What will it cost to operate an electric boiler?
Electric consumption: (KW rating) x (#hours of operation) x (KW/HR charge) = cost per month. Normally, the customer will utilize 60X or less of this amount. Electric demand: In the U.S.A., the electric utility company charges companies a “demand charge” each month equivalent to the peak amount of electricity used during a 30 minute period during the month: (KW rating) x (demand charge) = demand cost per month Water feed costs: With weekly blowdowns, it is not necessary to use special water in these boilers because of their larger pressure vessel and specially designed heating elements. We do suggest “softened” water if the normal water is very hard. This allows the blowdown to work better and reduces hard calcium buildup within the pressure vessel. Distilled water should not be used because of its expense. To calculate water usage: (B.H.P.) x (4.2 gallons per hour) x ( hours of operation) = water used (B.H.P.) X (l5.9 liters per hour) X ( hours of operation) = water used This formula c
