Top mount removable heat exchanger with double o-ring design for easy installation and service and eliminates the need for welds between the piping and the tank.
Hydrastone-lining protects effectively against corrosion.
Alliance SL™
27, 35, 50 & 70
Two to three inches of polyurethane foam insulation combined with the stone lining resulting in extremely low standby heat loss.
Larger coil diameter and spacing designed and positioned for maximum heating output and minimizes build-up.
Unique cold water diffuser to increase output by 20 percent.
Heavy gauge steel helps increase integrity of the tanks
Note: No anode rod required
Proprietary TPI control accurately controls the output water temperature and helps eliminate tank “overload.”
The Alliance model AL119SL utilizes a side mounted coil that is supplied separately.
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.
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.
