Burnham is devoted to pushing the limits of heating technology and efficiency. Their ingenuity is responsible for some of the most efficient products on the market today. The Alliance SL is Burnham's foray into indirect-fired water heating. Using your boiler as a heat source means that the recovery rate of Alliance SL models is superior to that of standard direct-fired or electric water heaters. Alliance SL water heaters have several inches of polyurethane foam insulation to improve heat retention and reduce energy consumption. In addition to efficiency, the Alliance SL is also designed for simplicity. All connections are easily accessible at the top of the tank, where the heat exchanger is mounted. By mounting the heat exchanger here, it may be serviced without draining the tank. Easy to install, easy to service, and energy efficient, the AL50SL is the perfect water heating solution for any application.
A 1/2" thick HydraStone lining protects the steel tank of all Alliance SL models. This lining deoxygenates the water along the edges of the tank, making it non-corrosive. HydraStone has relined tanks for some of the largest companies in North America, and now you can have that quality and reliability in your home with the AL50SL.
Burnham Control Compatible
Alliance SL indirect-fired water heaters are designed to work flawlessly with Burnham's proprietary controls systems, IQ and Sage2.1. These systems can prioritize the Alliance SL over space heating and modify the water temperature for ideal recovery rates.
Cold Water Diffuser
A cold water diffuser in the tank prevents cold water from being introduced to hot water. This improves the output of the water heater.
