An electric water heater held at 120° f is kept in a 60°f room. when purchased, its insulation is equivalent to r-5. an owner puts a 30-ft^2 blanket on the water heater, raising its total r value to 15. assuming 100 percent conversion of electricity costs 6.0 cents/kwh, how much money will be saved in the energy each year?

Total saving would be of 36.917 $\yr

Explanation:

Given Data:

Degree F

Degree F

A = 30 ft^2

%

Heat loss before previous final value

                                                              = 360 Btu/hr

Heat loss after new value

saving would be

                           = 616.1782 kw hr/yr

$

         = 36.917 $\yr

i mean i gues
