Question

I need help with this problem.

The energy consumption associated with a home water heater has two components: the energy that must be supplied to bring the temperature of ground water to the heater storage temperature, as it is introduced to replace hot water that has been used: the energy needed to compensate for heat losses incurred while the water is stored at the prescribed temperature. In this problem, we will evaluate the first of these components for a family of four, whose daily hot water consumption is approximately 100 gal. If groundwater is available at 15 degree C . what is the annual energy consumption associated with heating the water to a storage temperature of 55 degree C ? For a unit electrical power cost of 50.18/kW-h. what is the annual cost associated with supplying hot water by means of electric resistance heating or a heat pump having a COP of 3.
