An electric water heater held at 140 °F is kept in a 70 °F room. When purchased, its insulation is equivalent to R-5. An owner puts a 25-ft2 blanket on the water heater, raising its total R value to 15. Assuming 100 percent conversion of electricity into heated water, how much energy (kWhr) will be saved each year? If electricity costs 8.0 cents/kWhr, how much money will be saved in energy each year?
