Water heater selection guide calculator-Realize which type of water heater has minimum energy bill anually and minimum CO2 emission


Note: You can only add values to right column of inputs.
One person uses 15 liter water for bathing. 15 liter bucket should get filled within 10 minutes. Number of people may be 3, so total water requirement, daily, will be 15*3=45 lit with total 30 minutes waiting time. Also, if hot water is to be used frequently, buying storage tank type heaters will be advisable, because starting of any electrical equipment takes 3 times of its rated power for miliseconds, mostly due to capcitor charging and this may increase power consumption with frequent on off. Another thing to be noted is, the electricity bill also acounts the max kW (peak) used in month as a seperate charge, so electric heater should have low power rating. 

NO is emitted in power plant with temperature of 1200 dgree celcius. Since there is no sulphur in gaseous fuels so SO2 is zero. It is assumed that no NO is produced in PNG and LPG heating.
