What type of system do you need?
Choose the primary output your application requires. Not sure? Hot Water is most common for buildings.
How much heating capacity do you need?
Think in terms of your building or process load. When in doubt, consult an engineer. 1 MBH = 1,000 BTU/hr.
What operating pressure is required?
Most commercial heating systems run at low pressure. High pressure is typically required for industrial process steam.
What fuel is available at your site?
All Superior Boiler products support multiple fuel options. Dual-fuel provides the most flexibility for fuel switching.
What's your efficiency & installation priority?
Condensing boilers achieve the highest efficiency but require lower return water temperatures and Category IV venting.
