how much most energy saving is generally generally in boiler water temperature

Economizers | CleanBoiler.org

For example: consider a 500 hp boiler with a gas input of 20 million BTUs per Hour. 20000000 BTUs x 5% = 1000000 BTUs ( Load Factor) 1000000 BTUs / (1200 BTUs per Gallon of 200F water) = 833 Gallons per Hour. (1000000 BTUs / 80% efficiency) = ~1.2 MCF x

Savings Project: Lower Water Heating Temperature ...

PROJECT LEVEL. EASY. ENERGY SAVINGS. 4%-22% annually. TIME TO COMPLETE. 2 HOURS. OVERALL COST. $0. Although some manufacturers set water heater thermostats at 140ºF most households usually only require them to be set at 120ºF which also slows mineral buildup and corrosion in your water heater and pipes.
