AFUE Savings Calculator for Furnaces and Boilers

To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Mar 04, 2017 · The refurbed unit will only have a small combi boiler (30kw?) installed for hot water and heating. How would I go about calculating the hourly peak and annual gas loads? I found a formula which went something like this: Hourly - 30kw/10.76 = 2.78kw (not sure what the 10.76 signifies) Annual - 2.78 * 8 * 365 * 15% = 1221kw

Boiler Sizing Calculators | Powerhouse

Evaporator The heat load of the evaporator part of the boiler can be calculated as: φ EVAP = m& SH (h′′ − hECO 2 ) + m& BD (h′ − hECO 2 ) (2) where m& SH is the mass flow of steam before superheater [kg/s], h ′′ the specific enthalpy of saturated steam at steam drum pressure [kJ/kg], hECO 2 the specific enthalpy after economizer m& BD the mass flow of blowdown water from steam drum, and h ′ the specific

Mar 04, 2020 · Multiple heating/cooling systems: Another important new feature is calculating cost of multiple heating / cooling systems being installed in large homes (over 3000 sq. ft.), and specifying largest possible BTU lead HVAC system (s) and then the smallest size system for the remainder of the total BTU load. For example, if your heat load is 150K BTUs, and maximum residential Central AC size

Boiler Efficiency: Introduction and Methods of Calculation

A load calculation will give you the amount of heat energy required to heat your home, in BTU. This number should closely correspond to the output BTU (see above) of the furnace you select (or the tonnage of your desired heat pump). Keep in mind that the size listed by most manufacturers on their furnace models is the input BTU.
