Hot Water Generators

Niles Steel Tank Hot Water Generators are equipped with 2-or 4-pass, single or double wall construction, U-bend heat exchangers. They are designed primarily for natural convection in the tank and can be operated by passing either steam or water through the coil to heat the tank contents.

Large heating capacity in small spaces makes this heater particularly suitable for boiler rooms with low headroom. Choose from vertical and horizontal configurations including top-coated or jacketed and insulated.

All tank fittings can be NPT, flanged or grooved end. Most generators are porcelain enamel (glass) or epoxy lined for potable water applications up to 180°F and160 PSI max. For higher temperatures or special applications, we offer 316L stainless steel tank construction.

Heat exchangers are built with your choice of copper, stainless or copper nickel tubes. All tubesheets are 304 stainless steel unless requested otherwise.

Hot Water Generator Controls are available for Water to Water and Steam to Water systems. Regulators are available as self-operating, electric, or pneumatic. If the regulator is not specified for self-operating, electric, or pneumatic then self-operating will be the default system.

Each control system is designed specifically for each Hot Water Generator System, please consult the factory for sizing and pricing.  Controls are shipped loose and must be assembled at the job site.  Niles Steel Tank uses Trerice regulators.
