  • Hydrastone-lining
    The concept of stone-lined water tanks is not a new one, and has been proving successful against corrosion for ages. Many of the stone-lined tanks are installed are 25-30 years old. In fact, the New England area has been using stone-lined tanks for years due to their water supply being very acidic and has been devastating to glass lined tanks.
    Br> What makes the Alliance SL unique is the Hydrastone-lining. This one half inch lining protects the steel tank from the corrosive action of water. When the water first enters the tank, it is absorbed into the Hydrastone-lining permanently. This water loses its oxygen and becomes inert, non-corrosive water which then acts as a protective wall between the hot water and steel tank. This unique process and design makes Alliance SL water heaters a great choice for domestic hot water applications.

PLEASE NOTE: The product weighs 391 lbs. and may require the use of a

If you do require a lift gate at your delivery, you'll have the option to add this FREE of charge when you checkout.
