The Alliance™ SL works in conjunction with the boiler to provide practically limitless domestic hot water. It has a higher recovery rate than competing tank type electric, gas or oil-fired hot water heaters, insuring plenty of hot water when you need it for your active lifestyle. The Alliance™ SL is manufactured with an extremely durable Hydrastone lining, making it the perfect choice for any application particularly when water quality, hardness, softness and chlorides are an issue. When coupled with the IQ and Sage2.3 Control Systems found on select boilers from US Boiler Company, the Alliance™ SL can be configured to take priority over space heating if necessary and can automatically raise the boilers supply temperature to the tank to accelerate the speed at which the Alliance™ can recover after a significant hot water draw. This key feature is perfect for homes with multiple bathrooms, Jacuzzi style tubs and multi-head showers. To further ensure long lasting comfort and performance, the Alliance™ SL is available with an optional limited lifetime warranty.
