2400 ES, 2700 ES specifications

AquaStar 2700 ES and AquaStar 2400 ES are cutting-edge gas tankless water heaters designed to deliver efficient, on-demand hot water for residential and commercial applications. These models have gained popularity due to their compact design, energy efficiency, and advanced features, making them suitable for various plumbing systems.

The AquaStar 2700 ES comes equipped with a powerful heating capacity, capable of delivering up to 2.7 gallons per minute (GPM) at a temperature rise of 35°F. This makes it an ideal choice for homes with multiple hot water outlets, ensuring a continuous supply even when several taps are in use. The 2400 ES, while slightly less powerful, offers an impressive 2.4 GPM, making it an excellent choice for smaller households or apartments where water usage is more moderate.

Both units utilize a flow sensor technology that activates the unit only when hot water is needed, which results in significant energy savings.

These models are easy to install in various locations, such as laundry rooms, basements, or even outdoors, as they are built to withstand the elements. This flexibility in placement enhances their appeal to homeowners and businesses looking to optimize space.

The AquaStar tankless water heaters also feature built-in safety systems, including an electronic ignition that eliminates the need for standing pilot lights. This not only provides greater safety but also improves energy efficiency. Additionally, they come with a user-friendly interface that allows for easy temperature regulation, giving users direct control over their hot water needs.

In terms of durability, AquaStar units are designed for longevity, with corrosion-resistant heat exchangers ensuring reliable performance year after year. This makes them a smart long-term investment for those seeking reliable hot water solutions.
