What is DOE heating capacity MBH?
• Gross output MBH = Heating capacity MBH = DOE capacity MBH: The thing about these three is they all mean the same thing. Almost. They can be defined as the rate at which the boiler transfers heat to the system water, assuming the heat loss through the jacket is wasted.
What is MBH in boiler rating?
MBH – 1,000 BTUs per hour. It is a rating that you might see for various types of HVAC system, including natural gas or propane furnaces. It is most commonly used for boiler systems and large tankless water heaters.

BTU is how much heat is produced at one instant, BTU/hr is the amount of heat produced in an hour. MBH is 1000 BTU/hr.
How much BTU boiler do I need?
Boiler Capacity An easy rule-of-thumb for BTU requirements is to figure that you need about 50 BTU per square foot of interior space in a cold climate; 35 BTU per square foot in a moderate climate; and 20 BTU per square foot in a hot climate.
How do you calculate MBH?
Divide the amount of Btus per hour by 1,000 to calculate the amount of MBH. For example, the amount of Btus per hour is 20,000. Dividing that by 1,000 would result in 20 MBH. Multiply the amount of watts by 0.293 to calculate the amount of MBH.
