankless, instantaneous, or instant-on water heaters - are growing in popularity. These water heaters offer numerous advantages over traditional storage water heaters and are available for all major fuel types: electric, natural gas, and propane. Not only can demand water heaters improve convenience and comfort for the homeowner, they can make it easier to achieve the HERS Index Target for ENERGY STAR certification.
