An electrical water boiler is used for supplying steam to the process in a food industry. The rating of the boiler is 30kW. It is proposed to replace this boiler with a new energy efficient boiler. The new boiler costs $125,000. The new boiler can save 30% energy at 60% loading when compared with the old boiler. The erection and commissioning cost of the new boiler is $20,000. The resale value of the old boiler is $10,000. The maintenance contract for the new boiler is $8000. The boiler operates for 6000 hours in a year. The cost of electricity is $4 per kWh. Calculate the payback period.
