Below is an overview of current market pricing for 300 BHP (Boiler Horsepower) steam boilers, with typical sale prices ranging from $50,000 to $100,000. Prices vary widely depending on boiler type , fuel configuration, pressure rating, trim packages, and whether the unit is new or used.

1. Budgetary Pricing for Packaged Firetube Boiler

For a simple, packaged firetube boiler (no auxiliary equipment, standard trim, natural‑gas/#2 oil burner, 150 psig design), budgetary estimates put the 300 HP unit at around $60,000 (FOB factory). These figures assume:

  • Steam output: ~10,350 lb/hr

  • Design pressure: 150 psig

  • Efficiency: ~85%

  • Standard boiler trim: gauges, safety valves, LWCO, burner controls, insulation

Note: These “ballpark” figures exclude taxes, freight, installation, water treatment, economizers, and other accessories, which can add 30–60% to the base boiler cost.

2. New High‑Efficiency Condensing Steam Boiler

We offer high efficiency condensing boilers up to 300 hp. These units typically have the following features:

  • Operating pressures up to 250 psig

  • Dual‑fuel burners (natural gas/propane)

  • Turn‑down ratios of 8:1 or better

  • Efficiency: ~97%
  • Emissions as low as 5 ppm NOₓ

Fully‑trimmed 300 BHP condensing boiler can range from $80,000 to $100,000 when configured for compliance with stringent emissions standards and including economizers or advanced controls.

3. Factors Influencing Final Cost

  1. Boiler Type: The thermal efficiency of traditional boilers is relatively low, while the thermal efficiency of condensing boilers can be increased by 10%-20%. Long-term operation can save fuel costs

  2. Fuel and Burner: Dual‑fuel burners and low‑NOₓ configurations add 10–20% to base price.

  3. Trim and Controls: Advanced controls, economizers, feedwater systems, and water treatment can add 30–50%.

  4. Installation: Site prep, piping, wiring, and commissioning typically cost 50–100% of the boiler price.

  5. Local Codes and Permitting: Compliance with local emissions and safety codes may require additional equipment or modifications.

Conclusion

For a 300 BHP steam boiler, expect a base equipment price in the $50,000–$100,000 range,Always obtain detailed quotes—including all trim, auxiliaries, freight, and installation—to determine the final turnkey cost.
