Large Volume Solar Tanks

Niles Steel Tank has developed large volume storage tanks coupled with internal 1-1/2” O.D. heating coils.

• Each coil has 14.2 sq./ ft. of heating surface designed for slower gpm rates which solar systems operate.
• Internal coils are single wall coils and can be positioned in almost any configuration in the tank.
• Depending on the diameter and height of the tank we can pack each tank with as much heating surface that is physically possible.

By utilizing multiple coils, different solar panel placement designs can be realized. Morning or afternoon sun can be captured, back-up systems can be refined and you can capture more of the sun’s energy and design a “smarter” tank. Multiple coils allow for modular heating zones within the tank that can be “turned on” or “off” based on the load.

In today’s world of modulating boilers and demand for high efficiencies, saving money is the goal. By utilizing multiple coils in the tank, each coil becomes a separate heating “zone” which produces more efficient firing rates and faster heating capabilities.

For quote generation, all we need to know is the tank size, number of coils, insulation or not.

• Select your tank consider door openings and ceiling heights.
• Refer to our coil chart below to see how many coils will fit into your tank. You can tell us where to place the coils later and we’ll do a sign-off drawing for you.
• Determine if you would like the tank to be top-coated with R-16 spray on insulation. Consider door openings and ceiling heights knowing that topcoat will add approximately 6” to the diameter and 3” to the overall height of the tank.

Please check our solar calculator which will help you if your chosen product can produce your desired results. The solar calculator is designed to confirm your choice on number of coils and tank size. It is not intended to guide you on what to use, but it will tell you “If” you choose “X”, your outcome will be “Y”.
