As with most things in life, there is a tradeoff here.

Depending on the situation, up to 15,000 gallons a year of water that
would otherwise flow down the drain while you wait for the hot water to
arrive will be saved as hot water will be virtually instant on every
time. That's on the order of $60 or more per year in water/sewer costs
saved (exactly how much depends on where you live). The pump will
consume maybe $10 of that in a year. The extra utility costs in keeping
the water at a usable temp in the hot water lines during usage hours is
hard to quantify but lets say its an extra $15 a year.


I would imagine that would be an interesting situation. Perhaps whomever
wrote the marketing material for the pump got a little carried away?

We have a house on metered city water with two residents and our *total
consumption* is 19,000 gallons/year.



WOW, Frugal with water are we!! That is less than 2000 gallons a
MONTH!!! With two people here, no outside watering of flowers, trees,
shrubs, grass, two showers a day, three to four tubs of laundry a week,
cooking and cleaning, we are usually about 5,000 gallons a month or
60,000 gallons a YEAR, triple your useage.
