Heating of water is a significant cost for most households, with about one third of all household
water consumption going to either showers or baths. If a low efficiency shower head is used,
approximately 18 L of water are used per minute of shower time. A high efficiency shower head
reduces that to about 10 L of water per minute. If water enters the hot water heater at 14 oC and is
heated to 49 oC to be used, determine the daily cost of each of the following:
a) 5 minute shower with high efficiency shower head at off-peak times.
b) 5 minute shower with low efficiency shower head at on-peak times.
c) 10 minute shower with high efficiency shower head at mid-peak times.
d) 15 minute shower with low efficiency shower head at on-peak times.

e) how much difference would there be in the annual costs for a
family of 5 if all 5 had the least expensive shower instead of the most expensive shower?

Converting Joules to KWhrs

1KWhr = 3.6x10^6 J

Cost of electricity

off peak = 12.6 cents/KWHr

mid peak = 18.6 cents/KWHr

On peak = 24.6 cents/KWHr
