If the boiler is in poor condition and slated for replacement, the balancing work should not be attempted until after the boiler is replaced. Building owners should also confirm the return piping does not leak, especially in buried returns.
Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

Load management measures, including optimal matching of boiler size and boiler load, can save as much as 50% of a boiler's fuel use. Rule of Thumb Energy Savings An upgraded boiler maintenance program including optimizing air-to-fuel ratio, burner maintenance, and tube cleaning, can save about 2% of a facility's total energy use with an average simply payback of 5 months.
