Boiler Ratings Explained - Heating Help

Jun 18, 2014 · This isn't about heat loss. This is about heating a LOT of metal. So . . . is the boiler a cold-start boiler (which means you have metal to heat every time it starts), or is the boiler operating on outdoor reset (where there would be less of a temperature rise each time). All of this changes depending on how cold it is outside, of course.

The heat load is the heat transferred by a heat exchanger (calculated in kW). 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

Water Heater Calculator, Formula for Time Required to Heat

Water heater Calculation: Water heater power P (kW) in kW is equal to the 4.2 times of the quantity of water L in Liters and the temperature difference divided by 3600. Hence, the required power to heat the different temperature formula can be written as, P (kW) = 4.2 x L x (T 2-T 1) / 3600. T 1 = Initial water temperature. T 2 = Final water temperature.. From the above formula, we can
