Hi Mike,
Lets do a quick calc. Let's say flow is a gallon a minute for 15 minutes. Let's say you like really hot showers at about 45C. Let's say room temp is 20C giving us a differential of 25C. Mass x Temperature change x specific heat.
hm less than 6000 kilojoules. Yep,
So if we assume that energy to heat water costs about $15/Mbtu (or
about 1.5 cents per MJ), then you've saved about 9 cents on that
shower. Times four showers a day for a year, and you've saved
$131 Since incoming water temp is usually more like 5 or 10C here

I reviewed your calculations andagree with them. Mine were based on a full (15.5 cu ft) bathtub (minus occupant).
Specific Heat = 4.186J per gm, per deg C
Massof Water = 439Kg
Mass of Occupant = 70Kg
Differential Temperature = 45-20 = 25 C degrees
