Timer for Recirculating pump

Member Posts: 30
Had a Knight 8o & Indirect tank w/ recirculating line installed last year, Love It!
Would like to improve the gas usage a little more, by installing a timer on the recirculating pump. Is there any down side to installing a 7 day timer w/ multiple on/ off settings? IE- 6-9Am on, 9am-5pm off, 6-10pm on ETC. Figure might as well squeeze a little more efficiency out of the system.
Thanks

Timer and System Loss
Setting a timer to charge the lines on peak demands is a good way to save. And Insulating the lines are also needed to save energy and meet Federal energy codes .There was an error rendering this rich post.

The only downside
that I can think of is waking up at 5 am (or any other "off" hour) and have to wait for the hot water.0 -
Timer or Motion Sensor ?
Another method of control is a motion sensor (or switch) to turn the DHW recirculation pump ON. Would need a motion sensor located wherever you need instant hot water - like at a shower but not necessarily at a sink. See:
http://www.toolbase.org/Technology-Inventory/Plumbing/hot-water-recirculation
or google: hot water recirculation motion sensor.
Constant DHW recirculation wastes electricity to run the pump and wears out the pump - but more importantly it wastes heat that is emitted from the constantly hot pipes.
Which control method is best depends on your situation.

How about
A nice 7-day programmable timer, like the Intermatic ET-1700 series..can support up to 14 events daily.0 -
