Niles Steel Tank offers a full line of both commercial and residential solar tanks. Approved in many systems with OG300 certification, the Niles solar tanks are already to go. We offer solar tanks with back-up systems for electric (2 elements), boiler (hot water) or under-fired gas models to choose from. We also have a full line of solar tanks with no internal coil but have 2) electric heating elements as back up.
Our larger commercial custom built solar tanks have multiple internal coils designed specifically for slow gpm which is ideal for solar pump rates. These large solar tanks are custom built precisely for your project and can be ordered with our R-16 spray-on foam insulation. By introducing multiple coils into the tank, you can add more array’s on the roof to maximize each coils heating potential. Perfect for applications where faster recovery times are needed.
